RESUMO
Cats were infected experimentally with Salmonella typhimurium via the conjunctiva. Clinical signs consisted of lacrimation, conjunctivitis, blepharospasm, prominent nictitating membrane and scleral injection. These signs were accompanied by an absolute neutrophilia and conjunctival smears indicative of moderate to severe suppurative inflammation. Ocular signs disappeared by day 6 postinfection. Salmonella typhimurium was cultured intermittently from the inoculated conjunctivae and rectal swabs through day 7. At necropsy, mesenteric and cervical lymph nodes were enlarged. Histopathological findings included chronic conjunctivitis and lymphoid hyperplasia in cervical and mesenteric lymph nodes. This study confirms that S. typhimurium can cause a primary conjunctivitis and that the ocular route of infection can lead to fecal excretion of Salmonella, in the absence of other clinical manifestations.
