Assay of R-Plasmid and Antibiotic Resistance Spectrum in 286 Strains of Gram-Negative Bacteria

This paper reports the results of the sensitivity test to 10 antibiotics and the assay of R-plasmid on 286 strains of Gramnegative bacteria isolated from hospital. It was found that the main prevalent resistant bacteria are pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae. Their major antibiotic resistance spectrum is:Ampicillin, Cabenicillin, Chloramphemicol. Gentamicin, Furbenicillin.
The results showed that 272 of 288 strains resisted to 1-9 antibiotics (95.1%). One-hundred and seventy-eight of 286 strains resisted to more than 4 antibiotics (62.2%). One-hundred and fifty-one of 286 strains carried R-plamid in resistant bacteria (53.3%). 13.3% resistance markers were transferred with the whole R-factor. But 86.7& resistance markers were transferred with only a part of R-factor.
