Plasmids in Clostridium botulinum type A and Clostridium sporogenes
A procedure to rapidly screen Clostridium botulinum type A and Clostridium sporogenes for plasmids was developed. Plasmid profiles of five C. botulinum type A strains and seven C. sporogenes strains were determined and a possible relationship of plasmids to toxin production was examined. The …

Reducing Clostridium Difficile
… to reduce the number of laboratory identified Clostridium Difficile Infections (CDI) events by 20% by December 2015. This CNL projects focuses on reducing CDI in an 8 unit bed specifically designated for medically ill geriatric patients above 70 years old residing in the West Texas region. A …

Nitrogen metabolism and butanol production by South African clostridium beijerinckii and clostridium saccharobutylicum strains
… industry. A collection of 19 solventogenic Clostridium beijerinckii and 11 Clostridium saccharobutylicum strains isolated from the National Chemical Products (NCP) ABE fermentation plant in Germiston, South Africa, were classed according to species by a quick species-specific colony PCR and …

Clostridium difficile and its toxins
An investigation of Clostridium difficile has shown : 1. that the organism is resistant to cresols and phenolq and may be grown from material grossly contaminated with other organisms by culture in media containing these substances; strains isolated before this method was evised are also resistant …

Genetic studies on Clostridium acetobutylicum
… of the cellulolytic properties of Clostridium acetobutylicum and the development of a genetic transfer system for this organism. The production of a carboxymethyl cellulose and a cellobiase by C acetobutylicum was demonstrated. In liquid medium the carboxymethyl cellulase was …

Fermentation studies on Clostridium acetabutylicum
… An investigation into solvent production by Clostridium acetobutylicum in clostridial basal medium (CBM) , reinforced clostridial medium (RCM) , Leung and Robson media was undertaken with the aim of developing a partially defined laboratory medium which produced solvent yields comparable to …

Untersuchungen zur Substratspezifität der ADP-Ribosyltransferasen Clostridium botulinum C2-Toxin und Clostridium perfringens Iota-Toxin
Clostridium perfringens Iota-Toxin und Clostridium botulinum C2-Toxin gehören zur Familie der binären Aktin-ADP-ribosylierenden Toxine. Die Toxine bestehen aus einer Enzymkomponente (ADP-Ribosyltransferase) und einer separaten Bindungs- und Translokationskomponente, die die Zellaufnahme vermittelt. …

Identification of Operons in clostridium difficile
Clostridium difficile (C. difficile), an anaerobic, spore-forming, Gram-positive bacterium, is a major nosocomial pathogen that causes severe, toxin-mediated diarrhea and pseudomembranous colitis. Previous studies of pathogenic bacteria, including C. difficile, have investigated the operon …

Hospital Acquired Clostridium Difficile Infection Prevention
<p> Abstract</p> <p>The aim of my CNL Internship Project is to decrease the incidence of healthcare acquired C diff infections at the acute care unit 1800 to zero for the next quarter. This will be accomplished by developing an action plan to address the issue by collecting data from audits and …

Hydrogenase of Clostridium acetobutylicum ATCC 824
C. acetobutylicum is an anaerobic bacterium that produces acetic and butyric acids, hydrogen gas, and carbon dioxide during the exponential phase of growth. When the culture pH is allowed to remain near 4.5, the metabolism switches to the production of the neutral compounds (solvents) - acetone, …

Studies on the regulation of nitrogen metabolism in clostridium acetobutylicum NCP 262 and clostridium beijerinckii NCIMB 8052
In order to produce Clostridium acetobutylicum strains with improved solventogenic capabilities through genetic manipulation, a thorough understanding of the mechanisms governing solvent production is required. Nitrogen metabolism has been shown to be important in the regulation of sporulation and …

Étude des riborégulateurs glycine chez Clostridium difficile
Clostridium difficile est une bactérie pathogène opportuniste causant chaque année des ravages dans les hôpitaux. Depuis quelques années, elle est devenue de plus en plus résistante aux antibiotiques et représente un coût financier grandissant pour le système de santé qui peine à la traiter. De …

Exploiting Bacteriophages to Tackle Clostridium difficile Infection
Clostridium difficile infection (CDI) currently affects around 20,000 people each year, in healthcare institutions and in the community, and will often follow disruption of the gut microbiome. Current treatment strategies call for the use of further antibiotics, of which there is a limited choice. …

Phenotypic and genotypic characterisation of Clostridium Difficile
Clostridium difficile is at present one of the most common nosocomial infections in the developed world. Hypervirulent strains (PCR ribotype 027) of C. difficile which produce enhanced levels of toxins have also been associated with other characteristics such as a greater rate of sporulation and …
