Abstract
Abstract Background/aim: Tuberculosis (TB) continues to be one of the most important infectious
diseases threatening the human health. Culture systems are used for isolation of tuberculous bacilli as
they are more sensitive than smear microscopy. The aim of the work was to evaluate the detection rate
and time of Mycobacterium tuberculosis by using the Bio FM system and mycobacteria growth indicator
tube (MGIT) system in comparison with the Lowenstein–Jensen medium.
Methods: This study was carried out on a total 60 smear acid fast bacilli positive sputum samples
obtained from patients attending the Chest Department and Outpatient Clinic of Benha University
Hospital, Benha Chest Hospital, from June 2012 to September of the same year. Patients were classified
into three groups: Group I: included 40 patients with fresh sputum smear +ve (new cases), Group
II: included 13 relapsed cases and Group III: included 7 treatment failure cases. All sputum samples
were cultured in parallel on Bio-FM, MGIT and LJ media. The mycobacterial detection rate and time
were compared.
