[Study of immune response in Warao children from communities with high tuberculosis prevalence].

The present study was carried out in a Warao childhood population with extremely high tuberculosis (TB) rate of 3190/100,000 in 0-15 years old children. One hundred seven serum and saliva samples were tested, 32 from patients with active TB (27 positive and 5 negative for the tuberculin skin test, TST) and 75 apparently healthy contact children (45 positive and 30 negative for the TST). The innate, immunoglobulin and cellular responses were studied.
