The virus, which means poison in Latin, is the micro-organisms (microorganisms)
cause infectious diseases such as AIDS, smallpox, hepatitis, influenza, polio, and
rabies. He can only be seen by electron microscopy, and by itself is an inanimate
object. Live virus in human cells, animals, plants, and bacteria that live. In
these cells is able to breed with fertile, then master of his host, and cause
disease. Although there are also “silent virus,” which does not show its existence
despite many years of silence in the host cell. Immunization using a vaccine that
is widely used way to prevent virus infection. Experts have been trying to develop
antiviral drugs, but has not been too successful.
Bacteria are in Greek, bacterion, meaning a small stick, is a single-celled
plants; magnitude of 1-10 micrometers (thousandths of a millimeter). He can be
found at low temperatures or hot temperatures, both in the air, soil, water, or
symbiosis in living organisms such as humans, animals, or plants.
To date about 1,600 known species of bacteria, 200 of which are pathogenic
bacteria that cause infections in humans. There are two major classes of bacteria,
saprophyte (living on dead organic matter) and simbiot (who live and get food on
the human, animal and plant life). In humans, the bacteria simbiot include any of
the digestive tract and skin, and divided into three groups, namely mutualistic
(helps in physiological processes while living on the host), commensal (living on
the host without causing disease), and potential pathogens or opportunism (can
cause disease when the host body’s resistance is reduced, for example in
postoperative major or severe illness, like cancer and AIDS). Many infections
caused by bacteria can be prevented through immunization with vaccines or
treatment with antibiotics. Fungi also cause infections in humans are very tiny
and can only be seen with a microscope. Of the thousands of species of fungi that
are known at this time only less than 50 species that can cause infections in
humans and animals, and not until the 15 species that can cause fatal disease in
humans. Infections due to fungi can occur on the surface of the skin, the skin,
mucous membranes, or organs like the lungs. Generally, prevention and treatment of
fungal infections has been known and available. So also in the form of worms and
protozoan parasites that cause infection.
The cause of the failure of antimicrobial therapy
– Drugs, administration or provision of the wrong path;
– Resistance / tolerance of the drug;
– Inadequate dosing or poor patient compliance;
– Medicines that do not reach the microorganisms, such as intracellular
– Microorganisms that were not detected.
– Rnasalah administration of drugs, such as incompatibility with the infusion
solution or administration of antibiotics used during meals / after meals.
– Foreign object in the body, such as catheters, artificial heart valve prosthesis
– Pus or hematoma or abscess formation.
