Evaluation of the modified broth-disk method for determining antibiotic susceptibilities of anaerobic bacteria.
A total of 110 strains of anaerobic bacteria including 9 different genera was tested for antibiotic susceptibility by the modified broth-disk method of Wilkins and Thiel (1973), using prereduced media and the VPI anaerobic culture system. Results were compared with those obtained with an agar dilution technique with incubation in a GasPak jar. There was greater than 95% agreement between the tw...
متن کاملAntibiotic susceptibilities of Helicobacter pylori.
OBJECTIVE The aim of this study was to evaluate the prevalence of resistance among 83 Helicobacter pylori isolates cultured from biopsies taken during routine endoscopies in 1998-1999. METHODS Minimum Inhibitory Concentration of amoxicillin, tetracycline, clarithromycin and metronidazole were determined by Epsilometer test. RESULTS Forty-seven strains (57%) were resistant to metronidazole, ...
متن کاملMechanisms that may account for differential antibiotic susceptibilities among Coxiella burnetii isolates.
The Nine Mile, S Q217, and Priscilla isolates, representative of the three major genetic groups of Coxiella burnetii, are known to differ in their susceptibilities to antibiotics. Mechanisms potentially responsible for these differences were investigated. Accumulation of antibiotics by infected L929 cells and purified isolates was measured. In addition, C. burnetii plasmid-transformed Escherich...
متن کاملNovel evolutionary pathways of sex-determining mechanisms.
Evolutionary transitions between sex-determining mechanisms (SDMs) are an enigma. Among vertebrates, individual sex (male or female) is primarily determined by either genes (genotypic sex determination, GSD) or embryonic incubation temperature (temperature-dependent sex determination, TSD), and these mechanisms have undergone repeated evolutionary transitions. Despite this evolutionary lability...
متن کاملStaphylococcal small colony variants have novel mechanisms for antibiotic resistance.
Over the past 4 years, a variant subpopulation of Staphylococcus aureus has been characterized that is defective in electron transport. These organisms grow slowly and are typical of the previously described small colony variants (SCVs). Indeed, many earlier papers included data that are consistent with defective respiratory activity in SCVs. We present a hypothesis that serves as biochemical b...
