The document discusses adenovirus, a common pathogen affecting humans and animals. It notes that adenovirus was first discovered in 1953 from plasma clot cultures and throat washings of military recruits with respiratory illness. Adenovirus is classified into 6 subgenera with several serotypes. It is a non-enveloped, double-stranded DNA virus around 70-75nm in size with an icosahedral capsid. Adenovirus causes diseases like pneumonia, acute respiratory disease, pharyngitis, epidemic keratoconjunctivitis, acute follicular conjunctivitis, and pharyngoconjunctival fever. Diagnosis involves testing samples from the throat, eyes, urine or feces

Australian mosquitoes take a bite out of California
An Australian mosquito species, Aedes notoscriptus, has been found for the first time in California. It is able to spread viruses like Ross River virus and Barmah Forest virus under laboratory conditions. Aedes notoscriptus lives in natural and artificial containers near human habitats. It can travel up to 200 meters and be spread greater distances through human transport. While a minor public health risk compared to Aedes aegypti and Aedes albopictus, it is a reminder of how easily exotic mosquitoes can spread. More research is needed to understand interactions with existing species and whether it consists of complex of cryptic species. Controlling mosquito habitats through education, source reduction and larviciding offers options
Determination of the Prevalence of Bluetongue Disease in Goats in Siirt Provi...
Bluetongue disease is a disease caused by the bluetongue virus in the Orbivirus genus of the Reoviridae family. The disease can be transmitted by ticks, sperm and vertically but is mainly spread by the Culicoides type flies. While the disease is naturally observed in cattle and sheep, it is more rarely observed in goats. This study was carried out to determine the presence of bluetongue infection in goats raised in Siirt province serologically and to obtain information about its prevalence in the region. The material of the study consisted of a total of 372 goats over one year of age raised in Siirt province. For laboratory analyses, 5 ml blood samples were taken from the jugular vein of goats to tubes without anticoagulant. The samples were centrifuged at 3000 rpm for 10 minutes, and the sera were transferred to Eppendorf tubes and stored at -20 °C until analysis. The serum samples were analyzed by the ELISA (Thermo Scientific Multiskan Go) method using the commercial test kit (Bluetongue Virus VP7 Ab Test Kit, IDEXX). The results were evaluated as positive and negative. Of the 372 goats constituting the material of the study, 252 (67.74%) were seropositive and 120 (32.26%) were seronegative. As a result, in addition to measures for quarantine and vector control in the fight against the disease, it was concluded that vaccines specific to virus serotypes should be used and comprehensive and planned studies should be carried out in relation to the disease in the region and the country.

This document summarizes entomological research conducted at a field site in southern Zambia. The research included (1) CDC light trap and pyrethrum spray catches to collect mosquitoes, (2) identification of mosquitoes using morphological and molecular techniques, (3) analysis of blood meals to identify host sources, and (4) testing of insecticide resistance in local populations. Over 800 female Anopheles mosquitoes were collected, with the majority being Anopheles arabiensis. Studies also examined the seasonality of biting behaviors and the efficacy of existing long-lasting insecticide-treated nets. The research aims to support malaria control efforts in southern Zambia.
Surveillance of AVI
The document summarizes a study that collected cloacal swab samples from 200 waterfowl in Erie and Mercer counties in Pennsylvania to test for avian influenza virus (AIV) subtypes. Using RT-PCR analysis, the study found that AIV was not present in the sampled waterfowl. While no AIV was detected, previous studies have found AIV in waterfowl populations at the same field sites. The lack of detection could be because AIV is only shed for a limited time after infection. Continued surveillance is important to assess the risk AIV poses to wildlife and humans.

