Studies on the infectious agents of abortion in buffalo (Bubalus bubalis) are uncommon and very few is known about his health status in Italy. In order to investigate this situation, a serological survey has been carried out in 9 buffalo farms of Central Italy with history of reproductive disorders. During 2005, 505 buffalo sera were tested using commercial antibody-detection ELISA for BoHV-1, BVDV (IDEXX), Chlamydophila abortus (CIVTEST), Leptospira hardjo (EVL-diagnostic division) and Neospora caninum (VMRD, Inc.). All buffalos were negative for L. hardjo while 72 (14.26%) sera had antibodies against BVDV. Overall prevalence of 7.33% and 2.38% has been estimated respectively for BoHV-1 and C. abortus. All herds were infected by N. caninum with a prevalence of 50.10%. A closed association between seropositivity and abortion was found only for N. caninum infection and the prevalence value was significantly higher (P<10-4) in the aborting group (79.45%) than in the non-aborting group (45.14%). Abortion occurred in the first trimester of pregnancy, and the administration of Toltrazuril and/or Sulphadiazine and Trimethoprim to all the animals was efficacious in reducing N. caninum infection and in preventing the reproductive disorders. This study suggested a correlation between N. caninum infection and abortion in buffalo.

Abstract
Studies on the infectious agents of abortion in buffalo (Bubalus bubalis) are uncommon and very few is known about his health status in Italy. In order to investigate this situation, a serological survey has been carried out in 9 buffalo farms of Central Italy with history of reproductive disorders. During 2005, 505 buffalo sera were tested using commercial antibody-detection ELISA for BoHV-1, BVDV (IDEXX), Chlamydophila abortus (CIVTEST), Leptospira hardjo (EVL-diagnostic division) and Neospora caninum (VMRD, Inc.). All buffalos were negative for L. hardjo while 72 (14.26%) sera had antibodies against BVDV. Overall prevalence of 7.33% and 2.38% has been estimated respectively for BoHV-1 and C. abortus. All herds were infected by N. caninum with a prevalence of 50.10%. A closed association between seropositivity and abortion was found only for N. caninum infection and the prevalence value was significantly higher (P<10-4) in the aborting group (79.45%) than in the non-aborting group (45.14%). Abortion occurred in the first trimester of pregnancy, and the administration of Toltrazuril and/or Sulphadiazine and Trimethoprim to all the animals was efficacious in reducing N. caninum infection and in preventing the reproductive disorders. This study suggested a correlation between N. caninum infection and abortion in buffalo.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
