Abstract

A multicenter study was conducted to obtain "in vitro" chloramphenicol and colistin susceptibility data on multiresistant hospital bacterial pathogens in Slovak Republic. During the period of April-June 2001, 628 clinical bacterial multiresistant isolates from patients with serious infections were selected in 10 hospitals and tested to a large scale of antibiotics by means of a microdilution method. The strains expressed either a significant resistance phenotype (ESBL, MRSA, CoNMRS, MLSB/c, efflux in Ps. aeruginosa), or were resistant to one or more preparations in at least half of reliable unrelated antibiotic groups (beta-lactams, aminoglycosides, quinolons, macrolides). Both chloramphenicol and colistin retained significant "in vitro" activity against many multiresistant hospital bacterial pathogens. The highest activity of chloramphenicol was documented for isolates of Stenotrophomonas maltophilia (76,5 % susceptible, MIC50 = 4 mg/L, MIC90 = 16 mg/L) and of Staphylococcus aureus (76,2 % susceptible, MIC50 = 8 mg/L, MIC90 = 16 mg/L). In tested Pseudomonas aeruginosa (82,5 % susceptible, MIC50 = 2 mg/L, MIC90 = 16 mg/L) and Stenotrophomonas maltophilia (88,2 % susceptible, MIC50 = 1 mg/L, MIC90 = 8 mg/L) isolates colistin rep...Continue Reading

Aminoglycosides (ASM)

Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside. Discover the latest research on aminoglycoside here.

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.
