Successful Eradication of Taylorella asinigenitalis, Pseudomonas aeruginosa, and Klebsiella pneumoniae Venereal Bacterial Pathogens Using Domestic Steam Disinfection: Implications for AI Practice

Millar, Beverley C. | Moore, J. E. (John E.)
Steam disinfection has become established as a trusted method of microbial decontamination; however, there have been no reports on the use of this technology to disinfect equipment used in collection of semen in artificial insemination practice. Hence, it was the aim of this study to examine the survival of Taylorella asinigenitalis, Pseudomonas aeruginosa, and Klebsiella pneumoniae venereal bacterial pathogens using domestic steam disinfection. Sixteen bacterial pathogens from three genera Taylorella, Pseudomonas, and Klebsiella each at an inoculum density of approximately 1.5 × 10⁷ colony-forming units were subjected to a steam disinfection cycle. No bacteria were recovered after disinfection, including following recovery and nonselective cultural enrichment techniques. In the absence of full sterilization, domestic steam disinfection of equipment offers a cheap, simple, and widely available technology for the elimination of these pathogens, thereby enhancing infection control in equine breeding.
