We report on the first occurrence of high-level gentamicin resistance (MICs > or = 512 microg/ml) in seven clinical isolates of Streptococcus pasteurianus from Hong Kong. These seven isolates were confirmed to be the species S. pasteurianus on the basis of nucleotide sequencing of the superoxide dismutase (sodA) gene. Epidemiological data as well as the results of pulse-field gel electrophoresi...

Streptococcus gallolyticus subsp. pasteurianus is an under-recognized pathogen and zoonotic agent causing opportunistic infections in humans. Despite increasing recognition of this subspecies as a cause for human infectious diseases, limited information is known about its antibiotic resistance mechanism. In this study, we aim to identify the molecular mechanism underlying the high macrolide res...

Six acetic acid bacterial isolates, obtained during a study of the microbial diversity of spontaneous fermentations of Ghanaian cocoa beans, were subjected to a polyphasic taxonomic study. (GTG)(5)-PCR fingerprinting grouped the isolates together, but they could not be identified using this method. Phylogenetic analysis based on 16S rRNA gene sequences allocated the isolates to the genus Acetob...

Lipid biomarkers, such as the various bacteriohopanetetrol (BHT) isomers studied here, are useful tools in tracing bacterially mediated nitrogen and carbon cycle processes affecting greenhouse gas emissions, including anaerobic oxidation of ammonia. Three BHT occur commonly environment. By chromatography, BHT-34S elutes first; it is produced by numerous bacteria. The two later eluting more cons...

The microbiological and metabolic outcomes of good cocoa fermentation practices can be standardized influenced through the addition starter culture mixtures composed yeast bacterial strains. present study performed two spontaneous 10 culture-initiated (SCI) processes (CFPs) in Costa Rica with local Trinitario cocoa. strains Saccharomyces cerevisiae IMDO 050523, Hanseniaspora opuntiae 020003, Pi...
