[QUOTE="Mataracy, post: 128748, member: 28733"] Many types of living organisms can invade and damage the human body. BACTERIA These are single- celled forms of life,visible under the microscope. They exist all around us, in the air, in the earth, in the mouth and in the bowel. They are not all harmful or disease producing(pathogenic), Most are nonpathogenic and indeed may be beneficial. Bacteria normally present in the bowel many prevent the growth of pathogenic organisms and they help to produce vitamins. VIRUSES Viruses are too small to be seen under the microscope. Theylungs only survive inside living cells since they depend on the nutriment of the cells for rhe it growth and replication. Viruses are resistant to the action of antibiotics. FUNGI(MYCOSES) Numerous fungi or moulds exist in the soil, in decaying vegetation and in the excreta of birds. Fungi can be regarded as a form of vegetation and sometimes are antagonistic to the growth of bacteria- penicillin is derived from one such mould. Other fungi, known as mycoses, can infect the skin,the mouth(commonly known as thrush), and the lungs PROTOZOA These are single-celled parasites, biggervthan bacteria and changing form during their life cycle. Malaria and amoebic dysentery are two widespread tropical diseases caused by protozoa. METAZOA Thesr are many-celles organism, the majority visible to the naked eye. They include such parasite as lice, scabies and intestinal worms. All these are what causes infection and though some are not harmful but many of them can as well damage human body. [/QUOTE]
