Introduction: The relationship between gastric microbiota and acid-dependent diseases is currently not fully studied. The study is based on a review of the literature to analyze and reflect the available data on the interaction of gastric microbiota and acid-dependent diseases, as well as brain-gut diseases.
Methods: The survey was performed by analyzing data from Medscape, PubMed, Elsevier. The articles analyzed are in English, Romanian, Russian, published in the last 10 years. Data on the composition (landscape) of the gastric microbiota and their influence on acid-dependent diseases and digestive diseases in general were reflected.
Results: The research reflected that in addition to Helicobacter pylori infection, the landscape of the gastric microbiota in the acid stomach (with low pH) is not sterile and includes other types such as: Proteobacteria, Firmicutes, Actinobacteria, Bacteroidetes, Fusobacteria. At the same time, current methods document a bacterial load of 10-10 CFU/mL in the colon, which is much higher than in the stomach, where it reaches 10-10 CFU/mL. H. pylori influences the diversification of the non-H.pylori gastric microbiota; Decreased diversification increases the risk of carcinogenesis. The aspects of the role of H. pylori in functional dyspepsia, named after the Maastricht Consensus V - H. pylori dyspepsia, were also demonstrated. The taxonomic profiles (Philum-level, Genus-level) of the gastric microbiota require the study of the interrelationships with acid-dependent diseases, as well as the feedback.
Conclusions: The study shows that the stomach is not a sterile organ and in addition to H. pylori there are 5 other types of gastric microbiota, which are interrelated with acid-dependent diseases and digestive disorders and vice versa. This issue requires a comprehensive approach.

Cadmium (Cd) pollution poses an important problem, but limited information is available about the toxicology effects of Cd on freshwater invertebrates. We investigated the accumulation, oxidative stress, microbial community changes, and transcriptomic alterations in apple snails ) under Cd stress. The snails were exposed to the 10 μg/L Cd solution for 16 days, followed by a 16-day elimination period.

With the growing demand for sheep, the sheep farming industry has developed rapidly. However, lamb diarrhea, a disease with high mortality rates, significantly hampers the industry's growth. Traditional antibiotic treatments often disrupt the Intestinal microbiota, induce antibiotic resistance, and cause adverse side effects, highlighting the urgent need to develop alternative therapies.

Studies on the gastric microbiota associated with gastric precancerous lesions remain limited. This study aimed to profile the gastric mucosal microbiota in patients with -negative precancerous lesions. Gastric mucosal samples were obtained from 67 -negative patients, including those with chronic gastritis (CG), intestinal metaplasia (IM), and dysplasia.

Probiotics are beneficial to humans and animals and often used for regulating immunity, intestinal microbiota balance, and animal growth performance. Donkey husbandry has boomed in China in recent years and there is an urgent need for probiotics effective for improving donkey health. However, studies on potential probiotic strains isolated from donkeys are scarce.

Modern hyperprolific sows are increasingly susceptible to health challenges. Their rapid growth rates predispose them to locomotor disorders, while high metabolic demands, reduced backfat thickness, and increased protein accretion heighten their vulnerability to heat stress and dystocia. Additionally, prolonged farrowing negatively affects the oxidative and inflammatory status of these females.
