Resumo
This study evaluated the prevalence and counting
parasitism of different species of helminths of sheep from the microregion
of Jaboticabal of São Paulo state. For this, 66 animals
naturally infected, four to 36 months of age, raised in pasture,
were selected. The results of necropsy revealed the presence
of seven genera and 12 species with the following prevalence
and mean count: Haemonchus contortus: 100.0% (2947.2);
Trichostrongylus colubriformis: 90.9% (3048.8); Cooperia
curticei: 56.0% (256.5); Oesophagostomum columbianum:
48.4% (36.0); Cooperia punctata: 30.3% (94.5); Trichostrongylus
axei: 22.7% (26.5); Strongyloides papillosus: 19.6% (83.0),
Haemonchus contortus (L4): 7.5% (17.2), Cooperia pectinata:
10.6% (12.9), Trichuris ovis: 10.6 % (0.6); Cooperia spatulata
4.5% (0.3); Capillaria bovis: 4.5% (0.1). The mean parasitism of
helminthswas 6524.7 per animal. Haemonchus contortus (adults
and L4) and Trichostrongylus colubriformis corresponded to
45.4% and 46.7% of the average worm burden totally, respectively.
Based in the results obtained in this study, can be concluded that
the two most abundant species of helminths and important, the
micro-region of Jaboticabal are Trichostrongylus colubriformis
and Haemonchus contortus, and these two species amounted
to 92.1% of the distribution percentage of helminths collected
from all animals. These results demonstrate the importance of
conducting a counts of eggs per gram of feces (EPG) in the herds
of this region when FAMACHA is used on a particular property,
since this method control does not allow to diagnostic the damage/
clinical signs in animals infected by T. colubriformis, because this
specie does not have hematophagism habit on animals.
