Epidemiological, Morphological, and Morphometric Study on Haemonchus spp. Recovered From Goats in Egypt

Area of Science:

• Veterinary Parasitology
• Epidemiology
• Zoology

Background:

• Haemonchus species are significant abomasal parasites causing mortality and economic losses in goats.
• Limited information exists on hemonchosis prevalence and risk factors in Egyptian goats.
• Understanding infection dynamics is crucial for effective parasite control strategies.

Purpose of the Study:

• To investigate the prevalence of Haemonchus species in goats in Assiut Governorate, Egypt.
• To identify major risk factors associated with Haemonchus infection in goats.
• To characterize the Haemonchus species present in the study population.

Main Methods:

• Postmortem examination of 240 goat abomasum samples from Assiut Governorate, Egypt.
• Analysis of risk factors including age, sex, and sampling season.
• Identification and morphological characterization of Haemonchus species using light microscopy and Scanning Electron Microscopy (SEM).

Main Results:

• A prevalence of 16.66% for Haemonchus species infection was observed.
• Significant risk factors included older age (≥1 year), male sex, and summer season.
• Three Haemonchus species (H. contortus, H. placei, H. longistipes) were identified for the first time in Egyptian goats.

Conclusions:

• Age, sex, and season are critical epidemiological factors for hemonchosis in Egyptian goats.
• The identification of specific Haemonchus species provides essential data for targeted control measures.
• Further research into circulating parasite species is recommended for disease management in Egypt.