Researchers in an endemic area of American Visceral Leishmaniasis followed 60 dogs over one year to study the disease's prevalence through serological, clinical, and parasitological testing. They found that while 41.7% of dogs were initially seropositive, by the end of the study 50% were seropositive, suggesting control measures need modification. Clinical symptoms were observed in some dogs but most showed no symptoms.
Historical prevalence and distribution of H7N9 among wild birds
CDC Emerging Infectious Diseases published a paper (Volume 19, Number 12—December 2013) on the Historical Prevalence and Distribution of Avian Influenza Virus A(H7N9) among Wild Birds. A very interesting document, it provides a better understanding on transmission of H7N9 under wild birds.
In this paper, the authors reviewed 48 published studies that listed findings of influenza A virus haemagglutin type H7, or neuramonase N9 viruses as well as H9N2. The prevalence was calculated as the number of positive samples divided by the by number tested.
H7N9 has been rarely reported from Delaware (USA), Alberta (Canada), Guatemala, Spain, Egypt, Mongolia and Taiwan but has not been reported from Russia, Japan, South Korea or China from birds sampled between 1976-2012.
The outcome? If you were planning wild bird surveillance to track H7N9 spread in these non-poultry animals, you'll need to sample >30,000 wild birds to find 1 positive for H7N9 (its Asian prevalence was 0.00931%).
That's a rare bird.
This is just a rough gauge of course because it is entirely dependent on when, where and how thoroughly bird populations were sampled, how they were sampled, what they were tested with and how the sequencing methods performed. It also focuses on HA and NA genes, at the expense of other internal influenza gene segments which also have an important role in the assemblage of new viruses.

The genomes of four tapeworm species reveal adaptations to parasitism
The genomes of four tapeworm species reveal adaptations to parasitism. The genomes range from 115 to 141 megabases and show maintenance of synteny with blood flukes but extreme losses of genes and pathways found in other animals, including 34 homeobox families and stem cell fate determinants. Tapeworms have specialized detoxification pathways, metabolism finely tuned to rely on host nutrients, and expansions of heat shock proteins and known antigen families. The genomes provide insights into tapeworm evolution and identify potential new drug targets, furthering development of urgently needed treatments.

The study aimed to recapitulate key findings from the Phase IIb Step Trial of a Merck Ad5 HIV-1 vaccine in rhesus macaques. Rhesus macaques were infected with Ad5hr and immunized with an Ad5 SIV vaccine or empty vector. They were then challenged with escalating doses of penile SIV exposure. The Ad5 SIV vaccine induced CD8+ T cell responses in 70% of monkeys, similar to humans in the Step Trial, but did not protect against SIV infection. At the lowest SIV dose, 2/9 Ad5-seropositive monkeys immunized with the Ad5 SIV vaccine became infected compared to 0/34 in

Ronald Ross and Charles Louis Alphonse Laveran made early discoveries about malaria transmission. Ross demonstrated in 1897 that malaria parasites could be transmitted from infected patients to mosquitoes, while Laveran first observed parasites in the blood of malaria patients in 1880. Malaria remains a major public health problem in parts of India, especially in the northeastern states, with P. falciparum and P. vivax the predominant species. In Andaman and Nicobar Islands, a study from 2010-2016 found over 8,000 confirmed malaria cases, though the annual parasite incidence declined over this period. Prevention strategies for malaria include indoor residual spraying, insecticide-treated bed nets, larval control, chemoprophylaxis, and

This document discusses viroids, virusoids, and prions - three types of acellular infectious agents. It notes that viroids are small, circular RNA molecules that can self-replicate and cause diseases in plants. Virusoids are subviral RNAs that require a helper virus to replicate and infect plants. Prions are misfolded protein particles that can induce normal proteins to also misfold, leading to neurodegenerative diseases like Creutzfeldt-Jakob disease in humans and scrapie in sheep. Unlike viruses and viroids, prions contain no nucleic acid and are extremely resistant to destruction.

Lecture enteroviruses
Enteroviruses are a genus of picornaviruses that replicate in the gut. There are at least 71 serotypes including polioviruses, coxsackie A and B viruses, echoviruses, and newer enteroviruses. They are single stranded RNA viruses with icosahedral symmetry that are stable in acid pH. Poliovirus was first identified in 1909 and causes the disease poliomyelitis, which can result in paralysis. The Sabin oral polio vaccine uses live attenuated poliovirus grown in monkey kidney cells to induce long lasting immunity after multiple doses.

