Welcome to this portal dedicated to microbiology, in its many forms. From medicine to ecology, from viruses to bacteria, we are all involved in this area yet so poorly understood. Who has never used the term "microbe" in a pejorative sense? These organizations can not only be the cause of disease! . . Yet only a few microorganisms are pathogenic to humans (in view of their immense diversity)! Most are harmless, some even indispensable for our digestion! Discover this rich and exciting field through a synthetic that will undoubtedly shed new light on many of us so it ca: clinical microbiology books . . Foraminifera are protozoans appeared in the Cambrian. The test, comprising one or more rooms (or loculus or boxes), is equipped with one or more foramen (hole). They were living benthic or planktonic (particularly in the photic zone). Their size generally ranges from 38 microns to 1 mm (some may exceed 10 cm) . .

In biology, specifically in microbiology, a culture is a method for the multiplication of microorganisms such as bacteria, fungi and parasites, which prepares an optimal medium to support the desired process. A crop is used as a fundamental method for the study of bacteria and other microorganisms that cause diseases in human and veterinary medicine. A microorganism can be grown in a liquid medium or on a solid medium of agar. The culture media containing different nutrients that range from simple sugars to complex substances such as blood or meat extract broth. To isolate or purify a bacterial species from a sample of many types of bacteria, is grown on a solid medium in which cells multiply that no change of location; after several reproductive cycles, each individual bacteria generated by binary fission macroscopic colony of tens of millions of cells similar to the original. The culture media, to be used and ensure that the results obtained from them are reliable, they must meet the following requirements:. . . Microbiology is the branch of biology responsible for the study of microorganisms, small living beings also known as microbes. It is the science of biology devoted to study the organisms that are only visible under a microscope: simple prokaryotes and eukaryotes. They are considered all living microbes microscopic, they may consist of a single cell (unicellular) and small cell aggregates formed by cells equivalent (without differentiation), they may be eukaryotes (cells with nuclei) such as fungi and protists , prokaryotes (cells without nuclei defined) as bacteria]. But traditional microbiology has focused especially among bacterial pathogens, viruses and fungi, other microorganisms leaving in the hands of parasitoologÃa and other categories of biology. .
