AI Article Synopsis
- A serologic study was conducted on 7 species of cetaceans in Japan to test for Brucella infection using serum samples.
- One serum sample from five melon-headed whales tested positive for Brucella abortus, while no samples were positive for B. canis.
- The positive serum displayed specific reactions to B. abortus in further analysis, indicating that the infection is present in this whale population and suggesting that their bacterial antigen similarity is closer to B. abortus.
Article Abstract
A serologic investigation of Brucella infection was performed in 7 species of cetaceans inhabiting along the coast of Japan. A total of 32 serum samples were examined by enzyme-linked immunosorbent assay (ELISA) using Brucella abortus and B. canis antigens. One serum sample from five melon-headed whales (Peponocephala electra) was positive for B. abortus. No serum sample showed positive for B. canis. The ELISA-positive melon-headed whale serum demonstrated a strong band appearance only against B. abortus antigens in Western blot analysis. Many detected bands were discrete, while some of them had a smeared appearance. The present results indicate that Brucella infection occurred in melon-headed whale population and the bacterial antigenicity is more similar to that of B. abortus than B. canis.
