Apvs2013 09 vosloo et al.-o1 manisa efficacy vs viet fmd strain in pig
This study tested the efficacy of an O1 Manisa high potency vaccine against challenge with the O/Vietnam/2010 strain in pigs. Pigs were vaccinated 4 and 7 days prior to challenge. Most vaccinated pigs were protected from clinical disease at both timepoints. Virus RNA was detected in nasal secretions of vaccinated pigs for shorter durations than in unvaccinated controls. Vaccinated pigs shed insufficient virus to infect direct contact pigs. The vaccine decreased virus excretion and transmission, suggesting it could help control disease outbreaks when used with biosecurity measures.

Self-protection from malaria vectors in Pakistan
Experimental huts were used to test several self-protection techniques against malaria vectors in Pakistan. Permethrin-impregnated curtains provided the highest protection, reducing blood-fed Anopheles stephensi by 65%. Pyrethroid-vaporizing mats and untreated curtains also significantly reduced vector populations. All techniques mainly worked by reducing mosquito entry into huts, but also decreased blood-feeding rates. While various strategies offered some benefit, impregnated curtains and bednets seem most promising if social and economic barriers can be addressed and use encouraged throughout risk periods.

Tuberculosis in India
In India, each year, approx. 220,000 deaths are reported due to Tuberculosis. Between 2006 and 2014, the disease cost Indian economy USD 340 billion. This public health problem is the world's largest tuberculosis epidemic. India bears a disproportionately large burden of the world's tuberculosis rates, as it continues to be the biggest health problem in India. Wikipedia

Limitations in the screening of potentially anti-cryptosporidial agents using...UniversitasGadjahMada
The emergence of cryptosporidiosis, a zoonotic disease of the gastrointestinal and respiratory tract caused by Cryptosporidium Tyzzer, 1907, triggered numerous screening studies of various compounds for potential anti-cryptosporidial activity, the majority of which proved ineffective. Extracts of Indonesian plants, Piper betle and Diospyros sumatrana, were tested for potential anticryptosporidial activity using Mastomys coucha (Smith), experimentally inoculated with Cryptosporidium proliferans Kváč, Havrdová, Hlásková, Daňková, Kanděra, Ježková, Vítovec, Sak, Ortega, Xiao, Modrý, Chelladurai, Prantlová et McEvoy, 2016. None of the plant extracts tested showed significant activity against cryptosporidia; however, the results indicate that the following issues should be addressed in similar experimental studies. The monitoring of oocyst shedding during the entire experimental trial, supplemented with histological examination of affected gastric tissue at the time of treatment termination, revealed that similar studies are generally unreliable if evaluations of drug efficacy are based exclusively on oocyst shedding. Moreover, the reduction of oocyst shedding did not guarantee the eradication of cryptosporidia in treated individuals. For treatment trials performed on experimentally inoculated laboratory rodents, only animals in the advanced phase of cryptosporidiosis should be used for the correct interpretation of pathological alterations observed in affected tissue. All the solvents used (methanol, methanol-tetrahydrofuran and dimethylsulfoxid) were shown to be suitable for these studies, i.e. they did not exhibit negative effects on the subjects. The halofuginone lactate, routinely administered in intestinal cryptosporidiosis in calves, was shown to be ineffective against gastric cryptosporidiosis in mice caused by C. proliferans. In contrast, the control application of extract Arabidopsis thaliana, from which we had expected a neutral effect, turned out to have some positive impact on affected gastric tissue.Antiviral Effects of Beta Lactoglobulin against Avian Influenza Virus
Introduction The avian virus is an Influenza A virus that spread widely among human through direct or indirect contact with infected birds or poultry. But a totally new pandemic of avian virus those are becoming resistant to drugs by changing their genomes may be prevented by antiviral medicines and vaccines. Objective For this purpose ß lactoglobulin is esterified with various alcohols over different circumstances like acidity, protein intentness, water substance, time, temperature, etc. Methodology Methylated ß lactoglobulin provides antiviral activities against human flu infection subtype H3N2, subtype H1N1, and subtype H5N1. The impact of this study is viral HA Hemagglutinin action is repressed by the imposition of different convergences of MET BLG depending upon their distinctive concentration. Result A large number of positive charges on the MET BLG can disrupt the electrostatic intuitive inside hem agglutinin subunits that influences its soundness and movement, lessens its capacity to intertwine and restraints its contamination power. But HA is not the unique factor that decides the viral virulence and infectivity of the virus. Conclusion A different result shows that a higher incubation time increases the antiviral activity of MET BLG.

