Infectious factors are taken into consideration in pathophysiology of autism spectrum disorders (ASD). ASD patients often suffer from gastrointestinal disorders. The intestinal microbiota of autistic patients significantly differs from that in healthy individuals. The aim of the study was to compare the profile of toxins produced by C. perfringens strains isolated from feces of children with ASD,...
Clostridium difficile is an important healthcare-associated pathogen, responsible for a broad spectrum of diarrheal diseases. The aim of this prospective study was to determine the occurrence of C. difficile infection (CDI), to characterize cultured C. difficile strains and to investigate the association of fecal lactoferrin with CDI. Between January 2013 and June 2014, 148 stool samples were obtained...
Stools from autistic and healthy children were studied for fecal lactoferrin, Clostridium difficile toxins, Clostridium perfringens enterotoxin and cultured for Clostridium spp. Elevated level of FLA was demonstrated in 24.4% stools, all from boys (31.25%). No toxins were detected. Clostridium spp. was isolated with similar frequency from all samples. C. perfringens were isolated significantly often...
Clostridium difficile strains are known as etiological agents of pseudomembranous colitis (PMC), antibiotic-associated diarrhea (AAC) and colitis (AAC) and hospital-acquired infections. The aim of this study was to determine the frequency of C. difficile infection among patients in the emergency room and to compare isolated strains by phenotypic and genotypic characteristics. During a period of 11...
The prevalence of Clostridium difficile and its toxins (A and B) in HIV-positive children in Poland was investigated in a group of 18 children, aged 6 months to 8 1/2 years. Stool samples were tested using an antigen detection method for toxin A/B, cytotoxicity-neutralization and culture. In 3 cases (17%) C. difficile toxins were detected in both stool samples and strains recovered from culture. The...
One hundred and fifty-five stool specimens of patients suspected for Clostridium difficile -associated diarrhoea, colitis or pseudomembranous colitis (PMC) were investigated. All patients were pre-treated with antibiotics, suffered from watery diarrhoea and abdominal pain and were hospitalized in different hospital units. Units varied from departments of surgery, internal medicine, intensive care,...
