WebDec 24, 2024 · The genetic absence of gene-encoding methicillin resistance, mecA, in staphylococcal species is a reliable predictor of phenotypic oxacillin susceptibility in clinical isolates and may be used to narrow therapy. At our quaternary care pediatric facility, none of the 178 (43.2%) mecA -negative isolates were oxacillin resistant. WebPhenotypic DST based on liquid automated culture has greatly reduced the time needed to generate reliable data but has the drawback to be expensive and prone to contamination in the absence of appropriate infrastructures. In the past 10 years molecular biology tools have been developed. Those tools target the main mutations responsible for DRTB ...

WebPhenotypic assays measure the ability of a virus to grow in different concentrations of ARV drugs. RT, PR, and, more recently, IN and envelope gene sequences derived from patient plasma HIV RNA are inserted into the backbone of a laboratory clone of HIV or used to generate pseudotyped viruses that express the patient-derived HIV genes of interest.
WebNov 20, 2024 · Background Colistin is used against multi-drug resistant pathogens, yet resistance emerges through dissemination of plasmid-mediated genes (mcr) or chromosomal mutation of genes involved in lipopolysaccharide synthesis (i.e. mgrB, phoPQ, pmrCAB). Phenotypic susceptibility testing is challenging due to poor diffusion of colistin …
