Vibrio cholerae is a comma-shaped, gram-negative bacteria that can cause cholera in humans. It has several key characteristics: it is a curved rod shape; gram-negative; and motile with a single polar flagellum. The plan is to incorporate V. cholerae's ability to produce toxins that cause watery diarrhea into fruit flies. Researchers will test if flies can act as hosts for V. cholerae in nature, as related arthropods may serve as true hosts.

Microorganisms can be beneficial or harmful. They are classified into five major groups - bacteria, viruses, protozoa, algae, and fungi. Bacteria are single-celled prokaryotes that can be beneficial, parasitic or saprophytic. Viruses are not considered living but can only replicate inside host cells. Protozoa are single-celled organisms that can cause diseases. Fungi include multicellular and unicellular organisms that reproduce via spores. Microorganisms are used in food production, medicine development, pollution reduction and nitrogen fixation in plants. However, they can also cause diseases and food poisoning in humans, animals and plants.
Archea and bacteria paragraphs
The document discusses four kingdoms of Archaea: Korarchaeota, Euryarchaeota, Crenarchaeota, and Nanoarchaeota. It also discusses several groups of bacteria, including Proteobacteria, Chlamydias, Spirochetes, Cyanobacteria, and Gram-positive bacteria. Key details provided include that Korarchaeota are only found in high temperature environments, Euryarchaeota include methanogens and halobacteria, Crenarchaeota were thought to be extremophiles but are also found in marine environments, and Nanoarchaeota are the smallest recently discovered in deep sea vents.
Evolution and Economic Importance of Bacillariophyta
Bacillariophyta, also known as diatoms, are unicellular algae that are important primary producers in both marine and freshwater environments. They have a unique cell wall made of silica and can reproduce both sexually and asexually. Diatoms form the base of the aquatic food chain and fossilized diatom deposits have been used to produce petroleum and other products. Despite their diversity, relationships between diatom taxa are still not fully understood.
Citrobacter & Edwardsiella
The document discusses two genera within the Enterobacteriaceae family: Edwardsiella and Citrobacter. It provides details on their characteristics, habitats, pathogenic species, and methods of identification. Edwardsiella is commonly found in reptile and fish guts, with E. tarda causing rare human infections related to trauma or aquatic environments. Citrobacter species are environmental and occasionally cause infections in humans, differing from E. coli in being citrate positive and lysine decarboxylase negative. Identification of specific Citrobacter species involves testing for indole production and H2S.

Emerging Diversity Within Well-known Heterotrophic Flagellates Groups Reveal...
During the last ten years, an overwhelming amount of data has been generated from culturing independent techniques to study the diversity of marine protists. These studies show a large diversity and the existence of new groups, such as for MAST (Marine Stramenopiles) or MALV (Marine Alveolates). However, a large part of these sequences has not been analysed together, and constitutes a potentially important source of information related with protists diversity and distribution. Using sequences from our studies and from GenBank and CAMERA, we have been able to define several novel clades in three important marine representative groups such are Choanoflagellates, Chrysophytes and Bicosecids. Most of the novel clades correspond to uncultured organisms. Analyzing all sequences together permits to observe this diversity, which was already presented by generally ignored. Only an important data mining work developed using GenBank allows this novel diversity hidden inside well know groups to emerge from the enormous sea of data generated.
Module 13 oral microbiology
The oral cavity contains hundreds of bacterial species that form complex biofilm communities on teeth and gums. Two key points:
1. Dental caries is caused by an ecological shift in the biofilm that allows acid-producing bacteria like Streptococcus mutans to dominate. These bacteria metabolize sugars to produce acid which demineralizes tooth enamel.
2. Periodontal disease involves a similar pathological shift in the subgingival biofilm toward anaerobic, gram-negative bacteria like Porphyromonas gingivalis. Environmental factors like sugar intake can disrupt the biofilm balance.

Similar to bacteria (vibrio cholerae)
Bacteria
Vibrio cholerae is a comma-shaped, gram-negative bacteria that can cause the acute diarrheal disease cholera in humans. It has a single, polar flagellum that allows it to move. V. cholerae typically infects the small intestine and produces a toxin that causes the severe watery diarrhea characteristic of cholera. While it usually spreads between humans, V. cholerae can also live in brackish coastal and river waters, and some research has suggested certain arthropods may act as hosts in the environment.
Vibrio cholerae
Vibrio cholerae is a Gram-negative, comma-shaped bacterium that lives naturally in brackish or saltwater. Some strains of V. cholerae cause the disease cholera when ingested in contaminated food or water. Cholera results in severe diarrhea and vomiting that can lead to rapid dehydration. The disease was first isolated in 1854 by Filippo Pacini, who observed the bacterium microscopically in samples from cholera patients. V. cholerae produces a cholera toxin that increases intestinal fluid secretion and capillary permeability, causing the profuse diarrhea and dehydration associated with cholera.

Bacteria structure
This document provides information about the structures and functions of bacterial cell envelopes including capsules, slime, fimbriae, pili, and flagella. It discusses how capsules help bacteria attach and protect against phagocytosis. Slime layers surround bacterial cells and allow adhesion while protecting against chemicals. Fimbriae and pili aid in bacterial adhesion and conjugation. Flagella provide locomotion and allow bacteria to sense chemicals and exhibit chemotaxis. Bacteria are classified based on flagella placement including atrichous, monotrichous, lophotrichous, ampitrichous, and peritrichous types.

Vibrio cholerae PPT for students
Cholera is a serious bacterial disease that usually
causes severe diarrhea and dehydration. The disease is typically spread through contaminated water.
Modern sewage and water treatment have effectively eliminated cholera in most countries. It’s still a problem in countries like Asia, America and Africa. Mostly in India.
Countries affected by war, poverty, and natural disasters have the greatest risk for a cholera outbreak.

Different Types of Bacteria
Bacteria can be classified in several ways:
1. Based on their morphology, bacteria are grouped as cocci, bacilli, spirilla, etc. depending on whether they are spherical, rod-shaped, spiral-shaped.
2. Bacteria are also classified based on their metabolic activities - whether they require oxygen (aerobic), do not require oxygen (anaerobic), or can survive in extreme conditions.
3. DNA sequencing and cell structure such as cell wall contents, presence of flagella, and formation of endospores are other factors used to classify bacteria into different phyla and groups.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4

TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptx
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.

Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.
Anti-Universe And Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid
