- Mechanism of action of DNA inhibitors antibioticsPractice Case study p. 224 part: Tuberculosis (TB) in indigenous populations. Lily was a recent science graduate of the University of Alberta and was 11 months into her 12 - month Master of Science in Global Health degree, at Dalhousie University. This relatively new program was created to provide the multidisciplinary training required of scientists working to meet the complex challenges of global public health issues. The University had partnered with the National Collaborating Centre for Indigenous Health (NCCIH) and that was why Lily now found herself doing her Global Health Field Practicum in the Northern Territories, working on a study of drug resistant TB infections among Innuit communities. The different communities included in her research were close to 7000 individuals, with multiple diagnosed cases of TB. And while she was grateful that drug-resistant TB in Canada remained below the global average (Public Health Agency of Canada, 2019), she was cognizant of the possibility…A pathogenic bacteria ferments for survival in your patient producing a swollen, dark discolored leg due to muscles degradation and gas-filled distension on the skin.

- What is your personal comment on the relevance of this application? Refer to the study below https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7824784/ Riboswitches as Drug Targets for Antibiotics Vipul Panchal* and Ruth Brenk*Choose the false statement: Penicillin is a ß lactam which inhibits bacterial growth by inhibiting DNA polymerase. O Resistance to ß lactamase inhibitors arises when bacteria duplicate the ß lactamase gene. O B lactamase inhibitors are prescribed together with antibiotics like penicillin in order to combat resistance to these antibiotics. Question 10 Choose the false statement below: OUsing multiple antimicrobials in combination is an ineffective strategy because they generally are redundant in effect and the chance of drug resistance will be increased. O Because of its complex structure and multiple binding sites, the ribosome is the target for multiple types of antibiotics. O Choice of an antimicrobial agent may be dependent upon the material treated as well as the susceptíbility of the microbe.Give three reasons why liposomes/nanoparticles are attractive drug delivery system for recombinant protein preparations?
