Abstract

Abstract: Klebsiella spp. are gram-negative facultative anaerobic heavily encapsulated bacteria associated with opportunistic and primary infections in a wide range of species. We assessed a series of cases (n=8) of necrosuppurative peritonitis, lymphadenitis, and/or pyelonephritis in wild juvenile raccoons (Procyon lotor) that died under rehabilitator care in New York, New Jersey, and Wisconsin, US, between July 2020 and December 2023, plus a retrospective case of a juvenile raccoon necropsied from New York in August 2011. Gross necropsy (n=9) and histopathology (n=9) were performed to characterize the lesions, whereas bacterial culture (n=8) was used to identify and characterize the bacteria and associated phenotype. We observed gram-negative short rods and coccobacilli (7/9; 78%), fibrinosuppurative peritonitis of variable severity (7/9; 78%) correlated to gross pyoabdomen (5/9; 56%) or abscessation (2/9; 22%), lymphadenomegaly and associated necrosuppurative lymphadenitis (5/9; 56%), and urinary tract disease (3/9; 33%). Aerobic culture of affected tissues isolated Klebsiella pneumoniae (n=4), K. pneumoniae subsp. ozaenae (n=2), Klebsiella variicola (n=1), and Klebsiella sp. (n=1). Our study strongly suggests an association of bacteria within the K. pneumoniae complex with peritonitis, lymphadenitis, and pyelonephritis in raccoons. Disease might be associated with underlying nosocomial infection given that all animals were under rehabilitator care at the time of death.

美国纽约、新泽西州和威斯康星州由康复者照料的幼年浣熊(Procyon lotor)的复合肺炎克雷伯氏菌相关腹膜炎、淋巴腺炎和肾盂肾炎。
摘要:克雷伯氏菌属是革兰氏阴性兼性厌氧重型包裹菌,与多种物种的机会性感染和原发性感染有关。我们评估了 2020 年 7 月至 2023 年 12 月期间在美国纽约、新泽西州和威斯康星州死于康复者照料的野生幼貉(Procyon lotor)的一系列坏死性腹膜炎、淋巴腺炎和/或肾盂肾炎病例(n=8),以及 2011 年 8 月在纽约尸检的一例幼貉的回顾性病例。尸体解剖(9 只)和组织病理学(9 只)是为了确定病变的特征,而细菌培养(8 只)则是为了确定细菌和相关表型的特征。我们观察到革兰氏阴性短杆菌和球菌(7/9;78%)、严重程度不一的纤维素性腹膜炎(7/9;78%)、与严重腹腔积液(5/9;56%)或脓肿(2/9;22%)相关的淋巴结肿大和相关的坏死化脓性淋巴结炎(5/9;56%)以及尿路疾病(3/9;33%)。受影响组织的需氧培养分离出肺炎克雷伯菌(4 个)、肺炎克雷伯菌亚种(2 个)、变异克雷伯菌(1 个)和克雷伯菌属(1 个)。我们的研究强烈表明,肺炎克雷伯菌复合体中的细菌与浣熊腹膜炎、淋巴结炎和肾盂肾炎有关。鉴于所有动物死亡时都在康复人员的照料下,疾病可能与潜在的院内感染有关。

期刊介绍: The JWD publishes reports of wildlife disease investigations, research papers, brief research notes, case and epizootic reports, review articles, and book reviews. The JWD publishes the results of original research and observations dealing with all aspects of infectious, parasitic, toxic, nutritional, physiologic, developmental and neoplastic diseases, environmental contamination, and other factors impinging on the health and survival of free-living or occasionally captive populations of wild animals, including fish, amphibians, reptiles, birds, and mammals. Papers on zoonoses involving wildlife and on chemical immobilization of wild animals are also published. Manuscripts dealing with surveys and case reports may be published in the Journal provided that they contain significant new information or have significance for better understanding health and disease in wild populations. Authors are encouraged to address the wildlife management implications of their studies, where appropriate.
