New hosts and localities for helminths of carnivores in Argentina

Abstract

A total of 111 samples (43 faeces and 79 gastrointestinal tracts) of 14 wild carnivore species from 12 Argentine provinces were analyzed. Helminth eggs were identified in 73% of the faecal samples and adult worms were recovered from 81% of the gastrointestinal tracts. We found 19 helminth species. Among the most frequent findings were parasites of domestic carnivores, namely Toxocara canis, Toxocara cati, Toxascaris leonina, Ancylostoma caninum, Ancylostoma tubaeforme and Uncinaria stenocephala. In addition, new hosts are reported for 6 nematode species and 5 helminth species are recorded for the first time in Argentina: Aonchotheca putorii, Molineus brachiurus, Cyathospirura chevreuxi, Physaloptera praeputialis and Oncicola martini.

Endoparasitic fauna of two South American foxes in Chile: Lycalopex culpaeus and Lycalopex griseus

“…The present study is so far the most complete survey for endoparasites in wild foxes in Chile, and provides with new data about the presence and distribution of these parasites, with nine new host records for Andean fox and two for Chilla fox in South America, and three new records for the country. Overall, the high prevalence of parasitic infection was similar to previous studies in wild canids from Europe (Shimalov & Shimalov, 2002, 2003Bružinskaitė-Schmidhalter et al, 2011;Al-Sabi et al, 2013) and South America (Ruas et al, 2008;Moleón et al, 2015).…”

“…In Chile there are three species of wild canids, Andean fox or Culpeo fox (Lycalopex culpaeus), Chilla fox (Lycalopex griseus) and Darwin's fox (Lycalopex fulvipes), which also faces several threats related to hunting by farmers, fragmentation of habitat, competition and transmission of diseases by domestic canids (Jiménez & Novaro, 2004). For South American wild canids, there is a fragmented knowledge regarding endoparasites (Moleón et al, 2015). In the particular case of Chile, most of the published parasitological records are related to ectoparasites such as fleas (Rubio et al, 2013;Poo-Muñoz et al, 2016), lice (Mey, 2003;González-Acuña et al, 2007), mites (Verdugo et al, 2016;Briceño et al, 2020) and ticks (González-Acuña & Guglielmone, 2005;Rubio et al, 2013).…”

Toxocariasis in Carnivora from Argentinean Patagonia: Species molecular identification, hosts, and geographical distribution

“…The first three are hosts for T. cati, but for the other species no parasite information is available. The previous known distribution of T. cati infections in cougar were recorded in Córdoba and Santa Cruz provinces, and in Geoffroy's cat in La Pampa, Buenos Aires, Entre Ríos, and Santa Fe provinces ( Beldoménico et al, 2005 ; Moleón et al, 2015 ). For the last host is the southernmost record of T. cati in South America.…”

“…In Americas, records of T. cati have been reported from wild carnivores include Chile ( González-Acuña et al, 2010 ), Bolivia ( Fiorello et al, 2006 ), Perú ( Aranda et al, 2013 ), Brazil ( Gallas and Fraga da Silveira, 2013 ), Belize ( Patton et al, 1986 ), México ( Solórzano-García et al, 2017 ), United States ( Ubelaker et al, 2014 ), and Canada ( Dare and Watkins, 2012 ). In Argentina, the findings of T. cati larvae and adults were recorded from digestive tracts of Leopardus geoffroyi D'Orbigny and Gervais 1844, Puma concolor Linneus 1771, and Leopardus guigna (Molina, 1782) ( Beldoménico et al, 2005 ; Moleón et al, 2015 ) from different localities of the country ( Table 1 ).…”

Helminth parasites of Galictis cuja (Carnivora, Mustelidae), from localities in the Atlantic forest of Brazil

“…Lunaschi & Drago (2007) and Fugassa (2015) did not mention any occurrences of helminths in this mammal in Argentina. However, Moleón et al (2015) provided the first report on occurrences of helminths in G. cuja in Argentina, consisting of the nematode Aonchotheca putorii (Rudolphi, 1819) (Trichocephalida, Capillariidae). In G. cuja from Paraguay, Seesee et al (in YENSEN & TARIFA, 2003) listed occurrences of unidentified nematode species of the genera Cruzia Travassos, 1917 (Spirurida, Kathlaniidae), Dirofilaria Railliet & Henry, 1910 (Spirurida, Onchocercidae), Gnathostoma Owen, 1836 (Spirurida, Gnathostomatidae), and Lagochilascaris Leiper, 1909 (Spirurida, Ascaridae), along with unidentified nematode species in the families Oxyuridae and Trichostrongylidae.…”
