laboratory tests performed on leishmania seroreactive dogs euthanized by the leishmaniasis control program.in 2008, in the west zone of rio de janeiro municipality-brazil, the leishmaniasis control program identified 155 dogs with titers = 40 by indirect immunofluorescence (iif) on blood collected onto filter paper. the objective of this study was to describe the laboratory test findings performed in dogs euthanized by the leishmaniasis program control of rio de janeiro municipality. dogs were examined, subjected to euthanasia and collection of clinical specimens. parasite isolation was obtained in 2 ...201121349644

trypanosoma caninum n. sp. (protozoa: kinetoplastida) isolated from intact skin of a domestic dog ( canis familiaris) captured in rio de janeiro, brazil.an unknown trypanosoma species was isolated from an axenic culture of intact skin from a domestic dog captured in rio de janeiro, brazil, which was co-infected with leishmania (viannia) braziliensis. giemsa-stained smears of cultures grown in different media revealed the presence of epimastigotes, trypomastigotes, spheromastigotes, transitional stages, and dividing forms (epimastigotes or spheromastigotes). the highest frequency of trypomastigotes was observed in rpmi (15.2%) and dmem (9.2%) med ...200919216827
