Study Notes

Microbiology Techniques and Tests Summary

Proper biopsies are essential for correct isolation and identification of microorganisms, avoiding contamination and damage to the specimen.
Anaerobic growth conditions are crucial for certain infections like Clostridia, which require specific growth conditions.
Different types of growth media, including general purpose, enriched, selective, and differential, support the growth and identification of various microorganisms.
Eosin methylene blue (EMB) media is selective and differential, aiding in the isolation of Gram-negative microorganisms like Escherichia coli and Salmonella.
Biochemical tests in media look for the ability to ferment sugars and gas production, aiding in the identification of microorganisms.
Immunological tests, such as antibody-antigen interactions, focus on specificity and sensitivity to diagnose infections without cross-reactions or false positives.
Assay sensitivity levels vary based on the test employed, such as agglutination reaction, radioimmuno assay (RIA), and enzyme-linked immunosorbent assay (ELISA).
Neutralisation tests, like viral neutralisation and viral hemagglutination tests, assess the ability of antibodies to neutralize biological activity of pathogens or toxins, and clump surface proteins of viruses.
Fluorescent immunoglobulins (Igs) modified with fluorescent dyes are used to detect antigens on cells, with direct and indirect labelling methods.
Enzyme-linked immunosorbent assay (ELISA) utilizes enzyme labels and steps to detect antigens or Igs present in a sample.
Polymerase Chain Reaction (PCR) and LAMP are molecular techniques used for amplifying specific DNA regions and carrying out reactions at a constant temperature.
Other technologies like MALDI-TOF mass spectrometry in clinical labs can identify different bacteria based on their signature profiles.
