Heme crystallization in the midgut of triatomine insects [PDF]

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2007
Hemozoin (Hz) is a heme crystal produced by several blood-feeding organisms in order to detoxify free heme released upon hemoglobin (Hb) digestion. Here we show that heme crystallization also occurs in three species of triatomine insects. Ultraviolet-visible and infrared light absorption spectra of insoluble pigments isolated from the midgut of three ...

Screening for Trypanosoma cruzi infection (Chagas disease) in the Latin American population living with HIV in London

HIV Medicine, EarlyView.
Abstract Background There are an estimated 2482 people born in Latin American countries receiving care for HIV in the United Kingdom. Although national guidance recommends screening for Trypanosoma cruzi infection (Chagas disease) in this population, there is no formal screening programme.

Trypanosoma cruzi Parasite Burdens of Several Triatomine Species in Colombia

Tropical Medicine and Infectious Disease, 2022
Trypanosoma cruzi, the causal agent of Chagas disease, is mainly transmitted by insects of the Triatominae subfamily. In Colombia, there are 26 triatomine species, and 16 of them are naturally infected with the parasite.

Activity of the prophenoloxidase system and survival of triatomines infected with different Trypanosoma cruzi strains under different temperatures: understanding Chagas disease in the face of climate change

Parasites & Vectors, 2019
Little is known about how human disease vectors will modify their life history patterns and survival capacity as a result of climate change. One case is that of Chagas disease, which has triatomine bugs and Trypanosoma cruzi as vectors and parasite ...

In Vitro Impact of Triatomine Salivary Glands Extracts Introduced to Endothelial Cells [PDF]

, 2018
Chagas Disease (AKA Trypanosomiasis) is caused by biting/feeding behavior from the arthropod vector Triatoma (subfamily of Reduviidae family), that house the endoparasite Trypanosoma cruzi, which can then be passed to human and mammalian hosts (Schmidt ...

Exploiting triatomine behaviour: alternative perspectives for their control [PDF]

Memórias do Instituto Oswaldo Cruz, 2009
Living in close association with a vertebrate host and feeding on its blood requires different types of adaptations, including behavioural adjustments. Triatomines exhibit particular traits associated with the exploitation of their habitat and food sources and these traits have been the subject of intense analysis.

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

Journal of Applied Entomology, EarlyView.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

Temporal and Spatial Patterns of Mating in Rhodnius prolixus

Insects
The kissing bug Rhodnius prolixus is a nocturnal species; however, its temporal mating patterns remain unexplored. Copulation lasts about fifty minutes, during which time the couple remains almost motionless. We hypothesized that R.
