Abstract

Lactobacillus plantarum strains were isolated from fully ripened, white brined Bulgarian home-made cheeses. Strains were derived from phenotypically homogenous Lactobacillus group and were identified as L. plantarum based on both phenotypic and molecular identification (species-specific and multiplex PCR) methods. Heterogeneity of L. plantarum isolates was evaluated by Rep-PCR analysis. Further antimicrobial activity, antibiotic susceptibility and transit tolerance of the strains were evaluated. Most of them showed broad spectrum of activity against Gram-negative bacteria (including human pathogens) independent on the presence of organic acids or hydrogen peroxide. All strains were sensitive to amoxicillin and sulfamethoxazole/trimethoprim, resistant to clinically relevant beta -lactame antibiotics (penicillin and ampicillin) and to nalidixic acid, ciprofloxacin, streptomycin, and vancomycin. Significant variability in the sensitivity to tetracycline was noted. The tolerance to low pH, bile salts, pepsin and pancreatin at concentrations similar to those in the gastrointestinal tract was strain-dependent. The exposure to bile salts was less destructive than exposure to pH 2.0 for all tested strains. Based on their combined respo...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.
