Gastrintestinal helminths of capybara (Hydrochoerus hydrochaeris) from the Paiaguás subregion, in the floodplain of Mato Grosso do Sul, Brazil / Helmintos gastrintestinais de capivaras (Hydrochoerus hydrochaeris) na sub-região de Paiaguás, Pantanal do Mato Grosso do Sul, Brasil

ABSTRACT

Six nematode, three cestode and five trematode species were identified in 30 capybara specimens (Hydrochoerus hydrochaeris hydrochaeris L., 1766). The species of greater prevalence were Protozoophaga obesa (96.66%), Viannella hydrochoeri (93.33%), Hydrochoerisnema anomalobursata (90.0%), F.I. P. obesa (80.0%), Taxorchis schistocotyle (76.66%), Hippocrepis hippocrepis (70.0%), Capillaria hydrochoeri (63.33%), F.I. (Viannella + Hydrochoerisnema) (60.0%), Strongyloides chapini (56.66%), Monoecocestus macrobursatum (56.66%), F.I. Monoecocestus (46.66%), M. hydrochoeri (23.33%) and M. hagmani (23.33%). On the other hand, Trichostrongylus axei, Neocotyle neocotyle, Nudacotyle valdevaginatus and N. tertius occurred at lower levels. The total of helminths identified in the 30 animals was of 236,097 being verified 110 (0.05%) specimens in the stomach, 49,240 (20.85%) in the small intestines, 186,747 (79.10%) in the large intestines. The higher intensity variation were obtained by P. obesa, F.I. P. obesa, F.I. (Viannella + Hydrochoerisnema); V. hydrochoeri, S. chapini e N. valdevaginatus, with a mean of 3,900.0 (04-20,885), 2,958.1 (40-18,130), 689.7 (05-7,515), 601.5 (10-4,585), 765.3 (05-4,055) and 1,270.0 (0-1,270) worms per animal, respectively. V. hydrochoeri and S. chapini are the most pathogenic species, with clinical and subclinical parasitosis in capybara.

RESUMO

Em trinta espécimes de capivaras (Hydrochoerus hydrochaeris hydrochaeris L., 1766) foram identificadas seis espécies de nematódeos, três de cestódeos e cinco de trematódeos. As espécies de maior prevalência foram Protozoophaga obesa (96,66%), Viannella hydrochoeri (93,33%), Hydrochoerisnema anomalobursata (90,0%), F.I. P. obesa (80,0%), Taxorchis schistocotyle (76,66%), Hippocrepis hippocrepis (70,0%), Capillaria hydrochoeri (63,33%), F.I. (Viannella + Hydrochoerisnema) (60,0%), Strongyloides chapini (56,66%), Monoecocestus macrobursatum (56,66%), F.I. Monoecocestus (46,66%), M. hydrochoeri (23,33%) e M. hagmanni (23,33%). Por outro lado, Trichostrongylus axei, Neocotyle neocotyle, Nudacotyle valdevaginatus e N. tertius ocorreram em níveis mais baixos. O total de helmintos identificados nas trinta capivaras foi de 236.097, sendo constatado 110 (0,05%) exemplares nos estômagos, 49.240 (20,85%) nos intestinos delgados e, 186.747 (79,10%) nos intestinos grossos. As maiores variações de intensidade foram obtidas por P. obesa, F.I. P. obesa, F.I. (Viannella + Hydrochoerisnema); V. hydrochoeri, S. chapini e N. valdevaginatus com média de 3.900,0 (04-20885), 2.958,1 (40-18130), 689,7 (05-7515), 601,5 (10-4585), 765,3 (05-4055) e 1.270,0 (0-1270) helmintos por animal, respectivamente. V. hydrochoeri e S. chapini são as espécies mais patogênicas, com parasitoses clínicas e subclínicas
