Growth of staphylococci on mercuric chloride agar.
Smith, P. B. (Communicable Disease Center, Atlanta, Ga.). Growth of staphylococci on mercuric chloride agar. J. Bacteriol. 84:1016-1019. 1962.-An attempt has been made to corroborate a report that "epidemic" strains of staphylococci are more resistant to mercuric salts than are "nonepidemic" strains. A comparison of mercury resistance with coagulase production and phage type or pattern of 493 s...
متن کاملCo-trimoxazole sensitivity testing: comparison of separate and combined disk agar diffusion techniques.
Five hundred and seven strains of bacteria isolated from the urine of patients with significant bacteriuria (more than 10(8) colony-forming units per litre) were tested for sensitivity to co-trimoxazole by the agar diffusion technique. Each organism was tested with a combined disk containing trimethoprim and sulphamethoxazole in a primary sensitivity test and, at a standardised inoculum, with b...
متن کاملEnhancement of Colonial Growth of Brucellae on Beef Liver Agar.
Beef liver agar (Stafseth, Mich. State Univ. Agr. Expt. Sta. Tech. Bull. No. 49, part 2, 1920) inoculated with large numbers of brucellae is one of the most satisfactory media for obtaining rapid and abundant surface growth. Certain aerobic strains of this genus fail to grow on liver agar plates when the surfaces are inoculated with 103 or fewer live cells. Attempts (Polding, Med. Res. Council ...
متن کاملGrowth of Desulfovibrio on the surface of agar media.
Growth of Desulfovibrio desulfuricans (API strain) was found to take place in an atmosphere of hydrogen on the agar surface of complex media, including yeast extract (Difco), and Trypticase Soy Agar (BBL) without any added reducing agents. For growth on a 2% yeast extract-agar surface in the absence of hydrogen (nitrogen atmosphere), sodium lactate was required in the medium. Growth on the surf...
متن کاملDetection with Agar Dilution Susceptibility Testing
A dye reduction method for determining a definitive endpoint with agar dilution susceptibility testing has been developed. Bacterial growth was determined by applying to the inoculum spot a dye solution containing 2-(p-iodophenyl)-3-(pnitrophenyl)-5-phenyltetrazolium chloride and phenazine methosulfate. Viable colonies reduced the tetrazolium salt to a visible red color within 3 to 5 min. The m...