Important alphaviruses that cause encephalitis are eastern equine encephalitis virus, western equine encephalitis virus, and Venezuelan equine encephalitis
Nitrogen cycle.ppt
Nitrogen is a key nutrient for plants but it exists primarily as inert nitrogen gas in the atmosphere. The nitrogen cycle describes the process by which nitrogen is converted between various chemical forms as it moves between the atmosphere, soil, organisms, and various environmental reservoirs. Key steps in the nitrogen cycle include nitrogen fixation by bacteria, nitrification of ammonia to nitrites then nitrates, assimilation of nitrogen by plants and animals, ammonification of organic nitrogen waste by decomposers, and denitrification of nitrates back to nitrogen gas. The nitrogen cycle is essential for providing plants with nitrogen needed for growth while enriching soils with nutrients.
Psychobiotics
Psychobiotics refers to live bacteria that may provide mental health benefits by affecting the microbiota in the host's gut-brain axis. Common psychobiotics used in research include Bifidobacterium and Lactobacillus families of gram-positive bacteria, which are less likely to cause an immunological response. Specific psychobiotics like Lactobacillus rhamnosus have been shown to lower anxiety and reduce obsessive-compulsive disorder. Probiotic foods high in beneficial bacteria include yogurt, kimchi, kefir and sauerkraut. Research suggests psychobiotics may reduce stress hormones, stimulate the vagus nerve, and increase neurotrophic factors to help treat anxiety disorders.

