Isolation and identification of Brucella suis biotype 2 from epididymal puncture performed on a boar affected with brucellosis

摘要

The causal agent of swine brucellosis is Brucella suis. Within the scope of the kinds of Brucella suis, there are five biotypes, but only biotypes 1, 2 and 3 lead to swine infections. Human infections with Brucella suis biotype 2 are rarely registered. Swine brucellosis is widespread all over the world. It has been noted that the incidence of swine population infected with Brucella suis in Western Europe has been increasing during the recent years. The goal of this project was to isolate, identify and typify the causal agent from epididymal puncture performed on a boar with conditions suspicious of brucellosis, using standard microbiological methods. The results of the research show that Brucella suis biotype 2 can be successfully isolated and identified from a sample obtained by means of epididymal puncture of live animals. Therefore, epididymal puncture gives us a certain, reliable and important sample derived from a live animal for a direct diagnostic of boar brucellosis. The above mentioned first isolate of Brucella suis biotype 2 epididymal puncture, has been marked as K-1.
