host-biting rate and susceptibility of some suspected vectors to leishmania braziliensis.american tegumentary leishmaniasis is a serious brazilian public health problem. this diseases is attributed to seven species of leishmania, however, the majority of cases are associated with leishmania braziliensis. some phlebotomine species have been implicated in the transmission of this parasite, nonetheless only psychodopygus wellcomei has had its vectorial competence demonstrated. thus this study sought to assess some parameters related to the vectorial capacity of anthropophilic species o ...201424684943
canine visceral leishmaniasis in the metropolitan area of são paulo: pintomyia fischeri as potential vector of leishmania infantum.american visceral leishmaniasis is a zoonosis caused by leishmania infantum and transmitted mainly by lutzomyia longipalpis. however, canine cases have been reported in the absence of this species in the greater são paulo region, where pintomyia fischeri and migonemyia migonei are the predominant species. this raises the suspicion that they could be acting as vectors. therefore, this study sought to investigate specific vector capacity parameters of these species and to compare them with those o ...201728134092
