Flooding after two weeks of heavy rainfall in Tooele, Utah, preceded a high rate of diarrheal illness. Giardia intestinalis was isolated from 25% of the patients. A comparison study of a town 65 miles away revealed that were was diarrheal illness in 2.9% of the 103 people interviewed. Tooele has a municipal water system and a municipal sewage treatment plant. Explain the probable cause of this epidemic and method(s) of stopping it. What would a fecal coliform test have shown?

- A 50-year-old patient was hospitalized in the infectious department of the district hospital on the 4th day of illness with suspected typhoid-paratyphoid disease. The disease began with a gradual rise in temperature, which reached a maximum level of 39 degrees C on the 3rd day. Complaints of headache, loss of appetite, general weakness, constipation, bloating and flatulence. From the anamnesis: a family member of the patient 2 months ago fell ill with typhoid fever. Objectively: remitting fever, pale skin, moderately bloated abdomen, slight enlargement of the liver and spleen, mental retardation. There is no rash. 1-What serological tests should be used to establish the etiology of typhoid? 2-What are the features of serological diagnosis in the early stages of the disease?
