- Bacteria are commonly isolated from the penis; harmless commensals must be differentiated from agents of venereal disease.
- Cause : significant organisms are Klebsiella pneumoniae , Pseudomonas aeruginosa and Taylorella equigenitalis .
- Signs : subclinical infection or colonization on external genitalia of stallions. Most commonly, stallion is lesionless carrier. Rarely, a stallion may have internal accessory sex gland infection with Pseudomonas resulting in purulent material being present in ejaculates.
- Diagnosis : microbiologic culture of swabs from appropriate sites .
- Treatment : removal of smegma; administration of antimicrobials if necessary.
- Prognosis : good with appropriate therapy.
- Commensal organisms.
- Agents associated with sporadic cases of venereal disease:
- Agents associated with outbreaks of venereal disease:
- Agents of uncertain significance:
- Enterobacter .
- Clostridium species [Clostridia spp] .
- Good with appropriate therapy in CEM.
- Good to fair in Pseudomonas and Klebsiella infections.
- Chronic carriers can occur.
Expected response to treatment
- Negative bacteriologic cultures for pathogens.
Reasons for treatment failure
- Overzealous antiseptic washing - removing normal flora.
- Failure to eliminate infection by inappropriate or inadequate therapy.
- Failure to implement Codes of Practice rigorously.
