Answer 1

56)Here to demonstrate sterility in autoclave biological indiactors like heat stable bacterial endospores.Here the ans is d

57)A surgical mask ability to control infection is measured interms of its filtration ability.Here the ans is d

58)ethylene oxide is widely used for gas sterillization of surgical equipment.Here the ans is d

59)here the erythromycin interferes with protein synthesis by blocking 50s subunits of ribosomes.Here the ans is a

60)sulfanilamide is antibiotic drug which act as competitive inhibitor for enzyme dihydropteroate synthetase for PABA(PARA AMINO BEZOIC ACID).Here the ans is b

61)Here the correct option is b

62)Here the ans is a because bacteria bortonella henselae is aerobic

63)lyme disease is caused by bacteria borrilia borgdoferi .It is characterized by fatigue,flu like symptoms,bulls eye pattern and characteristic skin rash called erythema migrans
