Molecular detection of brucellosis in dromedary camels of Qatar by real-time PCR technique.

BACKGROUND AND METHODOLOGY: Brucellosis in livestock causes huge economic loses of developing countries and demonstrates a serious health risks to the patrons of infected dairy goods and meat. Prevention of brucellosis in cattle relies on the trustworthiness of the techniques utilized to detect the causative pathogen. In the current investigation, we described the exploration of the well-known real-time PCR technique based on the Brucella-specific IS711 with different tissue samples of dromedary camels in Qatar.

RESULTS

The findings of the real-time PCR unveiled the occurrence of Brucella spp in 60 % of lung tissues, 71.42 % of liver tissues, 72 % of spleen tissues, 25 % of kidney tissues, and 42.42 % of placental fluid samples. Among them, the liver tissues and spleen tissues possessed the highest number of positive results, whereas kidney tissues displayed the lowest number of positive results for Brucella spp.

CONCLUSION

The findings of this investigation discloses that PCR technique is a sensitive and specific technique for the identification of Brucella spp. in dromedary camels. Most of the tissues samples showed the presence of Brucella spp. and also we concluded that there is a need for further studies to be conducted in order to identify specific species of Brucella.
