Transferable antibiotic resistance in enterobacteriaceae isolated from urinary tract infections in general practice.

138 different coliform isolates from patients with UTI in 2 General Practices in Stockport, England, showed an incidence of drug resistance of 36%: 47% of these strains transferred resistance to E. coli K12. Multiple resistance, i.e. resistance to more than 2 drugs occurred in more than a quarter of resistant isolates and sulphonamide resistance was most common. More than twice as many strains in this series (1973--74) were sulphonamide resistant compared with a previous survey (1968--70). MIC values of R+ resistant isolates were much higher with sulphonamide resistant strains than the probable urine levels during therapy, but the situation with ampicillin and tetracycline levels was variable.

[Expression of the gene for tetracycline resistance of plasmids R6 and RP4 in bacteria of the family Enterobacteriaceae].

It was found that manifestation of the tetracycline resistance gene depended on the type of the plasmid containing the gene. The tetracycline resistance gene was subject to less repression in plasmid R6 than in plasmid RP4. Sensitivity of the initial plasmid-free bacteria varied within lower dose ranges than that of the plasmid-carrying strains. Regulation of the tetracycline resistance gene manifestation in the given plasmid may change in different bacterial hosts, i.e. in different cytoplasmic environment at different gene background.

The antibody response to enterobacteriaceae and pseudomonas of patients with malignancies complicated by bacteremia.

The antibody response to the O antigens of the patients' own gram-negative bacteria causing bloodstream infection in patients with malignancies was investigated using the hemagglutination test. Of the 87 patients, 42 (48%) produced specific antibodies in significant titers. Differences were noted between the various microorganisms. Of 44 patients with E. coli bacteremia 26 (59%) had an antibody response, whereas only 5 (33%) out of 15 subjects with Pseudomonas aeruginosa infection did. The antibody response of patients with solid tumors (61%) was significantly better than that of subjects with RES malignancies (30%). Documentation of the humoral immune response of patients to isolates from blood cultures excludes laboratory contamination and supports the relevance of the isolated microorganisms. Thus, for diagnostic purposes documentation of the immunoglobulin response supplements bacteriologic findings.
