Summary

THE SURFACES OF BEEF AND CHICKEN SAMPLES WERE INOCULATED WITH A MIXTURE OF A DONOR (RESISTANT TO TETRACYCLINE, STREPTOMYCIN, CHLORAMPHENICOL, AMPICILLIN, NEOMYCIN AND SULPHONAMIDE), AND A RECIPIENT STRAIN OF ESCHERICHIA COLI. MEATS WERE MAINTAINED AT 293 AND 277 K (20 AND 4 DEG C) AND SAMPLED DAILY. TRANSFER OF ANTIBIOTIC RESISTANCE COULD NOT BE DEMONSTRATED AT EITHER TEMPERATURE. THE RECIPIENT STRAIN SURVIVED WITHOUT SIGNIFICANT GROWTH AT 277 K, BUT FAILURE TO TRANSFER ANTIBIOTIC RESISTANCE AT 293 K WAS CONSIDERED TO BE DUE TO THE SESSILE GROWTH OF THE ORGANISMS ENCLOSED IN A DENSE GLYCOCALYX, PRECLUDING CLOSE CONTACT BETWEEN THE ORGANISMS.
