The principal reservoir host of cutaneous leishmaniasis in the urban areas of Manaus, Central Amazon of Brazil

[摘要] Twenty one opossums (Didelphis marsupialis) from disturbed primary forest in the vicinity of Manaus, and seven from an isolated island of secondary vegetation within the city of Manaus, were examined for the presence of Leishmania. Of the opossums from the primary forests, 13 (61.9%) were found to be positive for Leishmania braziliensis guyanenesis. One additional opossum was found to be positive for Le. mexicana amazonensis. A simple and economical trapping technique for opossums is presented here, and a control method in special cases is suggested.
