Foundations
5 topicsOrganism naming, bacterial structure, genetics, metabolism, host response, and normal flora logic.
Microbial Taxonomy
Microbial taxonomy explains how organisms are named, grouped, and related so students can understand why identification systems use genus, species, phenotype, and genetic relationships.
Bacterial Structure, Genetics, and Metabolism
Bacterial structure, genetics, and metabolism explain why organisms stain differently, grow on different media, cause disease, and respond differently to antimicrobials.
Host-Microorganism Interactions
Host-microorganism interactions explain colonization, infection, normal flora, opportunistic disease, immune response, and why the same organism can mean different things in different patients.
Normal Flora, Colonization, and Infection
A study page for separating expected flora, colonization, contamination, and true infection by body site and host context.
Microbial Classification Criteria
A practical map of the evidence used to group, name, and identify microorganisms: visible traits, staining behavior, growth needs, antigenic patterns, resistance behavior, and genetic data.
Clinical Lab Basics
15 topicsSafety, specimens, diagnostic methods, antimicrobial activity, QC, and clinical lab reasoning.
Clinical Microbiology Basics
Clinical microbiology uses specimens, microscopy, culture, antigen tests, serology, and molecular methods to connect a patient problem with a likely infectious cause.
Laboratory Safety
Laboratory safety protects the learner, the bench, the patient, and the community through standard precautions, containment, exposure response, and recognition of high-risk situations.
Approaches to Diagnosis of Infectious Diseases
Diagnosis of infectious diseases uses a method strategy: direct exam, culture, antigen detection, serology, molecular testing, susceptibility testing, or referral.
Evaluation of Antimicrobial Activity
Evaluation of antimicrobial activity explains how the laboratory measures inhibition, interprets susceptibility, and connects in vitro results to possible therapy.
Specimen Quality
Specimen quality determines whether a microbiology result can answer the clinical question.
Specimen Collection and Transport
Specimen collection and transport decide whether the laboratory receives the right material in a condition that can answer the clinical question.
Respiratory Specimen Quality
Respiratory specimen quality helps decide whether a sputum culture represents lower respiratory infection or mostly oral contamination.
Antimicrobial Susceptibility Testing
Antimicrobial susceptibility testing estimates whether an organism is likely to respond to an antimicrobial under defined testing conditions.
Antimicrobial Resistance Mechanisms
Resistance mechanisms explain how bacteria survive antimicrobial exposure and why certain phenotypes matter clinically.
Quality Control and Reporting Basics
A practical overview of QC, verification, critical values, corrected reports, and why microbiology reports require controlled language.
Urine Culture Basics
A bench-focused guide to urine specimen types, colony count thinking, common uropathogens, mixed growth, and when culture results need clinical context.
Blood Cultures and Sterile Body Fluids
A practical study page for interpreting positive blood cultures and sterile body fluid cultures by source, collection pattern, Gram stain, contamination risk, and urgency.
Antibacterial Drug Class Map
A study map of common antibacterial classes by main target: cell wall, protein synthesis, nucleic acid synthesis, membrane disruption, and folate pathway inhibition.
Intrinsic Resistance Patterns
A student guide to natural resistance patterns that are expected for an organism group and should not be treated as surprising acquired resistance.
AST Test Selection Logic
A practical page for deciding why some organism-drug combinations are tested, suppressed, confirmed, or avoided in antimicrobial susceptibility testing.
Core Bench Methods
14 topicsMicroscopy, stains, media, atmosphere, colony reading, and branch-point tests.
Bacteriology
21 topicsBacterial identification principles and major bacterial organism groups.
Parasitology
6 topicsStool O&P, protozoa, helminths, blood parasites, malaria, and parasite methods.
Mycology
4 topicsFungal specimens, yeasts, molds, dermatophytes, dimorphic fungi, and fungal diagnostics.
Virology
6 topicsViral structure, specimen selection, respiratory viruses, herpesviruses, hepatitis, and HIV basics.
Molecular and Immunodiagnostic Tools
6 topicsNAAT, PCR, sequencing, MALDI-TOF, immunoassays, and serology interpretation.
Bench and Exam Review
5 topicsUnknown isolate thinking, syndrome-to-test logic, exam pathways, tables, and common traps.
