Salmonella Essay

Infections with Salmonella species represent a significant public health problem due to their large and varied animal reservoir, presence of human and animal carrier states, as well as the lack of coordinated programs for control. Although cases of human salmonellosis have been steadily declining since 1995, it still remains one of the most important human food-borne diseases. Salmonella has evolved to live in the gastrointestinal tracts of animals, thus the primary sources of contamination are

been recalled for salmonella. Barber Foods has expanded its recall to include its line of stuffed chicken products that may have been exposed to salmonella, according to an announcement by the U.S Department of Agriculture given today. The recall list included almost 90 different raw food packages that were produced between February and May of this year. In that time, the products were shipped across the US and Canada, and recall is of the highest priority. Exposure to salmonella is not taken lightly

In the fall of 1984 in The Dalles, Oregon there was a Salmonella Typhimurium outbreak that caused gastroenteritis in a total of 751 people. There were two waves of the outbreak, the first being September 9th through the 18th and the second was September 19th through October 10th. An investigation of the outbreak determined that the origin of the outbreak was from 10 different restaurants and eating at their salad bars. During the epidemiological investigation, no water supply, single food item

Salmonella enterica serovar Typhimurium (S. Typhimurium) is a pathogen commonly associated with localized intestinal infection in humans. For its survival and propagation as a facultative intracellular pathogen, this Gram-negative bacterium has developed a variety of ways to manipulate host cell processes (Malik-Kale et al. 2011). Besides phagocytic internalization (by, e.g., macrophages, neutrophils, or dendritic cells), Salmonella infection is characterized by the bacterial-induced uptake of the

A group of researchers from Canada have discovered that there is a gene that confines an antibody from Salmonella. They discovered that this gene is found in broiler chickens. Broiler chickens aren’t used as much for egg production. These chickens are known for being raised on farms and then butchered for meat. The researchers took their information and published a journal where the information and research can be found. The gene itself is named fosA7; it got its name because it carries a high level

Transmission, Treatment and Prevention of Salmonella Abstract Salmonella is a gram-negative rod, which is known to infect humans, birds, and other mammals by invading and irritating the intestines. It is more common in poultry and swine which, if consumed, can cause diarrhea, nausea, vomiting, and stomach cramps. The infectious disease can be found almost everywhere and anywhere, including in water, animal feces, raw poultry, and raw seafood. Animals consume salmonella from the soil or contaminated processed

Salmonella Introduction Salmonella is known as a gram-negative, rod shaped bacillus. It is a facultative anaerobe in the family Enterobacteriaceae (Todar). There are more than 1,000 known types of Salmonella, with ranging levels of toxicity (Jones), accounting for 60% of all bacterial diseases (Curtello). Salmonellosis has affected over 1.4 million people per year in the United States, including more than 500 fatal cases (Jones). This organism has a wide host range with abilities to attack both animals

The food borne illness I have chosen is salmonella. Question 1: What is the infectious agent (pathogen) that causes this infectious disease? The infectious agent (pathogen) that causes salmonella is called salmonella enteriditis. The bacteria is larger than a virus; but, is visible to the eye with the microscope. It is rod-shaped, gram negative, non-motile bacteria that does not form spores. Interestingly enough it communicates to its fellow bacteria via AHL. It infects the cell, multiplies

Health Issues: Salmonella Outbreak Introduction: An area of particular importance to organizers of community health imperatives is that concerning the containment and prevention of epidemic illness. Especially in the case of foodborne illness, the root cause can be difficult to isolate. This is well demonstrated by the community health problem delineated in the article by Falco (2012), which concerns a recent and proliferating outbreak of a salmonella strain called Salmonella Bareilly. As the

Salmonella enterica (formerly Salmonella choleraesuis) is a rod-shaped, facultatively anaerobic, flagellated, Gram-negative bacterium, a member of the genus Salmonella, belonging to the family Enterobacteriaceae. A number of its serovars are serious to human as well as animal pathogens. Among these sarovars, Salmonella enterica serovar Typhi is one of the most important food-borne pathogen causing typhoid. The genome of S. Typhi has a clonal nature but variations have yet been observed among its
