urologists, while some probiotic organisms may reduce the recurrences of bladder
cancer or oxaluria, no probiotics can be recommended widely to prevent UTI at
present (Reid and Bruce 2006).
10.6.5 Reproductive System
Reproductive health problems of women are not the same between the developed
and developing countries. However, they share a common link in microbial involvement. Lactobacillus is the dominant type of bacteria present in the vagina. It is
affected by several factors like dietary intake, menstrual status, sexual practices,
socioeconomic status and genetics. The problems that are seen among females are
problems concerning conception, preterm labor, sexually transmitted infections,
malnutrition and environmental challenges. Probiotics (live microorganisms) in
adequate amounts can offer better reproductive health benefit. The development of
the fetus is related to maternal nutrition. Vaginal Lactobacilli produces isomers of
alpha-linolenic acid and other neurochemicals like by-products which go to the
uterus and placenta through bloodstream from the gut and has a vital role in fetal
development. The gut-brain signaling and the effect of micro-organisms on memory, anxiety like brain functions, have been shown to influence fetal development.
When Probiotic lactobacilli is given during pregnancy, this can lead to immune
modulation and reducing allergic responses. These probiotic interventions though
not proven clinically, can help reduce the pregnancy related risk factor.
Lactobacilli influence different membrane structures involved in pregnancy as it
controls the adherence junction protein regulation which is vital for epithelial barrier function (Azad et al. 2018). This membrane integrity is needed for successful
blastocyst formation, retention of the amnion, chorion and placenta. Lactobacillus
reuteri released histamine resulted in increased cAMP levels. Evidence show that
probiotics stop the downstream MEK/ERK MAPK signaling through protein kinase
A, and depressed the TNF production by regulation transcription. TNF is involved
in preterm labor induction (Reid et al. 2013).
10.6.6 Immune System
In 2015, the World Allergy Organization (WAO) released probiotics usage guidelines for prevention of allergy. Gut micro biota is an important factor in the increasing occurrence of immunity-related disorders like asthma, inflammation, atopy,
musculoskeletal disorders and liver fibrosis. It influences the physiology of host and
gives rise to new targets therapeutically. Probiotics suppresses pathogenic bacteria
in the gut with the activity of macrophages of peritoneum and spleen. In malnutrition processes, the probiotic administration contributes to restore the thymus histology and stimulates the adaptive immune response.
