Background: Most leptospiral infections in sheep and goat are asymptomatic but may result in high fever, abortion, stillbirth, agalactiae. There is a different foraging behavior between sheep and goat that may cause the different prevalence of Leptospira interrogans infection in sheep and goats. OBJECTIVES: The purpose of the present study was to compare the prevalence of L. interrogans antibodies in sheep and goats. METHODS: Blood samples were taken from 246 sheep and 210 goats in 12 herds from 8 areas of Ahvaz where the animals were kept together. Sera were initially screened at dilution of 1:100 against 8 live serovars of L. intrrogans: pomana, canicola, hardjo, ballom, ictrohaemorrhagiae, grippotyphosa, tarasovi and australis using the microscopic agglutination test (MAT). RESULTS: The prevalence of leptospiral infection was 8.53% in sheep and 10.95% in goats. The highest reacting leptospira in both species was L.i. Pomona with a reactor rate of 68.18% in sheep and 56% in goats, followed in descending order by ictrohaemorrhagiae (18.8%), canicula, hardjo and grippotyphosa (each of them 4.54%), in sheep and ictrohaemorrhagiae (28%), canicula (16%) in goats. Statistical analysis showed that were no significant differences between sheep and goat (P=0.428). There were no significant differences among age groups in sheep (p=0.301) and goats (p= 0.363), but there was a tendency in adults sheep and goats (≥3years) to be more seropositive than young sheep and goats. Seroprevalence of leptospiral infection among various areas in sheep (p= 0.464) and goats (p= 0.710) was also not significantly different. CONCLUSIONS: It is concluded that there is no difference between sheep and goats in terms of leptospiral infection when they are kept together in the same herd and husbandry condition.
