| multiplex pcr for bla(ctx-m) & bla(shv) in the extended spectrum beta lactamase (esbl) producing gram-negative isolates. | phenotyping is commonly used for detection of extended spectrum beta lactamase (esbl) production in gram-negative isolates. esbls are mainly coded for by three important genes, namely bla(tem), bla(shv) and bla(ctx-m). in this study we used a multiplex pcr as a rapid method to identify two common genes (bla(ctx-m) & bla(shv)) responsible for extended spectrum beta lactamase production in members of enterobacteriaceae family isolated from different clinical samples from a specialty hospital at ch ... | 2008 | 19052344 |