Remdesivir and chloroquine were found to be highly effective at inhibiting the novel coronavirus (2019-nCoV) in vitro. Remdesivir had an EC50 of 0.77 μM and chloroquine had an EC50 of 1.13 μM, both showing potent antiviral activity at low micromolar concentrations. Time-of-addition experiments demonstrated that remdesivir and chloroquine functioned at stages post viral entry. Given their proven safety profiles in humans and effectiveness against other viruses, the authors suggest that remdesivir and chloroquine should be assessed for treating patients infected with 2019-nCoV.
Scientists data for covid 19 .
Scientists have found evidence that the coronavirus may be mutating and adapting to humans. Analysis of over 5,300 coronavirus genomes from around the world showed that some strains have gained mutations in the spike protein that the virus uses to infect cells. While the mutations are still rare, they arose independently in different countries and may help the virus spread more easily. Scientists are concerned that more extensive mutations could impact the effectiveness of potential vaccines and treatments being developed that target the spike protein. Ongoing surveillance is needed to monitor any changes in the virus.

Trypanosomosis has been associated with immunosuppression, anemia and oxidative damage while ImmuneAce and Iron Dextran
possess both immunostimulatory, antioxidative and erythrocytes enrichment effects. This study was designed to assess the effect
ofImmunace, Iron Dextran, Diminazene Aceturate and a combination of Immunace and Iron Dextran on T. brucei experimentally
infected rats to check packed cell volume (PCV) and parasitemiam. . Thirty rats, divided into six groups (A-F) of 5 each period and
were infected with Trypanosoma brucei 3 days post infection.They were treated as follows:3, 6, 9, 12 and 15 days post treatment
with 0.02gml-1 immunace, 0.2ml of Iron Dextran, 3.5mg Kg-1 of Diminazene Aceturate and a combination therapy of Iron Dextran
and Immuneace. Haematological parametres were significantly (p<0.05) higher in all infected and treated groups compared to
group E. Hence, overall anti-oxidants capacity mitigated the negative effects observed in the measured parametres in rats better
than single administration..

• Some of the tested drugs (NSAIDs including aspirin, diclofenac, meloxicam & flunixin meglumine) possess broad-spectrum antimicrobial activity but not in therapeutically achievable non-toxic concentrations in the body. Paracetamol was the least effective as antimicrobial similar to pheniramine maleate.
• A few of the NSAIDs may be evaluated as topical use antimicrobials (aspirin, diclofenac & flunixin) being microbial growth inhibitors at 0.128% concentration, similar levels of antimicrobial drugs including antibiotics are often used in topical antiseptic preparations (gels/ ointments/creams/powders/ lotions).
• Studies should be conducted on synergism/ antagonism of NSAIDs with commonly used antibiotics and herbal antimicrobials so that antimicrobial potential of NSAIDs can be therapeutically utilized.
• Susceptibility of bacteria to NSAIDs may be an aid in the differentiation of a few bacteria like Klebsiella and Raoultella; Enterococcus and Streptococcus (meloxicam); Bacillus and Paenibacillus (Diclofenac). However, multicentric studies on a greater number of strains are essential to establish the difference.

