  Microbiological culture - Wikipedia, the free encyclopedia
A microbiological culture is a tool to determine the cause of infectious disease by letting the agent multiply (reproduce) in predetermined media in laboratory.
A Petri dish is often used to grow bacterial cultures.
The term culture can also, though infrequently and informally, be used as a synonym for tissue culture which involves the growth of cells or tissues explanted from a multi-cellular organism.

 Title 21 Code of Federal Regulations
A microbiological assay culture medium is a device that consists primarily of liquid or solid biological materials intended for medical purposes to cultivate selected test microorganisms in order to measure by microbiological procedures the concentration in a patient's serum of certain substances, such as amino acids, antimicrobial agents, and vitamins.
A supplement for culture media is a device, such as a vitamin or sugar mixture, that is added to a solid or liquid basal culture medium to produce a desired formulation and that is intended for medical purposes to enhance the growth of fastidious microorganisms (those having complex nutritional requirements).
A microbiological specimen collection and transport device is a specimen collecting chamber intended for medical purposes to preserve the viability or integrity of microorganisms in specimens during storage of specimens after their collection and during their transport from the collecting area to the laboratory.

 Pneumonia - Wikipedia, the free encyclopedia
The chest X-ray is the usual standard for diagnosis in hospitals or clinics with access to X-ray facilities; however, in a community setting (general practice), doctors typically decide whether to start antibiotics for mild cases of pneumonia on the basis of a history and physical examination alone.
Should a health provider have any specific concerns about the diagnosis, or should a patient fail to recover after a course of antibiotics, a culture of the patient's sputum is normally requested.
A blood sample may also be cultured to detect infection in the bloodstream (blood culture).

 Milk Sample Cultures   (Site not responding. Last check: 2007-11-07)
The infection status of mammary quarters is determined by microbiological culture of aseptically obtained milk samples and interpretation of the culture results.
Culture of milk samples generally results in one of three events: 1) no bacterial growth; 2) growth of a pure culture; or 3) growth of multiple colony types.
When a quarter milk sample results in the culture of three or more dissimilar colony types, the milk sample is most likely contaminated and the sample should be recorded as such.

 Method and apparatus for culturing with microbiological dry culture medium - Patent 5089413
A medium for culturing microorganisms can be prepared by dispersing gelling agent in an aqueous solution containing nutrients and other ingredients necessary for the growth of microorganisms.
Upon inoculation of the device with an aqueous sample suspected of containing microorganisms, the medium is reconstituted to form a homogeneous gel-like medium suitable for quantitative culturing of the microorganisms present in the sample.
In many microbiological tests, such as tests for bacteria identification or antibiotic susceptibility, broth media are used, and there is no need for a viscous gel.

 Culture Media
Microbiological culture media are used to detect and enumerate bacteria and other micro-organisms in clinical, food, and environmental samples.
Water supplies and the environment should be monitored for freedom from microbiological contamination that could cause serious problems such as typhoid and cholera.
The outstanding quality of dehydrated culture media from Biotec Laboratories serves as the perfect complement to the Company's strategic move into rapid microbiology, where its research into phage amplification has led to the development of revolutionary new assays for microbial detection.

Sensitivity and specifity of ATP bioluminescence compared with microbiological culture as a gold standard were calculated for all types of examined endoscopes together and displayed in a ROC curve for various threshold values.
Microbiological cultures of 15 endoscopes (5 bronchoscopes, 8 gastroscopes, 1 coloscope and 1 duodenoscope) were negative despite ATP bioluminescence above 100 RLU.
Compared with microbiological culture as a gold standard sensitivity of bioluminescence varied between 0.75 for a threshold of 30 RLU (95% confidence interval 0.55-0.89) and 0.46 for 100 RLU (95% confidence interval 0.28-0.66) and specifity between 0.43 (95% confidence interval 0.32-0.54) and 0.81 (95% confidence interval 0.71-0.89) respectively

 Microbiological diagnosis of prosthesis infections
Microbiological samples can be obtained by aspiration of the prosthetic joint or during operation.
However, multiple specimens for culture should be obtained from any suspected infection site, and the clinician should place the samples into transport media for anaerobic microorganisms.
The high likelihood of contamination precludes the routine use of microbiological culture for prosthesis-related infections without clinical signs or symptoms of infection, unless multiple specimens are taken.

Consistent microbiological diagnosis of infections and infectious diseases is not only the basis for well directed, individual treatment, but also for infection monitoring and statistics.
The quality and validity of the results of microbiological investigations are markedly influenced by the type and time of collection, storage factors, transport of the material to be tested, and by the communication of the patient’s essential data.
Take the blood culture flask straight to the laboratory; if this is not possible store in an incubator at 37 °C; use a thermoflask for transport outside the hospital or general practice.

Oxoid has launched its water plate count agar, a medium to permit the enumeration of culturable micro-organisms from water using a colony count technique
In addition, Oxoid Water PCA may be used to assess the suitability of a water supply for the preparation of food or drink, in order to avoid contaminating the product with harmful or spoilage micro-organisms.
Whatever the application, the detection of higher than expected levels of culturable micro-organisms in the water (based on frequent, long term monitoring) can provide an early warning of serious pollution and calls for immediate further investigation, as outlined in ISO 6222:1999 (E) Water Quality.

Up to now no specific legislation on water's microbiological characteristics in basins used for aquaculture is available; therefore, it is very important to monitor their hygienic and sanitary quality.
Aim of the present study was to estimate the level of hygiene and sanitation on the brackish water basin of Acquatina used for extensive and semi-intensive fish-culture.
The highest level of total coliforms and faecal coliforms were observed in the channels (Cardone {636 TC 100 mL^-1, 305 FC 100 mL^-1 and Giammatteo 267 TC 100 mL^-1 229 FC 100 mL^-1) while the concentration of contaminants of faecal origin in the basin was quite low during the whole year studied.
