Abstract：
:The small mammal fauna of coffee plantations in SW Colombia was surveyed to determine which of the species present were infected with parasites of the Leishmania (Viannia) braziliensis complex and might therefore act as reservoirs of human cutaneous leishmaniasis. Fifty animals of seven different species were captured. Tissue samples were taken from the ears of specimens from each of the seven species. Thirty three samples were analysed by polymerase chain reaction (PCR) using oligonucleotide primers directed against conserved regions of L. (V) braziliensis complex kinetoplast DNA. Three of the samples (two from mouse opossums Micoureus demerarae, and one from a pygmy rice at Microryzomys minutus) gave positive results based on PCR analysis. When the samples were subjected to DNA hybridization (dot blot) analysis using the B18 (L. (V.) braziliensis complex-specific) probe, a total of ten specimens belonging to six species (the opossums M. demerarae and Didelphis marsupilalis, the rodents Melanomys caliginosus, Mi. minutus and Rattus rattus, and a rabbit Sylvilagus brasiliensis) gave positive results, indicating that all these animals had flies of species occurring in the same habitat by allowing them to feed on infected animals.
