Listeriosis is a rare disease in cats with naturally occurring cases usually being identified in individual animals. Listerial mesenteric lymphadenitis has not been described previously in cats.
To describe the clinical and histological features of listerial mesenteric lymphadenitis in cats as well as treatment outcome.
Listerial mesenteric lymphadenitis was confirmed in 3 cats by histology, immunohistochemistry, and bacterial culture.
The affected cats were young to middle aged and were examined for various clinical signs. On both palpation and abdominal ultrasound examination, all cats had marked mesenteric lymphadenomegaly. Survival was prolonged in all 3 cases. Two of the 3 cats were fed a raw meat-based diet before they developed clinical illness.
Lymphadenitis caused by listeriosis has a protracted time course and should be a differential diagnosis for abdominal lymphadenopathy in young to middle-aged cats. Feeding of a raw meat-based diet may be a contributing factor for development of listeriosis in cats.
李斯特菌病在猫中较为罕见，通常在个别动物中发现自然发生的病例。猫李斯特氏肠系膜淋巴结炎以前尚未被描述过。
描述猫李斯特氏肠系膜淋巴结炎的临床和组织学特征以及治疗结果。
通过组织学、免疫组织化学和细菌培养证实 3 只猫患有李斯特氏肠系膜淋巴结炎。
受影响的猫年龄在幼龄到中年之间，并出现各种临床症状。在触诊和腹部超声检查中，所有猫都有明显的肠系膜淋巴结肿大。3 例猫的存活时间都延长了。在出现临床疾病之前，其中 2 只猫喂食生肉为主的饮食。
由李斯特菌引起的淋巴结炎具有较长的时间过程，应作为年轻到中年猫腹部淋巴结病的鉴别诊断。喂食生肉为主的饮食可能是猫李斯特菌病发展的一个促成因素。
