The trial product is an Intradermal test to diagnose tuberculosis infection and nontuberculosis mycobacteriosis in combination with other methods. The trial will include 2 stages (stage I, II). At stage I 5 healthy volunteers will be consequently included in each group to evaluate tolerance and reactogenicity. Time required to evaluate the tolerance and reactogenicity for the first 5 volunteers in each group is less than 3 days. If no SAEs which have a possible, probable and definite causal relationship with the product administration are observed in more than three volunteers from each group, the remaining volunteers will be allowed to take part in the trial. At stage II 20 healthy volunteers will be included in each group. Each volunteer will be assigned a two-digit randomization number.
Primary objective of the trial is to study the safety and tolerability of the Recombinant tuberculosis allergen in standard dilution in healthy volunteers after a single dose.~Additional trial purpose: evaluation of the product reactogenicity.
