Microorganisms play a crucial role in human health, influencing various biological processes. While some microbes cause diseases, many are essential for maintaining overall well-being. Beneficial bacteria in the gut, such as Lactobacillus and Bifidobacterium, aid digestion, synthesise vitamins, and support immune function. The human microbiome, a complex ecosystem of microorganisms, helps protect against harmful pathogens by outcompeting them for resources.

Microorganisms are also vital in medicine. Antibiotics, derived from fungi and bacteria, combat infections, while probiotics promote gut health. Additionally, genetically engineered bacteria contribute to the production of insulin and vaccines. However, imbalances in microbial populations can lead to health issues like infections or autoimmune diseases.
Understanding the role of microorganisms is essential for advancements in healthcare and biotechnology. Students seeking Biology Assignment Help can explore this topic further to gain deeper insights into the relationship between microbes and human health.
