Abstract

BackgroundChagas¿ disease is caused by the protozoan Trypanosoma cruzi and is autochthonous to the Americas. Its distribution depends on triatomine bugs that are responsible for the transmission of the disease. In 2005, we reported the presence and anthropophilic behavior of Panstrongylus geniculatus as a risk for Chagas¿ disease transmission in Caracas and neighboring areas. Three massive oral outbreaks occurred in the following years. Here we report the results of a 7-year study on triatomine species found in the Metropolitan District of Caracas (MDC), Venezuela.MethodsTriatomine species collected by inhabitants of Caracas from January 2007 to December 2013 were analyzed for parasite infection and evidence of a blood meal. Triatomines were found in 31 of the 32 parishes surveyed, distributed among 5 municipalities. The triatomines captured were identified to species and, where possible, examined for the presence of blood and parasites in the digestive tract. Parasitological and molecular techniques were used for species identification and typing of parasites.ResultsA total of 3551 triatomines were captured from 31 of the 32 parishes surveyed. The vast majority of these were identified as P. geniculatus (98.96%), followed by Triatoma nigromaculata (0.59%), Triatoma maculata (0.39%) and Rhodnius prolixus (0.06%). Triatomines were always most abundant between April and June, and 2010 saw the highest number of insects collected. We found that 54% of the specimens were females, 42.5% males and 3.5% nymphs. Overall, 75.2% of the insects were naturally infected with T. cruzi and 48.7% had fed on blood. Analysis of the adult forms showed that 60% of the females and 31.9% of the males had blood in their stomachs, and 77.5% of the females and 73.3% of the males were naturally infected with T. cruzi. Nearly all, 99.6% of the T. cruzi isolates analyzed belonged to the TcI genotype.ConclusionsBlood-fed triatomine bugs infected with T. cruzi were distributed throughout Caracas. Four different species of triatomines were identified of which P. geniculatus was by far the most predominant. Our previous report of Eratyrus mucronatus raises the number of triatomine species in the MDC to 5. Dramatic modifications to the surrounding natural habitats have led to the establishment of a T. cruzi urban enzootic cycle, resulting in a high risk for Chagas¿ disease transmission in this capital city.

Attention Score in Context

This research output has an Altmetric Attention Score of 12. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 May 2021.
All research outputs
#2,247,215
of 19,486,479 outputs
Outputs from Parasites & Vectors
#466
of 4,938 outputs
Outputs of similar age
#36,556
of 308,795 outputs
Outputs of similar age from Parasites & Vectors
#7
of 78 outputs
Altmetric has tracked 19,486,479 research outputs across all sources so far. Compared to these this one has done well and is in the 88th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,938 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.1. This one has done particularly well, scoring higher than 90% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 308,795 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 88% of its contemporaries.
We're also able to compare this research output to 78 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 92% of its contemporaries.
