Nishida, S. (Kanazawa University, Kanazawa, Japan), and G. Nakagawara. Isolation of toxigenic strains of Clostridium novyi from soil. J. Bacteriol. 88:1636-1640. 1964.-The cultural conditions for toxin production by Clostridium novyi were investigated, and the optimal constituents of a proper medium were determined. A comparison of the value of this medium with other media in regard to toxin pr...

PURPOSE To investigate the genetic diversity of toxigenic Clostridium strains isolated from soil, water, meat and its associated polluted sites of Southern India. MATERIALS AND METHODS A total of 27 identified isolates of six different toxigenic clostridial species including C. bifermentans , C. botulinum , C. chauvoei , C. ramosum , C. tetani and C. novyi were isolated and characterized by c...

An account is given of two separate outbreaks of diphtheria amongst mentally subnormal patients and nursing staff. In a total hospital population of about 1000 the number of people involved as carriers or cases was 60 and there were five deaths. The 60 people comprised 56 patients, of whom four were involved in both outbreaks, and four nurses. The organisms isolated were C. diphtheriae mitis bu...

Toxigenic strains of Vibrio cholerae, although not endemic in New Zealand, are isolated occasionally from recent overseas travellers. Isolates should be confirmed biochemically and serologically and the presence of cholera toxin genes established by a reference laboratory, as non-toxigenic strains are found here in the summer months. Serotypes O1 and O139 are the causative agents of epidemic ch...

background shiga-toxigenic escherichia coli is an important human pathogen cause of diarrhea, hemorrhagic colitis, hemolytic uremic syndrome and thrombotic thrombocytopenic purpura in humans is a significant public health. objectives the aim of this study was to determine the molecular characteristics and antimicrobial resistance properties of shiga toxigenic escherichia coli (stec) strains wit...

background: clostridium difficile (c. difficile) infection is one of the most important diseases in healthcare facilities and community. ribotypes 027 and 078 are known as hyper-virulent strain of c. difficile in molecular study. pcr-ribotyping is a suitable method to interpret the relation of c. difficile isolated from food and hospital. objectives: in the present study, the clostridim diffici...

METHODS Phages isolated from environmental waters in Bangladesh were tested for their host specificity towards V. cholerae O1 and O139, and the ability to disperse V. cholerae biofilms formed in the laboratory. Representative phages were further characterized by electron microscopy and whole genome sequencing. Selected phages were then introduced in various combinations to biofilms of toxigenic...

37 INTRODUCTION Vibrio bacteria naturally occur in marine environments worldwide and are not the result of pollution. At least 12 species are human pathogens. Toxigenic Vibrio cholerae is probably the most well known specie worldwide, because it is endemic in regions with poor sanitation and inadequate treatment of sewage and drinking water. It can cause an acute epidemic infection known as cho...