This article discusses using drugs that target host proteins, rather than HIV proteins, to prevent HIV transmission. It focuses on farnesyl thiosalicylic acid (FTS), a Ras inhibitor currently in cancer trials. FTS blocks a signaling cascade required for HIV entry into cells. The article reviews data on FTS' potential as a topical microbicide to prevent sexual HIV transmission. While FTS did not meet microbicide screening criteria, the authors suggest its combination with other antiretrovirals may be worth exploring for pre-exposure prophylaxis. Developing drugs targeting host proteins in addition to CD4, CCR5 and CXCR4 could lead to novel antiviral therapies and microbicides

Human cognition and perception involve receiving sensory input, processing and storing information, and applying knowledge. The key points are:
- Humans receive visual, auditory, haptic, and movement information which is stored in sensory, short-term, and long-term memory.
- Vision involves light being focused on the retina and processed by the brain to interpret size, depth, brightness, color, and detect patterns and movement.
- Hearing provides information through the ear receiving sound waves which are transmitted as electrical signals to the brain.
- Memory includes sensory memory, short-term memory for temporary recall, and long-term memory for storing knowledge which can be retrieved through recall and recognition.

MRSA
This study analyzed 200 pus samples to determine the incidence of methicillin-resistant Staphylococcus aureus (MRSA) and associated risk factors. 80 samples were found to contain S. aureus, of which 29 tested positive for the mecA gene, confirming MRSA. Testing methods like cefoxitin disk diffusion and oxacillin screen agar were compared to the PCR gold standard. The cefoxitin test showed 96.55% sensitivity and 96.22% specificity for detecting MRSA, outperforming oxacillin tests. Risk factors like hospital acquisition, diabetes, and sex were also analyzed. The study concludes that cefoxitin testing is an effective alternative to PCR for MRSA detection
Fighting malaria
This document discusses using paratransgenesis to combat malaria. It describes engineering the symbiotic bacteria Pantoea agglomerans from mosquito midguts to secrete proteins that kill Plasmodium parasites. Experiments show the engineered bacteria proliferate in mosquitoes, efficiently secrete anti-Plasmodium proteins, and reduce parasite levels in mosquitoes by 68-84% without impacting mosquito lifespan. The document concludes that using P. agglomerans to deliver multiple antimalarial proteins is an effective and resistance-proof strategy to block malaria transmission.
Clinical Manifestations of Plasmodium bergheiANKA Infection in Juvenile Mice:...
Malaria is an important health and development challenge in Africa, Animalmodels most particularly mice, have long been employedto study malaria pathogenesis. Clinical manifestations due to Plasmodium bergheiANKA infection in juvenile mice as a model for understanding the complications ofcongenital malaria in neonates.Forty-five juvenile mice (5-7 days old) were acquired from University College Hospital, Ibadan and injected with 2 x 107 (0.2ml) Plasmodium berghei ANKA parasitized red blood cells (PRBCs). Mice were transported to the study site, kept in well ventilated cages and fed daily with a balanced ration. Every day after post-P. berghei infection, mice were monitored for mortality. Clinical manifestations ofexperimental cerebral malaria (ECM) was assessed and confirmed if at leastruffled fur, hunching, wobbly gait, limb paralysis, convulsions, or coma was observed. Each sign was given a score of 1. Animals with scores ≥4 were considered to have severe ECM.20 (44%) micewerelost due to natural cause (i.e. stress) at day 2 of the experiment. Between day 4 and 9, 25 (56%) of the studymice presented clinical signs of ECM which includes; ruffled fur 25(100%), hunching 21 (84%), wobbly gait 17 (68%), limb paralysis 20 (80%), convulsions 25 (100%) and subsequently died. Survival rate and severity of ECM in the mice differs, 22 (88.0%) had severe ECM and 3(12.0%) had mild ECM.This study has shown that parasite establishment and malaria complications can manifest as early as 4 days’postP. berghei infection in 5-7 days old mice.
Leishmania amazonensis INFECTION INDUCES CHANGES IN POTASSIUM PERMEABILITY OF...
1. The document examines how Leishmania amazonensis infection affects the membrane potential and potassium permeability of macrophage-like cells.
2. It finds that infected macrophages initially depolarize but then hyperpolarize over time as infection progresses, shifting their membrane potential. This hyperpolarization is accompanied by an increase in inward potassium currents.
3. The changes are specific to infection by the parasite and differ from those seen due to phagocytosis of latex beads. The hyperpolarization and increased inward currents during later infection suggest the parasite modifies ion transport properties of macrophages to benefit its survival.
Marios Stylianou_Paper II_ Novel High-Throughput Screening Method for Identif...
This document describes the development of a new high-throughput screening method to identify inhibitors of the yeast-to-hypha morphological transition in the fungal pathogen Candida albicans. The method uses automated microscopy and image analysis to quantitatively measure morphological parameters that distinguish between yeast and hyphal forms. Parameters like length/width ratio and mean object shape are calculated from images of fluorescently stained cells. Cell viability is also measured to identify inhibitors that block morphological transition without affecting growth. The method is validated using known inhibitors like farnesol and shown to be suitable for high-throughput screening through calculation of the Z-factor metric. This screening method could help identify new antifungal drug candidates that target virulence traits rather

