Pyrazinamide is an important drug used in anti tubercular treatment which helps in killing old and semi dormant bacilli which are not metabolically active. Drug susceptibility tests are routinely performed before initiating multidrug drug resistant tuberculosis treatment. However, many Tuberculosis laboratories do not undertake drug susceptibility testing of Pyrazinamide as it is difficult to p...

1. Staining and culture. Current methods of specimen staining and culture used for M. tuberculosis are acceptable for most NTM species. The preferred methodology includes fluorochrome staining and culture in a liquid medium as well as on Middlebrook 7H10 or 7H11 agar. Species for which special growth conditions are needed include those responsible for cutaneous disease, which need lower incubat...

background: streptococcus agalactiae, also known as group b streptococcus (gbs) is a commensal organism in the urogenital tract and rectum in approximately 25% of the healthy adult female population. the bacterium is the leading cause of bacterial meningitis, pneumonia, and sepsis in human infants. materials and methods: our study was performed over a three - month period from april to june 201...

background and objectives: the emergence and spread of multidrug resistant (mdr) and extended spectrum β-lactamase (esbl) producing strains reduces the number of effective drugs that can be used for treatment. the aim of this study was to evaluate the susceptibility profile of enterobacteriaceae isolated from utis, specifically mdr and esbl producing strains, to fosfomycin and other antibiotics...
