Seroprevalence of Triatoma virus (Dicistroviridae Cripaviridae) antibodies in Chagas disease patients

Chagas disease is caused by Trypanosoma cruzi, and humans acquire the parasite by exposure to contaminated feces from hematophagous insect vectors known as triatomines. Triatoma virus (TrV) is the sole viral pathogen of triatomines, and is transmitted among insects through the fecal-oral route and, as it happens with T. cruzi, the infected insects release the […]

Immunoproteomic analysis of Plasmodium falciparum antigens using sera from patients with clinical history of imported malaria

The malaria caused by Plasmodium falciparum remains a serious public health problem in the world, due largely to the absence of an effective vaccine. There is a lack of information on the structural properties and antigens capable of activating the immunological mechanisms for the induction of protective immunity. Therefore, the objective of this study is to evaluate the serological reactivity of sera from individuals with imported malaria and identify major immunogenic proteins.

Prevalence and level of antibodies anti-plasmodium spp. in travellers with clinical history of imported malaria

In this study, we show that 40.29% of travellers with a possible history of malaria exposure were positive for anti-Plasmodium spp. antibodies, while these individuals were negative by microscopy. The antibody test described here is useful to elucidate malaria exposure in microscopy-negative travellers from endemic countries.
