We evaluated the activity of ceftobiprole against 100 community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) and 100 hospital-associated MRSA (HA-MRSA) isolates. Eight isolates were evaluated by time-kill studies for kill rate and potential for synergy with tobramycin. Ceftobiprole MIC(50) and MIC(90) values were 1 and 2 microg/ml, respectively, against CA-MRSA and HA-MRSA. ...
BACKGROUND There are few studies in Brazil that address baseline prevalence of MRSA colonization and associated risk factors at hospital admission, or the incidence of nosocomial colonization. We report a prospective study in a tertiary-care, university-affiliated hospital to implement a new MRSA control policy at the institution. METHODS A cohort of randomly selected patients admitted to eme...
The distinction between healthcare-associated MRSA (HA-MRSA) and community-associated MRSA (CA-MRSA) infections has become increasingly blurred. We assessed the molecular characterization and antimicrobial resistance profile for MRSA isolates from blood. Most of all (81.9%) isolates are related to known HA-MRSA and CA-MRSA epidemic lineages, such as, USA300, USA400, USA600, USA800 and USA1100. ...
therapy without antibiotics. Finally, the hypothesis for MRSA being selected by the use of cefquinome in those horses cannot be excluded. In this study, two CCs with no geographical clustering were characterized. Indeed, three MRSA strains belonged to CC130, the most prevalent CC among mecC-positive MRSA in animals, whereas the fourth one belonged to ST49, which was recently described in mecC-p...
UNLABELLED ABSBACKGROUND: Since the detection of MRSA CC398 in pigs in 2004, it has emerged in livestock worldwide. MRSA CC398 has been found in people in contact with livestock and thus has become a public health issue. Data from a large-scale longitudinal study in two Danish and four Dutch pig herds were used to quantify MRSA CC398 transmission rates within pig herds and to identify factors a...
OBJECTIVES The emergence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has changed the epidemiology of MRSA infections worldwide. In contrast to hospital-associated MRSA (HA-MRSA), CA-MRSA more frequently affects healthy individuals, both with and without recent healthcare exposure. Despite obvious epidemiological differences, it is unknown whether differences in...
Staphylococcal cassette chromosome mec (SCCmec) types and Panton-Valentine leukocidin (PVL) gene carriage were compared among suspected community-associated methicillin-resistant Staphylococcus aureus MRSA (CA-MRSA) and health care-associated MRSA (HA-MRSA) isolates. CA-MRSA isolates carried the SCCmec type IV complex, and most were PVL positive. The HA-MRSA isolates carried the SCCmec type II ...
Staphylococcus aureus is an important pathogen that can cause a variety of infections, including superficial and systematic infections, in humans and animals. The persistent emergence of multidrug resistant S. aureus, particularly methicillin-resistant S. aureus, has caused dramatically economic burden and concerns in the public health due to limited options of treatment of MRSA infections. In ...
Background Antibiotic resistance in S. aureus is one of the major concerns and the rate of MRSA has dramatically increased in recent years. Clindamycin belongs to the MLS group and is used to treat skin and soft tissue infections. Resistance to clindamycin may be inducible (iMLSB) or constitutive (cMLSB) and it is present both in MRSA and MSSA. Treatment failure has been reported both in iMLSB ...
OBJECTIVES This study was designed to demonstrate the characteristics of qacA/B-positive Staphylococcus aureus in China. METHODS One hundred and forty-five MRSA and 178 MSSA from clinical specimens from seven hospitals in different regions of China, 70 MRSA from superficial sites of patients and 106 MRSA from environmental samples from an ICU were collected and screened for the presence of th...
