GENETIC BASIS OF ANTIBIOTIC RESISTANCE

Genetic resistance of microbes to antibiotics is due to a chromosomal mutation in the bacterial DNA or acquisition of antibiotic resistance genes on plasmids or transposons from other bacteria. Bacteria are extremely ingenious in becoming resistant to antibiotics directed towards them because they are able to regulate their drug resistance genes over time. This is […]

TYPES OF ANTIBIOTIC RESISTANCE

Bacteria have evolved to survive in diverse environments. They survive exposure to harsh chemicals including antibiotics, and they also survive difficult growth conditions. They have learned to “detoxify” harmful substances e.g. antibiotics. Antibiotic resistance can either be intrinsic or acquired. INTRINSIC (INNATE) RESISTANCE Some bacteria are said to possess innate/intrinsic resistance against antibacterial action put

ANTIMICROBIAL (ANTIBIOTIC) RESISTANCE: definition, selective pressure and clonal selection

Antibiotic or antimicrobial resistance (AMR) is a phenomenon that occurs when bacteria are not killed or inhibited by usually achievable systemic concentration of an antibiotic (drug) with normal dosage schedule and/or fall in the minimum inhibitory concentration ranges of the drug in question. It is the ability of bacteria to resist the killing or inhibitory

ANTIBIOTIC RESISTANCE

Antibiotic resistance is a phenomenon that occurs when bacteria are not killed or inhibited by usually achievable systemic concentration of an antibiotic (drug) with normal dosage schedule and/or fall in the minimum inhibitory concentration ranges of the drug in question. It occurs when bacteria change in some way that reduces or eliminates the effectiveness of

PHENOTYPIC DETECTION METHODS OF ANTIMICROBIAL RESISTANCE (AMR) IN PATHOGENIC BACTERIA

The expression “phenotypic” is from the word phenotype, which means “the observable characteristics of an organism”. It describes the physical features of an organism in terms of its morphology, motility, colour and shape amongst other noticeable attributes that are typical to a particular organism. Thus, the phenotypic detection and characterization of antimicrobial resistant genes in
