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...
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...
BACKGROUND Approximately 30-40% of children <1 year of age are Clostridium difficile colonized, and may represent a reservoir for adult C. difficile infections (CDI). Risk factors for colonization with toxigenic versus non-toxigenic C. difficile strains and longitudinal acquisition dynamics in infants remain incompletely characterized. METHODS Predominantly healthy infants (≤2 years) were rec...
Chronic exposure to toxigenic molds in water-damaged buildings is an indoor environmental health problem to which escalating health and property insurance costs are raising a statewide concern in recent times. This paper reviews the structural and functional properties of mycotoxins produced by toxigenic molds and their interactive health implications with antifungal drugs. Fundamental bases of...
