Article Synopsis
- * A study identified genes for two β-glucosidases and four endo-1,4-β-glucanases in the marine bacterium Microbulbifer sp. Strain GL-2, with high gene expression during stationary growth and induction by cello-oligosaccharides.
- * The gene for one enzyme, Cel5A, was cloned and shown to have wide-ranging activity (10-40 °C and pH 6-8), indicating potential for industrial use, unlike other similar enzymes which perform poorly at lower temperatures or alkaline conditions
The house fly is known to be a vector of antibiotic-resistant bacteria (ARB) in animal farms. It is also possible that the house fly contributes to the spread of ARB and antibiotic resistance genes (ARGs) among various environments. We hypothesized that ARB and ARGs present in marine fish and fishery food may gain access to humans via the house fly.

We report here for the first time a higher rate of the sulfonamide-resistance gene in marine bacterial isolates compared with other genes. Among four sulfonamide-resistance genes (, , , and ), was most abundant (45%) in 74 sulfonamide-resistant marine isolates by PCR screening.

We herein report an ICE from Shewanella halifaxensis isolated from fish intestine with a similar structure to both a clinical bacterial ICE and marine bacterial plasmid. The ICE was designated ICEShaJpn1, a member of the SXT/R391 family of ICEs (SRIs).

Methods: Resistant bacterial rate was measured by culture method, and copy numbers of macrolide-ARGs, mef(A), erm(B), mph(B), mef(C)-mph(G), and mobile genetic elements (MGEs) traI and IntI1 were quantitated in environmental DNA.
