Koch's four postulates are: [5] The microorganism must be found in abundance in all organisms suffering from the disease but should not be found in healthy organisms. The microorganism must be isolated from a diseased organism and grown in pure culture. The cultured microorganism should cause disease when introduced into a healthy organism.
The Florida Comprehensive Assessment Test, or the FCAT/FCAT 2.0, was the standardized test used in the primary and secondary public schools of Florida. First administered statewide in 1998, [1] it replaced the State Student Assessment Test (SSAT) and the High School Competency Test (HSCT). As of the 2014-2015 school year FCAT was replaced in ...
The curriculum of most public schools in the State of Florida and the FCAT are based upon this state system. [2] Development of the Sunshine State Standards began in 1993, and they were adopted by the Florida Board of Education in May 1996. The Next Generation Sunshine State Standards were approved between 2007 and 2010.
Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) 'life' and -λογία 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).
In microbiology, the minimum inhibitory concentration (MIC) is the lowest concentration of a chemical, usually a drug, which prevents visible in vitro growth of bacteria or fungi. [1] [2] MIC testing is performed in both diagnostic [1] [2] and drug discovery laboratories. [3] [4]
A 0.5 McFarland standard is prepared by mixing 0.05 mL of 1.175% barium chloride dihydrate (BaCl 2 •2H 2 O), with 9.95 mL of 1% sulfuric acid (H 2 SO 4). [ 1 ] Now there are McFarland standards prepared from suspensions of latex particles, which lengthens the shelf life and stability of the suspensions.
Once a bacterium has been identified following microbiological culture, antibiotics are selected for susceptibility testing. [5] Susceptibility testing methods are based on exposing bacteria to antibiotics and observing the effect on the growth of the bacteria (phenotypic testing), or identifying specific genetic markers (genetic testing).
