Cats exposed to aerosols of feline Chlamydia psittaci developed a disease characterized principally by conjunctivitis. Signs of conjunctivitis appeared between postexposure days (PED) 5 and 10, were often unilateral initially, and persisted for 22 to 45 days. Fever followed the onset of conjunctivitis (PED 11 to 15) and persisted for 3 to 8 days. Signs of mild rhinitis (occasional sneezing and mild serous nasal discharge) occurred in some cats between PED 8 and 37. Neither signs of lower respiratory tract disease nor significant pulmonary lesions were produced by the feline pneumonitis agent. Small foci of pneumonia were detected microscopically in 3 of 6 cats examined between PED 7 and 14. Chlamydiae were identified between PED 7 and 14 in the cytoplasm of epithelial cells in stained conjunctival smears. Conjunctivitis persisted for at least 18 days after chlamydiae no longer were detectable in conjunctival smears. Low levels of chlamydial infectivity, however, still were present in conjunctiva and lung on PED 45.
暴露于猫衣原体气溶胶的猫会患上一种主要以结膜炎为特征的疾病。结膜炎症状在暴露后天数（PED）5至10天之间出现，最初通常为单侧，持续22至45天。发热在结膜炎发作后出现（PED 11至15天），持续3至8天。一些猫在PED 8至37天之间出现轻度鼻炎症状（偶尔打喷嚏和轻度浆液性鼻分泌物）。猫肺炎病原体未引起下呼吸道疾病症状或明显的肺部病变。在PED 7至14天检查的6只猫中，有3只在显微镜下检测到小的肺炎病灶。在PED 7至14天之间，在染色的结膜涂片上皮细胞的细胞质中鉴定出衣原体。在结膜涂片中不再检测到衣原体后，结膜炎仍持续至少18天。然而，在PED 45天时，结膜和肺中仍存在低水平的衣原体感染性。
