Antibiotics and Immunity

These are strong chemical substances that are applied on spots and places where germs thrive an multiply and places where germs thrive and multiply.commonly used disinfectants are cresol, phenol, Lysol,40% formalin, lime, Bordeaux mixture, DDT etc. Precaution-all disinfectants are strong and should not come in contact with the human skin. Strong heat and boiling also destroy germs and may be called physical disinfectants.deodorants are neither antiseptics nor disinfectants.they only serve to mask a bad smell.

Antiseptics are the mild chemical and antimicrobial agents applied to living tissues to prevent infection without damaging living tissues e.g., hydrogen peroxide.

A person applies hydrogen peroxide on his wound. This is to kill anaerobic bacteria. Anaerobic bacteria cannot survive in the presence of oxygen. The hydrogen peroxide bubbling releases oxygen. Hence, due to the released oxygen, anaerobic bacteria will be killed. However, it also affects the healthy cells of the body. This in turn slows down the process of wound healing.

Hexachlorophene is a disinfectant that was commonly used in soaps and other personal care products for its antibacterial properties.

These 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. Lysol, carbolic acid (phenol), Iodine, benzoic acid, Mercurochrome, boric acid etc in dilute solution are good antiseptics. Certain antibiotic creams also serve the same purpose.

• Body's defence system produces antibodies.
  
• Antibodies are produced when an allergen or a foreign substance enters the human body by the immune system.
• It protects the body from unwanted foreign particles which enter the body.
• So, the correct answer is 'False'.

Tetracycline antibiotics are the protein inhibitors which inhibiting the binding of aminoacyl-tRNA to the mRNA-ribosome complex and prevents the translation (protein synthesis) as activated aminoacyl-tRNA bring amino acid in mRNA-ribosome complex.

• Trichoderma is a genus of fungi in the family Hypocreaceae.
• Cyclosporine A (CsA), a calcineurin inhibitor produced by the fungi Trichoderma polysporum is an immunosuppressant prescribed in organ transplants to prevent rejection.
• Hence Drug for medical treatment is obtained from organism Trichoderma.
• So, the correct answer is 'Option B'.

Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming. There are several enhanced penicillin families which are effective against additional bacteria; these include the antistaphylococcal penicillins, aminopenicillins, and the antipseudomonal penicillins. They are derived from Penicillium fungi.

Antibiotics are medicines that treat bacterial infections. They do not cure infections caused by viruses, such as the common cold or flu. Taking antibiotics when you do NOT need them can prevent them working when you DO need them.

The primary treatment is oral rehydration therapy - the replacement of fluids with slightly sweet and salty solutions rice-based solutions are preferred. Zinc supplementation is useful in children. In severe cases, intravenous fluids, such as Ringer's lactate, may be required, and antibiotics may be beneficial.

The natural way of destroying the bacterial infection is the production of the antibodies by the plasma B-cells in the body. The production of HCl also kills the harmful bacteria. The WBCs are the cells which can phagocyte and destroy the bacterial cells.

Secondary biological treatment is highly effective at reducing the organic load and bacterial content of sewage, typically achieving a reduction in the range of 80 to 98 percent.
