Ну а где еше просвешаться. Мне правда еше удается слушать лекции ведуших ученых в етой области.
Для тех кто понимает английский цитата из научной статьи обупликованной в хорошо цитируемом микробиологическом журнале:
Until the culture of Helicobacter pylori (Marshall and Warren 1984), the human stomach was considered to be microbiologically sterile because of factors including low pH and digestive enzymes. The stomachs of mammals other than humans are frequently colonized by bacteria other than Helicobacter, and lactobacilli and streptococci appear to be especially prevalent (Roach et al. 1977; Fuller et al. 1978; Yin and Zheng 2005). However, there may be a greater microbial diversity in the human stomach than had previously been thought. Using 16s rRNA sequencing Bik et al. (2006) detected 128 different bacterial phylotypes, including lactobacilli, in 23 human gastric biopsies. Roos et al. (2005) successfully cultured lactobacilli from gastric biopsies from healthy humans, and identified and described four new Lactobacillus species, L. gastricus, L. antri, L. kalixensis and L. ultunensis. To date, these species have not been further described. We hypothesized that it might be possible to isolate other lactobacilli from the human gastric mucosa and that this niche might represent a reservoir for bacteria with beneficial traits. Lactobacilli that could survive the hostile gastric environment could have applications as probiotics, or in fermentations at particularly low pH to which formic acid is added such as silage (Nadeau et al. 2000) or yoghurt (Cotter and Hill 2003).
