In vitro conjugal transfer of tetracycline resistance from Lactobacillus isolates to other Gram-positive bacteria.

abstract：:Pseudomonas spp., in particular Pseudomonas fragi, are dominant in aerobically stored chilled meats. This work isolated P. fragi isolates from spoiled chicken and investigated the effect of modified atmosphere packaging (MAP, CO2/N2 30%/70%) on physicochemical properties of P. fragi isolates compared to the correspond...
