Phylogenetic structure of geographical co‐occurrence among New World Triatominae species, vectors of Chagas disease

Journal of Biogeography, Volume 47, Issue 6, Page 1218-1231, June 2020., 2020
Abstract Aim The tropical niche conservatism (TNC) hypothesis is one of the most prominent evolutionary hypotheses that has been supported as an explanation for the diversity gradients of several animal taxa, mainly vertebrates. However, the validity of TNC for less‐known taxa such as disease vectors is not clear.

Trypanosomatid infections in captive wild mammals and potential vectors at the Brasilia Zoo, Federal District, Brazil

Veterinary Medicine and Science, Volume 6, Issue 2, Page 248-256, May 2020., 2020
Conservation projects in zoos require translocations of captive animals, which may spread pathogens. We aimed to verify the occurrence of vectors (triatomines and sandflies) and to investigate Trypanosoma cruzi and Leishmania infections in captive wild mammals in the Zoo Brasília.

Trypanosoma cruzi: Kinetics of metacyclogenesis in adult and nymphal Panstrongylus megistus [PDF]

Experimental Parasitology, 1985
Adult triatomine insects, Panstrongylus megistus, naturally infected with the protozoa, Trypanosoma cruzi, contained significantly more metacyclic trypomastigote forms in their digestive tracts than did P. megistus nymphs. Metacyclics were scarce in all stages of triatomines fed once on infected mammalian hosts and subsequently starved.

DmCatD, a cathepsin D-like peptidase of the hematophagous insect Dipetalogaster maxima (Hemiptera: Reduviidae): Purification, bioinformatic analyses and the significance of its interaction with lipophorin in the internalization by developing oocytes [PDF]

, 2018
DmCatD, a cathepsin D-like peptidase of the hematophagous insect Dipetalogaster maxima, is synthesized by the fat body and the ovary and functions as yolk protein precursor. Functionally, DmCatD is involved in vitellin proteolysis.
