First description of the horse stomach worm, Habronema muscae (Spirurida: Habronematidae) by scanning electron microscopy.

Abstract: Habronema muscae (Spirurida: Habronematidae) occurs in the stomach of equids, is transmitted by adult muscid dipterans and causes gastric habronemiasis. Scanning electron microscopy (SEM) was used to study the morphological aspects of adult worms of this nematode in detail. The worms possess two trilobed lateral lips. The buccal cavity was cylindrical, with thick walls and without teeth. Around the mouth, four submedian cephalic papillae and two amphids were seen. A pair of lateral cervical papillae was present. There was a single lateral ala and in the female the vulva was situated in the middle of the body. In the male, there were wide caudal alae, and the spicules were unequal and dissimilar. At the posterior end of the male, four pairs of stalked precloacal papillae, unpaired post-cloacal papillae and a cluster of small papillae were present. In one case, the anterior end showed abnormal features.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article focuses on the detailed morphological study of the horse stomach worm, Habronema muscae, using scanning electron microscopy.

Objective of the Research

  • The primary focus of this research was observing and analyzing the morphological characteristics of Habronema muscae, a kind of nematode that infests the stomach of equids, causing gastric habronemiasis.

Methodology

  • For a detailed analysis of the worm’s morphology, Scanning Electron Microscopy (SEM) was employed. SEM is widely used in biological research to examine the structure and composition of biological samples.

Research Findings

  • The researchers identified two trilobed lateral lips on the worms, which were previously unnoticed.
  • Observation of the buccal cavity revealed it to be cylindrical and thick-walled without any teeth.
  • The researchers identified four submedian cephalic papillae and two amphids around the mouth of the nematode.
  • The existence of a pair of lateral cervical papillae was confirmed.
  • In female Habronema muscae, the vulva was observed to be situated in the middle of the body.
  • In the case of males, wide caudal alae were observed, and the spicules were found to be unequal and dissimilar.
  • The posterior end of the male worms showed four pairs of stalked precloacal papillae, unpaired post-cloacal papillae, and a group of small papillae.
  • An instance of abnormal features at the worm’s anterior end was also noted in the study.

Significance of the study

  • This research provides valuable morphological insights into Habronema muscae, which contribute significantly to the understanding of the anatomy of this nematode species.
  • These findings will help in the development of improved diagnostic strategies for identifying habronemiasis, a digestive system disorder in horses caused by this stomach worm.
  • The information can also be utilized for creating better preventive measures and treatments for habronemiasis in horses.
