Mycobacteriosis (tuberculosis, leprosy, atypical mycobacteriosis, paratuberculosis, and perhaps Crohnas Disease) is the infectious disease of men and animals with the largest diffusion on earth. The infectious agents of tuberculosis are acid-resistant rod-like formed bacteria of the family Mycobacteriaceae, genus Mycobacterium. The germ was detected by Robert Koch in 1882.

Owing to the very high infectious power of pathogenic mycobacteria, early diagnosis is essential to prevent the spreading of the disease. Convergence of various approaches is necessary to control mycobacteriosis, immune reactions, and bacterial shedding being variable during the diseases.

 However, usual diagnostic procedures were up to now unsatisfactory and did not allow for distinguishing between different mycobacterial species. The illness is normally transferred by droplets of saliva from infected persons. This ELISA test kit for the determination of IgG antibodies uses a cocktail of highly pure proteins in order to determine an immune response against the bacteria in the human serum. A fresh or chronically active infection can be diagnosed by IgA and IgM tests and Anti-TB IgG Reagent which are also available.
