UOMS-AST allows free physical access ( e.g., by standard pipetting) to the system and label-free, single-cell resolution optical access.
WebRapid Phenotypic AST. Methods for rapid phenotypic AST are based on the evaluation of bacterial growth curves after exposure to antimicrobial agents, over a significantly shorter period in comparison with conventional AST. MIC values and susceptibility categories are deduced from the growth curves via dedicated algorithms. WebPhenotypic AST is usually based on the detection of bacterial growth differences with or without antibiotics in liquid culture or on solid agar plates.
