Microbial Influence on Animal Health: The Role of Gut Microbiota, Dysbiosis, and Probiotic Interventions

Microbes are integral to animal health, influencing various physiological processes and contributing to overall well-being. This review article explores the multifaceted roles of microbes in animal health, focusing on their diverse types, including bacteria, fungi, viruses, archaea, and protozoa. The gut microbiota is highlighted for its crucial functions in digestion, nutrient absorption, and immune system modulation. The article also examines the significance of skin, respiratory, and reproductive tract microbiota in maintaining health and preventing disease. Beneficial microbes and probiotics are discussed for their mechanisms of action, including immune modulation, pathogen exclusion, and metabolic contributions.
Microbial dysbiosis, or microbial imbalance, is identified as a key factor in the development of various diseases. This condition results from disruptions in microbial communities due to factors such as antibiotic use, poor diet, and environmental stressors. The review details common diseases linked to dysbiosis, including gastrointestinal, skin, respiratory, and metabolic disorders. Diagnostic techniques, including high-throughput DNA sequencing and quantitative PCR, are emphasized for their role in detecting and understanding dysbiosis.
The review concludes with a discussion on the importance of maintaining balanced microbial communities for health and the potential of targeted therapeutic approaches, such as probiotics, to restore microbial balance and improve health outcomes. Continued research is essential for advancing our understanding of microbe-host interactions and developing effective strategies for disease prevention and management.
