A Review on Clinical Aspects of Antibiotics Therapy in Treatment of Tuberculosis

The primary cause of tuberculosis (TB) in humans is Mycobacterium tuberculosis (M. tuberculosis), which causes hundreds of thousands of deaths and millions of infections globally. The community bears a heavy financial burden as a result. Bovine TB, commonly referred to as zoonotic TB, is caused by Mycobacterium Bovis, which infects cattle in contrast to M. tuberculosis. By handling ill animals, consuming unpasteurized dairy products, and being exposed at work, people can get zoonotic tuberculosis. In Nepal, there is little awareness of the link between zoonotic tuberculosis in humans and cattle. According to the study, exposure to infected cattle is one of the risk factors that lead to the development of tuberculosis in humans in Nepal. There are both human and animal participants in the study. To begin with, a retrospective matched case-control investigation was carried out at the National Tuberculosis Centre for Tuberculosis (NTC), Bhaktapur, Nepal. Interviews were conducted with 290 individuals (equal numbers of TB cases and control participants) to gather data on occupational, behavioural, and sociodemographic hazards, including exposure history associated to cattle. Second, cross-sectional research was conducted among the cattle that belonged to the patients who had been diagnosed with tuberculosis. To identify M. Bovis infection in cattle, ELISA, fast antibody testing, and comparative tuberculin skin testing were employed concurrently. Human TB development risk variables included history of cattle exposures (OR = 3.9, 95% CI: 2.1–7.4, p = 0.001), prior history of TB (OR = 7.9, 95% CI: 3.0–20.6, p < 0.001), and smoking (OR = 4.6, 95% CI: 2.1–10.0, p < 0.001). Twelve animals (9.76%, 95% CI: 5.37–16.76, p < 0.0001) out of the 123 cattle sampledELISA test, 7 (5.7%, 95% CI: 2.52– 11.80, p < 0.0001), and 46 (37.4%, 95% CI: 28.97– 46.62, p = 0.007) were found to be positive by the tuberculin test. There was a high degree of intertest agreement between the ELISA and tuberculin (κ = 0.72, 95% CI: 0.48–0.95, p < 0.01). According to this study, human TB can develop as a result of exposure to infected cattle as well as sociodemographic risk factors.
