in calves: effects of dietary protein and multiple experimental infection on worm establishment and pathogenesis.
Raza et al.(2013) reported that age-wise prevalence of different GI nematodes in calf like Toxocara vitulorum was 25.64% while in adult animal it was 8.19%, Oesophagostomum radiatum was 2.56% in calf as compared in adult animal (3.27%), Haemonchus placei
was 2.56% in calf as compared to adult (0%) and Bunostomum phlebotomum was 2.56% in calf compared to adult (1.63%).
Com base nos resultados encontrados no presente estudo, pode-se concluir que as quatro populacoes de Haemonchus placei
e Cooperia punctata avaliadas sao resistentes a ivermectina, administrada via pour-on, na dose de 500mcg[kg.sup.-1].
Effects of time, day, season and stratum on Haemonchus contortus and Haemonchus placei
third stage larvae on irrigated pasture.
S p e c i e s r e c o r d e d w e r e Fasciola hepatica, Fasciola gigentica, Toxocara vitulorum, Paramphistomum cervi, Monezia expansa, Monezia bendeni, Oesophagostomum radiatum, Haemonchus placei
and Bunostomum phlebotomumn in cattle, an overall prevalence of helminths was 51% (255/500).
Dose confirmation study of a 1% moxidectin nonaqueous injectable formulation against [L.sub.4] larval and adult stages of Dictyocaulus viviparus, Haemonchus placei
and Trichostrongylus axei in cattle in Wisconsin.
(2013) revealed that prevalence of Haemonchus placei
was 0% in male cattle and 1.44% in female cattle.
Haemonchus contortus was the most prevalent species of helminth followed by Paramphistomum cervi, Oestertagia circumcincta, Fasciola hepatica, Chabertia ovina , Moniezia expansa, Oesophagostomum radiatum, Bunostomum phlebotomum, Haemonchus placei
, , M.
on free-living nematodes and infective larvae of Haemonchus placei
Identification of the helminths collected at necropsy revealed that Haemonchus and Cooperia corresponded to 35.1% and 58.3% of the mean parasitic load, respectively, and that Haemonchus placei
and Cooperia punctata were the most frequently observed species.
Por outro lado, BARGER (1999) afirma que o metodo perde eficacia na presenca de Haemonchus placei
- que parasita bovinos, ovinos e caprinos--e Trichostrongylus axei, de baixa especificidade parasitaria.
Haemonchosis caused by Haemonchus contortus and Haemonchus placei
is the most important disease of small ruminants in Pakistan Maqsoodet al.,(1996).
