Inter- and intraspecies plasmid-mediated transfer of florfenicol resistance in Enterobacteriaceae isolates from swine.

abstract：:Cotton flowers in replicate plots in two fields near Phoenix, Ariz., were tagged in June at the beginning of the flowering period. Flowers or developing bolls from these tagged flowers were inoculated on the involucral (bracteal) nectaries with dry spores of Aspergillus flavus. The bolls were harvested as they matured...
