Salmonella Typhi

Salmonella Typhi Meliza Simeon Kaplan College Salmonella typhi Salmonella typhi was originally isolated in 1880 by Karl J. Erberth in lien sections and mesenteric lymph nodes from a patient who died from typhoid. In 1881, Robert Koch confirmed a related finding by Gaffky and accomplished in cultivating the bacterium. Although, breakup of the typhoid bacillus from other enteric bacteria was unfastened due to the lack of differential characters. In 1896, it was demonstrated that the serum from an animal immunized with the typhoid bacillus agglutinated (clumped) the typhoid bacterial cells, and it was shown that the serum of patients afflicted with typhoid likewise agglutinated the typhoid bacillus. Serodiagnosis of typhoid was thus made possible by 1896 (Todar, 2009). Habitat/man-made lake It inhabits the lymphatic tissues of the small intestines, liver, spleen, and the bloodstream of infected humans only. It is non cogn ize to infect animals. S. typhi is most commonly found in countries with scant(p) sanitation systems and lack of antibiotics, putting Africa, Asia, and Latin America in a high risk group. In the United States or so four degree centigrade cases occur each year, and 75% of these ar acquired while traveling internationally. (Typhoid Fever, 2010). geomorphology and asperity Factors S. typhi is a grand- ostracize enteric bacillus that belongs in the family of Enterobacteriaceae. It is a motile, facultative anaerobe that is susceptible to numerous antibiotics. Presently, one hundred heptad strains of this organism have been isolated. Many of these strains contain change metabolic characteristics, levels of virulence, and multi-drug underground genes that complicate treatment in areas that resistance is prevalent. S. typhi has a medley of characteristics that make it an effective pathogen. This species has an endotoxin typical of gram negative organisms, as well as the Vi antig en which is comprehend to increase...If you! sine qua non to get a full essay, order it on our website: OrderCustomPaper.com
