Abstract
The aim of this study was to assess the utility of Xpert assay, Ziehl-Neelsen (ZN) staining, and Mycobacteria Growth Indicator Tube (MGIT™) culture for diagnosis of pediatric pulmonary tuberculosis from gastric aspirate (GA) samples and to compare Xpert assay and ZN staining with MGIT rapid liquid culture. GA samples from 210 nonexpectorating children, aged between 6 months to 12 years, presenting to the pediatric out-patient department (OPD) with clinical suspicion of tuberculosis (TB) were collected. The samples were tested by GeneXpert, ZN staining, and MGIT liquid culture. GeneXpert is a more sensitive method for rapid and early diagnosis of pediatric TB when compared with microscopy.
