In a single day, two 19-year-old women and one 20-year-old man sought treatment at a university health clinic, complaining of acute diarrhea, nausea, and vomiting. No blood was found in their stools. One of the women was found to have a urinary tract infection. All three had eaten lunch at a nearby health food store the previous day. The man had a sandwich with tomato, avocado, sprouts, pickles, and sunflower seeds. One woman had a pocket sandwich with turkey, sprouts, and mandarin oranges; the other woman had the lunch special, described in the menu as a “delightful garden salad of fresh organic lettuces, sprouts, tomatoes, and cucumbers with zesty raspberry vinaigrette dressing.”All had bottled water to drink.

- Alette, a 17-year-old Haitian woman, presented to a women’s clinic complaining of watery and foamy bowel movements 5 to 10 times a day. She had also experienced abdominal cramps and a low-grade fever. The physician ordered a stool sample for routine O&P as well as for culture and sensitivity tests. The culture and sensitivity tests were reported as negative for enteric pathogens. The laboratory technician performed a routine O&P examination, including a permanent trichrome stain. No parasites were observed. Two days later, a repeat O&P was ordered. The patient was now diagnosed as HIV-positive. The repeat sample was again examined for ova and parasites by routine laboratory procedures. This time, the technologist noted oval forms of the wet preps that were highly refractile and suggestive of fungal cells, but no budding was seen. The trichrome permanent stain did not confirm the laboratory technician’s suspicions. Not satisfied that the sample was negative, the laboratory…arrow_forwardThis graph shows incidence of severe diarrhea (spelled diarrhoea here) in a single country from January 2006 to July 2018, as measured by hospital admission.

The speeches drag on for a couple of hours, but finally all the faculty and students can dig into the food: chicken salad, tomatoes, onions, salad, and custard pie. By evening, the whole department, except for two vegetarian students who did not eat the chicken salad, is stricken with nausea, vomiting, retching, and abdominal cramping. Several individuals complain of diarrhea. One patient shows signs of shock (low blood pressure). Blood and stool samples are collected from patients, and an analysis of all foods served at the meal is conducted. Bacteria can cause gastroenteritis (inflammation of the stomach and intestinal tract) either by colonizing and replicating in the host, which is considered an infection, or by secreting toxins, which is considered intoxication. Signs and symptoms of infections are typically delayed, whereas intoxication manifests within…arrow_forward
