Beta-lactams, Tetracyclines and Sulfonamides 

Colloidal Gold      ·   Food Safety        ·      BTS 3-in-1

Beta-lactams, tetracyclines, and sulfonamides are classes of antibiotics widely used in veterinary medicine to treat bacterial infections in livestock. Residues of these antibiotics can be detected in animal-derived products such as meat, milk, and eggs. Improper use of antibiotics or insufficient withdrawal periods may result in the presence of beta-lactams, tetracyclines, and sulfonamides in food products, posing potential risks to human health, including allergic reactions and antimicrobial resistance. Hence, rigorous monitoring and control of antibiotic residues in food-producing animals and their products are imperative to ensure food safety and safeguard public health.

Beta-lactams, Tetracyclines
& Sulfonamides SUMMARY

Beta-lactam antibiotics contain a beta-lactam ring in their chemical structure. Beta-lactam antibiotics family includes penicillin derivatives (penams), cephalosporins and cephamycins (cephems), monobactams, carbapenems and carbacephems. Most beta-lactam antibiotics function by inhibiting biosynthesis of the cell wall. Beta-lactam antibiotics are usually applied for prevention and treatment initiated by susceptible organisms.

Tetracyclines are a class of antibiotics used as a treatment of infection caused by susceptible microorganisms including both gram-positive and gram-negative bacteria. Tetracycline antibiotics could also be applied to infection initiated by chlamydiae, protozoans and rickettsiae. Tetracyclines are widely used in veterinary medicine to prevent malaria or treatment of anthrax.

Sulfonamides, an important class of synthetic antimicrobial drugs, is commonly used as a broad-spectrum antibiotic drug for the treatment of both human and animal bacterial infections. Sulfonamide antibiotics are not readily biodegradable and could possibly cause various side effects and allergic reactions. Sulfonamide antibiotics function effectively against gram-positive and certain gram-negative bacteria. Sulfonamide antibiotics function by competing with p-aminobenzoic acid (PABA) during the synthesis of folic acid which is essential for DNA replication, which inhibits bacterial DNA growth and cell division or replication.

sulfonamides, tetracyclines and beta-lactams antibiotics residues are founded in fresh raw cow's milk.

Bioartron Beta-lactams, Tetracyclines and Sulfonamides (BTS 3-in-1) Rapid Test kit contains mouse monoclonal anti-beta-lactams, anti-tetracyclines and anti-sulfonamides antibody-colloidal gold conjugate pre-dried in the sealed microwells.  Beta-lactams-BSA, tetracyclines-BSA and sulfonamides-BSA conjugate antigen (on test zone) and goat anti mouse IgG (on control zone) are coated and immobilized on a reaction membrane.   


The principal of Bioartron Beta-lactams, Tetracyclines and Sulfonamides (BTS 3-in-1) Rapid Test is a solid phase, competitive inhibition immuno-chromatographic assay, in which beta-lactams-BSA, tetracyclines-BSA and sulfonamides-BSA would compete respectively with beta-lactams, tetracyclines and sulfonamides that may be present in fresh raw milk sample to be tested, for limited antibody binding sites. When the absorbent pad (sample end) is soaked with the liquid sample in the microwell, the liquid sample will then migrate via capillary action toward the test window where the test reaction occurs. The absorbent pad (sample end) should be removed when observing to avoid further absorption.
