RESUMO

INTRODUCTION: In recent years Peste des petits ruminants (PPR) disease caused several epidemics in a wide range of susceptible hosts. The ability of the peste des petits ruminants virus (PPRV) to cross the species barrier necessitates further research, particularly on disease circulation and cross-species transmission between typical and atypical hosts to guide and facilitate the eradication program anticipated by the Food and Agriculture Organization (FAO) and the World Organization for Animal Health (OIE) in 2030. The aim of this study is to explore the role of dromedary camels as transmitters for PPR. METHODOLOGY: Four experiments were carried out on clinically healthy seronegative camels, sheep and goats. In experiment I, the animals were inoculated with a PPR- positive suspension of camel pneumonic lung homogenate. In the other three experiments either sheep and goats were inoculated and after three days were housed with camels or vice versa. RESULTS: Marked clinical signs suggestive of PPR were seen in sheep and goats while camels showed mild infection. Severe clinical signs of PPR were seen in sheep and goats when kept with inoculated camels. Postmortem examination revealed PPR lesions in all inoculated animals including camels. CONCLUSIONS: This study showed that dromedary camels infected with PPRV can transmit the disease to sheep and goats, even when they developed mild clinical signs.

RESUMO

Congenital radioulnar synostosis is a rare developmental skeletal malformation of the upper limb, characterized by the fusion of the proximal ends of the radius and ulna from birth. The failure of prenatal longitudinal segmentation of the adjacent radius and ulna results in a fibrous bony bridge between the radius and ulna. We present a 23-year-old female who presented with pain and restricted mobility of the left elbow joint for 7 years. A plain X-ray was performed for the patient, revealing a diagnosis of congenital radio-ulnar synostosis. Careful evaluation of the anatomical relations and spatial orientation of bony structures is required for the diagnosis and treatment of such cases.

RESUMO

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.
