Studies on the Tuberculin Reactivity of Tuberculin-Active Peptide

Studies on Tuberculin Fever

In a search for the source of the circulating endogenous pyrogen (EP) that mediates tuberculin-induced fever, tuberculin was incubated in vitro with various tissues of rabbits sensitized by intravenous infection with BCG. Evidence was obtained that tuberculin specifically stimulates cells in the blood of sensitized rabbits to generate pyrogen in vitro, whereas both lymph node and spleen cells f...

1Department of Internal Medicine; 2Department of Family Medicine, King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Received: 25/10/01; accepted: 14/02/02 ABSTRACT Tuberculosis is both a nosocomial and an occupational infection. The prevalence of positive tuberculin skin reactions at King Abdulaziz University Hospital, Saudi Arabia, was investigated by testing 298 health care workers. C...

Tuberculin reactivity after neonatal percutaneous BCG immunisation.

A total of 348 neonates of Asian ethnic origin were given percutaneous BCG vaccination using a multiple puncture head. Fifty five (15.8%) were tuberculin negative when tested 6-9 weeks after vaccination, a significantly higher proportion than after intradermal vaccination. The number of abscesses after vaccination was however significantly lower.

Current tuberculin reactivity of schoolchildren in the Central African Republic

BACKGROUND The tuberculin skin test (TST) is the recommended method for screening for Mycobacterium tuberculosis infection in many countries. We used this technique to assess bacillus Calmette-Guérin (BCG) status and to estimate the current prevalence and annual rate of latent tuberculosis infection in schoolchildren in the Central African Republic. METHODS Two tuberculin units of 0.1 ml puri...
