Abstract

BELTRAN-SAAVEDRA, L. Fabián; GONZALEZ-ACUNA, Daniel; NALLAR-GUTIERREZ, Rodolfo  and  TICONA-CHALLCO, Herminio. Coproparasitologycal and ectoparasitologycal survey in alpaca (Vicugna pacos Linnaeus, 1758) from Apolobamba, with new records of Phthiraptera (Insecta) and Ixodidae (Acari), La Paz - Bolivia. J.Selva Andina Anim. Sci. [online]. 2014, vol.1, n.2, pp. 2-17. ISSN 2311-2581.

Although parasites in South American camelids (SAC) can cause severe economic losses in Bolivia, a country with large populations of SAC, knowledge of these parasites in this species is limited. To obtain data on the parasitic fauna in alpacas from 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 presence and distribution of parasites. In 54 (98.2%) fecal samples were positive to coccidia parasitic forms, nematodes, cestodes and trematodes. 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, and significant 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 Amblyomma parvitarsum are the first records found in alpacas from Bolivia.
