Bacterial Infections in Childhood

Bacteria (singular bacterium ) are any of a group of microscopic organisms that are prokaryotic , which means they lack a membrane-bound nucleus and organelles, which most other cell types have.
Bacteria are unicellular (one-celled) and may have spherical (coccus), rodlike (bacillus), or curved (vibrio, spirillum, or spirochete) bodies.
Different bacteria inhabit virtually all environments, including soil, water, organic matter, and the bodies of eukaryotes (multicellular animals).
Some bacteria are known to be beneficial to humans and the higher animals, for example in the production of buttermilk, yoghurt, cheeses, pickles, and sauerkraut; in the breaking down of vitamin K in the human gut; the breakdown of dead organisms and organic wastes, and so on, while many others are harmful. In fact bacteria are the chief cause of infectious diseases in humans.
On average, bacteria are about 1 micrometer (0.000039 inch) long and 0.5 micrometer in diameter. Bacteria are by far the most numerous lifeform on this planet. 1

The most common bacterial infections in children are the following:
