TEMPORAL DEVELOPMENT OF RESISTANCE TO PULMONARY TUBERCULOSIS IN SWISS ALBINO MICE

Temporal Development of Resistance to Pulmonary Tuberculosis in Swiss Albino Mice

The course of pulmonary tuberculosis was followed in control and BCG-vaccinated mice. Resistance was evaluated by determining the numbers of virulent mycobacteria recovered from the organs at various intervals after airborn infection. A limited but significant retardation of growth of challenge bacilli was observed in both pulmonary and splenic tissues of successfully vaccinated animals. This r...

Measurement of Resistance to Experimental Tuberculosis in Albino Mice

Enhanced resistance against experimental tuberculosis was acquired by albino mice after peritoneal vaccination with living BCG. Prolongation of life was used as a measure of resistance against massive intravenous challenge infection. The average degree of prolongation of life was found to be directly related to the size of the vaccinating dose. The ultimate numbers of BCG bacilli recovered from...

A STUDY OF MYCOBACTERIUM TUBERCULOSIS DRUG RESISTANCE IN PULMONARY TUBERCULOSIS

Tuberculosis remains a major public health problem in both developing and developed countries. Drug-resistant tuberculosis is an increasing health problem and serious challenge to tuberculosis (TB) control programs. Information about the susceptibility pattern of Mycobacterium tuberculosis isolates against anti-tuberculosis drugs is an important aspect to TB control. The objectives of the s...

Radioprotective Efficacy of Lutein in Ameliorating Electron Beam Radiation-induced Oxidative Injury in Swiss Albino Mice

Background: Lutein, a carotenoid compound, has previously been studied for its antioxidant and medicinal properties as well as the moderate protection it confers against gamma radiation. This study aimed at evaluating the effects of lutein against radiation-induced hematological and biochemical changes in mice.Methods: The optimized dose of the compound was orally administered for 15 days, and ...
