Current methods to detect the colonization factor antigens (CFAs) associated with enterotoxigenic Escherichia coli (ETEC) strains are cumbersome, with some methods requiring antibodies that are not readily available. To achieve a gene-based method, we designed 2 multiplex polymerase chain reaction reactions to detect genes encoding the most common ETEC fimbrial colonization factors, including C...
To assess the prevalence, the antimicrobials resistance and to identify risk factors of nasopharyngeal colonization by Streptococcus pneumoniae in children with sickle cell disease (SCD) using prophylactic penicillin and immunized with 7-valent pneumococcal conjugate vaccine. A total of 424 swabs were collected from the nasopharynx in 216 children with SCD and 109 samples from the control group...
background: enterotoxigenic escherichia coli (etec) strains are the major causes of diarrheal disease in humans and animals. colonization factors and enterotoxins are the major virulence factors in etec pathogenesis. for the broad-spectrum protection against etec, one could focus on colonization factors and non-toxic heat labile as a vaccine candidate. methods: a fusion protein is composed of a...
BACKGROUND Denture stomatitis is a common fungal oral infection of multifactorial etiology. Denture-related factors such as denture's age, hygiene, night wearing and colonization by Candida albicans are known to predispose to denture stomatitis. The aim of this study was to evaluate these factors and their relationship with the occurrence of denture stomatitis in a Lebanese population. MATERI...
The nares represent an important bacterial reservoir for endogenous infections. This study aimed to assess the prevalence of nasal colonization by different important pathogens, the associated antimicrobial susceptibility and risk factors. We performed a prospective cohort study among 1878 nonhospitalized volunteers recruited from the general population in Germany. Participants provided nasal s...
UNLABELLED Pressure ulcers (PU) are a major reservoir of methicillin-resistant Staphylococcus aureus (MRSA) in hospitals. The objectives of this study were to estimate the prevalence of MRSA colonization in PU of hospitalized patients with Stage II or higher PU, to identify risk factors for colonization of these wounds, and to ascertain whether MRSA colonization of PU increases the risk of MRSA...
BACKGROUND Candida species is the third commonest cause of sepsis among neonates. Colonization by Candida is a predictor for candidemia among preterm neonates. OBJECTIVES To determine prevalence of early Candida colonization and early outcome among colonized preterm neonates admitted to Mulago hospital Special Care Unit. METHODS A prospective observational cohort was conducted between Decem...
