[Micromethod of determining phosphatase activity of staphylococci]. 1996

V B Sboĭchakov, and I I Volkov, and V D Badikov

A rapid method for measuring phosphatase activity of staphylococci has been developed. Russian 96-well polystyrene plates are used. 0.1 ml of 0.2% sodium phenolphthalein phosphate solution in 1% peptone water, pH 6.8 to 7.0, and 0.1 ml of the tested strain suspension in normal saline are put into wells and incubated for 5 h at 37 degrees C. The results are assessed after adding 0.05 ml of 2.5% ammonia spirit into each well. If the result is positive, the medium is colored raspberry-red, if negative-light-yellow. The method is simple, available, and cheap.

D013210 Staphylococcus A genus of gram-positive, facultatively anaerobic, coccoid bacteria. Its organisms occur singly, in pairs, and in tetrads and characteristically divide in more than one plane to form irregular clusters. Natural populations of Staphylococcus are found on the skin and mucous membranes of warm-blooded animals. Some species are opportunistic pathogens of humans and animals.
D013211 Staphylococcus aureus Potentially pathogenic bacteria found in nasal membranes, skin, hair follicles, and perineum of warm-blooded animals. They may cause a wide range of infections and intoxications.
D013696 Temperature The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms. Temperatures
