Evaluation of the card test for diagnosis of human brucellosis.

The relative efficacy of the card test in the diagnosis of human brucellosis was evaluated by comparison with four other tests: the standard tube agglutination test, centrifugation agglutination test, 2-mercaptoethanol degradation technique, and 2-mercaptoethanol centrifugation agglutination test. A total of 1,701 serum specimens from persons with various degrees of potential exposure to brucella organisms or cross-reactive antigens were used in this study. In comparison with standard tube agglutination results, the card test had a sensitivity of 95.3% and a specificity of 84.1%. The card-test antigen was nonreactive with serum specimens from tularemia patients and cholera vaccinees. Our data indicated that this test measures both immunoglobulin G and immunoglobulin M agglutinins. The value of the card test in the presumptive serological diagnosis of clinical brucellosis in humans appears to be low; however, the card test may be of value in serological surveys to delineate high-risk populations.

Leptospirosis in zoo workers associated with bears.

Leptospirosis due to Leptospira interrogans serovar icterohaemorrhagiae was diagnosed in two zoo animal keepers. The implicated source of infection was bear cubs that had microscopic agglutination antibody titers to leptospires of the Icterohaemorrhagiae serogroup.

An epizootiologic study of anthrax in Falls County, Texas.

In June and July, 1974, an anthrax epizootic in Falls County, Texas, resulted in the death of 236 animals (228 cattle, 5 horses, 2 mules, and 1 pig) on 48 premises. Death rates were highest for horses (18.2%) and bulls (16.8%). The epizootic was apparently precipitated by drought, and infection appeared to be the result of ingesting intrinsically contaminated soil and grass. Human illness was not associated with the epizootic.

A perspective of simian tuberculosis in the United States-1972.

Despite the availability of effective control measures, simian tuberculosis continues to be a major colony management problem. In 1972, 909 cases of simian tuberculosis were reported to the Center for Disease Control. Most of the cases (838) were in rhesus monkeys (Macaca mulatta). The attack rate was higher for animals conditioned by commercial importers prior to sale (6.6%) than for animals received shortly after importation without conditioning (1.2%) . Failure to apply control measures effectively and consistently both in trade channels and at the user level is a significant factor in peptuation of the problem.

Melioidosis in imported non-human primates.

In 1969, five cases of melioidosis in three separate outbreaks were diagnosed in nonhuman primates in the United States. In the first outbreak, two stump-tailed macaque monkeys (Macaca arctoides) developed signs of the disease approximately 6 months after purchase. A third animal, a chimpanzee (Pan troglodytes), probably acquired its infection from one of these monkeys. Two other unrelated cases involving a pig-tailed monkey (Macaca nemestrina) and a rhesus monkey (Macaca mulatta) were diagnosed. These monkeys had been imported 3 years and 6 months, respectively, prior to the recognized onset of their disease. These cases represent the first known occurrences of spontaneous melioidosis in nonhuman primates in the United States.
