Proteobacteria

inflammatory bowel diseases such as CD and ulcerative colitis (UC). To test this hypothesis, biopsies of patients with CD and UC were obtained and compared to healthy individuals. Results indicated that individuals with CD had increased levels of the Proteobacteria and Bacteriodetes phyla but decreased levels in Firmicutes in comparison to the healthy individuals. Table 1 illustrates the precise numbers of colonies. Patients suffering from CD have shown using fluorescent in situ hybridization…

2.3 Dissimilitary nitrate reduction According to Croal et al., (2004), bacteria such as Shewanella oneidensis can reduce Nitrate (NO3-) for the purpose of assimilation and in this research is consider only those that engage in dissimilatory nitrate reduction Ammonium (DNRA). Which is the process of using (NO3-) as a terminal electron acceptor in anaerobic respiration. (NO3-)-reducing bacteria is mainly have habitat in freshwater and marine environments. They play significantly affect in the…

Bacteria also known as prokaryotes are very ancient single-celled organisms; fossils show that they were widespread 1.5 billion years ago. Today bacteria make up the vast majority of prokaryotes on earth due to the unfavorable ability to adapt quickly to the surrounding environment. Bacteria have the capabilities to survive in areas of high heat, extreme cold, or even very acidic or alkaline conditions. This ability is used frequently to fend off the effects of antibiotics and antibacterial;…

Van Tran Microbiology Tuesday 5:00 May 5, 2015 Unknown Sample # 7 1. Introduction: Using biochemical tests are a good way to identify unknown bacteria from a sample. It is basically a similar to a trial and error method, but rather than using trial and error a person would be using positive and negative results. Using biochemical tests will help a person identify certain characteristics of the unknown bacteria through a series of chemical tests. Of course more than one biochemical tests…

Prokaryotic cells include bacteria that includes pathogenic and nonpathogenic prokaryotes that can be found in soil or water. The six types of bacteria include Proteobacteria, they are gram negative and are the largest classification of all of the bacterias. Proteobacteria has five classes which are alpha, beta, gamma and delta. The next classification is Cyanobacterias which has some oxygenic photosynthetic bacteria. All of them are gram negative and they like to…

in humans and other animals. It is a unicellular micro-organism, making its Domain and Kingdom Bacteria. E. coli’s Phylum is Proteobacteria because it is a gram-negative bacterium. It is also in the Phylum Proteobacteria because of the lipopolysaccharides that protect the cell membrane. E. coli is a facultative anaerobic G- bacterium, making its Class Gamma Proteobacteria. Because of its rod-shape, E. coli’s Order is Enterobacteriales. Escherichia coli has peritrichous flagella, meaning the…

This would include the microorganism causing it known as Bartonella henselae and how it is an aerobic, intracellular, proteobacteria. As well as how this bacteria makes its way into a cats system through ticks and fleas, and into our bodies through scratches, bites, or saliva. Once B. henselae makes its way into our system it will adhere to the erythrocytes and replicate until…

through the chambers into the isolated soil sample allowing the isolated uncultured bacteria to grow. After a colony was produced it was screened for antimicrobial activity on plates containing S. aureus. The screening research found that a beta-proteobacteria named Eleftheria terrae showed good activity. However, 16S rDNA and in silico DNA/DNA hybridization showed the researchers that the organism was related to the known genus Aquabacteria, a Gram-negative organism which is not an antibiotic…

This article targets the increased interest of how microbial communities and the environment affect one another through impacting the evolutionary features of the organisms they interact with. Shifts within the environment can consist of predictable and unpredictable changes. Predictable changes are consistent shifts in the surrounding environment that occur daily or seasonally. Animals and plants developed the use of external cues that regulate this when predictable changes in their environment…

less conserved in not closely related species. The last hypothesis for this study is that the promoter regions of ctrA is more conserved in closely related species and less conserved in not closely related species. All sequenced genomes of alpha proteobacteria contain ctrA genes. CtrA regulates numerous events in the cell cycle. The metabolism and division of the cell wall, stalk synthesis, polar…
