[Biological characterization and prospects of application of a new bifidobacterial strain as an ingradient of probiotics].
The study was dedicated to investigation of a bifidobacterial strain, isolated from a healthy chick, its biological properties and lectins produced by the strain; a restrictive analysis of the chromosomal DNA was conducted as well. Presumably B. gallinarum was identified. The strain displayed adhesive, lectinic and antagonistic activities; it was resistant to the leading chemotherapeutic pharmaceuticals and antibiotics, and, when given to chicks, it had probiotic effect. The study identified a set of lectins binding phosphorylated mannan, with isoelectric points in the pH interval of 4 to 8; the set differed from the sets of lectins of other bifidobacteria.
