E.Coli (Escherichia Coli ) Brenda Arambula Health Science Technology 3/4/2016 INTRODUCTION Escherichia Coli most known as (E.Coli) is a bacteria that normally gets into your intestine of humans and sometimes even warm blooded animals .Some of the E.Coli are even capable of causing diseases with conditions that can harm your immune system . E. Coli can make everyone sick but it mostly affects young children and elderly people this people are mostly likely to develop severe health problems , Some children or infant can even get hemolytic uremic syndrome (HUS) this is like anemia that hits the children with . There 's so many things that make you get E coli eating raw vegetable or raw meat basically if you eat anything that is raw you 're going to get the bacteria . If you 're a healthy adult you can recover in within a week but if you 're not that healthy it can take you more than a week for you to get rid of the bacteria . PATHOPHYSIOLOGY E. Coli is a bacteria that can cause a rise if you have a infection , wounds ,urinary tract etc.. E. Coli infections can happen due to environmental exposure . Infections…

crescentus is just one bacteria belonging to an extremely diverse phylum known as Proteobacteria. Not only has the ctrA gene been found to be essential in C. crescentus, it has also been found quite necessary for viability in three other bacterium: Sinorhizobium meliloti, Agrobacterium tumefaciens, and Brucella abortus (Greene et al.,2012). In addition to the three bacterium previously stated, research has also supported that ctrA plays a critical role in the regulation of motility amongst…

hypothesis. The syntrophic hypothesis is comprised of a delta proteobacteria, which were ancestral sulphate reducing myxobacteria and was considered the host. The delta proteobacteria hosted a methanogenic archaea symbiont. The delta proteobacteria were responsible for reducing sulphates. The archaea fed off of the byproducts of the proteobacteria, which were hydrogen and the carbon dioxide (2). Syntrophy is the dependence of each species on one another for nutritional requirements and is the…

under the stereomicroscope, seen in Figure 2.2, the colony’s form appear circular, its elevation is convex, and the margins are even/entire. The colony was put under UV illumination to look for fluorescent. Fluorescents is usually seen in Pseudomans fluroescens and it appears green under UV illumination. When the isolated colony was put under UV illumination, it was not fluorescent and appeared green. This showed that Pseudomans fluroescens was not present in the sample. B. Gram Stain Gram…

bacteria in the human’s colon produce vitamins K and B12. Bacteria produce antibiotics which protect animals from pathogens and scientists have genetically engineered bacteria to produce hormones like insulin and human growth hormone. Prokaryotes are even vital to commerce. Bacteria are necessary to create food products like cheese, yogurt, soy sauce, and chocolate. Make a chart of the six important types of bacteria and their key features. Group Characteristics Photosynthetic (undergo a…

Microbiota are microscopic organisms such as viruses, bacteria, archaea, and eukaryotes that influence human health through a commensal interaction. Location of microbiota can be internal or external such as the gut, mouth, placenta, skin, and vagina. These microbes are classified into four major phyla: Firmicutes, Bacteriodetes, Actinobacteria, and Proteobacteria. Microorganisms in the Firmicute phylum are typically Gram positive bacteria, either rod-shaped or spherical and function as obligate…

polyploidic cocci, lacking flagella and motility and resistance to hydrogen peroxide and other agents that damage DNA because of a highly efficient DNA repair system. Although they are considered Gram-positive, they may be an intermediate between gram-positive and gram-negative bacteria and form a distinct bacterial lineage of extremophiles; the Firmicutes phylum has a diversity of microbes associated with the human gastrointestinal tract, especially with fatty acids absorption which makes it…

Next, a new class of natural antimicrobial agent, teixobactin is recently found as a strong bactericidal agent which is active against MRSA treatment. Teixobactin is produced by Eleftheria terrae, a new species of β-proteobacteria which belongs to a new a new genus related to Aquabacteria. Teixobactin is a depsipeptide which contains compounds such as enduracidin, methylphenylalanine and four D-amino acids that involves in inhibiting the synthesis of peptidoglycan. According to Ling et al’s…

Kayla Southworth Professor Borgeson Bio 251 December 4, 2015 Helicobacter pylori Helicobacter pylori is a microbe that comes from the kingdom bacteria, under the domain of Eubacteria, where its phylum is the proteobacteria. While Helicobacteria pylori is in the wide phylum of Proteobacteria it is grouped under the order of Epsilonproteobacteria under its subset of Campylobacterales. When Helicobacter pylori go under the performance of a gram stain it comes out…

For example, recently, it has been shown that epigenetic modifications in the closely related gamma-proteobacteria, Salmonella enterica, can regulate the transition from planktonic to biofilm growth, and that this transition is caused by changes in gene expression induced by epigenetics.27 Additionally, it has been demonstrated that an epigenetic switch in H. influenzae can control virulence and the transition to biofilm growth.28 Epigenetic mechanisms such as DNA methylation are now understood…
