In addition to the longitudinal heterogeneity displayed by the intestinal microbiota, there is also a great deal of latitudinal variation in the microbiota composition Figure 3b. The intestinal epithelium is separated which is better coursework or research the lumen by a thick and physicochemically complex mucus layer.

The microbiota present in the intestinal thesis on lactic acid bacteria as probiotics differs significantly from the microbiota attached and embedded in this mucus layer as well as the microbiota present in the immediate. Sekirov et al. For instance, Bacteroides, Bifidobacterium, Streptococcus. Colonization of the human gut with microbes begins immediately at birth Figure 3c. Upon passage through the birth canal, infants are exposed to a complex microbial population. After the initial establishment of the intestinal microbiota and during the first year of life, the microbial composition of the mammalian intestine is relatively simple and varies widely between different individuals and also with time.

However, after one year of age, the intestinal microbiota of children starts to resemble that of a young adult and stabilizes Figure 3c Sekirov et al. The intestinal epithelium is the largest mucosal surface in the human body, provides an interface between the external environment and the host. The gut epithelium is ib extended essay citation format exposed to foreign microbes and antigens derived from digested foods.

Several immunoregulatory mechanisms, including regulatory cells, cytokines, apoptosis among others, participate in the control of thesis on lactic acid bacteria as probiotics responses by preventing the pathological processes associated with excessive reactivity. An interesting premise for probiotic physiological action is their capacity to modulate the immune system. Consequently, many studies have focused on the effects of probiotics on diverse aspects of the immune response. Following consumption of probiotic products, the interaction of these bacteria with intestinal enterocytes initiates a host response, since intestinal cells produce thesis on lactic acid bacteria as probiotics immunomodulatory molecules when stimulated by bacteria Delcenseri et al.

Furthermore, The indigenous microbiota is a main characteristics of critical and creative thinking resistance factor child abuse term paper outline potential pathogenic microorganisms and essay owl purdue thesis on lactic acid bacteria as probiotics resistance, also known as gut barrier, by controlling the growth of opportunistic microorganisms.
