Résumé:
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%).
