Tissue Cytokine Responses in Canine Visceral Leishmaniasis [PDF]

, 2001
To elucidate the local tissue cytokine response of dogs infected with Leishmania chagasi, cytokine mRNA levels were measured in bone marrow aspirates from 27 naturally infected dogs from Brazil and were compared with those from 5 uninfected control ...

Putting Infection Dynamics at the Heart of Chagas Disease. [PDF]

, 2016
In chronic Trypanosoma cruzi infections, parasite burden is controlled by effective, but nonsterilising immune responses. Infected cells are difficult to detect because they are scarce and focally distributed in multiple sites.

Competence of non-human primates to transmit Leishmania infantum to the invertebrate vector Lutzomyia longipalpis.

PLoS Neglected Tropical Diseases, 2019
Leishmaniasis is a zoonotic disease of worldwide relevance. Visceral leishmaniasis is endemic in Brazil, where it is caused by Leishmania infantum with Lutzomyia longipalpis being the most important invertebrate vector. Non-human primates are susceptible

Skin parasite landscape determines host infectiousness in visceral leishmaniasis [PDF]

, 2017
Increasing evidence suggests that the infectiousness of patients for the sand fly vector of visceral leishmaniasis is linked to parasites found in the skin.

Xenodiagnóstico na Habronemose dos Equídeos: estudo das larvas do Helminto

Memorias do Instituto Oswaldo Cruz, 1945
Xenodiagnosis for habronemosis was 96,6% positive in 87 stud horses at Instituto Oswaldo Cuz, Rio de Janeiro, Brazil, from July-November, 1944. The A A. were unable to identify the Habronema larvae obtained from parasitider fly maggots.