Antioxidants are substances which are capable to protect the body from damages caused by free radical. A variety of free radical scavenging antioxidants exists in the body and many of them are derived from plant sources. The aim of the present study was to investigate the antioxidant activity of the absolute ethanolic extract of Enantia chlorantha stem bark on typhoid fever induced rats. Salmonella typhi infected rats were treated every day between 7 to 9 AM with different doses of plant extract (9.16, 36.5 and 73 mg/kg or oxytetracyclin 20 mg/ kg). After 09 days of treatment, the results show that the different doses of this extract have all contributed to the cure of the infected rats, healing marked by the absence of salmonella in animal’s blood cultured on ss agar. In the other hand, treatment with different doses of plant extract result in a relative and signifi cant (p < 0.05) increase in the level of some blood and tissues antioxidant parameters such as CAT, SOD and POD while the level of alkaline phosphatase, malondialdehyde and nitric oxide as compared to untreated control group animal as compared to the untreated control group animals. Whereas, the level of ALP, MDA and NO were signifi cantly decreased (p < 0.05). These results showed that the absolute ethanolic extract of E. chlorantha stem bark possess antioxidant and antityphoid properties necessary to eradicate the free radical produced during typhoid fever infection.

The study assessed the risk of resistance developing in the oomycete fungus Pseudoperonospora cubensis, which causes cucumber downy mildew, to the fungicide flumorph. Researchers compared flumorph to dimethomorph and azoxystrobin in terms of the ease of isolating resistant mutants, the level of resistance induced, and the fitness of resistant mutants. Attempts to induce resistance to flumorph and dimethomorph by adapting sporangia on treated leaves were unsuccessful. Moderately resistant mutants were isolated using UV mutagenesis for flumorph and dimethomorph, but resistance levels were much lower than for azoxystrobin-resistant mutants.
Univ candida PCR Primer
This document describes a study that developed a one-enzyme PCR-RFLP assay to identify six medically important Candida species using the ITS1-5.8S-ITS2 regions of fungal rRNA genes. The researchers amplified this region from standard strains using universal primers and digested the PCR products with the restriction enzyme Msp I. This allowed discrimination of C. albicans, C. glabrata, C. parapsilosis, C. tropicalis, C. krusei, and C. guilliermondii based on differences in fragment sizes. The method was then used to identify 137 clinical Candida isolates, correctly identifying C. albicans as the most

1) The study examined the impacts of pesticides used in corn fields in Quebec on honeybee colonies. Experiments showed higher honeybee mortality and weaker hives in fields with moderate-to-high pesticide usage compared to low usage or control fields.
2) Laboratory analysis found that honeybees exposed to pesticides had increased levels of the enzyme acetylcholinesterase, indicating exposure. Biomarkers are being developed to better evaluate pesticide impacts on honeybee health.
3) Ongoing work includes measuring vitamin A and immune system enzymes in honeybees to study how pesticides may weaken immunity and facilitate viral infections.
Effect of Cage-Wash Temperature on the Removal of Infectious Agents
Laboratory animal cage washing has traditionally employed very hot rinse or wash water to assure the destruction of microbial agents which can cause disease in laboratory animals. This study shows an alternative that may conserve substantial amounts of energy and still provide suitable results.

