Heavily encapsulated strain of Klebsiella pneumoniae (K. pneumoniae) capsular type 1 inoculated into the uterus of a mare and filly caused severe and moderate metritis, respectively, while the less heavily encapsulated strain caused only very slight metritis in only 1 of 2 mares and nothing in a filly. Heavily encapsulated strain was recovered from uterine swabs of the mare and filly until the 25th and 21st post-inculation days (PIDs), respectively, and was recovered at autospy on the 23rd and 48th PIDs from the uterus and vagina, respectively. Less heavily encapsulated strain was recovered from uterine swabs of only 1 mare until the 8th PID only, but not from the remaining mare and filly, and the recovery of the organisms from the uterus and vagina at autopsy on the 20th and 27th PIDs was negative. Non-capsulated strain did not cause any metritis in a mare and a filly and the organisms were not recovered from uterine swabs from the 2nd PID nor at autospy on the 20th and 21st PIDs from the uterus and vagina.
