Infections with Haemonchus contortus are a major constraint on ruminant health world-wide. Young lambs are very sensitive to Haemonchus infection. Older lambs and sheep acquire immunity after a continuous or seasonal exposure to the parasite. The mechanisms underlying immunity are still not completely understood. Antibodies, in particular local IgA and IgE, certainly play a role. The role of Ig...

متن کاملImmunodiagnosis of Haemonchus contortus infection in sheep by indirect enzyme linked immunosorbent assay (ELISA)
Indirect plate enzyme-linked immunosorbent assay was standardized and evaluated for its effectivenessin immunodiagnosis of haemonchosis in experimental and clinical cases in sheep by using somatic wholeadult antigen of H. contortus. Plate ELISA was standardized using 5 μg/well antigen concentration with1:100 and 1:1000 of sera and conjugate dilution. Indirect plate ELISA was able to demonstrate...
متن کاملStudy of β-tubulin gene polymorphisms in Haemonchus contortus isolated from sheep populations in Khouzestan, southwestern Iran
In this report, β-tubulin gene polymorphism was investigated in Haemonchus contortus populations isolated from sheep flocks in different regions of Khouzestan province, southwestern Iran. The samples were chosen on the basis of regional variation in benzimidazole treatment background of sheep flocks. Our objective was to study the relationship between treatment background andβ -tubulin gene po...
متن کاملImmunization of Arabian sheep with whole gut homogenate of Haemonchus contortus
Ten female lambs of 7-month-old were divided into two equal groups and raised under a helminth-free conditions. Animals in group 1 were immunized two times by whole gut homogenate (WGH) of Haemonchus contortus emulsified in Freund’s adjuvant. In group 2 (control), animals were injected by phosphate buffered saline emulsified in the same adjuvant. Animals were challenged by 10000 third-stage lar...
