Cognitive development is Jean Piaget's theory. Through a series of stages, Piaget proposed four stages of cognitive development: the sensorimotor, preoperational, concrete operational and formal operational period.
The versatility of Bifidobacterium longum as a lactic acid microorganism is reflected in its capacity to resist under harsh conditions such as stomach acid, bile, pH fluctuations, and gastrointestinal passage.
Bifidobacterium Longum INTRODUCTION Bifidobacterium longum, also commonly referred to a B. longum, is a non-pathogenic probiotic that is found naturally in the gastrointestinal tract (GIT) and the vagina.As a probiotic, B. longum may provide health benefits to individuals as B. longum works to prevent disease.. longum, as well as other types of âgoodâ bacteria, have what is considered a symbiotic relationship with human beings.
