A rapid test was developed for identification of polymyxin resistance in nonfermenting bacteria. This detects viable cells after growth a medium containing defined concentration colistin.
Urinary tract infections (UTIs) are the most common bacterial in humans. They mainly caused by Escherichia coli and other Enterobacterales for which increasing resistance to antibiotics particular β-lactams is extensively reported. The detection of β-lactam phenotypes currently time-consuming (18 h). Hence, treatments given without any results antibiotic susceptibility testing may involve broad-spectrum antibiotics. A biochemical diagnostic test has been developed rapidly evaluate production...
Microbiology is a difficult topic to teach given that the objects of study are mostly invisible learner. The majority university students beginning their training in biology more interested natural can be seen with naked eye. Nonetheless, micro-organisms key components biosphere and good microbiological background required for thorough sciences. Lectures still common teaching format universities. However, it passive learning no longer considered most adequate approach situations. Instead,...
Bacteria have evolved many strategies to spare energy when nutrients become scarce. One widespread such strategy is facultative phototrophy, which helps heterotrophs supplement their supply using light. Our knowledge of the impact that behaviors on bacterial fitness and physiology is, however, still limited. Here, we study how a representative genus Porphyrobacter, in aerobic anoxygenic phototrophy ancestral, responds different light regimes under nutrient limitation. We show survival...
The SuperCAZ/AVI medium was developed for screening ceftazidime-avibactam (CZA) resistance among Gram-negative bacteria (Enterobacterales and Pseudomonas aeruginosa). It evaluated using 50 CZA-susceptible 42 CZA-resistant isolates. Its sensitivity specificity of detection were 100%. Excellent performance the also observed by testing spiked stools, with lower limit ranging from 101 to 102 CFU/ml. This provides opportunity detect isolates regardless their mechanisms.
We developed a novel culture-based test, the Rapid CAZ/AVI NP for rapid identification of ceftazidime/avibactam susceptibility/resistance in Enterobacterales. This test is based on glucose metabolization upon bacterial growth presence defined concentration (128/53 μg/mL). Bacterial visually detectable by red to yellow color change phenol, pH indicator. A total 101 well characterized enterobacterial isolates were used evaluate performance. showed positive percent agreement 100% and negative...
The rapid ResaImipenem/Acinetobacter NP test was developed for the identification of carbapenem resistance among Acinetobacter baumannii isolates. principle this is based on reduction resazurin (a viability colorant) by metabolically active bacterial cells, hence detecting growth, in presence a defined concentration imipenem chosen to be slightly above that defining (6 μg/ml). Bacterial growth visually detected color change from blue (resazurin) purple or pink (resorufin product). A total...
