Microbial samples are small quantities of microorganisms, such as bacteria, fungi, or viruses, collected for scientific study. These samples can be taken from various environments, including soil, water, or human bodies, to analyze the diversity and behavior of microbes. Researchers use these samples to understand microbial roles in ecosystems, health, and disease. The collection and analysis of microbial samples are essential in fields like microbiology, environmental science, and medicine. Techniques such as culturing, sequencing, and microscopy help scientists identify and characterize these microorganisms, leading to discoveries that can improve public health and environmental management.
