Autores: Sobhy,Nagat; Aly,Fatma; El Kader,Ola Abd; Ghazal,Abeer; Elbaradei,Amira.
BACKGROUND: Staphylococcus aureus has been recognized as an important pathogen associated with inpatients and community infections. Community-acquired methicillin-resistant S. aureus (CA-MRSA) infections commonly present as skin and soft-tissue infections (SSTIs). Treatment often includes incision and drainage with or without adjunctive antibiotics. OBJECTIVES: This study aimed to identify CA-MRSA infections both phenotypically and genotypically, to determine their spectrum of antibiotic resistance, and to establish the best scheme for molecular distinction between hospital-acquired MRSA (HA-MRSA) and CA-MRSA by staphylococcal cassette chromosome mec (SCCmec) typing and detection of Panton Valentine leukocidin (PVL). MATERIALS: 50 swabs, from skin and soft...

Methicillin-resistant Staphylococcus aureus (MRSA) commonly causes infection in hospitalized patients. Since its appearance in the 1960s, the SCCmec has evolved throughout the years into 5 different types (I-V), each bearing a different set of genes. Infection with MRSA SCCmec types I, II or III is almost exclusively restricted to hospitalised patients. However, recently, community acquired MRSA (CA-MRSA) infections have been reported with increasing frequency, usually caused by a type IV SCCmec MRSA in nosocomial settings. We studied the prevalence of SCCmec types in 50 nosocomial strains collected from 1995 to 1999. The SCCmec complex type and presence of Panton-Valentine leukocidin (PVL) were determined by PCR. Strains had been previously typed by PFGE...

Epidemiology of Staphylococcus aureus infections and nasal carriage at the Ibn Rochd University Hospital Center, Casablanca, Morocco
Provedor de dados: 55
Autores: Zriouil,Sanaâ Bouhali; Bekkali,Mohammed; Zerouali,Khalid.
Infections caused by Staphylococcus aureus are a major problem in hospitals. The multidrug resistance and the nasal carriage of S. aureus play a key role in the epidemic of these infections. In this prospective study, 160 S. aureus strains were isolated from pathological samples of patients (79 cases) and nasal swabs (81) of cases and controls from January to July 2007. The susceptibility to 16 antibiotics, including cefoxitin, was determined by the agar diffusion method, and methicillin resistance was confirmed by amplifying the mecA gene by polymerase chain reaction (PCR). The prevalence of methicilin-resistant S. aureus (MRSA) was high in the burns (57.7%) and dermatology (39.4%) wards, and the MRSA strains isolated were extremely multi-resistant, but...

Autores: Timerman,Artur; Brites,Carlos; Bicudo,Eliana; Grinbaum,Renato S.; Costa Filho,Rubens; Carrilho,Claudia D.M.; Bichels,Andre; Barreto,Tânia.
OBJECTIVES: To collect data about non-controlled prescribing use of daptomycin and its impact among Brazilian patients with serious Gram positive bacterial infection, as well as the efficacy and safety outcomes. MATERIALS AND METHODS: This is a multi-center, retrospective, non-interventional registry (August 01, 2009 to June 30, 2011) to collect data on 120 patients (44 patients in the first year and 76 patients in the second year) who had received at least one dose of commercial daptomycin in Brazil for the treatment of serious Gram-positive bacterial infection. RESULTS: Right-sided endocarditis (15.8%), complicated skin and soft tissue infections (cSSTI)wound (15.0%) and bacteremia-catheter-related (14.2%) were the most frequent primary infections; lung...

Prevalence of Staphylococcus aureus introduced into intensive care units of a University Hospital

Autores: Cavalcanti,Silvana M.M.; França,Emmanuel R. de; Cabral,Carlos; Vilela,Marinalda A.; Montenegro,Francisco; Menezes,Daniela; Medeiros,Ângela C.R.
Staphylococcus aureus is one of the principal human pathogens that colonize healthy individuals in the community in general, and it is responsible for severe infections in hospitalized patients. Due to an increase in the prevalence of strains of methicillin-resistant S. aureus (MRSA), combating these microorganisms has become increasingly difficult. A descriptive study was carried out on 231 patients in intensive care at the Oswaldo Cruz University Hospital (HUOC) in Recife, Brazil between January and April 2003 to determine the prevalence of S. aureus and MRSA and to evaluate risk factors for colonization by these bacteria when introduced into Intensive Care Units (ICUs). Body secretions were collected from the nostrils, axillary and perineal regions, and...

Provedor de dados: 58
Autores: Chah,Kennedy F.; Gómez-Sanz,Elena; Nwanta,John A.; Asadu,Brendan; Agbo,Ifeoma C.; Lozano,Carmen; Zarazaga,Myriam; Torres,Carmen.
The occurrence, resistance phenotype and molecular mechanisms of resistance of methicillin-resistant staphylococci from groin swabs of 109 clinically healthy dogs in Nsukka, Nigeria were investigated. The groin swab samples were cultured on mannitol salt agar supplemented with 10 µgof cloxacillin. Sixteen methicillin-resistant coagulase negative staphylococci (MRCoNS), all harbouring the mecA gene were isolated from 14 (12.8%) of the 109 dogs studied. The MRCoNS isolated were: S. sciuri subspecies rodentium, S. lentus, S. haemolyticus, and S. simulans with S. sciuri subspecies rodentium (62.5%) being the predominant species. Thirteen (81.3%) of the MRCoNS were resistant to tetracycline while 12 (75%) and 10 (62.5%) were resistant to kanamycin and...

Characterization of mannitol-fermenting methicillin-resistant staphylococci isolated from pigs in Nigeria
Provedor de dados: 58
Autores: Ugwu,Clifford C.; Gomez-Sanz,Elena; Agbo,Ifeoma C.; Torres,Carmen; Chah,Kennedy F.
This study was conducted to determine the species distribution, antimicrobial resistance pheno- and genotypes and virulence traits of mannitol-positive methicillin-resistant staphylococci (MRS) isolated from pigs in Nsukka agricultural zone, Nigeria. Twenty mannitol-positive methicillin-resistant coagulase-negative staphylococcal (MRCoNS) strains harboring the mecA gene were detected among the 64 Staphylococcus isolates from 291 pigs. A total of 4 species were identified among the MRCoNS isolates, namely, Staphylococcus sciuri (10 strains), Staphylococcus lentus (6 strains), Staphylococcus cohnii (3 strains) and Staphylococcus haemolyticus (one strain). All MRCoNS isolates were multidrug-resistant. In addition to β-lactams, the strains were resistant to...
