Escherichia coli

codons, called synonymous codons. If the ultimate goal of protein translation is to produce the encoded amino acid, each synonymous codon should be used equally. Interestingly however, biased usage among synonymous codons occurs in organisms like Escherichia coli and yeast. Codon usage bias refers to the fact that some synonymous codons are used more frequently than others when encoding the same amino acid. Very little is understood about codon usage bias in vertebrates. It is known that natural…

1. Penicillin kill bacteria by meddling with the capacity to blend cell divider. In this grouping, Escherichia coli were brooded in penicillin for 30 minutes. The bactericidal kills the bacteria. Also, bacteriostatic is a keeps bacteria organisms from developing. 2. Antibiotic resistance happens when bacteria organisms change somehow that decreases or wipes out the adequacy of medications, chemicals, or different specialists intended to cure or avoid contaminations. The microscopic organisms…

than product B; whilst the third hypothesis proposed that product A would be most active against S.aureus. The assumption that Staphylococcus aureus would be more susceptible to the bactericidal effects of the tested antibacterial agents than Escherichia coli was based on the species’ classification as gram-positive. In order to be classified as gram-positive, a…

A number of toxins, created by molds on food can cause severe illness. Produce, cheese and breads are the most common foods where molds are created. One easy way to prevent getting contaminated by infected food is not to taste foods that smell or look irregular. Another easy way to prevent contamination is to stick with the recommended dates on the food labels. Our classmate Ron mentioned E.Coli and Salmonella, these two are food borne bacterias with salmonella being the most common cause of…

Urinary tract infection is one of the most common bacterial infections in childhood, affecting up to 8 % of girls and 2 % of boys before the age of 11 years. The presentation of UTI varies with age; in infancy, symptoms are often generic including fever, lethargy or irritability, vomiting, diarrhea, poor feeding, failure to thrive, septicemia and febrile convulsion. Several textbooks mention prolonged neonatal jaundice as one symptom of UTI. Jaundice is very common in newborn babies occurring in…

Many diseases and parasites live in the unsanitary and dirty water. Nine out of 10 individuals that get sick from dirty water are children, most common diseases are; rotavirus, Campylobacter jejuni, enterotoxigenic Escherichia coli, Shigella spp. and Vibrio cholerae O1 (Ashbolt, 229–238), there are many more diseases that may be present in poor drinking water but these are the main diseases. According to the Center for Disease Control (CDC), rotavirus is a very contagious…

coli is 37 oC. The temperature with the least amount of growth for E. coli is 65 oC. This is because it is past the maximum temperature, and therefore the bacteria started dying. The optimal temperature for B. stearothermophilius is 65 oC. The temperature with the least amount of growth…

Staphylococcus aureus and Escherichia coli are common examples of multidrug resistant organisms, which causes severe infections in the community including hospitals [9]. Multidrug resistance makes the treatment of bacterial infections more difficult [9], and patients in the intensive…

Kalyani et al (2009) studied an isolated strain of Pseudomonas sp. SUK1 from the waste disposal sites of local textile industries in India, with the objective of evaluate an ecofriendly textile dyes biodegradation. To isolate the microorganism, they first collected a soil sample from the waste disposal site and inoculated the sample in a nutrient medium with a dye. Then they incubated and plated in agar with dye. The colonies that had a halo of decolorization were selected to be submitted to…

bacteriophage is non-living and the bacterium is living. The bacteriophage in the text is the T-4 bacteriophage which is 200nm in length and 80-100nm wide. The bacterium in the text is the E. coli (Escherichia coli) which is 3000nm in length, which is significantly bigger than the T-4 bacteriophage. Also, E. coli bacterium eaten could cause severe stomach cramps when the E.coli strains live in the human intestine, they also provide vitamin K and B-complex. Whereas, a T-4 bacteriophage or T-even…
