Microbes like bacteria and fungi produce antibiotics. The substance
produced by a living organism, which inhibits the growth and metabolic activities of pathogenic organisms (mostly bacteria) without affecting the metabolism of host is called an antibiotic.

Penicillin, streptomycin, aureomycin and chloromycetin are some of the examples for antibiotics.

Penicillin is a well known antibiotic obtained from the blue green mold called Penicillium notatum. When it is grown in culture medium, the mycelium excretes an antibiotic substance called penicillin.

The crude penicillin is recovered, purified and dehydrated. It is effective against gram-positive bacteria like Pneumonia bacteria.

Streptomycin is obtained from the filamentous bacterium, Streptomyces griseus, an actinomycetes.

It cures urinary infections, tuberculosis, meningitis and pneumonia. Aureomycin mis obtained from actinomycetes, Streptomyces aureofaciens.

It is used as a medicine in the osteomyelitis, whooping cough and eye infections.

Chloromycetin is obtained from the actinomycete, Streptomyces
venezuelae. It kills bacillus form of bacteria and cures typhoid fever.
Aspergillus fumigatus produces antibiotic which is used against typhoid and dysentery.

Other group of microorganism like bacteria is also known
to produce many antibiotics. Bacillus subtilis produces 60 different
antibiotics.

Bacitracin is an antibiotic obtained from Bacillus licheniformis
and it is used to treat syphilis. It is useful in the control of sugar for
persons suffering from diabetes.

Through genetic manipulation, and introduction of human gene for insulin production, the bacterium E. coli is articulated to produce human insulin called “humulin”.

Root Canal Treatment

Image
Root Canal Treatment Root Canal Treatment is a modern dental procedure to save a tooth in which the pulp (the living tissue within a tooth) has died or become untreatably diseased, usually as a result of extensive dental caries. Steps involved in Root Canal Treatment (1) A hole is drilled into the crown to remove all material from the pulp chamber. The root canals are then cleaned with fine-tipped instruments. The procedure is usually monitored by X-rays. (2) The cavity is washed out, and antibiotic paste and a temporary filling are packed into it. Some days later, the filling is removed and the canals are checked for sterlity. (3) When no infection can be detected, the cavity is filled with a sealing paste and/or tapering solid “point” made of gutta – percha resin mixed with zinc and bismuth oxides. The mouth of cavity is then sealed with cement. Related Topics in Zoology: Bio Zoology All Important Topics Human Physiology Introduction Nutrition Carbohydrates Poly hydroxyaldehydes...

Eye Infections and Eye Care Eye Infections 1. Stye A stye is an acute infection of the glands located at the eyelid margin. There is swelling, pain, itching and redness in a small area at the lid margin. Treatment consists of using frequent warm compresses on the eye. (Eye Infections) 2. Conjunctivitis: Infection in the conjuctiva is called conjunctivitis. Due to the infection the invisible blood vessels within the conjunctiva become engorged. Inflammation of the conjuctiva causes redness, discomfort and a discharge from the affected eye. The most common causes for conjunctivitis are infections (in children) and allergy (in adults). (Eye Infections) 2a. Infective conjunctivitis : Most conjunctival infection are caused by bacteria (e.g staphylococci) and are spread by hand-to-eye contact or by viruses associated with a cold, sore throat, or illness such as measles, viral conjunctivitis sometimes occurs in epidemics, spreading rapidly through schools and other groups. (Eye Infections) 2b...
