I need some help please!!!
Following a county fair, 160 persons complained of gastrointestinal symptoms. Symptoms included diarrhea (84%), abdominal cramps (96%), nausea (84%), vomiting (82%), body aches (50%), fever (60%; median body temperature = 38.3°C); median duration of illness 6 days (range 10 hr to 13 days).
In this situation , fecal samples should be cultured for all of the following except _______. Why?
A) Salmonella B) Shigella C) Campylobacter D) Enteropathogenic Escherichia coli. E) Giardia lamblia
G. lamblia is not reliably found in stools by microscopic examination, so the 'string test' is used to test for it, in which a capsule is swallowed by the patient, the capsule dissolves to expose a weighted rubber bag which enters the bowel. The bag is drawn up and examined for the bacteria. Yes, it sounds crazy, but it's true!
