Both this media share some characeristics.MH it is a vuniversal media used routinlly in bacteriological labs to test antibiotic resistence.
Better diffusion of antibiotics is just one reason why MHA is used for antibiotic sensitivity test (ABST). There are several factors that affect the ABST, they are: Disc concentration, diffusability of the drug, nature and composition of the medium, thickness of the medium, pH of the medium, potency of the disc. The pH should be between 7.2 and 7.4. If the pH is too low, certain drugs loose potency (eg. aminoglycosides, quinolones and macrolides) while certain others show excess activity (eg. tetracycline). If the pH is too high then reverse reactions would occur. Excess moisture too affects the reliability of the result. Increased thymidine reverses the inhibitory effect of sulphonamides, MHA has decreased thymidine content. Increased con. of Mg 2+ and Ca 2+ affects the results of aminoglycosides and tetracycline, also reduces zone size in case of P. aeruginosa. Decreased cation increases the zone size. Increased Zn would decrease the zone size of carbapenen group of antibiotics. Some fastedious organisms like Haemophilus sp, N.gonorrheae, S. pneumoniae, S. viridans and beta hemolytic Streptococcusrequire MHA supplemented with 15micro gram per ml NAD, bovine hematin and yeast extract.
A scintillation counter measures ionizing radiation. The sensor, called a scintillator, consists of a transparent crystal, usually phosphor, plastic (usually containing anthracene), or organic liquid (see liquid scintillation counting) that fluoresces when struck by ionizing radiation. A sensitive photomultiplier tube (PMT) measures the light from the crystal. The PMT is attached to an electronic amplifier and other electronic equipment to count and possibly quantify the amplitude of the signals produced by the photomultiplier.
