Sobre o encontro de Cavernícola pilosa Barber, 1937, no Estado do Paraná, Brasil

“…This species has already been reported in Brazil in the states of Pará, Tocantins, Bahia, Espírito Santo, Goiás, Mato Grosso do Sul, Minas Gerais, Paraná, and Maranhão (Lent and Jurberg 1969;Galvão et al 2003;Oliveira et al 2007Oliveira et al , 2008Gil-Santana et al 2014). A previous erroneous occurrence of this species in the state of Amazonas was cited by Gomes and Pereira (1977), who attributed this distribution to Neiva and Lent (1941). We read the entire paper and did not find this distribution cited in the text.…”

“…Another triatomine, Panstrongylus geniculatus Latreille, 1811, was found infected with Trypanosoma cruzi Chagas, 1909 in Cueva del Guano, a cave in Paraguaná Peninsula, Venezuela (Molinari et al 2007). Cavernicola pilosa is found associated with bats inhabiting caves or tree cavities in tropical regions, and there are reports of C. pilosa in human dwellings, where it is always associated with bats (Marinkelle 1966;Gomes and Pereira 1977;Lent and Wygodzinsky 1979;Oliveira et al 2008). Novo Aripuanã, Amazonas, presents a different ecological context, as it is in contact with the Floresta Nacional do Aripuanã and Reserva biológica do Manicoré, which put sylvatic populations of C. pilosa, a potential vector of Chagas disease, in close proximity to the human population.…”

Cavernicola pilosa Barber, 1937 is a wild triatomine species that generally lives in caves but has been found invading dwellings. It feeds mostly on bat blood. This vector has a wide geographical distribution throughout Central and South America, including Brazil, Ecuador, Colombia, French Guiana, Panamá, Peru, and Venezuela. In Brazil, C. pilosa occurs in the states of Bahia, Pará, Tocantins, Espírito Santo, Goiás, Mato Grosso do Sul, Minas Gerais, Paraná, and Maranhão. We report for the first time its presence in Amazonas state, Brazil.

Bats, Trypanosomes, and Triatomines in Ecuador: New Insights into the Diversity, Transmission, and Origins of Trypanosoma cruzi and Chagas Disease

et al. 2015

The generalist parasite Trypanosoma cruzi has two phylogenetic lineages associated almost exclusively with bats—Trypanosoma cruzi Tcbat and the subspecies T. c. marinkellei. We present new information on the genetic variation, geographic distribution, host associations, and potential vectors of these lineages. We conducted field surveys of bats and triatomines in southern Ecuador, a country endemic for Chagas disease, and screened for trypanosomes by microscopy and PCR. We identified parasites at species and genotype levels through phylogenetic approaches based on 18S ribosomal RNA (18S rRNA) and cytochrome b (cytb) genes and conducted a comparison of nucleotide diversity of the cytb gene. We document for the first time T. cruzi Tcbat and T. c. marinkellei in Ecuador, expanding their distribution in South America to the western side of the Andes. In addition, we found the triatomines Cavernicola pilosa and Triatoma dispar sharing shelters with bats. The comparisons of nucleotide diversity revealed a higher diversity for T. c. marinkellei than any of the T. c. cruzi genotypes associated with Chagas disease. Findings from this study increased both the number of host species and known geographical ranges of both parasites and suggest potential vectors for these two trypanosomes associated with bats in rural areas of southern Ecuador. The higher nucleotide diversity of T. c. marinkellei supports a long evolutionary relationship between T. cruzi and bats, implying that bats are the original hosts of this important parasite.
