Seroepidemiological survey of leptospirosis in slaughtered camels in Golestan province

Abstract

Introduction: Leptospirosis is one of the most common diseases between animal and human around the world. Regarding to the death report of a farmer in Gorgan because of leptospirosis and abnormal mortalities in forest mice in Aliabad-e-Katul, it had seemed to be necessary to investigate Leptospirosis Golestan province. Therefore, this study was considered the prevalence of Leptospira interrogans in serum samples of Golestan province camels.
Materials & Methods: Blood samples were collected from 235 camels of different ages in Golestan slaughterhouse and were examined by microagglutination method. The incidence of leptospirosis was investigated at different ages, sex, and seasons using chi-square method and SPSS.
Results: The results showed that from the total samples, 44 (%18.72) samples had positive serologic response, of which 36 (%81.82), 5 (%11.37), and 3 (%6.81) of samples had one, two and three positive reaction serotype, respectively. Among samples with positive serologic response, %42.60, %31.49, %11.11, %5.55 and %3.70 showed a positive reaction on automnalis, icterohaemorrajiae, canicola serjerohardjo and gripotyphosa, and finally Pomona, respectively. The highest frequency (%38.88) was observed in the 1: 800 Titration. The highest frequency was observed at age of 0 to 2 years old (%18.80), male (%19.46), which was not statistically significant (P>0.05). The highest frequency was observed in autumn (26.82%).
Conclusion: Leptospirosis infection is actively present at the province and it is widely circulated between humans and livestock. This issue is very important in the prevention of disease in livestock and ultimately the health of human society.
