Tunga penetrans causes tungiasis, a parasitic disease of humans and domestic animals. In this work we report the presence of tungiasis in the southern tamandua (Tamandua tetradactyla) from Formosa, Argentina. An individual of southern tamandua was found dead on the roadside and it presented lesions consisted with neosomes located on its four limbs.

Patagonia is inhabited by two armadillo species, Chaetophractus villosus and Zaedyus pichiy. In this study we describe and analyze the variation on helminth fauna of these armadillos in Patagonia compared with northern localities described in previous studies.

These three ecoregions are visibly distinguishable from an edaphological and phytogeographic point of view, while the mammalian fauna composition is homogeneous.

Fleas were collected from 218 pichis in southern Mendoza, Argentina, in summer and winter of 2015 and 2016. Prevalences were analyzed and differences in the intensities of the total number of fleas related to host (age, sex, weight, size and physical condition) and environment-related (seasonality and year) factors evaluated.

This study revealed the presence of 3 species of the genus Akumyan, 1946 (Cestoda Anoplocephalidae), two of them new for science. These species are described, illustrated, and compared with related species.

An isolated population is located in the east of the Buenos Aires province, separated from the population of central Argentina by about 500 km. We compared the component community of between the main population in central Argentina and the isolated population, evaluating the impact of the host isolation on parasite diversity.

Fleas and domestic pigs (Sus scrofa Linnaeus, 1758) are a known association. However, knowledge about fleas on pigs in Argentina is scarce.

Tunga penetrans (Siphonaptera, Tungidae) is a flea that infests humans and a variety of domestic and wild animals. Burrowing of the female flea under the skin causes tungiasis, a disease that manifests in skin lesions that if untreated, can progress to severe complications. In this paper, we report the first case of T.

In this work, a new species, Pterygodermatites ( Paucipectines) argentinensis, is described, and new morphometric data, new host records, and the geographical distribution of Pterygodermatites ( Paucipectines) chaetophracti are provided. We examined 109 hosts belonging to Chaetophractus vellerosus, Chaetophractus villosus, Cabassous chacoensis, Dasypus hybridus, Tolypeutes matacus, and Zaedyus pichiy, from several regions of Argentina.

We interpret that fleas corresponding to the genus Tunga (Siphonaptera) produced these marks. These parasites locate in the carapace of the host, perforating the osteoderms by mechanical and chemical processes as the neosome grows.
