Abstract
Neosporosis caused by protozoa Neospora caninum, is a leading cause of abortion in cattleworldwide.The aim of the present study was to analyze the seroprevalence of N. caninum and associatedrisk factors in cattle of Jammu.A total of 180cattle serum samples were collected from four areas of Jammu, namely, Jammu, Akhnoor, R.S. Pura and Bishnah.The serum samples were tested using Competitive Enzyme Linked Immunosorbent Assay to detect N. caninum antibodies. Out of 180 samples tested, 25 were positive yielding the overall prevalence of 13.88 per cent. The highest prevalence was recorded from Akhnoor (18%) followed by Jammu (14.80%), R.S. Pura (8.82%) and Bishnah (6.67%). For analysis of risk factors associated with neosporosis, eleven parameters were taken into consideration viz., type of herd, breed, age, origin of animals, method of rearing, presence of dogs, parity, history of abortion, history of repeat breeding, method of disposal of foetus and foetal membranes, hygiene and disinfection of farm.. The factors that were significantly associated with N. caninum infection were method of disposal of foetal membranes (OR = 6.10, p = 0.0001)and presence of dogs (OR = 3.02, p = 0.0139). The overall prevalence of 13.88 per cent of N. caninum in cattle signifies the importance of screening the cattle population of Jammu regardless of any clinical symptoms in order to learn about the exposure of the animals to Neospora caninum
