Se reporta la presencia del ácaro Amblyomma calcaratum colectado en un ejemplar de un mirmecofagido Tamandua tetradactyla, capturado en julio del 2000 en la localidad de Bagua Grande, Amazonas , Perú. Se mencionan las relaciones filogenéticas de esta especie con A. nodosum y de su importancia médica.

Bartonellosis and rickettsiosis are commonly reported in Peru. In order to detect Bartonella sp. and Rickettsiasp. in fleas, ticks and lice, specimens from five distinct locations in Peru (Marizagua, Cajaruro, Jamalca, Lonya Grande and El Milagro) were collected and screened for the presence of these bacteria using PCR and later confirmation by DNA sequencing. The specimens collected were distributed in 102 pools (76 Ctenocephalides felis, 2 Ctenocephalides canis, 16 Pulex irritans, 5 Pediculus humanus, 2 Rhiphicephalus sanguineus, and 1 Boophilus spp.), where Bartonellawas detected in 17 pools (6 of C. felis, 9 of P. irritans, 1 of C. canis, and 1 P. humanus). Also, Rickettsiawas detected in 76 pools (62 C. felis, 10 P. irritans, 2 P. humanus, and 2 C. canis). Bartonella clarridgeiaewas detected in C. felis, C. canisand P. irritanspools at 5.3%, 50% and 12.5%, respectively.Bartonella ro...

One hundred and twenty species had been reported up to 1999 and the following 11 are now added to Peruvian phlebotomine fauna: Brumptomyia quimperi, Evandromyia sallesi, Lutzomyia fispaili, L. scorzai, L. watsi, Micropygomyia longipennis, Trichophoromyia howardi, T. arevaloi, Trichopygomyia turelli, Warileya euniceae and W. leponti. A complete list of species in Huanuco, Pasco and Cusco departments is included and new records for Ayacucho, Amazonas, Cajamarca, Huancavelica, Junin, La Libertad, Loreto and San Martin are given. There appears to be epidemiological evidences of some phlebotomines of the subgenera Helcocyrtomyia and Pifanomyia as likely vectors of dermal leishmaniosis and Carrion's disease.

ntroduction: There is little and not recent information on the presence of triatomine bugs in San Martin department, Amazon area of our country where Chagas disease has been reported by wild triatomine insects as vectors. Objectives: To determine the geographic distribution of hematophagous triatomine insects in Huallaga and Picota provinces, San Martin department, Peru. To determine the domiciliary infestation by triatomine vectors indexes, trypano-triatomine infection as well as their dispersion. To determine the insects feeding source and to genetically characterize the tripanosomatidae they carry. Design: Observational and descriptive study. Setting: Health and Laboratories region networks. National Institute of Health laboratories. Participants: Houses from 6 districts of Huallaga province and 9 from Picota province (San Martin department). Interventions: Triatomine insect’s colle...

A las 120 especies de flebotomíneos reportadas hasta 1999 para el Perú, se adiciona: Brumptomyia quimperi, Evandromyia sallesi, Lutzomyia scorsai, L. rispaili, L. wattsi, Micropygomyia longipennis, Trichophoromyia howardi, T. arevaloi, Trichopygomyia turelli, W. euniceae y W leponti, incrementando a 131 especies el número de flebotomíneos. Se da a conocer la distribución geográfica de flebotomíneos en los departamentos de Huánuco, Pasco y Cusco; además, se destaca nuevos reportes de flebotomíneos en los departamentos de Ayacucho, Amazonas, Cajamarca, Huancavelica, Junín, La Libertad, Loreto y San Martín. Así mismo, se presentan evidencias epidemiológicas de algunos flebotomineos de los subgéneros Helcocyrtomyia y Pifanomyia como probables vectores de agentes patógenos de la leishmaniosis tegumentaria y de la enfermedad de Carrión (verruga peruana).
