R factor-mediated antibiotic resistance in Serratia marcescens.
Nineteen of 39 multiresistant strains of Serratia marcescens isolated from clinical sources transferred antibiotic resistance to Escherichia coli or Klebsiella pneumoniae recipients. Marcesins and/or phage prevented effective resistance transfer to E. coli and attempts to select marcescin-resistant mutants of the E. coli recipient strain were unsuccessful. Transfer of resistance was demonstrate...
متن کاملAntibiotic - Resistant R . E . AMBROSIO , Serratia marcescens Infection Hospital
Over a 12-month period, 74 isolates of Serratia marcescens were obtained from various sources at Tygerberg Hospital. The majority of these isolates were from catheterized patients with urinary tract infections, and were non-pigmented and resistant to all antibiotics tested, excepting amikacin and neomycin. All isolates transferred resistance to tobramycin, gentamicin and tetracycline by conjuga...
متن کاملThe role of Serratia marcescens porins in antibiotic resistance.
The outer membrane permeability of Serratia marcescens was studied by comparing porin-deficient mutants with their parental strains. Omp1-deficient strains were selected by moxalactam resistance, whereas mutants lacking the Omp2 porin were obtained by experimental infection with the SMP2 phage, whose primary receptor is the Omp2 porin. The role of porins was demonstrated in quinolone accumulati...
متن کاملR factors from Serratia marcescens.
In recent years, Serratia marcescens has become established in certain localities as an agent of hospital infection and cross-infection (Clayton & von Graevenitz, 1966; Wilfert, Barrett & Kass, 1968; Davis, Foltz & Blakemore, 1970; Wilkowske, Washington, Martin & Ritts, 1970). In general, strains of S. marcescens isolated from infective lesions differ from those from other sources in being non-...
متن کاملAntibiotic resistance patterns of clinical isolates of Serratia marcescens.
Antimicrobial susceptibility patterns of 102 clinical isolates of Serratia marcescens from three medical centers were studied by using disk sensitivity and agar dilution methods. The least resistance was demonstrated against gentamicin, nalidixic acid, chloramphenicol, and sulfisoxazole, all of which inhibited more than 80% of the strains. Cephalothin was completely ineffective, and more than 9...
