Isolation and Screening of Novel Isolates of Bifidobacteria from Human Milk as Potential Probiotic with Antidiarrheal Activity

Bifidobacteria are gram-positive, anaerobic, catalase negative rods of various shapes (short, regular, thin cells with pointed ends, coccoidal regular cells, long cells with slight bends or protuberances) or a variety of branching (pointed, slightly bifurcated, club-shaped or spatulated extremities), single or chains of various arrangements (in star-like aggregates or disposed in "V" or "Y" or else "palisade" arrangements [11].Their genome GC content varies from 42 mol% to 62 mol% [12].Bifidobacterium have several beneficial effects on the health of host such as immunomodulation, elimination of procarcinogens, production of vitamin, prevention of diarrhea and intestinal infections, alleviation of constipation, production of antimicrobials against harmful
