Registro de vicuñas (Vicugna vicugna, Molina 1782) como hospedador de Amblyomma parvitarsum Neumann, 1901 (Acari: Ixodidae) en Bolivia

Adult stage Ixodidae mites were collected from wild vicuna (Vicugna vicugna Molina 1782), captured at threelocations from the Área Natural de Manejo Integrado Nacional Apolobamba, in the Department of La Paz, Bolivia.The collected ticks corresponded to the species Amblyomma parvitarsum (Neumann 1901). This paper constitutes thesecond report of A. parvitarsum in Bolivia and the first confirmed report for vicuna as definitive hosts in the Andeanregion of this country.Se recolectaron estadios adultos de ácaros Ixodidae de vicuñas silvestres (Vicugna vicugna, Molina 1782) capturadasen tres localizaciones del Área Natural de Manejo Integrado Nacional Apolobamba, en el Departamento de La Paz,Bolivia. Las garrapatas duras recolectadas correspondieron a la especie Amblyomma parvitarsum (Neumann, 1901).Este trabajo se constituye en el segundo reporte de A. parvitarsum en Bolivia y el primero que confirma a vicuñascomo hospedadores definitivos en la región Andina de este país

Estudio coproparasitario y ectoparasitario en alpacas (Vicugna pacos Linnaeus, 1758) de Apolobamba, con nuevos registros de Phthiraptera (Insecta) e Ixodidae (Acari), La Paz – Bolivia

Although parasites in South American camelids (SAC) can cause severe economic losses in Bolivia, a country with largepopulations of SAC, knowledge of these parasites in this species is limited. To obtain data on the parasitic fauna in alpacasfrom the Integrated Management Natural Area Apolobamba (ANMI Apolobamba), in February 2006 we evaluated 82 alpacas to determine the presence of ecto and endoparasites and investigate some biological and ecological drivers for the presenceand distribution of parasites. In 54 (98.2%) fecal samples were positive to coccidia parasitic forms, nematodes, cestodes andtrematodes. Significant prevalence (P<0.05) of nematodes of the order Strongylida and Capillaria spp. was found in adults and young alpacas respectively. From 82 individuals reviewed, 51 (62.2%) had infestations caused by Bovicola breviceps, Microthoracius mazzai, M. praelongiceps, M. minor, Amblyomma parvitarsum and Sarcoptes scabiei var. aucheniae, andsignificant prevalence (P <0.05) of lice M. praelongiceps was observed in females alpacas. This is the first registry of Bovicola breviceps in Bolivia, and the ectoparasites of Microthoracius mazzai, M. praelongiceps, M. minor and Amblyommaparvitarsum are the first records found in alpacas from Bolivia.Program, Wildlife Conservation Society, Calle Gabino Villanueva # 340 Calacoto.

El registro de Bovicola breviceps es nuevo para Bolivia, y los ectoparásitos Microthoracius mazzai, M.praelongiceps, M. minor y Amblyomma parvitarsum constituyen los primeros registros para alpacas en Bolivia

Colombian consensus recommendations for diagnosis, management and treatment of the infection by SARS-COV-2/ COVID-19 in health care facilities - Recommendations from expert´s group based and informed on evidence

La Asociación Colombiana de Infectología (ACIN) y el Instituto de Evaluación de Nuevas Tecnologías de la Salud (IETS) conformó un grupo de trabajo para desarrollar recomendaciones informadas y basadas en evidencia, por consenso de expertos para la atención, diagnóstico y manejo de casos de Covid 19. Estas guías son dirigidas al personal de salud y buscar dar recomendaciones en los ámbitos de la atención en salud de los casos de Covid-19, en el contexto nacional de Colombia

Record of vicunas (Vicugna vicugna Molina 1782) as host of Amblyomma parvitarsum Neumann 1901 (Acari: Ixodidae) in Bolivia

Adult stage Ixodidae mites were collected from wild vicuna (Vicugna vicugna Molina 1782), captured at three locations from the Área Natural de Manejo Integrado Nacional Apolobamba, in the Department of La Paz, Bolivia. The collected ticks corresponded to the species Amblyomma parvitarsum (Neumann 1901). This paper constitutes the second report of A. parvitarsum in Bolivia and the first confirmed report for vicuna as definitive hosts in the Andean region of this country

Molecular and serologic survey of pathogens in an endangered andean cat (Leopardus jacobita) of the high andes of Bolivia

The Andean cat (Leopardus jacobita) is one of the most threatened and least known wild felids in the world. Using molecular and serologic tests, we screened a free-ranging Andean cat for 17 pathogens of conservation concern. Results suggested no evidence of infection or exposure. Whether pathogens are a threat for Andean cat populations remains currently unknown

Amblyomma parvitarsum (Acari: Ixodidae): localities, hosts and host-parasite ecology

Only a few aspects of the biology of Amblyomma parvitarsum Neumann are known. Adults of this hard tick species are parasites of South American camelids in the Andean plateau of Argentina, Bolivia, Peru and Chile and also in the Argentine Patagonia, but they have been also rarely found on other artyodactils and two species of birds. The larva has been collected from reptiles in northern Chile, whereas the hosts for the nymph remain unknown. On nine localities included within Altitude Tropical and Perarid Mediterranean ecoregions in northern Chile, we analyzed 237 reptiles, 285 birds, 624 rodents and 52 camelids for infestation with A. parvitarsum to calculate seasonal prevalence of this tick. We also reviewed the literature of this tick and three entomological collections for obtaining and summarizing all the information to date about this tick. None of the analyzed birds and rodents were parasitized with A. parvitarsum; however, seven over a total of ten reptile species that we caught were infested with the larva. In the camelid species Lama glama and Vicugna pacos we collected adult specimens of this tick. Larval prevalence was higher during fall (75 %) in Liolaemus pleopholis in the Altitude Tropical ecoregion. We also collected adult specimens of A. parvitarsum from camelid manure heaps during summer in Salar de Surire and Llullaillaco localities. Additionally, we also reviewed the literature of this tick and examined specimens in three entomological collections for obtaining and summarizing all the information to date about this tick. By this study, nine localities and seven new hosts are added for A. parvitarsum and we confirm reptiles as specific hosts of this tick larva.Fil: Muñoz Leal, Sebastian.
