Filamentous phages have distinguished roles in conferring many pathogenicity and survival related features to Gram-negative bacteria including the medically important Vibrio cholerae, which carries factors such as cholera toxin on phages. A novel filamentous phage, designated VFJΦ, was isolated in this study from an ampicillin and kanamycin-resistant O139(More)
Isoflavones were synthesized by two steps in good yields, starting from commercially available 2-hydroxyacetophenones and benzene analogs. First, intermediate 3-(dimethylamino)-1-(2-hydroxyphenyl) prop-2-en-1-ones were obtained by the condensation of 2-hydroxyacetophenones and DMF-DMA in DMF with high yields. Second, isoflavones were synthesized by(More)
OBJECTIVE To identify lactic acid bacteria (LAB) in commercial yogurts and investigate their antibiotic resistance. METHODS LABs were cultured from 5 yogurt brands and the isolates were identified at the species level by 16S rRNA sequence. Genotyping was performed by repetitive extragenic palindromic PCR (rep-PCR). The sensitivity to 7 antibiotics was(More)
