13. Routine application of the polymerase chain reaction for detection of Mycobacterium tuberculosis in clinical samples.
AIM--To investigate the use of the polymerase chain reaction (PCR) in the routine laboratory for the detection of Mycobacterium tuberculosis in clinical samples. METHODS--Samples were divided and processed separately for the detection of M tuberculosis by microscopy, culture and PCR. After DNA extraction, PCR was performed with primers specific for the inser

14. Ehrlichia chaffeensis: a Prototypical Emerging Pathogen
Ehrlichia chaffeensis is an obligately intracellular, tick-transmitted bacterium that is maintained in nature in a cycle involving at least one and perhaps several vertebrate reservoir hosts. The moderate to severe disease caused by E. chaffeensis in humans, first identified in 1986 and reported for more than 1,000 patients through 2000, represents a prototy

15. Evaluation of Gen-Probe Amplified Mycobacterium Tuberculosis Direct Test and Roche PCR-microwell plate hybridization method (AMPLICOR MYCOBACTERIUM) for direct detection of mycobacteria.
We evaluated the clinical utility of an rRNA amplification-based Gen-Probe Amplified Mycobacterium Tuberculosis Direct Test (AMTD) system and a PCR-based Roche AMPLICOR MYCOBACTERIUM system for direct detection of Mycobacterium tuberculosis, M. avium, and M. intracellulare. Of the 422 sputum samples from 170 patients, 137 (121 of M. tuberculosis, 14 of M. av

16. Notification of tuberculosis: how many cases are never reported?
BACKGROUND: Notification of tuberculosis is essential for local contact tracing and for assessing the national incidence of tuberculosis. The accuracy of notification figures is uncertain. This study examined the notification rates of all patients diagnosed as having tuberculosis at two hospitals in the East End of London over five years. METHODS: In a retro

17. The association of gonorrhoea and syphilis with premature birth and low birthweight.
OBJECTIVE--Provide evidence from prospective data that Neisseria gonorrhoeae may be an important cause of premature delivery and low birth weight in areas with high prevalence of genital infections. SETTING--Department of Obstetrics and Gynaecology, Kalafong University Hospital, Pretoria, South Africa in collaboration with the Departments of Microbiology and
