A Study on Morphology and Morphometry of Haemonchus contortus

Abstract

Haemonchus contortus has posed a great problem to researchers and has created confusion among them regarding its identification. In this study an attempt has been made to study the morphology and morphometry of Haemonchus contortus recovered from the ruminants and to relate it with some parameters like study area, host, intensity, methodology, age and sex of the host. It was observed that all these factors have some minor intraspecific effects on the morphology and morphometry of the parasites. These variations were of minor importance because they were found within the range of similarity and were not good enough to label it as a new species as was expected. Also some of the parameters with regard to morphology and morphometry of this parasite were described for the first time which were not described by the previous authors and these could be of great taxonomic importance for the identification of this parasite which is being confused many times and is being labeled a new species.
