Aim:The study was conducted in Basrah, Iraq, to diagnose congenital arthrogryposis-hydranencephaly syndrome caused by Akabane virus (AKAV) in calves.Materials and Methods:Affected animals (42 calves) are about 2-27 days old from both sexes show signs of arthrogryposis and hydranencephaly. Eight clinically healthy newborn calves were considered as controls. Diagnosis of AKAV was confirmed using a competition enzyme-linked immunosorbent assay test.Results:Results show that all affected calves were found seropositive. Furthermore, a significant increase in total leukocyte count in diseased calves due to a significant increase in the absolute lymphocyte number indicated in affected calves than in controls. Moreover, a significant increase in sedimentation rate of erythrocytes was also encountered in diseased calves than in controls. In addition, a significant increase in haptoglobin level and fibrinogen was also detected.Conclusion:Diagnosis of AKAV infection of Basrah Governorate, Iraq, will provide useful epidemiological information for cattle and other domesticated animals. Therefore, abortion could be prevented and controlled.
Vitamin C is an important water-soluble antioxidant, which plays necessary roles in an animal's body, especially in neonatal dairy calves. Neonatal dairy calves receive vitamin C from their dam, and in unique situations, it can cause problems within the calf, specifically skin lesions, or dermatosis. This study aims to determine the effects of vit. C deficiency on the skin and coat integrity of the neonate calves. In this study, 10 neonatal dairy calves were used. Five calves were served as the control group, and the other 5 calves were tested for clinically affected with ascorbic acid deficiency. The clinical findings showed that severe scaling, alopecia in different areas of the body, pinna erythematous, purpuric, and pruritus. Samples of plasma were collected to estimate the value of vitamin C and some blood film parameters. The findings also revealed that significant decreases in the level of vitamin C, counting of erythrocytes, concentration of haemoglobin, and packed cell volume. Furthermore, there were significant changes in the neutrophils. Histopathological results revealed hyperkeratosis and congestion in the skin layers. After affected calves were treated with vitamin C, there was improvement and gradual disappearing of the skin gross changes. This study found a close relationship between the vitamin C deficiency in dairy calves and dermatosis (skin integrity).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
