A serological survey of bovine brucellosis in India.

چکیده
A serological survey of brucellosis in cattle and buffalo was performed in 23 States of India. A total of 30,437 bovine samples, comprising 23,284 cattle and 7,153 buffalo (Bubalus bubalis), were screened. The screening initially used the rose bengal plate test: doubtful and positive samples were then titrated in the serum tube agglutination test. The overall prevalence rate of antibodies was 1.9% in cattle and 1.8% in buffalo. In a detailed study of 47 organised farms in the southern State of Karnataka, 207 of 4,995 (4.1%) serum samples from cattle showed titres for brucellosis. This result was in contrast to the low rate of seropositive results reported in cattle owned by individual farmers in Karnataka (0.7% of 2,424 serum samples). In organised farms with a history of abortion, placenta retention and repeat breeding, the prevalence rate was 17%.

The aim of present study was to compare the diagnostic performance of the different Brucella abortus antigen based serological and molecular tests such as Rose Bengal Plate Test (RBPT), indirect enzyme linked immunosorbent assay (I-ELISA) and polymerase chain reaction (PCR). Out of 89 samples, 44 were positive by I-ELISA, 18 by RBPT and 21 by PCR. Substantial agreement was observed between PCR ...

The avidin-biotin enzyme-linked immunosorbent assay (A-B ELISA), for use in surveillance for bovine brucellosis in India was developed and calibrated using the indirect brucellosis ELISA kit of the International Atomic Energy Agency (IAEA) as a reference. The reagents used in the A-B ELISA were as follows: the smooth lipopolysaccharide of Brucella abortus strain 99 (antigen); biotinylated anti-...
