Abstract:

Abstract A semiautomated microbiological folacin assay system is described. microcomputer A controls sample dilutions, medium addition, turbidity determination, and data acquisition. Assay capacity is 600 tubes per day, approximately twice that of comparable manual assays. Using the automated equipment, more samples can be compared within one assay, eliminating many sources of between-assay variation in large studies. Additional advantages of this sytem are reduced human errors, flexibility of assay design, and multifunctional component equipment. Folacin results from chicken liver, spinach, a

Abstract:

Abstract A simple, sensitive, and specific biodiffusion assay for the antibacterial ceftazidime was developed using a strain of Staphylococcus epidermidis (ATCC 12228) as the test organism. Ceftazidime was measured in powder for injection at concentrations ranging from 100 to 400 g/mL. The calibration graph for ceftazidime was linear (r2 = 1), and the method validation showed that it was precise (relative standard deviation = 0.415) and accurate. The results obtained by biodiffusion assay were statistically calculated by linear parallel model and by means of regression analysis and were verifi

Abstract:

Abstract Procedures for the assay of chloramphenicol in milk, urine, serum, and muscle tissue are presented. The procedures specify an assay design with all standards as well as samples present on each plate, oxytetracycline in the buffer-diluent for greater sensitivity, a minimal medium to enhance the inhibitory effect of chloramphenicol on the assay organism, and a tetrazolium dye to improve the ability to measure the zones of inhibition. Recoveries of unbound chloramphenicol from bovine urine were 90.8%, from serum 88.3%, from milk 79.3%, from swine muscle 71.3%, and from beef and chicken m

Abstract:

Abstract In a proposed method for determining oxytetracycline (OTC) in animal feed, OTC is extracted with acidic methanol, and the extract is centrifuged and assayed by microbiological plate assay and by reversed- phase liquid chromatography (LC). Riboflavin and furazolidone elute at retention times similar to that of OTC. Successful separations are made by using both dimethylformamide and acetonitrile mobile phases. Variation between microbiological and LC results is comparable with variation within the microbiological assay. The relative standard deviation for 6 replicates of feed at the 100

Abstract:

ABSTRACT Calcineurin inhibitors may augment the effects of antifungal drugs in microbiological assays. We examined this interaction in a microbiological assay for posaconazole. No effect was observed. However, concurrent or recently discontinued treatment with other antifungal drugs caused false-positive results, emphasizing a limitation of microbiological assays for antifungal drug level measurement.
