notes on pathogens 1. Staphylococcus aureus. S. aureus produces six types of enterotoxins (A to F). The type A is most often incriminated in outbreaks of staphylococcal food poisoining. Acute staphylococcal food poisoining is caused by the ingestion of preformed toxin contaminated food (often diary products).

Samples collected for surveillance and monitoring purposes are often multi-component products for which there are no microbiological standards or guidelines.

متن کاملMicrobiological examination of sebeel water.
Water samples from clay storage jugs ("zeers") located in homes and at public watering stands ("sebeels") at streets, mosques, and schools were examined. Coliforms, fecal coliforms, and fecal streptococci were detected in 100, 69, 88, and 91.56% of the samples, respectively. The general microbiology of the water and some factors affecting microbial load were studied. The predominant bacterial g...
متن کاملMisinformation from sputum cultures without microscopic examination.
Only 13 of 38 hospital laboratories surveyed include a Gram stain routinely in microbiological sputum examination. In a prospective three-hospital study, 60% of over 1,200 "sputum" specimens consisted predominantly of saliva, as judged by cell composition. Compared with the results of cultures in which microorganisms presumptively identified on sputum smears were specifically sought ("directed ...
