Nakamura, Hakobu (Konan University, Kobe, Japan). Acriflavine-binding capacity of Escherichia coli in relation to acriflavine sensitivity and metabolic activity. J. Bacteriol. 92:1447-1452. 1966.-Inheritance of the acriflavine resistance gene by an acriflavine-sensitive strain of Escherichia coli K-12 resulted in a reduction in the cellular accumulation of acriflavine and other basic dyes, but ...

acriflavine (3,6-diaminoacridine) is an anticeptic drug developed in 1912. previous research has focused on investigation of the intercalating features of acriflavine, but little is known about its interaction with proteins. drug-receptor interaction is of major interest in clinical science. the aim of the present study was to evaluate the ability of acriflavine to induce alterations in conform...

AIMS To investigate the use of mannitol salt agar (MSA) supplemented with acriflavine for selective growth and quantification of Staphylococcus aureus from flushed dairy manure wastewater (FDMW). METHODS AND RESULTS Minimal inhibitory concentrations of acriflavine in MSA were determined by comparing the growth of S. aureus subsp. aureus (ATCC 33591) and Staphylococcus epidermidis (ATCC 155) i...

A pleomorphic dyskinetoplastic strain of Trypanosoma brucei was produced by repeated acriflavine treatment. No kinetoplastic cells reappeared after 2 yr of maintenance in the absence of acriflavine. These dyskinetoplastic cells retained and therefore replicated the central element of the kinetoplast. This element was present in the "condensed" state typical of acriflavine-treated cells rather t...

Eight hundred Erysipelothrix strains isolated between 1992 and 2002 from swine with erysipelas in Japan were serotyped. Thirty-seven, 47, 73, and 643 strains were isolated from animals with acute septicemia, urticaria, chronic endocarditis, and chronic arthritis, respectively, of which 381, 146, 254, and 19 isolates belonged to serotypes 1a, 1b, and 2b and other serotypes, respectively. All ser...

Dyskinetoplastic cells from both Crithidia fasciculata and Trypanosoma equiperdum lack detectable kinetoplast DNA (kDNA) by conventional staining techniques. Two dyskinetoplastic strains of T. equiperdum, either acriflavine-induced or spontaneously occurring, show normal amounts of kDNA (p = 1.692 g/cm3) in analytical caesium chloride, ultracentrifugation. Electron and fluorescence microscopy o...

Epithelial-to-mesenchymal transition (EMT) is linked to tumor invasion, drug resistance and aggressive disease and this is largely dependent on the cell's microenvironment. Acriflavine (ACF) is an old antibacterial drug recently also suggested as anticancer agent and HIF inhibitor. We wanted to study the effect of acriflavine on EMT in different human cancer models. Pancreatic cancer cells (Pan...

The effects of acriflavine on the fine structure and function of the mitochondria and the kinetoplast in Crithidia fasciculata have been investigated. A mitochondrial fraction was prepared by differential centrifugation of cells broken by grinding with neutral alumina. Isolated mitochondria or intact cells revealed by spectrophotometric measurements the presence of cytochromes a + a(3), b, c(55...

Gene vmrA, cloned from Vibrio parahaemolyticus, made Escherichia coli resistant to 4',6-diamino-2-phenylindol, tetraphenylphosphonium chloride, acriflavine, and ethidium bromide. VmrA belongs to the DinF branch of MATE family efflux transporters. VmrA catalyzed acriflavine efflux and showed Na(+)/drug transporter activity because the addition of tetraphenylphosphonium to Na(+)-loaded cells caus...
