Experimental Chemotherapy of Mycobacterial Diseases
Abstract
Experimental chemotherapy of tuberculois provides the opportunity to assess, in vivo, the antimicrobial activity of a newly developed drug in comparison with that of existing drugs, its antagonistic, additional, or synergistic activity when it is given in combination with other drugs, its ability to prevent the selection of mutants resistant to the other drugs, and, finally, its ability to sterilize the lesions of the experimentally infected animals. However, to obtain reliable information, experimental chemotherapy should be performed in an adequate model. Because of its exquisite susceptibility to Mycobacterium tuberculosis infection, the guinea pig has been long been the animal of choice for detecting the presence of a tiny number of tubercle bacilli in a clinical specimen. It has also been used in experiments to assess the airborne transmission of tuberculosis and the impact of chemotherapy on the transmission (1), the comparative virulence of different strains of M. tuberculosis (2), the protective value of M. bovis Bacille—Calmette—Guérin (BCG) against a subsequent challenge with M. tuberculosis (3), and the comparative antituberculosis activity of several drugs and drug combinations given daily or intermittently (4,5). In spite of its numerous advantages, the guinea pig has not been used extensively as an animal model for the experimental chemotherapy of tuberculosis because its size makes it difficult to be used in large numbers, its metabolism is different from that of humans, and, finally, it has a high sensitivity to intercurrent infections.
