Essays on Escherichia

Between 19th October and 1st December 2015, the CDC reported an outbreak of the Escherichia coli O26 (STEC 026) in Delaware, California, Illinois, Oregon, Kentucky, Maryland, Minnesota, Washington, New York, Pennsylvania, and Ohio. The CDC linked the outbreak to Chipotle Mexican Grill restaurants.

The intestinal symptoms of E. coli infection show up within the first five days after infection and may include:

Loss of appetite Gas Nausea Vomiting Fatigue Sudden watery diarrhea that may turn to bloody stool Cramping of the abdomen Fever In severe cases, the skin becomes pale, urine in blood, a decrease in urine output, and dehydration (Pietrangelo and Kim). Infected people per state include Another short outbreak of a different strain of STEC O26 ...

Application of Epidemiology – Case Study

Information Summative

The statistical analysis of the Good Health Hospital’s medical records reveals the progression of Escherichia coli infection among four hospitalized patients who reported bloody diarrhea, abdominal pain, vomiting and nausea, loss of appetite, flatulence and pyrexia since last week. The summary of these cases presented below in the context of their further analysis. The findings by the CDC revealed that the E. coli manifestations emanated among the affected patients after consuming the spoiled food items attributing to meats and vegetables.

Introduction

E,coli bacteria is a commonly found within the human colon and it is a rod shaped enteric bacterium that grows in ideal conditions of 370 C. The bacterium can be cultured or grown in liquid or solid culture media within the lab. When grown in the ideal conditions, say LB broth, they tend to take a specific pattern while when grown in large amount of media they tend to take a lag phase where growth is minimal or none at all (Ding, Rahman, Purev & Oh, 2010). In the ideal environment, the bacteria tend to grow exponentially with their ...

Abstract

Transformation remains, and hugely significant tool in extending the borders of life sciences and medicine. It can be referred as fixing intracellular DNA into a bacteria or organism through the vector, thus transforming it. This paper uses plasmid pUC18, self-reproducing circular/spherical strands of genes that may be modified. After the bacteria absorb the vector, some proteins not usually synthesized will occur. In this study, a system has been developed to monitor the transmittance of different DNA (genes) from a genetically transformed strain of Saccharomyces cerevisiae to E. coli. This mechanism is centered on yeast strains that contain several integrated ...

“The expression of ampicillin resistance and luciferase enzyme genes by E. coli transformation using the pUC18 and lux plasmids” Abstract The transformation process allows the uptake of DNA from the environment, with the incorporation and expression of genes. During this process, changes in the DNA of the receptor cell occur, producing some selective advantages in some cases, such as resistance to antibiotics. pUC18 and lux plasmids were used to determine the transformation process in Escherichia coli. Cells were made competent by the addition of calcium chloride and heat shock in order to induce the incorporation of the ...

Infection in cancer patient with febrile neutropenia: epidemiology, microbiology and management

Abstract Febrile neutropenia (FN) is characterised by a decrease in neutrophils number to values below 500 cells/ mm3 and an occurrence of fever higher or similar to 38.3ºC. It commonly occurs in cancer patients as a result of chemotherapy regimens. Chemotherapy destroys carcinogenic cells but also attacks in many cases some normal cells including essential elements of the immune system. Fever is one of the characteristic symptoms of FN and is usually associated with the presence of an infection caused by various microorganisms. Bacteria, including Gram-positive isolates (currently dominating) and Gram-negative species (dominant in the 1970s), are usually ...

Abstract

Food safety remains a serious issue in public health. Foodborne disease is the main threat to public health. It occurs when food gets contaminated with pathogens and is then ingested into the body. Food contamination occurs when there is a flaw in the food handling process that allows food to get into contact with the pathogens. Many efforts have been made to deal with food contamination. However, the food industry still faces many challenges some of which are emerging challenges. The dairy sectors are one of the sectors in the food industries facing numerous challenges. Nevertheless, it is one ...

E COLI O157

WHAT IS ECO157? Enterohemorrhagic Escherichia coli O157 or otherwise known as “EHEC O157” is also called as the “verocytotoxin” which produces “shiga toxin” and the end result is EcO157 (Islam, et al., 2014, p.1). The E coli O157 has been reported as a food-borne pathogen known world-wide. One of the harmful effects of E coli O157 is that it can create hemorrhagic colitis that carries severe sequelae such as the hemolytic uremic syndrome as the product of the “shiga toxin” that came from the organism that can act on the human kidney, intestine and other parenchymatous organs (Islam, et ...
