background: neospora caninum is a protozoan parasite from phylum apicomplexa and an important agent causing abortion in cattle which produce notable economic loss all around the world. methods: dot-elisa was set up performing checker board procedure and then 178 sera of cattle examined with commercial indirect elisa and direct agglutination test (dat) were also evaluated by dot-elisa afterwards...

When brucellosis false positive serological reactions happen in cattle, the serial use of pairs of specificity-correlated serological tests (rose bengal, complement fixation, competitive ELISA) results in specificities lower than expected. In this situation, highly specific tests, such as the indirect ELISA used alone, may be more adequate than serial testing.

An enzyme-linked immunosorbent assay (ELISA) and indirect fluorescent-antibody test were used to detect antibodies to Borrelia burgdorferi, the causative agent of Lyme disease, in Peromyscus leucopus (white-footed mouse). Of the 661 mice captured in Connecticut, Rhode Island, and New York during 1980 and 1983 to 1987, 166 (25.1%) had antibodies to B. burgdorferi by ELISA. Comparative analyses o...

An indirect enzyme-linked immunosorbent assay (ELISA) was developed for the detection of IgG serum antibodies to swine Sendai virus. To evaluate the preliminary potential of ELISA, sera from 10 healthy pigs and 34 sera from finishing pigs suffering from respiratory signs were tested. The results were compared with those obtained from the same sera by hemagglutination inhibition assay.

The recent invasion of southern California by the glassy-winged sharpshooter (GWSS), Homalodisca coagulata (Say) (Hemiptera: Cicadellidae), has triggered a statewide control eVort. Management of GWSS will include biological control using resident and imported natural enemies. Currently, very little information is available on the role of generalist predators in suppression of GWSS eggs, nymphs ...
