OBJECTIVES The aim of this study was to compare the current screening methods and to evaluate confirmation tests for phenotypic plasmidal AmpC (pAmpC) detection. METHODS For this evaluation we used 503 Enterobacteriaceae from 18 Dutch hospitals and 21 isolates previously confirmed to be pAmpC positive. All isolates were divided into three groups: isolates with 1) reduced susceptibility to cef...
Parallel phenotypic evolution, the independent evolution of the same trait in closely related lineages, is interesting because it tells us about the contribution of natural selection to phenotypic evolution. Haldane and others have proposed that parallel evolution also results from a second process, the similarly biased production of genetic variation in close relatives, an idea that has receiv...
although candida albicans is the most common etiologic agent of candidiasis, c. dubliniensis, has been emerged, as another pathogen resembles c. albicans in many phenotypic aspects and noted for its in vitro potential for fluconazole resistance. since there was no evidence of any report about detection of this organism in iran, this study was designed to use of five different tests for identifi...
methicillin-resistant staphylococcus aureus (mrsa) is the main cause of hospital infection emerged over the last decades. rapid detection of mrsa is important for patient care and proper usage of infection control. detection of meca genes (encoding resistance to methicillin and other similar antibiotics) and nuc genes (encoding staphylococcal thermostable nuclease) by pcr method is now consider...
Strains of Pseudomonas stutzeri and related denitrifying bacteria were compared in their phenotypic properties and mean deoxyribonucleic acid (DNA) base composition. On the basis of this comparison and of in vitro DNA hybridization experiments, it was concluded that, using practical diagnostic tests, no more than two nomenspecies can be recognized within the group. One, P. stutzeri, was extreme...
We have made a detailed phenotypic characterisation of the type strains of 21 species within the genus Halomonas and have also studied any possible intraspecific variation of strains within H. eurihalina, H. halophila, H. maura and H. salina. We used 234 morphological, physiological, biochemical, nutritional and antimicrobial susceptibility tests. Nutritional assays were carried out using both ...
