An immunochromatographic strip (ICS) test was developed for the detection of diphtheria toxin by using an equine polyclonal antibody as the capture antibody and colloidal gold-labeled monoclonal antibodies specific for fragment A of the diphtheria toxin molecule as the detection antibody. The ICS test has been fully optimized for the detection of toxin from… (More)
A total of 250 Corynebacterium diphtheriae isolates from clinical cases and carriers in Russia were assayed by PCR directed at the A subunit of the diphtheria toxin gene to distinguish toxigenic from nontoxigenic strains; 170 strains were positive as indicated by the presence of the 248-bp amplicon. The results of this PCR assay were in complete concordance… (More)
The purpose of the present work was to inform about the first case of meningitis associated to the bacteria Alcaligenes xylosoxidans in a patient with HIV/AIDS. The patient was a 46-year-old male, with the antecedent of have been diagnosed for HIV/ AIDS, who attended in the Hospital Universitario de Colima, Mexico, with fever, shock and meningismus. The… (More)
We used 199 Corynebacterium diphtheriae isolated from 1995 to 1997 in Russia to evaluate the ability of random amplified polymorphic DNA (RAPD) to identify the unique clonal group that emerged there in 1990. Our data show that RAPD can reliably, reproducibly, and rapidly screen a large number of strains to identify the epidemic clonal group.
Based on our own and current literature data, we analyzed the prebiotic properties of polysaccharides and extracts of seaweeds. The role of prebiotics, particularly polysaccharides, in the normalization of intestinal microflora is discussed; consideration is also given to the possibility of seaweed polysaccharide fermentation by colonic microflora and… (More)
Effectiveness of saline suspension of Corynebacterium pseudodiphtheriticum containing spray was assessed in a 30-days chamber experiment modeling the effects of hyperthermia and polluted air on humans. Spray was targeted at eliminating Staphylococcus aureus from the nasal cavity of human subjects. Three of four volunteers became S. aureus carriers in the… (More)
In this report, we present a draft sequence of Bacillus subtilis KATMIRA1933. Previous studies demonstrated probiotic properties of this strain partially attributed to production of an antibacterial compound, subtilosin. Comparative analysis of this strain's genome with that of a commercial probiotic strain, B. subtilis Natto, is presented.
This report describes the first draft genome sequence of a Corynebacterium pseudodiphtheriticum strain. The information on the genome organization and putative gene products will assist in better understanding of the molecular mechanisms involved in the beneficial probiotic effects of this bacterium.
This report describes a draft genome sequence of Lactobacillus crispatus 2029. The reads generated by the Ion Torrent PGM were assembled into contigs with a total size of 2.2 Mb. The data were annotated using the NCBI GenBank and RAST servers. A comparison with the reference strain revealed specific features of the genome.
Lactobacillus crispatus 2029 isolated upon investigation of vaginal lactobacilli of healthy women of reproductive age was selected as a probiotic candidate. The aim of the present study was elucidation of the role of L. crispatus 2029 in resistance of the female reproductive tract to genitourinary pathogens using cervicovaginal epithelial model.… (More)
