Abstract Rotavirus is one of the major causes of diarrhea in different animal species and has a bad economic impact due to the losses in neonates and productivity. To investigate the occurrence of this infection in bovine calves, three localities in Khartoum State, Sudan, were selected. A total of 200 fecal samples were collected from diarrheic calves; 100 from Khartoum and 50 from each of Khartoum Bahari and Omdurman provinces. Collected samples were screened for a group A rotavirus antigen using enzyme-linked immunosorbent assay (ELISA). Positive results were seen in 40.00% of samples; the highest prevalence of 42.00% was found in samples from Khartoum province. Five ELISA-positive samples were examined under electron microscope, and characteristic wheel-like appearance of rotavirus was visualized. Polyacrylamide gel electrophoresis was also applied on 15 of the positive samples; eight samples showed different polyacrylamide gel electrophoretic group A rotavirus long profile with different patterns. The results showed that the occurrence of rotavirus infection in cattle in Khartoum State is increasing.

Abstract Respiratory infections are considered within the major constraints of animal production; viruses are the major causing pathogens. This study aimed to elucidate the prevalence of parainfluenza virus-3 (PIV-3), bovine viral diarrhea virus, and respiratory syncytial virus (RSV) in sheep and goats and the existence of co-infections. A total of 270 sheep and 220 goat pneumonic lung tissues were collected from slaughterhouses in four different areas. Enzyme-linked immunosorbent assay was used to detect the antigen of the three viruses, fluorescent antibody technique and polymerase chain reaction confirmed enzyme-linked immuno-sorbent assay positive results. Prevalence detected for PIV-3 was 11.10% in sheep and 9.50% in goats, pestivirus was 10.40% in sheep and 7.70% in goats, and RSV was 17.80% in sheep and 5.00% in goats. Detected co-infections were 5.60% for PIV-3 and pestivirus in sheep and 4.00% in goats and pestivirus and RSV was observed only in goats (1.40%). Co-infection of the three viruses was detected in only one goat sample (1.00%). The existence of the three viruses in sheep and goats was confirmed. To our knowledge, this is the first report of the co-infections of PIV-3, pestivirus, and RSV in sheep and goats in the studied areas.
