ERIC-PCR genotyping of Pseudomonas aeruginosa isolates from haemorrhagic pneumonia cases in mink.

BACKGROUND

Pseudomonas aeruginosa is a significant pathogen of mink and the cause of haemorrhagic pneumonia, an acute fatal disease in farmed mink.

RESULTS

Among 90 P. aeruginosa isolates from haemorrhagic pneumonia in mink from 16 farms in Shandong province, China, 43 genotypes were identified by enterobacterial repetitive intergenic consensus PCR (ERIC-PCR), with a diversity index of 0.96. The most prevalent ERIC-PCR types were type 18, found in 16 isolates, and type 39, found in 15 isolates. Four serotypes were detected, with serotype G (55.6 per cent) being the most frequent.

CONCLUSIONS

These results showed that there was a high degree of clonal diversity among mink P. aeruginosa clinical isolates in this study.
