Molecular epidemiology investigations in 8 Romanian outbreaks of rabbit Pasteurellosis by pulsed-field gel electrophoresis

摘要

Pasteurellosis is one of the most serious diseases of rabbits, with considerable economic loss in large production units and unfavourable prognosis for rabbits with clinical signs. The rabbits can develop health problems caused by Pasteurella, especially if they are unwell or stressed, and clinical pattern and lesions can be heterogeneous. The identification and quantification of risk factors are difficult and dependent by subjectivity of pet owner. This study is focused on pet rabbits that were diagnosed with pasteurellosis. The major stress factors identified in our study were: phonic stress, excessive manipulation, transport stress and improper feeding. Clinical and lesion data collected in this study support the heterogeneity of rabbit Pasteurella infections, previously described in several papers. The etiological study was split in following stage of diagnostics: classical bacteriological investigations and comparison of the profiles of pulsed-field gel electrophoresis bands. The study revealed that P. multocida strains isolated on pet rabbits have a high variability.
