Overview

Microbiology studies microorganisms, including bacteria, viruses, fungi, parasites, and some microscopic algae. General microbiology explains their structure, growth, genetics, and interactions with hosts and the environment. Applied microbiology uses this knowledge in healthcare, food production, biotechnology, agriculture, and environmental control.
A clinical microbiology laboratory converts an appropriately collected specimen into an accurate report through a controlled sequence: collection and transport, direct examination, culture, identification, antimicrobial-susceptibility testing where required, and interpretation. Proper organization, aseptic practice, biosafety, and quality control are necessary to avoid contamination, false results, and staff exposure.
Identification traditionally combines microscopy, staining, culture appearance, and biochemical reactions. Modern laboratories also use antigen assays, nucleic-acid amplification tests, MALDI-TOF mass spectrometry, and automated systems. The method chosen depends on the organism, specimen, clinical urgency, available resources, and purpose of testing.
