Abstract:
We examined diseases occurring farmed Whitmania pigra(L.) in Hebei province in the aspect of situation of disease,clinical symptoms and pathological changes.In addition,the molecular identification were conducted to representative strain,the 16S rRNA gene was sequenced and compared with that of related strains,molecular phylogenetic tree was constructed.The results showed that the disease was infected by Aeromonas hydrophila.Pure cultures of 10 strains have the same serotype.Selected representative strain was proved to be the corresponding primitive causal agent of the disease by artificial infection experiment to healthy Whitmania pigra(L.).Antibiotic sensitivity of the isolates to used thirty-seven antimicrobial agents showed that the tested strains were high sensitive to cefotaxime et al.,were sensitive to streptomycin et al.,were resistant to oxacillin et al.
