Contagious equine metritis.

Equine Veterinary Journal

|January 1, 1978

Summary

This summary is machine-generated.

An outbreak of contagious equine metritis (CEM) in Newmarket was caused by a Gram-negative coccobacillus. Venereal transmission was the primary spread, necessitating improved hygiene and screening for control.

Area of Science:

Veterinary Microbiology
Equine Infectious Diseases

Background:

Contagious Equine Metritis (CEM) is a significant venereal disease affecting horse populations.
An outbreak in Newmarket in 1977 highlighted the need for understanding its transmission and control.

Purpose of the Study:

To describe the 1977 outbreak of contagious equine metritis in Newmarket.
To identify the causative agent and understand its transmission routes.
To propose control measures for the disease.

Main Methods:

Isolation of the causative organism from affected mares.
Experimental reproduction of the disease in pony mares using pure cultures.
Observation of natural disease spread patterns.

Main Results:

Related Experiment Videos

A Gram-negative coccobacillus was identified as the causative agent.
The disease was successfully reproduced experimentally via cervical inoculation.
Natural transmission occurred through venereal contact and direct handling/examination of infected mares.

Conclusions:

Bacteriological screening of equine genital tracts and enhanced farm hygiene are recommended control strategies.
Further research is needed to fully establish effective disease control protocols.
