salmonella and Shivella toxins and antigens, and related illnesses

Solutions

Expert Solution

Salmonella

Antigen; three types of antigens.

1)somatic or cell wall antigen-heat stable and alcohol resistant

2)surface(envelope ) antigens-they mask o antigens and the bacteria will not be agglutinated with o anticera.one specific surface antigen is the Vi antigen.

3)flagellar antigen-heat labile protiens.anti flagellar antibodies can immobilize bacteria with corresponding h antigens

Toxins

Salmonella cytolethal distending toxin(s-cdt) it is also called as typhoid toxin induces dna damage in eukaryotic cell

Illness

Typhoid fever,gastroenteritis,salmonellosis.

Shijella

Antigen

Enterotoxin,cytotoxin and plasmid encoded proteins that induce bacterial invasion of epithelium

Toxin

2 major groups,Stx-1 and Stx-2

Illness

Shigellosis with symptoms of diarrhea,fever and stomach cramps.

An outbreak of Salmonella-related illness was attributed to ice cream produced at a certain factory. Scientists are interested to know whether the mean level of Salmonella in the ice cream is greater than 0.2 MPN/g. A random sample of 20 batches of ice cream was selected and the level of Salmonella measured. The levels (in MPN/g) were: 0.593, 0.142, 0.329, 0.691, 0.231, 0.793, 0.519, 0.392, 0.418, 0.219 0.684, 0.253, 0.439, 0.782, 0.333, 0.894, 0.623, 0.445, 0.521, 0.544 a)Read the data...