This study investigated the prevalence of Toxoplasma gondii infection in 197 pets and stray cats in 4 districts of Khyber Pakhtunkhwa, Pakistan using serological (ELISA) and molecular (PCR) techniques. The results showed that T. gondii infection was significantly higher in stray cats (74.6%) compared to pet cats (25.4%). Infection rates also varied significantly between districts and were highest in Kohat (95.5%). Older cats (>4 years) had significantly higher infection rates (91.66%) than younger cats. Chronic and reactivated chronic infections (58.37%) were more common than acute infections. This research suggests T. gondii is widely
Avian Influenza History
The document summarizes experiments evaluating the efficacy of an inactivated H5N2 avian influenza vaccine against H5N1 challenge viruses. Experiment 1 found the vaccine reduced deaths and shedding in chickens challenged with H5N1 when given a single dose. Experiment 2 found a booster dose further reduced deaths and shedding against a higher H5N1 challenge dose. Experiment 3 showed no deaths or shedding when vaccinated chickens were exposed to H5N1-infected birds. However, the vaccine did not fully prevent virus shedding, transmission, or protect against high H5N1 challenge doses. The conclusion questioned if this was due to genetic differences between the vaccine and challenge viruses.

1. The study evaluated the effectiveness of different oseltamivir prophylaxis regimens in preventing influenza virus infection and transmission in a ferret model of household contact exposed to influenza A(H1N1)pdm09.
2. Contact ferrets receiving oseltamivir prophylaxis twice daily showed better outcomes than those receiving it once daily, including a significant delay in secondary infection, lower weight loss, and higher activity levels.
3. Neither prophylaxis nor treatment prevented infection or reduced viral shedding duration, although clinical symptoms improved in infected animals receiving prophylaxis. Oseltamivir prophylaxis failed to reduce viral titers, warranting further investigation in humans.

Abstract Background A refugee shelter that is treated with insecticide during manufacture would be useful for malaria control at the acute stage of an emergency, when logistic problems, poor co-ordination and insecurity limit the options for malaria control. Methods Tents made of untreated canvas with deltamethrin-treated polyethylene threads interwoven through the canvas during manufacture, 'pre- treated tents', were tested in Pakistan for their impact on malaria vectors. Fixed-time contact bioassays tested the insecticidal activity of the material over 3 months of outdoor weathering. Unweathered tents were erected under large trap-nets on outdoor platforms and tested using wild-caught, host-seeking mosquitoes and insectary-reared mosquitoes released during the night into the trap-nets. Results The insecticide-treated tents were effective both in killing mosquitoes and reducing blood-feeding. Mean 24 hour mortality was 25.7% on untreated tents and 50.8% on treated tents (P = 0.001) in wild anophelines and 5.2% on untreated tents and 80.9% on treated tents (P < 0.001) in insectary-reared Anopheles stephensi. Blood-feeding of wild anophelines was reduced from 46% in the presence of an untreated tent to 9.2% (P < 0.001) in the presence of treated tents and from 51.1% to 22.2% (P < 0.001) for insectary-reared An. stephensi. In contact bioassays on tents weathered for three months there was 91.3% mortality after 10-minute exposure and a 24 h holding period and 83.0% mortality after 3-minute exposure and a 24 h holding period. Conclusion The results demonstrate the potential of these pre-treated canvas-polyethylene tents for malaria control. Further information on the persistence of the insecticide over an extended period of weathering should be gathered. Because the epidemiological evidence for the effectiveness of pyrethroid-treated tents for malaria control already exists, this technology could be readily adopted as an option for malaria control in refugee camps, provided the insecticidal effect is shown to be sufficiently persistent.
