ABSTRACT.- Pavarini S.P., Sonne L., Antoniassi N.A.B., Santos A.S., Pescador C.A., Corbellini L.G. & Driemeier D. 2008. [Congenital anomalies in aborted bovine fetuses in Southern Brazil.] Anomalias congênitas em fetos bovinos abortados no Sul do Brasil. Pesquisa Veterinária Brasileira 28(3):149-154. Departamento de Patologia Clínica Veterinária, Universidade Federal do Rio Grande do Sul, Av. Bento Gonçalves 9090, Porto Alegre, RS 91540-000, Brazil. E-mail: davetpat@ufrgs.br Abortion, stillbirth and neonatal death are important causes of production losses to the livestock industry. Abortions caused by congenital anomalies may occur sporadically, or appear in epidemics. This retrospective study was conducted at Laboratory of Veterinary Pathology of Federal University of Rio Grande do Sul, and included 307 cases of bovine abortion submitted for diagnosis from September 2001 to March 2007. Most of them were from southern Brazil. Ten cases (3.25%) of congenital anomalies were seen. The most frequent congenital anomalies were artrogryposis, Amorphous globosus, and cleft palate (palatoschisis). Infectious causes were investigated, but only BVDV infection was detected by immunohistochemistry in one case, which was affected with porencephalia.

ABSTRACT.- Corrêa A.M.R., Bezerra P.S.J., Pavarini S.P., Santos A.S., Sonne L., Zlotowski P., Gomes G. & Driemeier D. 2008. Senecio brasiliensis (Asteraceae) poisoning in Murrah buffaloes in Rio Grande do Sul. Pesquisa Veterinária Brasileira 28(3):187-189. Departamento de Patologia Clínica Veterinária, Universidade Federal do Rio Grande do Sul, Av. Bento Gonçalves 9090, Porto Alegre, RS 91540-000, Brazil. E-mail: davetpat@ufrgs.br Thirteen (14.4%) out of 90 Murrah buffaloes (Bubalus bubalis) became ill after con-sumption of Senecio brasiliensis, and 11 (12.2%) of them died. The buffaloes were kept in a highly Senecio brasiliensis infested area. The poisoning occurred in June-August 2006 on a farm in the county of Nova Prata, Rio Grande do Sul, southern Brazil. Clinical signs included weakness, apathy, progressive weight loss, permanent decubitus, and diarrhea. Necropsy was performed in 2 of the 11 buffaloes that died. The pathological findings were typical of poisoning by pyrrolizidine alkaloids. High infestation of pastures with S. brasiliensis, severe drought, and consequent starvation were the main epidemiological factors associated with the poisoning here described.
