- SXT (Sulfamethoxazole-Trimethoprim) Test – Principle, Procedure, Result
The SXT (sulfamethoxazole-trimethoprim) susceptibility test tells the difference between group A and B streptococci and other hemolytic streptococci. - Heat Coagulation Test of Proteins – Principles, Procedure, Resultagulation of proteins is a test in biochemistry to find whether there are proteins such as albumin and globulin found in proteins. The coagulation of proteins in reaction the heat stimulus is an typical phenomenon. The process of coagulation by heat of proteins happens in two phases; denaturation or Agglutination, or the dissociation of the protein denatured in the form it is in.
- Millon’s Test – Principle, Procedure, Result, Usesillon’s test can be described as an analytical test for the identification that the amino acid tyrosine which is the sole amino acid with the phenolic group.
- Bial’s Test- Principle, Procedure, Result, UsesBial’s test is a chemical test used for detection of pentoses (5-carbon sugars) and it is used to distinguish pentoses … Read more
- Beta (β) Lactamase Test – Principle, Procedure, ResultsMany bacteria produce a group of enzymes known as beta-lactamases that are mediated through genes in plasmids or the chromosomes. Beta-lactamase can be a constant process or it may be triggered through contact with antimicrobials. Beta-lactamases hydrolyze (and consequently inhibit) the beta-lactam ring of many Cephalosporins as well as penicillins. Beta-Lactamase Test is a rapid test to determine the presence of beta-lactamase , an enzyme that is produced by the strains from Staphylococcus aureus Neisseria gonorrhoeae, Branhamella catarrhalis as well as Haemophilus influenzae.
- Nitrocefin Test (Beta-Lactamase Test) – Principle, Procedure, UsesThe nitrocefin biochemical test is a sensitive technique for detecting beta-lactamase-producing strains of N. gonorrhoeae, H. influenzae, Staphylococcus spp, Enterococcus spp, and Moraxella (Branhamella) catarrhalis. Nitrocefin is the only reliable test for detecting beta-lactamase-producing Enterococcus spp.
- Mucic acid test – Principle, Procedure, Result, UsesMucic acid test is a biochemical test used to detect galactose and galactose containing carbohydrates such as lactose. It is … Read more
- Molisch Test – Principle, Procedure, Result, UsesMolisch’s test is a classic chemical test used for detection of carbohydrate in a given sample. It is a highly … Read more
- Rapid Furfural Test for Glucose and Fructose – Principle, Procedure, ResultRapid Furfural Test is a rapid chemical assay used to quickly distinguish between aldohexoses such as glucose and ketohexoses such … Read more
- Fehling’s Test – Principle, Procedure, ResultThis test also can differentiate between ketone functional groups and water-soluble carbohydrates.
