Seroepidemiological pattern of leptospirosis in bovine of South Gujarat, India

Abstract

Aim: Seroepidemiological study of leptospirosis in cattle of various South Gujarat district (Navsari, Tapi, Surat, Valsad). Materials and Methods:Whole blood samples were collected randomly from different age groups, and breeds of cattle of either sex reared in different districts (Navsari, Surat, Tapi, Valsad) of South Gujarat. To obtain serum, whole blood was kept in slanting position in 9.0 ml plain vacutainers until serum extracted out of the whole blood. Then these 9.0 ml plain vacutainers were centrifuged at 7000 rpm for 10 min. The straw colored serum was then collected in 1.5 ml sterile cryo vials and aliquoted and stored at −20°C for microscopic agglutination test. Results:In the present study, overall 12.81% (51/398) seroprevalence were recorded with highest seroprevalence (47.06%, 24/51) from Valsad followed by Navsari (9.14%, 18/197), Surat (6.90%, 2/29) and Tapi (5.79%, 7/121) among cattle. The seroprevalence rate of breed and sex wise did not differ significantly (p≤0.05). Maximum incidence of seropositivity was found above 4 years (16.32%, 39/239) of age group followed by animals between 1 and 4 years (9.68%, 12/124). Thus, the age was significantly influencing the seropositivity (p≤0.05). In cattle out of 398 sera screened, 51 were positive with one or more serovars. The highest seropositivity was recorded against serovar Pomona (28.89%).Conclusions: Overall 12.81% seroprevalence of leptospirosis in apparently healthy and clinically ailing bovine of South Gujarat indicating potential zoonotic risk to farmers, labor, and animal owners.

Investigation on the Distribution of Leptospira Serovars and its Prevalence in Bovine in Konkan Region, Maharashtra, India

“…Antibodies against different serovars have been reported from Karnataka (4.6%) (Srivastava et al, 1983), Andaman (24.2%); Tamil Nadu {51.4%-(87% in endemic farm also reported by (Natarajaseenivasan et al, 2011)} and Andhra Pradesh (10.5) {Cattle-12.2% and buffaloes (11.1%) mainly to Patoc, Icterohaemorrhagiae (Srivastava et al, 1983)} Maharashtra (7.3%) and Uttar Pradesh (4-8%) (Srivastava and Kumar, 2003), Gujarat (12.8%) (Patel et al, 2014) and…”

Seroepidemiology of Caprine Leptospirosis in South Gujarat Region of India

“…In India, seroprevalence of leptospirosis among goats has been reported since long back from different states (Ball and Sheikh, 1958;Sharma et al, 2003;Meenakshisundaram and Chellapandian, 2010;Agrawal et al, 2005;Srivastava, 2008;Prakssh Krupakaran et al, 2009;Balakrishnan, 2012;Vamshi Krishna et al, 2012;Patel et al, 2014). However, in India including South Gujarat, vaccination strategy for leptospirosis is not followed in domestic animals.…”

Carrier status and seroprevalence of leptospirosis in cattle of South Andaman

“…Generally, cattle are considered as the maintenance host of leptospira and also a potential source of infection to the other animals and human (Ellis, 1994). Various reports of seroprevalence of leptospirosis among cattle are available from different parts of the India (Srivatava et al, 2003, Patel et al, 2014, Panwala and Mulla, 2015, Balamurgan et al, 2013. In A&N Islands also the seroprevalence of leptospirosis among cattle and goat has been reported (Jeyakumar et al, 2002, Sunder et al, 2005, 2014, Sharma et al, 2014, 2006.…”
