A 1-yr-old female Canada lynx (Lynx canadensis) presented for sudden onset of rapidly progressive bilateral pelvic limb paralysis. The lynx was chemically immobilized to perform a physical examination but expired shortly thereafter. On postmortem radiographs, there were myriad small irregular, round-to-spherical gas densities within the skeletal muscle of the right thigh and epaxial musculature. At gross necropsy, the muscles of the right thigh, right lateral abdominal wall, and epaxial region were emphysematous and necrohemorrhagic, with subcutaneous and muscular crepitant swelling. Multiple skin puncture wounds, consistent with bites, were present over the affected tissues. Clostridium septicum was isolated in pure anaerobic culture from the musculature of the right hind limb. Histopathologic examination confirmed the diagnosis of acute, severe necrohemorrhagic and gangrenous myositis and cellulitis. Gram stains demonstrated large gram-positive bacilli with subterminal spores. This is the first known documented case of C. septicum myonecrosis in a nondomestic felid.
一只1岁的雌性加拿大猞猁（Lynx canadensis）因突然出现迅速进展的双侧后肢麻痹前来就诊。这只猞猁接受了化学保定以便进行体格检查，但随后不久死亡。死后X光片显示，右大腿骨骼肌和轴后肌肉组织内有无数小的不规则圆形至球形气体密度影。大体尸检时，右大腿、右侧腹壁和轴后区域的肌肉呈气肿性和坏死出血性，伴有皮下和肌肉捻发音肿胀。在受影响的组织上有多处与咬伤相符的皮肤穿刺伤口。从右后肢肌肉组织的纯厌氧培养物中分离出败血梭菌。组织病理学检查证实为急性、严重坏死出血性坏疽性肌炎和蜂窝织炎。革兰氏染色显示有带亚端芽孢的大革兰氏阳性杆菌。这是已知的第一例非家养猫科动物发生败血梭菌性肌坏死的记录病例。
