Abstract

Virginia opossums (Didelphis virginiana) are the only native marsupials in the United States of America and Canada. Females have a reproductive tract consisting of a complex duplex (bifurcated) reproductive system, with 2 ovaries, 2 uteri and uterine tubes, and a vaginal complex composed of 2 lateral vaginae, vaginal sinuses, and a urogenital sinus. Few conditions of the reproductive tract have been described in these marsupials. A 2-y-old, female Virginia opossum was presented because of hematuria and was found dead shortly after admission. The autopsy revealed left lateral vaginal torsion and pyovagina. Streptococcus didelphis was isolated and identified from the lateral vaginal exudate, blood, and liver using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). Histologic examination confirmed suppurative and lymphoplasmacytic vaginitis, endometritis, cystitis, pyelonephritis and interstitial nephritis, portal hepatitis with fibrosis, myocarditis, and adrenalitis with intralesional gram-positive cocci. These results suggest ascending S. didelphis infection of the lateral vagina with subsequent torsion, bacterial translocation, bacteremia, and sepsis as the cause of death.

弗吉尼亚负鼠的脓毒症和脓毒症。
弗吉尼亚负鼠(Didelphis Virginia)是美国和加拿大唯一的本土有袋动物。女性的生殖道由一个复杂的双(分叉)生殖系统组成,包括两个卵巢、两个子宫和输卵管;阴道复合体由两个外侧阴道、阴道窦和一个泌尿生殖窦组成。在这些有袋动物中很少有生殖系统的情况被描述。一只两岁的弗吉尼亚雌性负鼠因血尿而入院,入院后不久就被发现死亡。尸检显示左侧阴道外侧扭转和阴道下垂。采用基质辅助激光解吸/电离飞行时间质谱法(MALDI-TOF MS)从阴道分泌物、血液和肝脏中分离鉴定双delphis链球菌。组织学检查证实化脓性和淋巴浆细胞性阴道炎、子宫内膜炎、膀胱炎、肾盂肾炎和间质性肾炎、门脉肝炎伴纤维化、心肌炎和肾上腺炎伴革兰氏阳性球菌。这些结果表明,上升的didelphis感染阴道外侧,随后扭转,细菌易位,菌血症和败血症是死亡的原因。
