A. Fernandezastorga et al., DISINFECTANT TOLERANCE AND ANTIBIOTIC-RESISTANCE IN PSYCHROTROPHIC GRAM-NEGATIVE BACTERIA ISOLATED FROM VEGETABLES, Letters in applied microbiology, 20(5), 1995, pp. 308-311
A total of 330 strains of psychrotrophic non-fermenting Gram-negative
bacteria isolated from vegetables were studied. In spite of the wide r
ange of antibiotic resistance occurring, less than 10% showed resistan
ce patterns which included mezclocillin-ticarcillin-gentamicin or ceft
izoxime-norfloxacin. Reductions of > 5 log(10) in the numbers of cfu w
ere found when these strains were exposed for 30 min to a quaternary a
mmonium compound (1% w/v).
