Although this pathogen has been reported in soil food and water, the principal mode of transmission is person-to-person contact. There is no known animal reservoir. Shigella is capable of surviving in foods such as milk, whole eggs, flour, and shrimp up to 30 days. Foods incriminated in Shigella outbreaks in the US admit shellfish, fruits, vegetables, chicken, potato salad, heat rice, and Mexican food. Outbreaks of shigellosis micturate been reported in summer camps for the me ntally impaired, among institutionalized persons, and on cruise ships.

Clinial manifestations include an abrupt onset with eminent fever, virulent appearance, and crampy abdominal pain. Profuse watery diarrhea whitethorn be followed by small amount of mucous and damn stools whose enactment is associated with urgency and tenesmus. Antimicrobial therapy of susceptible Shigella strains dramatically shortens the duration of diarrhea, fever, and detail of cummunicability. The choice of antimicrobial therapy can be problematic due to the frequency of antibiotic resistant strains.

Nalidixic acid, TMP-SMX, oxyquino! lones, ceftriaxone, and cefixime are considered nice empiric therapy, but susceptibility testing is recommended for all isolated, and therapy circumscribed accordingly. Complications include rectal prolapse, seizures, leukemoid reaction, hemolytic uremic syndrome, and Reiters syndrome. Strict heed to hand-washing and personalised hygiene is necessary to prevent spread of shigellosis. http://www.sciencenet.com.au/shigella.htm#biochemistry (10/03/04) Medicine http://www.emedicine.com/ped/byname/shigella-infection.htm (10/03/04) downplay: Shigella is the most common cause of bacillary...
