Abstract

BACKGROUND

Three horse mares inadvertently inseminated with semen from a Tayorella asinigenitalis-positive Jack donkey developed severe, purulent endometritis whereas two Jenny donkeys mated naturally to the same Jack donkey did not develop clinical signs of infection.

OBJECTIVES

To isolate and identify the causative agent.

STUDY DESIGN

Case report.

METHODS

Endometrial swabs from the infected mares were cultured on selective and non-selective media under aerobic and microaerophilic conditions. Isolates were subjected to Gram staining, oxidase and catalase tests, the Monotayl Latex Agglutination test and PCR to test for both T. equigenitalis and T. asinigenitalis. In vitro antimicrobial susceptibility testing was performed and the bacterial isolate was genotyped using MLST.

RESULTS

A new sequence type of T. asinigenitalis was confirmed.

MAIN LIMITATIONS

A limited numbers of mares and donkeys are described.

CONCLUSIONS

This strain of T. asinigenitalis causes a severe venereal infection in mares but not in Jenny donkeys.

摘要

背景

三头母马意外地被感染 Tayorella asinigenitalis 的公驴的精液受精，导致严重的化脓性子宫内膜炎，而两头自然交配的母驴则没有表现出感染的临床症状。

目的

分离并鉴定病原体。

研究设计

病例报告。

方法

从感染的母马的子宫内膜拭子在有氧和微需氧条件下的选择性和非选择性培养基上进行培养。将分离物进行革兰氏染色、氧化酶和过氧化氢酶试验、Monotayl Latex Agglutination 试验和 PCR 检测，以检测 T. equigenitalis 和 T. asinigenitalis。进行体外抗菌药敏试验，并使用 MLST 对细菌分离株进行基因分型。
