Preliminary evaluation on the efficiency of the kit Platelia Dengue NS1 Ag-ELISA to detect dengue virus in dried Aedes aegypti: a potential tool to improve dengue surveillance
Parasites & Vectors 2014, 7:155 (1 April 2014)
The commercial kit performed well in detecting dengue virus in dried Ae. aegypti
mosquitoes when compared with standard techniques such as virus isolation and
qRT-PCR. This finding may help improve dengue surveillance by searching virus in
wild mosquitos rather than in human patients. Image: Immunofluorescence of Ae. aegypti head tissues after dengue infection.
Ecology of Rhodnius robustus Larrousse, 1927 (Hemiptera, Reduviidae, Triatominae) in Attalea palm trees of the Tapajós River Region (Pará State, Brazilian Amazon)
Parasites & Vectors 2014, 7:154 (1 April 2014)
Rhodnius robustus is an important vector of Trypanosoma cruzi, the etiologic agent of Chagas disease in the Brazilian Amazon Region. In this study we address aspects of the ecology of this species in Attalea spp. palm trees. Picture: Rhodnius robustus collected in Attalea speciosa, Tapajos River Region, State of Para, Brazil.

Molecular phylogeny of Triatomini (Hemiptera: Reduviidae: Triatominae)
Parasites & Vectors 2014, 7:149 (31 March 2014)
Molecular phylogeny of Triatomini (Hemiptera: Reduviidae) confirms Triatoma and Panstrongylus paraphyletic status, and that Nesotriatoma and Mepraia should be ranked as genera, while Meccus status still remain to be further investigated. Image: Triatomini phylogeny and T. rubrofasciata, the subfamily type species.

TcI/TcII co-infection can enhance Trypanosoma cruzi growth in Rhodnius prolixus
Parasites & Vectors 2014, 7:94 (4 March 2014)
The growth behaviour of two Trypanosoma cruzi isolates in single and mixed infections was analyzed. The distribution of the parasites in different intestinal regions of Rhodnius prolixus was evaluated by microscopy and PCR. The differing growth in some intestinal regions in the mixed infection indicates a cooperative behaviour of the T. cruzi isolates. Image: Rhodnius prolixus 5th instar nymph, dorsal view.
In vivo imaging of mice infected with bioluminescent Trypanosoma cruzi unveils novel sites of infection
Parasites & Vectors 2014, 7:89 (3 March 2014)
Bioluminescent imaging brought, for the first time, new information about the progression and dynamic of infection, in real time, detecting new sites of infection such as the urogenital region which was maintained until the chronic phase. Image: In vivo bioluminescent images of mice infected for two weeks with 106 transgenic Dm28c-luc and ex vivo evaluation of amastigote nests (arrow) in the rectum/ anal region by histology.
