Camel pox (CMLP), a contagious viral disease of camels, causes considerable economic loss in terms of milk, meat, wool, and leather production besides reduction of draught power. The effect of spontaneous CMLP infection on hemogram, oxidative/nitrosative imbalance, and trace mineral homeostasis has not been studied earlier in dromedary camels. In the current study, hemogram, serum biochemistry, oxidant/antioxidant imbalance, and zinc (Zn)-copper (Cu) homeostasis were evaluated in healthy and pox-infected camels. The CMLP was confirmed from pooled samples of vesicular fluid, oral mucosa, and skin samples by polymerase chain reaction (PCR) targeting the C18L gene of CMLP virus. Hemogram was performed manually in whole blood. The serum was analyzed for biochemistry. The oxidative/nitrosative imbalance was measured by determining the concentrations of malondialdehyde (MDA), nitrite and nitrate (NOx), and glutathione S-transferase (GST) activity in serum. Simultaneously, copper (Cu) and zinc (Zn) concentrations were measured in serum. A pronounced leucopenia (p = 0.019), lymphopenia (p = 0.005), and hypoproteinemia (p = 0.014) were noted in CMLP-infected camels compared to healthy animals. The significant elevation of the MDA (p = 0.005) and NOx (p = 0.044) concentrations in serum of CMLP-infected indicated marked oxidative stress during the disease. The zinc concentration (p = 0.014) in CMLP-infected camels was significantly lower than healthy camels. The study supports that oxidative/nitrosative imbalance and Cu-Zn homeostasis are compromised and related to the pathophysiology of CMLP infection. The finding will be helpful to veterinary clinicians to adopt effective therapeutic strategies using antioxidants and trace minerals during CMLP outbreak. The timely vaccination and bio-security will be the mainstay for prevention of the diseases. |
