*2.8.2.4* Lactobacillus reuteri *strain*

*L. reuteri* is the probiotic strain of the probiotics *L. reuteri*, is a well-known probiotic. *L. reuteri* ATCC 55730 colonizes the stomach effectively and can reduce the occurrence of watery diarrhea associated with rotavirus. In addition, it recently showed effectiveness in the treatment of acute diarrhea with oral rehydration in

children from 6 to 36 months of age [84]. A Indrio [85], research shows that *L. reuteri* DSM 17938 treatment has lowered stomach distension, expedited gastric emptying, and reduced regurgitation in children with normal gastroesophageal reflux. A recent study shows that this strain also has a favorable effect on the medication of baby colic if employed in several clinical studies or as a therapy for prophylaxis.

#### *2.8.3* Saccharomyces *spp. with probiotic properties*

*Saccharomyces* genus contains several yeasts like: *Saccharomyces cerevisiae* that is used for the preparation of wine, bread, beer, *Saccharomyces bayanus* is used to produce wines, and *Saccharomyces boulardii* utilized in medicine as a probiotic [86].

*S. boulardii* is frequently advertised as a lyophilized probiotics to treat diarrhea and retains an excellent safety reputation [87]. Most reports show that *S. Boulardii's* clinical advantages are reducing diarrhea duration regardless of causation and thus reducing the social and economic benefits associated with hospitalization. *S. boulardii* dispensation has had a positive effect on the prevention and treatment of retroactive inflammatory bowel disease and moderate symptoms of ulcerative colitis [88] patients with irritable bowel syndrome. Current *Clostridium difficile* pseudomembranous colitis infection can also be drastically reduced through the administration of *S. boulardii* regular dosages together with standard antibiotics. No malformations were reported in the previously referred examination of probiotic safety during pregnancy [89]. It should be borne in mind, however, that *S. boulardii* can lead to fungal diseases or localized infections in immunocompromised people or in other patients.

### *2.8.3.1 Escherichia coli strains with probiotic properties*

Although it is known mainly for its highly virulent serotype (e.g., *E. coli* O157:H7), *E. coli* is a very common lower gut inhabitant and even a probiotic strain is known to be *E. coli* Nissle 1917; *E. coli* genus belongs in a Gram-negative family called Enterobacteriaceae (EcN). As previously mentioned, it has been proven that constipation [90] and inflammatory bowel disease were treated with other probiotics in 1917 [91]. This strain could also alleviate gastrointestinal disorder, ulcerative colitis, Crohn's disease and even colon cancer.
