Occurrence of Oesophagostomum species in slaughtered sheep in area of Hyderabad, Telangana State

Abstract

A study was conducted in Chengicherla slaughter house of Hyderabad to find the occurrence of Oesophagostomum worms, 594 oesophagostomum positive intestines were examined. Among these, three species of oesophagostomum worms were recovered viz., , and were identified by light microscopy as per the keys provided by Soulsby (Helminths, arthropods and protozoa of domesticated animals. Bailliere Tindall, London, 1982) and Singh (Veterinary helminthology. ICAR, Delhi, 2003).

Comparison of the first time detected Oesophagostomum asperum with Oesophagostomum columbianum in sheep and goats in Bangladesh based on the trinity: Morphology, morphometry and genetic diversity

“…Spicules were equal in length just like Soulsby (1982) detected. In female, Gaddam et al, (2017) and Singh (2003) reported that the tail tapered abruptly with shorter distance between vulva and tail tip which is coherent with the present study findings. In addition, the length and position of vagina endorse the descriptions of Singh (2003) .…”

“…Yadav and Tandon (1992) illustrated similar features of this study regarding mouth collar and cervical groove. In male O. asperum , the statement of this study explaining developed bursa along with lateral and dorsal rays expressed similarity with Gaddam et al, (2017) and Singh (2003) . Spicules were equal in length just like Soulsby (1982) detected.…”

“…This study announced with certainty the morphological elements of O. asperum describing dioecious nature and sexual dimorphism are in agreement with Nath et al, (2021) . Unlike O. columbianum , O. asperum depicted inflated cervical vesicle which mimics the explanation of Gaddam et al, (2017) and Singh (2003) . However, there was absence of lateral alae in this study which is in coincidence with the statement of Soulsby (1982) .…”

“…After isolation of adult parasites, they were washed multiple times with phosphate buffered saline (PBS) and subjected to morphological identification using lactophenol blue and identified according to keys and description given previously ( Bowman, 2014 , Gaddam et al, 2017 , Singh, 2003 , Soulsby, 1982 ,).…”

Concurrent Infection of Oesophagostomum species in a Slaughtered Goat: A Case Report

“…In a 2017 study, Gaddam et al found 594 Oesophagostomum positive intestines in the Chengicherla slaughterhouse in Hyderabad. The study was done to determine the occurrence of Oesophagostomum worms using a light microscope and three species of Oesophagostomum worms-Oesophagostomum columbianum, O. venulosum, and O. asperumwere found [13].…”
