| analysis of variable genomic loci in white spot syndrome virus to predict its origins in procambarus clarkii crayfish farmed in china. | variable genomic loci were examined in 4 white spot syndrome virus (wssv) isolates (08hb, 09hb, 08js and 09js) from procambarus clarkii crayfish collected from jiangsu and hubei provinces in china in 2008 and 2009. in orf75, sequence variation detected in the 4 isolates, as well as in isolates sequenced previously, suggested that wssv might have segregated into 2 lineages since first emerging as a serious pathogen of farmed shrimp in east asia in the early-mid 1990s, with one lineage remaining i ... | 2011 | 22013750 |
| genetic diversity and virulence potential of staphylococcus aureus isolated from crayfish (procambarus clarkii). | staphylococcus aureus, a commensal and a pathogenic bacterium, causes a wide variety of diseases in humans and animals with a high impact on public health and the livestock industry. the risk of zoonotic transmission to humans highlights the need to understand the molecular ecology of s. aureus in foods. in this study, we obtained 25 s. aureus isolates from 39 crayfish samples in hubei, china. pcr was applied for detection of presence of virulence and methicillin resistance genes in the pathogen ... | 2017 | 27761619 |
