title: Phage types, antibiograms and R-plasmids of Klebsiella and Enterobacter isolated from hospital environment and food.
abstract: Four-hundred and twenty-two Klebsiella strains and 294 Enterobacter strains were isolated from direct or indirect environment of hospitalized patients, from foodstuffs, foods, culinary utensils and staff in hospital and in catering establishments. Of Klebsiella, the species K. aerogenes (76.5%) of Enterobacter, the species E. cloacae (77.6%) occurred the most frequently in all specimens. Klebsiella strains were typable in 68.5%; 53.1% of the Enterobacter strains were sensitive to phage. Most of the untypable Klebsiella and Enterobacter strains and the multiresistant strains originated from screening in hospitals. Sensitive bacteria as well as those resistant to one or two antibiotics may be potentially dangerous for the patient consuming them, since they may become multiresistant due to R-plasmid transfer.
