Please give me answers for those multiple choices. Thank you

Answer 1

Answer 1: (D) Caused by highly virulent organism. ( The pathogenicity of an organism its ability to cause disease is determined by its virulence factors)

Answer 2: (B) Peptidoglycan (peptidoglycan cell wall composed of disaccharides and amino acids gives bacteria structural support)

Answer 3: (D) All of the above. ( Antibiotic may cause resistance and also have major side effects if taken for long duration.)

Answer 4: (A) Staphylococcus aureus. (Staphylococcus aureus, resulting in a painful swollen area on the skin caused by an accumulation of pus and dead tissue.)

Answer 5: (C) A non- living surface commonly touched by people. ( fomite is objects or materials which are likely to carry infection, such as clothes, utensils, and furniture.)

Answer 6: (A) Indwelling catheter

Answer 7:(E) All of the organism which causes disease.
