“…All the gastrointestinal parasites identified in our study had been documented in capybaras from various Neotropical regions (Alves and de Freitas 2022; Salas and Herrera 2004;Uribe et al 2021;Casas et al 1995;Sinkoc et al 2004Sinkoc et al , 2009Santos et al 2011, among others). In Argentina specifically, several parasite species have been recorded, including nematodes like Vianella hydrochoeri, Hydrocherisnema anomalobursata, Trichostrongylus cf axei, Strongyloides Alves and de Freitas 2022, among others).…”

Knowledge about parasitic diseases of wildlife will help us to understand the dynamics of parasites and their effects on host populations. The capybara (Hydrochoerus hydrochaeris) is the largest living rodent in the world, and its distribution is associated with the presence of tropical and subtropical wetlands in South America. The Los Padres Lake Integral Reserve (LPLIR) is an important conservation zone in the pampean region of Argentina. One of the emblematic species found within the reserve is the capybara. The objective of this study was to determine the gastrointestinal parasites present in wild capybaras of the LPLIR and to compare different coprological methodologies. Free-ranging capybara fresh feces from 57 individuals were randomly collected from the area of LPLIR in the summer of 2022. Three different techniques were applied: spontaneous sedimentation technique (SS), INTA modified McMaster technique (MM), and Mini-FLOTAC (MF) technique. Fifty-six samples from all samples analysed (56/57, 98%) were found to be positive for gastrointestinal parasites. Two species of Strongylida, Protozoophaga obesa, Echinocoleus hydrochaeris, one unidentified nematode, one unidentified spirurid, and at least two morphotypes of Eimeria spp. oocysts were recorded. There were found significant differences in the proportion of positive samples and in richness by technique, but no significant differences were found in parasite counting. In conclusion, the choice of methodology depends on the specific objectives of the study. This is the first parasitological study of capybaras from the LPLIR and represents an exploration of parasite communities present in these wild rodents at their southernmost distribution.

“…In the particular case of Misiones Province, information on tick species is scarce. So far the species recorded for Misiones are Amblyomma aureolatum (Pallas, 1772), Amblyomma calcaratum Neumann, 1899, Amblyomma incisum Neumann, 1906, Amblyomma longirostre (Koch, 1844, Amblyomma tigrinum Koch, 1844, Ixodes loricatus Neumann, 1899, Rhipicephalus microplus (Canestrini, 1888, Amblyomma ovale Koch, 1844, Amblyomma dubitatum Neumann, 1899, Rhipicephalus sanguineus sensu lato and Amblyomma brasiliense Aragão, 1908 (Boero 1957;Boero & Delpietro 1971;Guglielmone & Mangold 1984;Ivancovich & Luciani 1992;Sinkoc et al 1998;Mastropaolo et al 2004;Nava et al 2012;Welschen et al 2014).…”

Information on distribution and hosts of hard ticks of northern Misiones Province in Argentina is presented in this study. Ticks were identified by morphological characters and by sequences of a 410 bp fragment of the mitochondrial 16S rRNA gene. A total of 292 ticks collected from the environment and wild and domestic mammals were identified: Amblyomma coelebs, A. brasiliense, A. dubitatum, A. incisum, A. ovale, Haemaphysalis juxtakochi and Rhipicephalus microplus. The presence of A. coelebs was confirmed for Argentina and the first record of H. juxtakochi in Misiones was presented. Some of the species as A. incisum, A. ovale and R. microplus are ticks of medical and veterinary importance. Therefore, further studies on the vectorial role of these species in Misiones Province are necessary to determine their epidemiological relevance.
