Parasitos gastrintestinais de suínos criados em sistema de produção de agricultura familiar no semiárido paraibano, nordeste do Brasil.

Abstract

A cross-sectional study was carried out to verify the prevalence of gastrointestinal parasites of pigs reared in a family farming system in the semiarid region of Paraíba, Northeast Brazil. In total, 187 pigs, of both sexes and different ages, were sampled from 51 properties. Samples were collected from feces of each animal, then counts of Eggs Per Grass (EPG) and Oocyst Per Grass (OoPG) feces were performed. Among the 187 samples evaluated, the total prevalence of gastrointestinal parasites was 79.6% (149/187). The most prevalent parasites were Coccidia (56.6%), followed by Estrongilidae (15.5%), Trichuris sp. (6.9%) and Ascaris sp. (0.64%). Fifty-five coprocultures were carried out with the samples positive for helminths in the OPG of these, 80% (44/55) were positive for Strongyloideae larvae, with the genera Oesophagostomum 56.8% (25/44), Strongyloides 43, 1% (19/44) and Hyostrongylus 18.1% (8/44), with mixed infection in 47.7% (21/44) of the samples. The presence of coccidia oocysts was detected in 56.6% (106/187) of the analyzed samples. Identification of the species was performed through morphometric analysis of oocysts and sporocysts. The most prevalent species was Eimeria suis com (21,89%), followed by Cystoisospora (16,63%), Eimeria neodebliecki (14,55%), Eimeria perminuta (12,71%), Eimeria polita(10,46%), Eimeria debliecki (10.43%), Eimeria porci (8.73%), Eimeria scabra (3.48%), Eimeria cerdonis (1.01%).
