Causes and spread of infection Micro-organisms that cause infections are known as pathogens. They may be classified as follows: Bacteria: minute organisms about one-thousandth to five-thousandths of a millimetre in diameter. They are susceptible to a greater or lesser extent to antibiotics. Viruses: much smaller than bacteria and although they may survive outside the body for a time they can only grow inside cells of the body. Viruses are not susceptible to antibiotics‚ but there are a few

Bacterial infections are normally treated with a cause of antibiotics Viruses are made up of genes and proteins that spread throughout the body by invading the body’s own cells so they can reproduce and multiply in the body. They use the body’s cells as a host because they are unable to multiply on their own. They are normally spread directly from human to human. Fungi like to grow in warm‚ moist
