Coagulase-negative staphylococci (CoNS) are opportunistic pathogens that particularly cause infections in patients with implanted medical devices. The present research was performed to study the virulence potential of 53 clinical isolates of Staphylococcus capitis, Staphylococcus auricularis, Staphylococcus lugdunensis, Staphylococcus simulans, Staphylococcus cohnii and Staphylococcus caprae. A...
While it is generally accepted that most B lymphocytes express Fe-receptors (FcR) (1), 1 evidence for the expression of FcR by T cells is controversial. Thus, while some works have claimed that a high proportion of thymus cells display FcR (2), others have failed to demonstrate FcR on these cells (1). FcR, however, could be detected on several murine T cell lymphomas (2, 3, and footnote 2), and...
The diversity of clinical (n = 92) and oral and digestive commensal (n = 120) isolates of Streptococcus salivarius was analyzed by multilocus sequence typing (MLST). No clustering of clinical or commensal strains can be observed in the phylogenetic tree. Selected strains (92 clinical and 46 commensal strains) were then examined for their susceptibilities to tetracyclines, macrolides, lincosamid...
BACKGROUND Staphylococcus aureus, an important nosocomial pathogen, is frequently associated with infections in human. The management of the infections by it especially methicillin resistant ones is often difficult because methicillin resistant S. aureus is usually resistant to multiple antibiotics. Macrolide-lincosamide streptogramin B family of antibiotics is commonly used to treat such infec...
Résumé Introduction: Staphylocoque aureus reste un pathogène majeur de l'homme causant des infections très diverses, cutanées, urinaires, pulmonaires ainsi que des septicémies. L'objectif de ce travail est d'évaluer la sensibilité des souches communautaires de Staphylococcus aureus isolées dans différents produits pathologiques vis-à-vis des principaux antibiotiques utilisés, dans la région de ...
Aims: The aims of our study were to determine epidemiological markers of S. pyogenes isolates as well as the antimicrobial activities against these strains and we determined the macrolide and tetracycline resistance genes. Methodology and Results: We studied the epidemiological markers of 148 Streptococcus pyogenes isolates collected from children in Tunisia between October 2000 and December 20...
Sir, Haemophilus parasuis is the causative agent of Glässer’s disease, characterized by fibrinous polyserositis, polyarthritis and meningitis in pigs, which causes considerable economic losses in the swine industry. Macrolide antibiotics inhibit bacterial protein synthesis by binding to the 50S ribosomal subunit. Although macrolides are widely used in the treatment of Gram-positive infections, ...
We describe results from a multicenter study evaluating the Accelerate Pheno system, a first of its kind diagnostic system that rapidly identifies common bloodstream pathogens from positive blood cultures within 90 min and determines bacterial phenotypic antimicrobial susceptibility testing (AST) results within ∼7 h. A combination of fresh clinical and seeded blood cultures were tested, and res...
Clindamycin is one of the important alternative antibiotics in the therapy of Staphylococcus aureus infections. Clinical failure of clindamycin therapy has been reported due to multiple mechanisms that confer resistance to macrolides, lincosamides and Streptogramin B (MLSB) antibiotics. In vitro routine tests for clindamycin susceptibility may fail to detect inducible clindamycin resistance due...
Background and Objectives: Staphylococcus aureus is an important cause of nosocomial and community-acquired infections in every region of the world. Clindamycin is one of the alternative agents used to treat S. aureus infections and accurate identification of clindamycin resistance is important to prevent therapeutic failure. Unfortunately, inducible clindamycin resistance is ...
