Escherichia coli

USDA, ‘irradiate’ the meat instead of cleaning the factories. Irradiation is meat being subjected to gamma rays, which do not kill the microorganisms, but instead change the DNA. Escherichia coli, E. coli, is considered a main issue. Americans in 2006 panicked; when spinach from California was found to contain E. coli, killing an elderly lady and sickened many others. It was later found that the spinach itself…

Introduction Moro et al., 2000 described an increased antimicrobial drug resistance of Escherichia coli in the intestinal flora of swine as a response to heat stress. This observation was gathered over the course of four studies. Throughout the four studies, finisher pigs (85 kg) were utilized from a common source of swine which had not been supplemented fed antimicrobials for the previous ten years. Animals were randomly selected from a single pen and transported to the research facility 30d…

four broth cultures: Escherichia coli, Enterobacter aerogenes, Staphylococcus epidermidis, and Streptococcus faecalis showed observable growth when applied. The different medias will either promote or inhibit the growth of the organisms allowing their isolation to be possible (Lengeler and Schlegel, 1999). These four types of organisms will react accordingly based on their preferable environmental conditions. Observing their growth…

Acinetobacter baumannii is a gram negative coccobacilli bacteria. It is an aerobic Glucose non-fermentative and oxidase negative. This bacterium is able to avoid desiccation for more than 30 days. It can be Opportunistic pathogen in human and It is commonly isolated from the hospital environment and hospitalized patients causing nosocomial infection [1]. This bacterium is responsible for causing several diseases in human such as pneumonia, urinary tract infection, Meningitis, wound infection,…

Abstract: The objective of these series of experiments was to identify two unknown bacteria’s. Broth culture #20 was selected and subjected to qualitative tests for identification. Gram stain tests were performed in order to identify which unknown is gram positive and gram negative. Using selective and differential media, like MacConkey agar which allows the growth of gram negative bacteria only that are able to ferment lactose. Also, mannitol agar was used which isolates and detects…

Microbiology in itself is such a vital field which contributes and continuously defines the world in which we live in. Charles Darwin once stated “Each living creature must be looked at as a microcosm--a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven” (Goodreads, 2015). I really liked this quote because I think it explains the vastness that microbiology possesses. We tend to look at the world seeing one individual…

Injection on Prokaryotic Gene Expression. By Kush Patel 3rd Period, AP Biology, February 12, 2024. Lab Partners: What is the difference? Brody Bonsor Andrew Zhang Marianne Baquero Clarie Gabrielson Abstract: In the pGLO lab, E. coli bacteria were genetically modified using a plasmid that contained three key genes: araC, GFP, and ampicillin resistance. Through a process of heat shock and incubation, the pGLO plasmid was successfully introduced into the bacteria. This allowed…

Purpose: The purpose of this lab was to compare the effect of using soap (antibacterial and non-antibacterial) and no soap on the growth of Escherichia coli (E.Coli). Hypothesis: If anti-bacterial and non-antibacterial soaps are added to a standard agar media before the E.Coli was introduced and incubated, then the portion of the plate containing the antibacterial soap will have the least amount of bacterial growth because the antibacterial soap contains a higher percentage of bacteria-killing…

infection that ascended to the pelvis of the kidney. Severe cases of pyelonephritis can cause systemic sepsis, pyonephrosis, renal failure, multisystem failure and death. In most cases, the infection is caused by gram-negative bacteria, mostly Escherichia coli, which is transmitted from anal and perianal…

my clinical rotation at Palmetto Richland on the Acute Care for the Elderly unit there were several patients on contact precautions due primarily to Methicillin-resistant Staphylococcus aureus (MRSA) or high counts of gram-positive Escherichia coli bacterium (E. coli) in the urine and blood. A good example of best practice that I witnessed was the proper display and implementation of contact precautions around patients with multidrug-resistant organisms and bacteria (MDROs). If a patient is…
