Antibiotic-resistant VD on increase

The incidence of antibiotic-resistant gonorrhea has risenfourfold in the United States since 1984, and is spreading to new areas in the country, according to the Centers for Disease Control (CDC) in Atlanta. The March 6 issue of CDC's MORBIDITY AND MORTALITY WEEKLY REPORT says the 16,608 U.S. cases of gonorrhea reported in 1986 that could not be treated with penicillin marked a 90 percent increase over the number of cases reported in 1985. Florida, New York City and Los Angeles, traditionally considered "hyperendemic' areas for the disease, had 64 percent of the more than 16,000 cases.

Data collected by CDC show that the penicillinase-producingNeisseria gonorrhoeae (PPNG) responsible for the disease is spreading to suburbs of New York City and Los Angeles, as well as to previously unaffected counties in Florida. Although PPNG-caused cases in 1986 represented only 1.8 percent of all reported cases of gonorrhea, some areas were more affected by the resistant strain of bacteria (which produces a penicillindisabling enzyme). For example, 22 percent of the total gonorrhea cases reported in Florida's Dade County in 1986 were caused by PPNG strains.

CDC officials are preparing updated recommendations forprevention, diagnosis and control of PPNG venereal disease-- which, although susceptible to drugs other than penicillin, is both expensive and difficult to treat.