Nitrogen cycle.ppt
Nitrogen is a key nutrient for plants but it exists primarily as inert nitrogen gas in the atmosphere. The nitrogen cycle describes the process by which nitrogen is converted between various chemical forms as it moves between the atmosphere, soil, organisms, and various environmental reservoirs. Key steps in the nitrogen cycle include nitrogen fixation by bacteria, nitrification of ammonia to nitrites then nitrates, assimilation of nitrogen by plants and animals, ammonification of organic nitrogen waste by decomposers, and denitrification of nitrates back to nitrogen gas. The nitrogen cycle is essential for providing plants with nitrogen needed for growth while enriching soils with nutrients.
Psychobiotics
Psychobiotics refers to live bacteria that may provide mental health benefits by affecting the microbiota in the host's gut-brain axis. Common psychobiotics used in research include Bifidobacterium and Lactobacillus families of gram-positive bacteria, which are less likely to cause an immunological response. Specific psychobiotics like Lactobacillus rhamnosus have been shown to lower anxiety and reduce obsessive-compulsive disorder. Probiotic foods high in beneficial bacteria include yogurt, kimchi, kefir and sauerkraut. Research suggests psychobiotics may reduce stress hormones, stimulate the vagus nerve, and increase neurotrophic factors to help treat anxiety disorders.
Measuring RNA concentration
The document describes how to calculate the concentration of an RNA stock solution given absorbance measurements of a diluted sample. It explains that an absorbance of 1.0 at 260nm corresponds to 40 μg/mL of RNA. It then shows the calculations to determine that a diluted sample with an absorbance of 0.142 corresponds to 5.7 μg/mL, and that multiplying this by the dilution factor of 1000/40 gives a stock concentration of 142.5 μg/mL.
Burst size
The burst size experiment involved infecting 2 x 108 cells with phage at an MOI of 0.1. Unadsorbed phage were removed and infected cells were incubated for 90 minutes. 200 infective centers (ICs) were counted initially. After incubation, 150 plaques were counted, corresponding to 3 x 109 PFU/ml. The burst size was calculated as the PFUs released (3 x 109 PFU/ml) divided by the original ICs (2 x 107 ICs/ml), which is 150 PFUs/IC.
Diluting bacteriophage
A phage stock with a concentration of 2.5 x 109 PFU/ml needs to be diluted to give approximately 500 plaques on a plate. To calculate the required dilution factor, the researcher sets up an equation relating the original phage concentration, desired plaque count, and dilution factor. Solving the equation reveals the stock must be diluted 2 x 10-7 times. The document then shows example dilutions and volumes that would achieve this dilution factor.
Measuring phage titer
A series of dilutions were performed on a bacteriophage stock to determine its titer. The stock was diluted through four successive 10-fold dilutions. After plating 0.1 mL from the final dilution, 180 plaques were counted. Using the dilution factor of 1x10-8 mL and the formula that divides the number of plaques by the dilution factor, the titer of the original bacteriophage stock was calculated to be 1.8 x 1010 PFU/mL.
Ssdna calci
This document provides instructions for calculating the concentration of single-stranded DNA (ssDNA) in micrograms per milliliter (μg/mL). It explains that an optical density (OD) reading of 1 at 260nm corresponds to 33 μg/mL of ssDNA. It then works through an example calculation where M13mp18 DNA diluted 10 μL into 1000 μL has an OD of 0.125, corresponding to a concentration of 4.125 μg/mL. To determine the original stock concentration, this value is multiplied by the dilution factor of 1000 μL/10 μL, giving a concentration of 412.5 μg/mL for the M13mp18 DNA stock solution.
Calculation of ds DNA Concentration
This document summarizes the formula for calculating the concentration of double-stranded DNA (dsDNA) based on its absorption at 260nm. The formula, known as Beer's Law, states that absorption at 260nm (A260) equals the extinction coefficient at 260nm (E260) multiplied by the concentration (c) and light path length (l). For dsDNA, the extinction coefficient is 20 for a 1mg/mL solution and 1cm light path length. Two examples are provided to demonstrate calculating DNA concentration in μg/mL from a given A260 value using this formula and extinction coefficient.
Moi ii
The document describes how to calculate the multiplicity of infection (MOI) for an experiment using E. coli and bacteriophage. It shows that a 0.25 mL aliquot of E. coli culture containing 2 x 108 cells requires 0.05 mL of a bacteriophage stock with a concentration of 2 x 109 phage/mL to achieve an MOI of 0.5. The calculation involves determining the number of cells, calculating the number of phage needed based on the MOI and cell count, and then calculating the volume of stock solution required to provide that number of phage.
Multiplicity of infection
The document discusses the calculation of multiplicity of infection (moi), which is the ratio of bacteriophages to host cells at the initial stage of infection. Too high or too low of an moi can impact the infection process. The document then provides an example calculation where 0.1 mL of a phage stock containing 4 x 109 phage/mL is added to 0.5 mL of E. coli cells at 2 x 108 cells/mL. It calculates the total number of phage and cells, then divides the phage by the cells to determine the moi is 4 phage/cell.
Stock solution calculation
To prepare 300ml of 1x TAE buffer solution from a 50x stock solution, calculate the volume of stock solution needed using the formula C1V1=C2V2. Plugging in 50x for C1, 1x for C2, 300ml for V2 gives a value of 6ml for V1, the volume of 50x stock solution required. Take 6ml of the 50x TAE stock solution and dilute it with deionized water to a total volume of 300ml to obtain the desired 1x TAE buffer solution.
