Multidrug resistance in plague

Article Abstract:

The worldwide network of World Health Organization laboratories needs to boost its ability to quickly diagnose multidrug resistant Yersinia pestis. This bacterium is responsible for causing bubonic plague, which affected 18,739 people worldwide between 1980 and 1994, 229 of them Americans. A 1997 study reported a strain of Yersinia pestis in a Madagascar boy that was resistant to most antibiotics. This has never been reported before and indicates that the bacterium picked up a gene for drug resistance. This could have serious public health repercussions.

Large community outbreak of cryptosporidiosis due to contamination of a filtered public water supply

Article Abstract:

The contamination of drinking water by cryptosporidium is probably not detected by the current methods of treating public water supplies. An outbreak of gastroenteritis effected an estimated 13,000 people in a county in western Georgia. A parasite, cryptosporidium oocyst, was found in the stools of 39 percent of the patients with gastroenteritis. Studies eliminated the presence of other parasitic pathogens. Inefficient flocculation and filteration may have allowed the parasite to pass into the water supply.
