| detection of a potential new bartonella species "candidatus bartonella rondoniensis" in human biting kissing bugs (reduviidae; triatominae). | among the reduviidae family, triatomines are giant blood-sucking bugs. they are well known in central and south america where they transmit trypanosoma cruzi to mammals, including humans, through their feces. this parasitic protozoan is the causative agent of chagas disease, a major public health issue in endemic areas. because of the medical and economic impact of chagas disease, the presence of other arthropod-borne pathogens in triatomines was rarely investigated. | 2017 | 28095503 |
| human trypanosomiasis in the eastern plains of colombia: new transmission scenario. | characteristics of trypanosoma cruzi infection were studied in a rural area of the eastern plains of colombia. using enzyme-linked immunosorbent assay and indirect fluorescent-antibody tests, the infection was determined in 11.6% of the inhabitants of 142 dwellings. during 6 months of community surveillance, in 42.3% dwellings, 609 triatomines were collected (597 rhodnius prolixus and seven, three, one, and one of panstrongylus geniculatus, psammolestes arturi, eratyrus mucronatus, and triatoma ... | 2016 | 26728765 |
| amazonian triatomine biodiversity and the transmission of chagas disease in french guiana: in medio stat sanitas. | the effects of biodiversity on the transmission of infectious diseases now stand as a cornerstone of many public health policies. the upper amazonia and guyana shield are hot-spots of biodiversity that offer genuine opportunities to explore the relationship between the risk of transmission of chagas disease and the diversity of its triatomine vectors. over 730 triatomines were light-trapped in four geomorphological landscapes shaping french-guiana, and we determined their taxonomic status and in ... | 2016 | 26867025 |
| on triatomines, cockroaches and haemolymphagy under laboratory conditions: new discoveries. | for a long time, haematophagy was considered an obligate condition for triatomines (hemiptera: reduviidae) to complete their life cycle. today, the ability to use haemolymphagy is suggested to represent an important survival strategy for some species, especially those in genus belminus. as eratyrus mucronatus and triatoma boliviana are found with cockroaches in the blaberinae subfamily in bolivia, their developmental cycle from egg to adult under a "cockroach diet" was studied. the results sugge ... | 2016 | 27706376 |