Transposons
Transposons are segments of DNA that can move from one location in the genome to another. There are two main types: insertion sequences (IS), which are short DNA sequences that code for transposase enzymes; and transposons, which can carry additional genes and are flanked by IS elements or inverted repeats. Transposition occurs when the transposase enzyme cuts and inserts the transposon into a new target site, sometimes duplicating flanking DNA. This movement allows transposons to generate genetic diversity and influence genome evolution over generations.
Ara operon
The L-arabinose operon contains three structural genes - araB, araA, and araD - that encode enzymes required for the metabolism of L-arabinose in E. coli. The expression of the operon is regulated by the AraC protein and the CAP-cAMP complex. In the absence of L-arabinose, AraC acts as a repressor by forming a DNA loop, while in the presence of L-arabinose, AraC binds to different DNA sites and activates transcription. CAP facilitates activation when glucose is absent. The operon is also used in protein expression systems by fusing genes of interest to the araBAD promoter.
Trp operon
The document discusses the tryptophan (trp) operon in bacteria. The trp operon contains five structural genes that encode enzymes for tryptophan biosynthesis. Expression of the structural genes is regulated by a trp promoter, operator sequence, and repressor protein. In the absence of tryptophan, the repressor cannot bind to the operator and the structural genes are transcribed. However, in the presence of tryptophan, it binds to the repressor and prevents transcription of the structural genes. The trp operon is also regulated by attenuation - a mechanism where tryptophan availability affects the formation of transcription terminator stem loops in the mRNA leader sequence.
Lac operon
The document describes the lac operon in E. coli, which regulates genes involved in lactose metabolism. The lac operon contains three structural genes - lacZ, lacY, and lacA - that are regulated by the lac repressor and catabolite activator protein (CAP). The lac repressor normally binds to the operator region and blocks transcription. In the presence of lactose, allolactose binds to the lac repressor and causes it to detach from DNA. CAP promotes transcription when glucose levels are low, allowing the cell to preferentially metabolize lactose over glucose. Together, these regulatory mechanisms ensure the lac genes are only expressed when lactose is available and glucose is not.
Classification of culture media
This document discusses the classification and preparation of culture media in microbiology. It begins by explaining the different types of nutritional requirements in microbes and aseptic techniques used in the lab. It then summarizes various forms of culture media like broths, slopes, plates and semi-solid media. Media can be classified based on agar concentration, ingredients used, and oxygen requirements of microbes. Simple and complex media types are described as well as enrichment and selective media. Special media like Robertson's meat broth and thioglycollate are used for isolating anaerobic bacteria.
Different forms of media
This document discusses different forms of culture media used in microbiology. It describes nutrient broth as a liquid culture medium used to grow fastidious microorganisms. Preparation of nutrient broth involves adding broth powder to water, mixing, pouring into containers, and autoclaving. Agar slopes are prepared by pouring molten agar into test tubes at an angle to solidify in a slanted form. Agar deeps allow observation of bacterial growth patterns in agar due to oxygen gradients. Solid and semisolid media contain varying concentrations of agar to control consistency and allow different growth applications.
Phage typing
Phage typing is a phenotypic method used to differentiate between bacterial strains using bacteriophages (viruses that infect bacteria). Certain bacteriophages can only infect specific bacterial strains. Phage typing involves growing bacterial cultures and spotting them with different bacteriophages - susceptible strains will show clearings where the bacteria have been lysed. While a complex method, phage typing has been useful for epidemiological surveillance and tracing outbreaks of pathogens like Salmonella typhimurium and Staphylococcus aureus. Improved standardization is needed to ensure reliable comparison of results between laboratories.
Production of biodegradable. plastic
The document discusses production of biodegradable plastics. It notes that over 140 million tons of plastic are consumed annually, most of which are not biodegradable. Bioplastics are a feasible alternative as they are made from renewable resources like vegetable oils and can biodegrade. Common types of bioplastics include polylactic acid, poly-3-hydroxybutyrate, and thermoplastic starch. The production process for polylactic acid and uses of bioplastics in packaging, catering, gardening, medical, and sanitary products are described.
Lytic and lysogeny
The document summarizes the lytic and lysogenic cycles of bacteriophage λ (lambda), which infects E. coli bacteria. It describes the key genes involved in each cycle and how they regulate viral replication and integration into the host chromosome. The lytic cycle results in viral assembly and lysis of the host cell, while the lysogenic cycle involves integration of the viral DNA into the host genome and replication with the host. The document outlines the complex interplay between viral and host genes that determines whether the lytic or lysogenic cycle occurs.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
