In Vitro Selection of Probiotic Lactobacilli:

The problem of choosing criteria for the in vitro selection of lactobacilli to be used as health-promoting, probiotic ingredients, in food and pharmaceutical preparations, was apparent even in the original works of Metchnikoff, who first proposed the therapeutic use of these bacteria. In the last decade, a consensus has been reached by scientists on some criteria, with particular attention bein...

Assessment of Antibiotic Resistance in Probiotic Lactobacilli

Probiotics are live microorganisms that confer a health benefit on the host when administered in adequate amounts (Food and Agriculture Organization of the United Nations-World Health Organization Working Group, 2002). Many microbial species have probiotic properties, but those most commonly used are lactobacilli (Salminen et al, 1998; Caplice & Fitzgerald, 1999; Leroy & De Vuyst, 2004). Lactob...

Antibiotic Susceptibility of Potentially Probiotic Vaginal Lactobacilli

OBJECTIVE To study the antimicrobial susceptibility of six vaginal probiotic lactobacilli. METHODS The disc diffusion method in Müeller Hinton, LAPTg and MRS agars by the NCCLS (National Committee for Clinical Laboratory Standards) procedure was performed. Due to the absence of a Lactobacillus reference strains, the results were compared to those of Staphylococcus aureus ATCC29213. Minimal In...

Characterization of intestinal lactobacilli as putative probiotic candidates.

AIMS To use antioxidative activity and antagonistic properties of lactobacilli against selected pathogens and members of the normal microflora as a basis for screening probiotic candidates. METHODS AND RESULTS Antagonistic activity of lactobacilli against target bacteria in both microaerobic and anaerobic environments was tested. Production of antagonistic metabolites (ethanol, hydrogen perox...
