Resistance to antibiotics may occur by
-
Impermeability to the antibiotic
-
Production of increased levels of the sensitive enzyme
-
Production of a recombinant enzyme that is insensitive to the antibiotic
-
All of the above
When the microbe alters in such way that reduces the effectiveness of drug or chemicals to prevent infection and microbes multiply continuously is called as antibiotic resistance. This situation can have occurred due to a continuous supplement of particular antibiotic, production of recombinant enzymes and ineffectiveness of antibiotic. Thus, the correct answer is option D.
Which of the following was used by Alexander Flemming to prepare an antibiotic to kill bacteria?
-
Rhizopus
-
Yeast
-
Mushroom
-
Penicillium notatum
Penicillin is an antibiotic or the drug produced by the fungal species Penicillium notatum. The antibiotic is very useful in the treatment of the infections caused by Streptococcus and Staphylococcus species. This antibiotic was discovered by Alexander Flemming.
Cresol, phenol, lysol are common
-
Disinfectants
-
Antiseptics
-
Antibiotics
-
Antibodies
Disinfectants are the chemical or antimicrobial substance that are applied to non-living objects such as floor to kill microbes e.g., phenol, lysol, cresol etc.
Antiseptics can
-
Protect the body from entry of germs
-
Kill germs
-
Has no effect on germs
-
All of the above
Antiseptics are mild chemical substances which when applied on the body, kill germs. These substances are in such mild concentration that they cause no harm to the skin and body e.g., lysol, carbolic acid (phenol).
Disinfectants are
-
Biological substances
-
Enzymes
-
Chemical substances
-
Hormones
Disinfectants are the chemical or antimicrobial substance that are applied to non-living objects such as floor to kill microbes e.g., phenol.
Sulphonamides were used to treat microbial infection because they inhibit microbial growth by
-
Inhibiting wall formation
-
Competing with PABA required for synthesis of folic acid
-
Breaking naked DNA of microbes
-
Inhibiting union of ribosome subunits and preventing protein synthesis
-
Antiseptic
-
Photolysis

(A)Antiseptic is capable of preventing microbial infection
Agents used to kill microbes on living surfaces are called
-
Disinfectant
-
Tranquilizers
-
Antiseptic
-
Both A and C
Disinfectants are antimicrobial agents, that are applied to non-living objects to destroy microorganisms.
Tranquilizers are drugs used to reduce anxiety, fear, tension, agitation and mental disturbances.
Antiseptics are the mild antimicrobial chemical substances, that are applied to living tissue/skin to reduce the possibility of infection, sepsis.
Thus, the correct answer is option C.
Antiseptics are
-
Mild chemical substances
-
Strong chemical substances
-
Weak catalysts
-
Strong enzymes
Antiseptics are the mild chemical, antimicrobial substance. It is make mild so that it cannot harm the tissues. It is applied to tissues or skin to reduce the infection e.g., hydrogen peroxide.
Antiseptics are
-
Taken orally
-
Intravenously
-
Applied on skin
-
All of the above
Antiseptics are mild chemical substances which when applied on the skin to kill germs. These substances are in such mild concentration that they cause no harm to the skin and body. Lysol, carbolic acid (phenol). Thus, the correct answer is option C.
