Additionally, Mariana’s faeces sample result were clear of any bacteria growth especially Salmonella and E.coli. Several species of microorganism such as…
Escherichia coli DH5훂 is the third species being studied. Since E. coli bacteria are considered model organisms, they make perfect study subjects. This particular strain of E. coli is not considered a pathogen. It was made especially for laboratory study. It’s main use has been mostly for cloning.…
Investigating Enterococcus faecalis’s structures and resistances to antibiotics Introduction Bacteria’s phenotype is commonly described as gram-negative or gram-positive from conducting a gram stain. A bacterium that is gram-negative tends to have cells composed of a thin peptidoglycan layer, and a gram stain of gram-negative bacteria are seen as red or pink through a microscope (Smith and Hussey, 2005). On the other hand, a bacterium that is gram-positive will have cells made of a thick peptidoglycan layer, and the gram stain of a gram negative bacteria would be seen blue or purple (Smith and Hussey, 2005). In particular, Enterococcus faecalis is a gram-positive bacterium which has been found in many infections in the urinary tract, surgical,…
Data of table 2 demonstrates that E.coli strains produced sort of difference in resistance. 310217 type showed resistant to all antibiotics investigated whereas, E. coli strain 704476/2 showed sensitivity to all antibiotics experimented. Table 3. Results (below) for the microbial toxin tests performed on selected bacterial organisms.…
Unknown Organism Report I have identified my Unknown Organism #1 as Escherichia coli, or E. coli. My Unknown Organism is an anaerobic gram-negative, unicellular eubacteria. It belongs to the genus Escherichia, which is named after Theodor Escherich, a German pediatrician. E. coli is usually found in the colon of mammals, explaining the name “coli” meaning from the colon. It’s classified in the order of enterobacteriales, and the family of enterobacteriaceae.…
Malabanan, Joshua Yran P. Professor Cynthia Solem English 1A 05 December 2014 How E. Coli Can Make Us Die A 4-year-old Oregon girl has died from medical complications possibly resulting from an E. coli infection contracted sometime just before Labor Day weekend, according to the girl’s uncle, who spoke with Food Safety News. Serena Profitt of Otis, OR, died Monday at Doernbecher Children’s Hospital in Portland. Her symptoms of E. coli infection first appeared around Aug. 29 with bouts of diarrhea, said Travis Profitt, Serena’s uncle.…
Based on the laboratory tests provided, it can be determined that the unknown organism can be identified as Pseudomonas aeruginosa (P. aeruginosa). This organism is an opportunistic pathogen that can infect non-mammalian, plants, and humans. P. aeruginosa belongs to the bacterial family Pseudomonadaceae, and is a gram-negative rod that approximately measures 0.5 to 0.8 µm by 1.5 to 3.0 µm. It can normally be found in water and soil. Its single polar flagellum makes it motile, and it is known to be one of the fastest swimming bacteria found in hay infusion and pond water (Crittenden, Trussell, Hand, and Howe 2012).…
My unknown bacteria’s, E.coli, morphology was that the bacteria were rod shaped. E.coli can be found plentifully in nature. E.coli can be found in the gut of endotherms, which are warm-blooded organisms. E.coli can also be found in the normal flora of the human stomach and allows numerous beneficial functions that include the production of vitamin (Nordquist 1). Most strains of E.coli are harmless, however the strain E.coli does have some pathogenic strains that cause…
These bacterium are easily detected; although, coliform bacterium are not disease producers, they are often found in association with other microbes that are capable of causing diseases. Therefore, their absence from water is a good indication that the water is safe for human…
1. Non-pathogen name: Bacillus subtilis 2. Description of non-pathogen: B. subtilis is a mesophilic, gram-positive bacillus that is commonly found in soil, although it can also survive in plants (1). B. subtilis are facultative aerobes, using butanediol fermentation or nitrated ammonification when oxygen is unavailable (1). The bacillus is motile by using a single flagellum and commonly forms biofilms which contain several B. subtilis all traveling in the same direction (1).…
coli in drinking water is not something that is typically the topic of conversation, but it is something that is important to health and the environment’s safety. The contamination of drinking water can cause many illnesses with even more gruesome symptoms. The effect of E. coli in natural environments can cause places to be closed. The testing of E. coli isn’t a very hard process and can save the life of a friend or a fish. No matter where the contamination has happened, someone will suffer because it is there, and that is why it was decided to test the main points of water intake in the…
The development of advanced microscopes has enabled scientists to further their investigation on the criteria for life. As a result, biologists have been confronted with a baffling question: is there a size limit on life? If so, then just how small can something be before it can no longer be considered alive? Ever since the discovery of nano-sized particles called “nanobacteria” or “nanobes”, researchers have been scrambling to unravel and analyze the mysterious functions of these purported organisms. Their existence has raised many controversial questions, including whether or they are alive.…
The bacteria used in the experiment are Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Klebsiella pneumoniae, and Salmonella pneumonia. These all bacteria will be culture in the nutrient broth. The first stage is making Nutrient Broth. Weigh out 5.8 grams of nutrient broth powder.…
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…
