Clostridium difficile and Clostridium perfringens type A are infectious agents of enteric diseases. The main virulence factors of these microorganisms include toxins A and B of C. difficile (ToxA and ToxB) and enterotoxin of C. perfringens (Cpe). In this study genetic constructions have been created for the expression of ToxA, ToxB and Cpe fragments either as individual components or as a hybri...
Clostridium difficile (C. difficile) is an important factor in the development of the gastrointestinal diseases because of irrational antibiotic prescription and antimicrobial resistance. In the past, this bacterium was introduced as an agent of the infection in the hospitals called "hospital acquired Clostridium difficile infection". This infection is a main cause of morbidity and mortality in...
Background: CClostridium difficile is an anaerobic gram-positive bacterium currently recognized as the most common cause of nosocomial infectious diarrhea in the nursing home. The antibiotic susceptibility profiles are the basic step to successful treatment due to the antimicrobial resistance. This present study assessed the susceptibility profiles of C. difficile, previously isolated from Elde...
Clostridium difficile (C. difficile) infection (CDI) is the main cause of nosocomial antibiotic-associated colitis and increased incidence of community-associated diarrhea in industrialized countries. At present, the primary treatment of CDI is antibiotic administration, which is effective but often associated with recurrence, especially in the elderly. Pathogenic strains produce enterotoxin, t...
Background and Aims: Clostridium difficile is an identified cause of antibiotic-associated diarrhea, antibiotic-associated colitis, pseudomembranous colitis and nosocomial diarrhea. The objective of this survey was to determine molecular analysis of toxigenic Clostridium difficile isolates from hospital environment in Tehran tertiary medical centers. Materials and Methods: In this descriptiv...
conclusions metronidazole and vancomycin still seem to be most effective drugs for treatment cdi. objectives the aim of this study was to investigate the antimicrobial susceptibility patterns of c. difficile clinical isolates against antibiotics commonly used for treatment cdi in hospitalized patients. material and methods during a 12 month study, 75 c. difficile isolates were collected from 39...
Clostridium difficilewas first isolated in 1935 in the normal flora of newborns.1 Since 1978, it has been reported to be a cause of antimicrobial-associated diarrhea, colitis, and pseudomembranous colitis.2 During the late 1970s and early 1980s, several studies concluded that two toxins, toxin A (enterotoxin) and toxin B (cytotoxin), were responsible for the characteristic symptoms of C. diffic...
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...
Clostridia difficile is a gram positive, spore forming anaerobic bacilli1 Infection occurs when the organism is ingested. Though initially thought of as a nosocomial infection, community acquired clostridia difficile infection is increasingly recognized.2 Clostridia Difficile produces a variety of toxins, toxin A (enterotoxin) and B (cytotoxin) are the toxins most frequently linked to disease. ...
Background: Staphylococcal superantigens (SAg;aposs) may have some role in otitis media with effusion (OME). The aim of this study was the search of staphylococcal SAg;aposs in middle ear effusion of children with OME. Methods: This cross sectional-analytic study was done in ENT & pediatric wards upon 64 children with otitis media with effusion (OME) between 1-15 years, (mean age=7.42+4 years)...
