Proteobacteria

Campylobacter: I am a Gram-negative bacteria, I belong to the Phylum of Proteobacteria. The class I belong to is Epsilonproteobacteria respectively. I have almost 30 species. Interviewer: But doesn’t it gets difficult to differentiate between all of you considering that you all being to the genus Campylobacter? Campylobacter: Well you are right. But each one of us has a different surname. Well you see mine is “Campylobacter Jejuni.” Interviewer: Wow! That’s a difficult one. Now please tell us what

Lowest effective concentration of bleach analysis lab Problem Statement: What is the lowest concentration of bleach that can effectively kill E.coli bacteria? Hypothesis: The lowest concentration of bleach that effectively kills E.coli bacteria is 0.1%. Background information:  Bleach, a solution made from sodium hypochlorite and water, is a chemical used as a household cleaner. It is effective in killing bacteria and other microorganisms because when sodium hypochlorite comes in contact with viruses

Characteristics of Neisseria Gonorrhea There are many types of pathogens classified as sexually transmitted infections such as chlamydia, genital herpes, HIV/AIDS, and gonorrhea. These pathogens are generally spread by sexual contact. The bacterium Neisseria Gonorrhea is a well-known pathogen or STI that can quickly populate and mutate. In order to better understand how this type of bacteria can be spread, we must first understand its general characteristics, pathogenic factors, means of transmission

Introduction: Background Information: E. coli or Escherichia coli is a prokaryotic cell found the in lower digestive track of mammals and other warm blooded animals. E. coli is an easy bacteria to work with as it doubles quickly and is relatively easy to grow, millions of cells can be grown in several hours. E. coli is an ideal bacteria in the lab because it does not require its temperature to be too hot, too cold, or too precise. A general warm temperature is perfect for this bacteria. E. coli is

Introduction Escherichia Coli, located in one of the main organs known as the large intestine, is a type of bacteria that helps digestion. (Trzepacz, Timmons, and Duobinis-Gray, 2016) For Escherichia Coli to remain stable and alive, it needs specific necessities. These needs are known as the following: Energy, vitamins, and similar compounds. Escherichia Coli is found everywhere! Escherichia Coli, or E. Coli, can also form a number of these substances itself with the use of energy. (Shiloach

Escherichia coli, or E. coli, is a common bacterium that can be found in diverse environments all over the planet, including the gastrointestinal tracts of animals and humans. Many of these strains of E. Coli are essential mechanisms in the digestive tract, while others are pathogens that can cause complications in urinary and intestinal tracts. (Payne & Sparks) In research, E. Coli is commonly used as a model organism, meaning they are widely studied by scientists for a variety of purposes due to

Once it was reported that the outbreak was linked to Jack in the Box and Foodmaker, the corporation acted to deal with the situation. First, by the 19th of January 1993, Jack in the Box had replaced 280,000 hamburger patties (“Meat seized in poisoning,” 1993), retrained all employees regarding the handling of meat products, and raised the cooking temperature in Jack in the Box restaurants to the state standard of 155 degrees (Littlefield, 2005). Even though at first, they did not want to “comment”

may pass on specific bacterial species. (2) Two transient bacteria found on the SML were Bacteroidetes sp. and Sphingobacterium sp., which also exist in the water column. A predominant surface that is associated with microbial bacteria is alpha proteobacteria, which is present in both the water column and SML. It appears to be a common bacteria amongst many corals as it is mentioned to be found in both colonies of A. millepora and A. hyacinthus on Heron island. (3) Other bacteria found specific to

Introduction: Metazoan body contains trillions of bacteria which live in symbiotic relationship with their host (Human Microbiome Project, 2012). Microbiota plays a crucial role in numerous metabolic processes such as digestion, immunity, nutrient metabolism. Microbial community present in a particular niche or organ has a specific functional capacity which contributes to survival and fitness of host (Costello et. al., 2009; Turnbaugh et. al., 2009a). Disturbances in microbial community relate to

The 16S rRNA gene sequences amplified from cranberry bogs resolved into 49 bacterial phyla. The overall bacterial composition of the different samples was similar, particularly among the six most highly-represented groups (Fig. 1). Proteobacteria, Acidobacteria, Bacteroidetes, and Verrucomicrobia were the most dominant phyla (relative abundance > 5 %) in every sample, together accounting for about 78 % of the bacterial sequences in the soils examined. The Actinobacteria and Chloroflexi were also
