Prevalence of Taylorella equigenitalis infection in stallions in Slovenia: bacteriology compared with PCR examination.

This research aimed to identify the prevalence of Taylorella equigenitalis infection in stallions in Slovenia, comparing traditional culture methods with Polymerase Chain Reaction (PCR) tests for more accurate diagnosis.

Objectives and Methodology

• The main objective of the research was to explore the prevalence of Taylorella equigenitalis, the causative organism of contagious equine metritis, in stallions in Slovenia.
• To accomplish this, the research team utilized both culture methods and Polymerase Chain Reaction (PCR) techniques. They hypothesized that PCR would be superior, particularly in cases where few causative agents were present or where genital swabs showed extensive contamination.
• A total of 980 genital swabs were taken from the urethra and fossa urethralis of 245 stallions for testing.

Findings

• Among the 245 stallions examined, 225 (91.8%) tested negative for T. equigenitalis with both testing methods.
• However, T. equigenitalis was isolated via the culture method from swabs taken from 17 stallions (6.9%) on the first or second sampling.
• Interestingly, swabs from 3 stallions (1.2%) tested positive with PCR, but failed to grow T. equigenitalis in culture.
• This illustrates a higher detection rate for T. equigenitalis using PCR than with traditional bacteriological examination methods.

Conclusions

• The study concluded that the PCR protocol used provided a specific, sensitive, and straightforward tool for rapid detection of T. equigenitalis.
• PCR was found to be a particularly valuable tool in cases where the bacterial and fungal contamination of swabs was significant. This is because such contamination usually leads to failure in isolating T. equigenitalis using traditional culture methods.
• In summary, this research suggests that PCR can provide more accurate results when testing for T. equigenitalis, helping to refine identification methods in stallions and enable better disease monitoring and control.
