Summary: Foi realizado um levantamento da infecção por Leptospira spp. em mamíferos silvestres do Pantanal sul-matogrossense com o emprego da reação de soroaglutinação microscópica (SAM) e da reação em cadeia da polimerase (PCR). Os sorovares de maior frequência nos animais investigados foram Hardjobovis (28%), Icterohemorhagiae (12%), M-110/2006 (isolado de Cerdocyon thous; 16%), Canicola (L014 isolada de Bos taurus, 4%), Whitcombi (4%), Pomona (20%), Autumnalis (12%) e Copenhageni (M9/99 isolada de Rattus norvegicus, 4%). Das 79 amostras examinadas pela PCR, 21 (26,58%) foram positivas, com a amplificação de um fragmento de aproximadamente 331pb. Dois fragmentos amplificados obtidos de amostras de C. thous foram clonados, sequenciados e identificados como L. interrogans por análise filogenética. A survey of Leptospira spp. in wild mammals from the southern Pantanal of Mato Grosso do Sul was performed by microscopic agglutination test (MAT) and polymerase chain reaction (PCR). The serovars most frequently found were Hardjobovis (28%), Icterohemorhagiae (12%), M110/2006 strain (isolated from Cerdocyon thous, 16%), Canicola (L014 isolated from Bos Taurus, 4%), Whitcombi (4%), Pomona (20%), Autumnalis (12%) and Copenhageni (M9/99 isolated from Rattus norvegicus, 4%). From the 79 samples tested by PCR, 21 (26.58%) were positive, resulting in the amplification fragment of approximately 331pb. Two amplified fragments from C. thous were cloned, sequenced and identified as L. interrogans by phylogenetic analysis.
