Diagnosis of Benzimidazole Resistance in Haemonchus contortus of Sheep by Allele Specific PCR
The study was conducted on 162 adult male Haemonchus contortus of sheep collected from Avikanagar, Jaipur and Bikaner regions to diagnose the benzimidazole (BZ) resistance in H. contortus. The BZ resistance is primarily linked with the mutation in β-tubulin isotype 1 gene which substitute phenylalanine (Phe) into tyrosine (Tyr) at the 200 codon of the gene. An allele specific polymerase chain r...
متن کاملDetection of Ethambutol-Resistant Associated Mutations in Mycobacterium tuberculosis Isolates from Iran Using Multiplex Allele-Specific PCR
Tuberculosis is a serious global public health problem and its high prevalence is stron gly associated with the enhancement of drug resistance. In this study we demonstrate a multiplex allele-specific polymerase chain reaction (MAS)-PCR assay to simultaneously detect mutations in the first and third bases of the embB gene codon 306 ATG in ethambutol (EMB) resistant isolates of Mycobacterium t...
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 کاملImmunological responses of sheep to Haemonchus contortus.
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...
