Microbiology (in Greek micron = small and biologia = studying life) is the study of microorganisms, including viruses, viroids, prions, prokaryotes and simple eukaryotes (e.g. molds and fungi). Microbes represent ideal model systems for study due to the fact that many can be grown quickly and easily in genetically uniform cultures (e.g. agar), which allows for the production of biological materials (e.g. protein or DNA) in reasonable quantities quickly, safely and inexpensively. However, viruses, viroids, and prions cann ...

Some examples of susceptible and resistant organisms, from the Amoxil® Approved Product Information (GSK, 2003), are listed below. Amoxicillin - Susceptible Gram-positive organisms. Streptococcus spp., Diplococcus pneumoniae, non β-lactamase-producing Staphylococcus spp., and Streptococcus faecalis. Amoxicillin - ...

Salmonella are Gram negative bacteria. In a clinical laboratory, they are usually grown isolated on blood agar, CLED agar, XLD agar or DCA agar. On blood agar, they form moist colonies about 2 to 3 mm in diameter. They do not ferment lactose. Salmonella taxonomy is complicated. Currently (7 Dec 2005), there are two species within the genus: S. bongori (previously subspecies V) and S. enterica (formerly called S. choleraesuis), which is divided into six subspecies: I—entericaSee also:

Staphylococcus aureus appears as a Gram-positive coccus, in grape-like clusters when viewed through a microscope and as large, round, golden-yellow colonies, often with β-hemolysis, when grown on blood agar plates. Hence, the word "aureus" which means gold in latin. S. aureus can be differentiated from most other staphylococci by the coagulase test. S. aureus is coagulase-positive, while most other staphylococci are coagulase-negative. S. aureus is also catalase positive and thus able to convert hydrogen peroxide ...

The disease is caused by the parasite Borrelia, which has well over three hundred known genomic strains but is usually cultured as Borrelia burgdorferi, Borrelia afzelii and Borellia garinii. Different Borrelia strains are predominant in Europe and North America. The disease has been found to be transmitted to humans by the bite of infected Ixodes ticks. Not all ticks carry or can transmit this particular disease. It should also be noted that in a few cases the disease may also be transmitted ...

Agar is a galactose polymer (or agarose) obtained from the cell walls of some species of red algae or seaweed (Sphaerococcus euchema) and species of Gelidium, chiefly from eastern Asia and California. It is also known as Kanten, Agar-Agar, or Agal-Agal (Ceylon Agar). Chemically, agar is a polymer made up of subunits of the sugar galactose; it is a component of the algae's cell walls. Dissolved in hot water and cooled, agar becomes gelatinous; its chief use is as a culture medium for microbiological work. Other uses are as a lax ...

A microorganism or microbe is an organism that is so small that it is microscopic (invisible to the naked eye). Microorganisms are often illustrated using single-celled, or unicellular organisms; however, some unicellular protists are visible to the naked eye, and some multicellular species are microscopic. The study of microorganisms is called microbiology. Microorganism - Micro-organisms and unicellular organisms. Micro-organisms may be found almost anywhere in the taxonomic structure. Unice ...

Germ is an informal term for a disease-causing organism, particularly bacteria (as in germ warfare). One of the first people to postulate that some diseases were caused by the presence of some kind of very small 'seed' (the original meaning of 'germ') that germinated or multiplied in the body to produce the disease was Ignaz Semmelweis, a Hungarian doctor, practising in an obstetrics ward in the 1840s. He noticed that the death rate of the impoverished women attended by the nurse midwives was many times less than that of ...

Blood culture is microbiological culture of blood. It is employed to detect infections that are spreading through the bloodstream (bacteremia, septicemia). Blood culture - Method. About 30 ml of blood is taken through venipuncture and injected into two "blood bottles" with specific media for aerobic and anaerobic organisms. Care needs to be taken that the bottles are not contaminated with bacteria from staff members or other patients. To that end, the patient's skin and the top of the blood bottles a ...

Blood tests are laboratory tests done on blood to gain an appreciation of disease states and the function of organs. Since blood flows throughout the body, acting as a medium for providing oxygen and other nutrients, and drawing waste products back to the excretory systems for disposal, the state of the bloodstream affects, or is affected by, many medical conditions. For these reasons, blood tests are the most commonly performed medical tests. Blood is obtained from a patient by venipunct ...

Carl Richard Woese is an American microbiologist famous for defining the Archaea (a new domain or kingdom of life) in 1976 by phylogenetic taxonomy of 16S ribosomal RNA, a technique pioneered by Woese and which is now standard practice. He was also the originator of the RNA world hypothesis in 1967, although not by that name. He was born in Syracuse, New York, on July 15, 1928. Woese is currently a professor of Microbiology a ...

Broadly defined, geobiology is an interdisciplinary field of scientific research that explores interactions between the biosphere and lithosphere or atmosphere. Investigators from numerous fields are involved in geobiologic research, including, but not limited to, such disciplines as: paleontology, microbiology, mineralogy, biochemistry, sedimentology, genetics, physiology, geochemistry (organic and inorganic), and atmospheric science. One major subdiscipline of geobiology is geomicrobiology, an area of study that focuses on investiga ...

Unobservables are entities whose existence, nature, properties, qualities or relations are not observable. In the philosophy of science typical examples of "unobservables" are atomic particles, the force of gravity, causation and beliefs or desires. However, philosophers also characterize all objects—trees, tables, other minds, microbiological things and so on to which humans ascribe as t ...

A Vortex Mixer is a simple device used most commonly in cell culture and microbiology laboratories to suspend cells, although it can be used to mix many other substances. It consists of an electric motor with the drive shaft oriented vertically and attached to a cupped rubber piece mounted slightly off-center. As the motor runs the rubber piece oscillates rapidly in a circular motion. When a test tube or other appropriate container is pressed into the rubber cup (or touched to its edge) the motion is transmitted to the liquid inside and a vo ...
