SUMMARY Over the last decade, Acinetobacter baumannii resistant to carbapenems has emerged in many medical centres and is commonly associated with high morbidity and mortality. We investigated potential mechanisms contributing to antimicrobial resistance of 58 clinical isolates of A. baumannii collected during a prolonged city-wide outbreak in five(More)
INTRODUCTION Bacterial colonization of the lungs is the main cause of morbidity in cystic fibrosis (CF). Pathogens such as Staphylococcus aureus are very well adapted to the pulmonary environment and may persist for years in the same patient. Genetic determinants of these bacteria, such as the presence of SCCmec have recently emerged as a problem in this(More)
INTRODUCTION Resistance to macrolides, lincosamides and streptogramins B (MLS(B) antibiotics) in staphylococci may be due to modification in ribosomal target methylase encoded by erm genes. The expression of MLS(B) resistance lead to three phenotypes, namely constitutive resistance (cMLS(B)), inducible resistance (iMLS(B)), and resistance only to macrolides(More)
Viruses are major contributors to acute respiratory infection-related morbidity and mortality worldwide. The influenza (IF) viruses and human respiratory syncytial virus (RSV) play a particularly important role in the etiology of acute respiratory infections. This study sought to standardize a one-step duplex real-time RT-PCR technique to optimize diagnosis(More)
Streptococcus agalactiae or group B Streptococcus (GBS) is one of the most important causal agents of serious neonatal infections. Numerous assays have been evaluated for GBS screening in order to validate a fast and efficient method. The aim of this study was to compare the culture technique (established as the gold standard) with the molecular method of(More)
Respiratory syncytial virus (RSV) is the main cause of lower respiratory tract illness in children worldwide. Molecular analyses show two distinct RSV groups (A and B) that comprise different genotypes. This variability contributes to the capacity of RSV to cause yearly outbreaks. These RSV genotypes circulate within the community and within hospital wards.(More)
Zebrafish is a powerful tool in pharmacological research and useful to identify new therapies. Probiotics can offer therapeutic options in alcoholic liver disease. This study was done in two independent experiments: first, we confirmed the intestinal colonization of probiotic Lactobacillus rhamnosus GG (LGG) after ethanol exposure. Second, four groups were(More)
