АннотацияDespite the more than a century-old history of using the Pirquet and Mantoux tests for the rapid diagnosis of tuberculosis, the ef efctiveness of determination of Koch’s bacillus infection remains relatively low. This fact is related to the peculiarities of the immune response of warm-blooded animals to Mycobacterium infection. Tuberculin is used to demonstrate delayed type hypersensitivity reactions to mycobacterial antigen in animals or humans, as seen in individuals previously infected with Mycobacterium or vaccinated with BCG. Therefore a skin test can be performed repeatedly and, in case of positivity, still be diagnostic of earlier mycobacteria infection or previous vaccination with BCG. In this work, the interaction of tuberculin with the phagocytizing cells of the immune system was studied. Rabbit immunization with tuberculin complexed with gold nanoparticles gave rise to a tuberculin-specif ci antiserum. The colloidal-gold–tuberculin conjugates did not inhibit the respiratory activity of rat peritoneal cells. Dark-f ield light and confocal laser microscopies showed that the gold nanoparticles penetrated the intracellular spaces of the peritoneal macrophages in vitro, possibly relieving in part the toxic ef efct produced by tuberculin
