Multiplex PCR

StarStarStarStar

Simultaneously amplifying multiple genes in a single PCR reaction. In microbiology, this is used for the detection of co-infections or identifying multiple pathogen targets at once.

StarStarStarStar

Northern Blot

StarStarStarStar

Similar to Southern blot but for RNA. It allows the study of gene expression in microbiology by detecting RNA transcripts associated with particular bacterial or viral genes.

StarStarStarStar

Metagenomics

StarStarStarStar

Study of genetic material recovered directly from environmental samples. In microbiology, metagenomics allows for the discovery of new microbes and analysis of microbial communities in their natural habitats.

StarStarStarStar

Southern Blot

StarStarStarStar

Transfer of DNA fragments from an agarose gel to a membrane and detection using a labeled probe. In microbiology, it's used to identify specific DNA sequences related to pathogens or for genetic fingerprinting.

StarStarStarStar

LAMP (Loop-mediated Isothermal Amplification)

StarStarStarStar

A strand-displacement method for amplifying DNA with high specificity under isothermal conditions. Used in field diagnostics in microbiology due to its simplicity and the ability to detect pathogens quickly without sophisticated equipment.

StarStarStarStar

RNA-seq (RNA Sequencing)

StarStarStarStar

High-throughput sequencing of RNA to study gene expression profiles. In microbiology, RNA-seq is used to examine the response of microorganisms to various conditions, including infection scenarios.

StarStarStarStar

DNA Sequencing

StarStarStarStar

Determining the exact sequence of nucleotides in a DNA molecule. In microbiology, it is used for characterizing strains of bacteria or viruses at the molecular level for outbreak tracking or treatment tailoring.

StarStarStarStar

CRISPR-based Diagnostics

StarStarStarStar

Leveraging CRISPR-Cas systems for detecting genetic sequences specific to pathogens. It has been transformative in rapid and precise identification of infectious agents in microbiology.

StarStarStarStar

Polymerase Chain Reaction (PCR)

StarStarStarStar

Used to amplify DNA sequences for identification of pathogens. It is used in microbiology for detecting the presence of specific bacteria or viruses by amplifying their genetic material.

StarStarStarStar

ELISA (Enzyme-Linked Immunosorbent Assay)

StarStarStarStar

Use of enzyme-linked antibodies to detect specific antigens. In microbiology, ELISA is primary for detecting the presence of pathogens or quantifying antibodies in patient samples as a measure of exposure.

StarStarStarStar

RFLP Analysis (Restriction Fragment Length Polymorphism)

StarStarStarStar

Use of restriction enzymes to cut DNA into fragments followed by gel electrophoresis. In microbiology, RFLP can help in genetic fingerprinting of pathogens to understand epidemiology and drug resistance patterns.

StarStarStarStar

Fluorescent in situ Hybridization (FISH)

StarStarStarStar

Identification and localization of specific DNA/RNA sequences in cells or tissue sections using fluorescent probes. FISH is used in microbiology to detect and localize specific microorganisms within environmental or clinical samples.

StarStarStarStar

Reverse Transcription PCR (RT-PCR)

StarStarStarStar

Converts RNA into DNA before amplification. Utilized in microbiology to detect RNA viruses like HIV or influenza by first reverse transcribing their RNA into DNA.

StarStarStarStar

Recombinant DNA Technology

StarStarStarStar

Genetic engineering to insert DNA fragments into vectors for expression or analysis. In microbiology, recombinant DNA technology is used for vaccine development, creating diagnostic tools, and studying gene function in pathogens.

StarStarStarStar

DNA Microsatellite Analysis

StarStarStarStar

Assessment of regions of repetitive DNA for high variability. This technique helps microbiologists understand genetic diversity and population structure of microorganisms.

StarStarStarStar

Mass Spectrometry in Microbiology

StarStarStarStar

Identification and quantification of molecules by mass. In microbiology, mass spectrometry is utilized for identifying bacterial species, studying protein interactions, and detecting biomarkers for infectious diseases.

StarStarStarStar

Western Blot

StarStarStarStar

Transfer of proteins from a gel to a membrane and detection using antibodies. Microbiologists use it to identify specific proteins related to microorganisms, which can be indicative of infection or immune response.

StarStarStarStar

Isothermal Nucleic Acid Amplification

StarStarStarStar

DNA amplification at a constant temperature. Microbiologists use this technique for its simplicity and rapidity in detecting pathogens, particularly in point-of-care settings.

StarStarStarStar

Microarrays

StarStarStarStar

Use of probes to simultaneously assess expression of multiple genes. In microbiology, microarrays can be used for pathogen identification, antimicrobial resistance detection, and community profiling in complex samples.

StarStarStarStar

Real-Time PCR (qPCR)

StarStarStarStar

Allows quantification of DNA or RNA sequences in real-time during the PCR process. In microbiology, it is used for measuring the load of pathogens in a sample, aiding timely diagnosis and treatment decisions.
