Clinical microbiology focuses on detecting, identifying, and managing microorganisms that cause diseases in humans. It plays a crucial role in diagnosing infections, monitoring outbreaks, and guiding treatments. Key areas include:
Clinical microbiology aids in developing targeted therapies, ensuring effective infection control, and improving public health.
The Lysine Decarboxylase Test is a vital biochemical assay in microbiology. It identifies bacterial species based on their ability to decarboxylate the amino acid lysine. One common organism tested using this method is Enterobacter aerogenes (now reclassified as Klebsiella aerogenes). It is a gram-negative, facultatively anaerobic bacillus found in soil, water, and the human gastrointestinal … Read more
Decarboxylase Test Definition The Decarboxylase Test is a biochemical method. It is used to determine an organism’s ability to produce decarboxylase enzymes. These enzymes remove the carboxyl group (–COOH) from specific amino acids. This reaction results in the formation of amines and carbon dioxide (CO₂), leading to a rise in pH. Objectives of Decarboxylase Test … Read more
