Relação sexual do parasitismo por Haemonchus contortus em Caprinos (Capra hircus)

Abstract

The hemoncose is an important parasitic disease to livestock, being the species sheep and goats the most affected. This disorder is caused by the nematode Haemonchus sp. abomasal parasite, measuring 1 to 2.5 cm. This is the most pathogenic helminthes, causing reduction of weight gain, severe anemia, edema of the gastric mucosa promoting decreasing the absorption of nutrients, external swelling called "edema of dewlap", and it’s characteristic signs of hemoncose, besides causing death in severe parasitosis. The aim of this study was describe the abomasal parasite fauna and sexual parasitism with Haemonchus contortus. Abomasal samples were collected after slaughter of goats, being recovered a total of 12460 helminths. The slaughtered animals were observed before and after slaughter. Before the slaughter were observed hair bristly and opaque, beyond severe anemia. After killing was observed abomasal parasitism by H.contortus and T.axei, where the parasitic load of H. contortus was accounted for more than 98% of parasitism, being equivalent the relation between male and female, in addition of the parasitism was observed mucosal lesions caused by fixation of nematode in abomasum, and pale carcass.

Comparing McMaster and Mini-FLOTAC for endoparasites diagnostic in goats

“…Cardoso et al (2017) and Dias et al (2017) highlighted that the coccidia gender Eimeria are those who most affect the goats production in the world. Regarding the helminths found in the present study, it is noted that other previous works indicated the presence of Oesophagostumum sp., Haemoncus sp., and Strongyloides, as the parasites that most affect sheep and goats in the western Rio Grande do Norte, Brazil (AHID et al, 2008;FONSECA et al, 2011). Regarding the Kappa concordance values, among the studied techniques, it was observed that there was a moderated to strong concordance, therefore considered as similar (Table 3).…”

Haemonchus contortus e Medidas Estratégicas de Controle para Ovinos

“…Segundo Vieira (2007), os efeitos do parasitismo no rebanho se manifestam de várias formas, conforme as espécies presentes, a intensidade da infecção, a categoria e o estado fisiológico e nutricional do hospedeiro. O diagnóstico, de forma geral, é baseado em sinais clínicos, que na forma aguda apresentam perda de peso, diarreia, pelos arrepiados e sem brilho, anemia, desidratação e edema submandibular (FONSECA et al, 2011). A coprologia ajuda identificar a presença de ovos e larvas nas fezes (ROBERTO, 2018) e os achados na necropsia para verificar as lesões, assim como contagem de parasitos presentes no abomaso e outras espécies que possam acometer o hospedeiro (SCZESNY-MORAES et al, 2010).…”

“…Dessa forma, há aumento significativo na frequência de helmintoses gastrointestinais no rebanho nessas áreas para pastejo. Pastagens irrigadas podem influenciar na disponibilidade de L3, sendo encontradas larvas maciçamente no verão e em temperatura de 24°C (FONSECA et al 2011). Temperatura e umidade são fatores determinantes na sobrevivência das larvas em vida livre.…”
