Prevalencia de triatominos infectados con Trypanosoma cruzi en el litoral de la ciudad de Arica

An entomological and seroepidemiological study of the vectorial‐transmission risk of Chagas disease in the coast of northern Chile

“…The infection on the captured specimens reached 5.8% (3/52 specimens analysed). These values are lower than those reported by Carvajal et al (2007) and Botto-Mahan et al (2008) for this species and those found by Toledo et al (2013) in the same sampled sections; although the differences in infection found by Toledo et al (2013) could be explained by the fact that most of our specimens collected in San Marcos were associated with birds, in which the parasite does not reproduce owing to the mechanism of natural resistance to the parasite (Kierszenbaum et al, 1976).…”

“…These values are lower than those reported by Carvajal et al . () and Botto‐Mahan et al . () for this species and those found by Toledo et al .…”

“…This value could be explained by the low prevalence of the parasite in the insect vectors found in this study (5.8%). Previous studies reported variables infection rates of M. gajardoi between 11 and 27% in different localities of Region XV and Region I (Carvajal et al ., ; Botto‐Mahan et al, ; Jercic et al ., ; Toledo et al ., ). These rates are lower than those found in M. spinolai .…”

A new species and karyotype variation in the bordering distribution of Mepraia spinolai (Porter) and Mepraia gajardoi Frías et al (Hemiptera: Reduviidae: Triatominae) in chile and its parapatric model of speciation

“…Morphological and cytogenetic data indicated that the populations that border the distributions of M. gajardoi and M. spinolai, belong to a different species of parapatric origin. (Sagua et al 2000, Canals et al 2001, Carvajal et al 2007, Botto-Mahan et al 2008. This disease is important in the Neotropical region with nearly 16 million people infected, and another 90 million at risk of contracting the disease, especially in rural areas (Schofi eld et al 1982, Schofi eld 1994.…”

Congenital Trypanosoma cruzi Infection in Neonates and Infants from Two Regions of Chile Where Chagas' Disease Is Endemic

“…Three species of Reduviidae insect are transmitters of Chagas' disease to mammals, including humans, in Chile: Triatoma infestans, Triatoma spinolai, and Mepraia gajardoi (3,13). Modes of transmission of Chagas' disease other than infections through insect vectors have been documented to occur in Chile, including accidental laboratory infections, infections caused by blood transfusion, and transplacental infections.…”
