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:

Amoxicillin is a moderate-spectrum antibiotic active against a wide range of Gram-positive, and a limited range of Gram-negative organisms. 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 - ...

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 ...

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 ...

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 ...

Nutrient agar is used throughout the world as a medium for the growth of bacteria and fungi, but not viruses. Though less than 1% of all existing bacteria can be grown successfully, the basic agar formula can be used to grow most of the microbes, whose needs are known. More specific nutrient agars are available, because microbes can be picky. For example, blood agar, which is generally combined with horse blood, can be used to detect the presence of haemorrhagic micro-organisms such as E.coli O:157 H:7. The bacteria digest the blood, turning the plate clear. Agarose ...

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 ...

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 ...

A virus is a microscopic parasite that infects cells in biological organisms. Viruses are obligate intracellular parasites; they can reproduce only by invading and controlling other cells as they lack the cellular machinery for self-reproduction. The term virus usually refers to those particles that infect eukaryotes (multi-celled organisms and many single-celled organisms), while the term bacteriophage or phage is used to describe those infecting prokaryotes (bacteria and bacteria-like organisms lacking a nucleus ...

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 ...

Microorganisms are found everywhere in nature. Even in hostile environments, like the poles, deserts, geysers, rocks, and the deep sea, some types of microorganisms have adapted to the extreme conditions and sustained colonies; these organisms are known as extremophiles. Some extremophiles have been known to survive for a prolonged time in a vacuum, and some can be unusually resistant to radiation. Microorganisms are used in brewing, baking, biotechnology, recycling of other organisms' remains and waste products, and many other processes. They can also be harmful a ...

Because viruses are acellular and do not have their own metabolism, they must utilize the machinery and metabolism of the host for the purpose of self-replication. Before a virus has entered a host cell, it is called a virion — a package of viral genetic material. Virions can be passed from host to host either through direct contact or through a vector, or carrier. Inside the organism, the virus can enter a cell in various ways. Bacteriophages—bacterial viruses—attach to the cell wall surface in specific places. Once attached, e ...
