This study was intended to determine the role played by peste des petits ruminants (PPR) in causing respiratory infections in camels and its association with other respiratory viruses. A total of 474 lung specimens showing pneumonia were collected from clinically healthy camels in slaughterhouses at five different areas in Sudan. Using immunocapture ELISA (IcELISA), 214 specimens (45.1 %) were found to be positive for PPR antigen. The highest prevalence was found in central Sudan (59.9 %) then northern Sudan (56.6 %) and eastern Sudan (26.6 %). Parainfluenza virus 3 (PIV 3), respiratory syncytial virus (RSV), bovine herpes virus-1 (BHV-1), bovine viral diarrhea (BVD), and adenovirus were detected in 4.4, 2.9, 2.0, 9.0, and 1.3 % of the specimens, respectively. PPR antigen was found in about 50 % of specimens that showed positive result for other viral antigens. Twenty-five of 28 BVD, 15 of 16 PIV3, 8 of 12 RSV, 4 of 4 adenovirus, and 4 of 5 BHV-1 were found in association with other respiratory antigens. Results revealed the existence of PPRV infection in dromedary camels in Sudan and present evidence for mixed virus infection, suggesting that respiratory infections in camels might be exacerbated by PPRV.
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.
