Abstract
To describe the cytological analysis of conjunctiva from normal camels and camels with bacterial conjunctivitis.
This study was conducted on 7 normal camels and 15 camels affected with conjunctivitis. The affected camels had a history of conjunctivitis with signs including chemosis, blepharospasm, frequent blinking, and mild-to-moderate serous, mucoid, or purulent ocular discharge.
Bacterial swabs were collected from the inferior conjunctival sac of the affected eye without topical anesthetics. Conjunctival smears were obtained from the conjunctival surface for cytological analysis.
The cellular analysis of ocular smears revealed a higher percentage of basal cells, neutrophils, eosinophils, and macrophages in camels with conjunctivitis compared with normal camels. In contrast to this, smears from normal camels showed an increased percentage of superficial epithelial cells compared with affected camels. The microbiological assessment of conjunctival swabs collected from affected animals identified a bacterial growth of Staphylococcus aureus., Bacillus sp., Streptococcus sp., Enterococcus faecium., Staphylococcus sp., Corynebacterium sp., Coryne pseudotuberculosis., Saprophytica, Enterobacter cloacae, Escherichia coli, Proteus mirabilis, Proteus vulagaris, and Pseudomonas aeruginosa.
It was observed that bacterial conjunctivitis in camels was associated with increased percentages of basal epithelial cells, neutrophils, eosinophils, and macrophages compared with normal camels, while normal camels showed an increased percentage of superficial epithelial cells compared with affected camels.
