Problems in determining immune status in borderline specimens in an enzyme immunoassay for rubella immunoglobulin G antibody.

A total of 374 sera, found by enzyme-linked immunosorbent assay (Rubazyme; Abbott Laboratories, North Chicago, Ill.) to have borderline rubella antibody levels, were tested by hemagglutination inhibition. All sera had Rubazyme indexes in the range of 0.500 to 1.499. Rubazyme sensitivity was 59.0%, and specificity was 80.8%. The predictive value of Rubazyme-positive result was 91.4%, and that for a negative result was 36.4%. Immune and nonimmune results were significantly different between the two methods (P less than 0.001). The same sera were retested with the Rubazyme test, with an inter-run agreement of 75.3%. A significant difference in Rubazyme indexes between runs (P less than 0.001) was observed. An alternative method of testing specimens in the range close to the Rubazyme index cutoff value of 1.000 may be indicated.

Intestinal parasitosis among Southeast Asian immigrants in New Mexico.

Results of an intestinal parasite survey of 776 Southeast Asian immigrants in New Mexico are presented. Parasites were found in 71.8 per cent of the patients; 44.3 per cent were multiply infected. Twenty different parasites were identified, some of which are not common in the United States.

Feline plague in New Mexico: report of five cases.

Naturally acquired plague was diagnosed in 5 domestic cats. The cats apparently contracted the disease through contact with sylvatic rodents or their fleas in plague-enzootic areas. The diagnosis was confirmed by direct immunofluorescence and isolation of Yersinia pestis on culture of abscess material. Abscess formation, lymphadenitis, lethargy, and fever were consistent clinical findings.

Delayed type hypersensitivity in guinea pig infected subcutaneously with Naegleria fowleri Carter.

A soluble fraction, derived from Naegleria fowleri trophozoites disrupted by freeze-thawing, was tested for antigenic properties. Intradermal injections of this preparation were administered to guinea pigs previously infected subcutaneously with viable N. fowleri. Delayed hypersensitivity to the antigen and loss of weight, the diagnostic symptom of visceral naegleriasis, were observed in the surviving animals. Fifty percent of the guinea pigs, however, did not lose weight and had a reduced reaction to the antigen. The apparent differences in the immunocompetence of guinea pigs inoculated subcutaneously and intranasally with N. fowleri are compared.
