New records of Leptospira spp. in wild marsupials and a rodent in the eastern Brazilian Amazon through PCR detection

ABSTRACT We analyzed the presence of Leptospira spp. in liver and kidney tissue of wild marsupials and rodents trapped in a periurban forest in the eastern Brazilian Amazon. We examined 25 individuals of four marsupial and seven rodent species for the presence of the 16S rRNA gene of Leptospira in t...

Zusammenfassung:ABSTRACT We analyzed the presence of Leptospira spp. in liver and kidney tissue of wild marsupials and rodents trapped in a periurban forest in the eastern Brazilian Amazon. We examined 25 individuals of four marsupial and seven rodent species for the presence of the 16S rRNA gene of Leptospira in the DNA extracted from 47 liver and kidney tissue samples using PCR. We detected positive samples in 12% (3/25) of the individuals, in kidney fragments of two marsupial species (Didelphis marsupialis and Marmosops pinheiroi) and in a liver fragment of one rodent species (Echimys chrysurus). These are the first records of Leptospira spp. in M. pinheiroi and E. chrysurus and it is the first molecular survey of marsupials and rodents in the Brazilian Amazon. RESUMO Analisamos a presença de Leptospira spp. em tecido hepático e renal de marsupiais e roedores silvestres capturados em uma floresta periurbana no leste da Amazônia brasileira. Foram examinados 25 indivíduos de quatro espécies de marsupial e sete de roedor quanto à presença do gene 16S rRNA de Leptospira no DNA extraído de 47 amostras de tecido hepático e renal usando PCR. Detectamos amostras positivas em 12% (3/25) dos indivíduos, em fragmentos renais de duas espécies de marsupial (Didelphis marsupialis e Marmosops pinheiroi) e em um fragmento hepático de uma espécie de roedor (Echimys chrysurus). Estes são os primeiros registros de Leptospira spp. em M. pinheiroi e E. chrysurus, e é o primeiro levantamento molecular de marsupiais e roedores na Amazônia brasileira.
