The results of experimental studies of the use of silver nanoparticles in tuberculosis drug-resistant pathogen

Abstract

A comparative evaluation of the effectiveness of various drugs in the treatment of experimental drug-resistant tuberculosis in mice was carried out. In 10 animals, isoniazid was used in the treatment at a dose of 50 mg/kg, to which MBT resistance was available. In the second group of 20 mice received a daily intramuscular injection of silver nanoparticles in doses of 12.5 to 125 μg/kg. In group 3, the isoniazid 20 animals at a dose of 50 mg/kg was used in conjunction with nanoparticles in the previously specified doses. The results showed that the use of silver nanoparticles in the treatment of experimental tuberculosis induced by drug-resistant pathogen increases the effectiveness of treatment. As the main criteria of the therapy effectiveness the survival of animals, the index of lesion and the seeding rate of the pathogen from parenchymal target organs were considered. A comparative histological assessment of the affected organs in different methods of treatment was carried out, which confirmed the effectiveness of the use of nanoparticles.
