Epidemic of blindness in kangaroos - evidence of a viral aetiology

OBJECTIVE: To determine the cause of an epidemic of blindness in kangaroos. DESIGN AND PROCEDURES: Laboratory examinations were made of eyes and brains of a large number of kangaroos using serological, virological, histopathological, electron microscopical, immunohistochemical methods, and PCR with cDNA sequencing. In addition, potential insect viral vectors identified during the disease outbreak were examined for specific viral genomic sequences. SAMPLE POPULATION: For histopathological analysis, 55 apparently blind and 18 apparently normal wild kangaroos and wallabies were obtained from New South Wales, Victoria, South Australia, and Western Australia. A total of 437 wild kangaroos and wallabies (including 23 animals with apparent blindness) were examined serologically. RESULTS: Orbiviruses of the Wallal and Warrego serogroups were isolated from kangaroos affected with blindness in a major epidemic in south-eastern Australia in 1994 and 1995 and extending to Western Australia in 1995/96. Histopathological examinations showed severe degeneration and inflammation in the eyes, and mild inflammation in the brains. In affected retinas, Wallal virus antigen was detected by immunohistochemical analysis and orbiviruses were seen in electron microscopy. There was serological variation in the newly isolated Wallal virus from archival Wallal virus that had been isolated in northern Australia. There were also variations of up to 20% in genotype sequence from the reference archival virus. Polymerase chain reactions showed that Wallal virus was present during the epidemic in three species of midges, Culicoides austropalpalis, C dycei and C marksi. Wallal virus nucleic acid was also detected by PCR in a paraffin-embedded retina taken from a blind kangaroo in 1975. CONCLUSION: Wallal virus and perhaps also Warrego virus are the cause of the outbreak of blindness in kangaroos. Other viruses may also be involved, but the evidence in this paper indicates a variant of Wallal virus, an orbivirus transmitted by midges, has the strongest aetiological association, and immunohistochemical analysis implicates it as the most damaging factor in the affected eyes.  相似文献   

Effect of body size, photophase, feeding and emersion on the oxygen consumption of the east coast rock lobster Panulirus homarus rubellus     

Justin O G Kemp  Peter J Britz  & Andrew C Cockcroft 《Aquaculture Research》2009,40(7):833-844

An understanding of the effect of key intrinsic and extrinsic factors on the oxygen consumption of Panulirus homarus rubellus is imperative for the development of optimized transport, holding and growout protocols. This study investigated the effect of body weight, photophase, feeding and emersion on the oxygen consumption rate of P. h. rubellus . Body weight was positively correlated to both standard and active oxygen consumption (mg O₂ h⁻¹) while body weight was negatively correlated to mass-specific standard oxygen uptake (mg O₂ g⁻¹ h⁻¹). Diurnal rhythm exhibited a strong effect on the lobsters' oxygen consumption, with average nighttime values 67% greater than those recorded during the day. This was related to activity driven by intrinsic nocturnal foraging behaviour. Feeding resulted in a classic specific dynamic action response, with postprandial oxygen consumption increasing to a peak before decreasing gradually to preprandial levels. Emersion caused a significant increase in oxygen consumption following re-immersion. Lobsters rapidly recovered to pre-emersion levels after 4 h following a 1-h emersion and after 13.3 h following an emersion period of 6 h. The implications of these results with regard to the holding/culture system and protocol design are discussed.  相似文献

RADIOGRAPHIC FINDINGS IN THE THORAX OF DOGS WITH LEPTOSPIRAL INFECTION     

D. Baumann  DVM  MS  M. Fluckiger  DVM  PD 《Veterinary radiology & ultrasound》2001,42(4):305-307

Thoracic radiographs of 4 dogs with confirmed and 1 dog with suspected leptospirosis were reviewed. In all dogs a reticulonodular pulmonary opacity was noted, affecting the entire lung in 3 and predominantly the caudodorsal lung field in 2 dogs. The radiographic lung pattern described is associated with pulmonary hemorrhage probably due to endothelial damage and vasculitis. Pulmonary manifestations in dogs with leptospirosis may be misinterpreted and attributed to neoplasia, pneumonia, edema, hemorrhage due to disseminated intravascular coagulopathy, adult respiratory distress syndrome and pulmonary thromboembolism.  相似文献
