Abstract: Camel papillomatosis has been studied previously, but the clincopathological aspects of the disease have not been well described. Therefore, the present study aimed to investigate selected clinical, hematological and serobiochemical parameters as well as histopathological alterations in twenty naturally infected and twenty healthy camel calves. Inappetence, restlessness, followed by localized skin warts in the lips and lower jaw and intermittent scratching of the affected area were the main clinical signs of the disease. The obtained results indicated that, the diseased camel calves showed a significant decrease (p<0.001) in Total Erythrocyte Count (TEC), Hemoglobin concentration (Hb), Packed Cell Volume (PCV), Total Leucocyte Count, (TLC), neutrophil%, lymphocyte%, total proteins, sodium and potassium. The biochemical findings indicated that affected camel calves had significantly (p<0.001) higher values for Alanine aminotransferase, ALT (15.9±0.50 IU L-1), Aspartate aminotransferase AST (175.1±3.1 IU L-1), Gamma glutamyl transferase, GGT (33.1±1.40 IU L-1) and Alkaline phosphatase, ALP (106.2±2.4 IU L-1) compare to healthy camel calves, respectively (12.4±3.1, 137.0±3, 22.4±2.3 and 42.2±1.90 IU L-1). However, affected camel calves had significantly (p<0.001) lower values for total protein (5.4±0.07 g dL-1), sodium (101.5±11.1 mEq L-1) and potassium (5.5±0.82 mEq L-1), when compared to healthy camel calves, respectively (7.11±1.77 g dL-1; 130±12.1, 7.1±0.85 mEq L-1). The biopsy samples revealed multiple papillary proliferations covered with keratinized zone of epithelium. Hyperkeratosis, acanthosis and dermal fibrosis were also observed. This study confirms that papillomatosis occurs in camels in Saudi Arabia and is associated with hematological, serobiochemical and clinicopathological changes.
