A 14-week-old kitten had a history of vomiting, diarrhoea and pyrexia, all of which resolved without treatment. Three weeks later the kitten developed a violent non-productive dry cough. Thoracic radiographs revealed pneumothorax and nodular alveolar disease. Aelurostrongylus abstrusus larvae and intracellular Gram-negative bacilli were seen in bronchial wash fluid and pleural exudate, and Salmonella Typhimurium was cultured from both fluids but not from faeces. Therapy included unilateral closed-tube thoracostomy, enrofloxacin and fenbendazole. Historical signs were compatible with gastrointestinal salmonellosis and secondary broncho-pneumonia. Seeding of the lungs with salmonellae may have occurred as a result of migration of A abstrusus from a gastro-intestinal tract residually infected or colonised by S Typhimurium. Alternatively, the development of lungworm infection in the cat may have activated quiescent S Typhimurium pulmonary granulomata from bacteraemia secondary to gastro-intestinal salmonellosis. Two years after diagnosis the cat was reportedly in good health.
一只14周大的小猫有呕吐、腹泻和发热病史，未经治疗这些症状均自行缓解。三周后，小猫出现剧烈的无痰干咳。胸部X光片显示气胸和结节状肺泡疾病。在支气管冲洗液和胸腔积液中发现了隐匿猫圆线虫幼虫和细胞内革兰氏阴性杆菌，两种液体中均培养出鼠伤寒沙门氏菌，但粪便中未培养出。治疗包括单侧闭式胸腔引流、恩诺沙星和芬苯达唑。既往症状与胃肠道沙门氏菌病和继发性支气管肺炎相符。肺部感染沙门氏菌可能是由于隐匿猫圆线虫从残留感染或被鼠伤寒沙门氏菌定植的胃肠道迁移所致。或者，猫感染肺线虫可能激活了由胃肠道沙门氏菌病继发菌血症引起的静止性鼠伤寒沙门氏菌肺肉芽肿。据报道，诊断两年后这只猫健康状况良好。
