“…Among the 20 samples, 2 samples (10%) were resistant to Cefoxitin and 2 samples (10%) resistant to Oxacillin. The small number of samples found resistant to Cefoxitin and Oxacillin are consistent with the results observed by Pereira and Cunha (2009), where all the strains of S. aureus isolated from nursing students were susceptible to Oxacillin and Cefoxitin, suggesting that these bacteria are found in the community.…”

“…These data can be corroborated with the findings described by (Goldmann & Sands, 1992) who obtained an incidence rate of carriers of this microorganism between 30 to 40%, according to the author. Pereira and Cunha (2009) in their study of nasal colonization by Staphylococcus spp. resistant to Oxacillin in nursing students demonstrated a high rate of student carriers who had no prior contact to the hospital, which is consistent with the results obtained in this study, which observed 38% of positive samples for S. aureus in students from the first period, revealing that S. aureus is very present in the microbiota of people.…”

“…There are two mechanisms, which can result in the resistance to this antibiotic, firstly the macrolide flux controlled by msrA and the second is the modification of the binding site in the ribosome, controlled by the erm gene (Erythromycin Ribosomal Methylase).The ribosomal methylation is responsible for cross-resistance to Macrolides, Lincosamides and Streptogramins B, called MLSb phenotype in staphylococci ermA and ermC. These are genes related to the expression of this phenotype, making the modification in the binding target due to the methylation of residue A2058, locatedin the V domain of 23s (Naimi et al, 2001;Pereira & Cunha, 2009). S. aureus synthesizes ribosomal methylase, which is encoded by the erythromycin resistance gene or another methylases (ERM).…”

Staphylococcus aureus causes a large variety of infections, where many of them are acquired in the hospital environment. A significant part of the population is a nasal carrier of this type of microorganism. The present study evaluated the nasal colonization by S. aureus, identifying its resistance profile in nursing students from a private educational institute of higher education. Nasal swab samples were collected and identified for S. aureus. Moreover, an antibiogram assay was performed, followed by the search for ermA and ermC genes using PCR. Sixty-two students were included and we isolated 20 positive samples (32,5%) for S. aureus. For the phenotypic profile, 30% were found to be resistant to Erythromycin and 10% to Oxacillin and Cefoxitin. For the D-test in the genotypic profile, 25% presented mecA gene (MRSA), 5% of ermA gene, 35% of ermC gene and 10% with ermC and mecA genes. These data reinforce the necessity of monitoring bacterial colonization in hospital environment, which are potentially resistant in health professionals.

Introduction: Wounds can be colonized by methicillin-resistant Staphylococcus aureus (MRSA). Methods: We evaluated the prevalence of S. aureus and MRSA in the wounds of patients treated at Basic Health Units in Brazil and identifi ed risk factors associated with their presence. Results: The prevalence rates of S. aureus and MRSA were 51.5% and 8.7%, respectively. There was a correlation between the presence of S. aureus in wounds and nostrils (p<0.01). A positive association was detected between S. aureus infection and previous benzylpenicillin use (p=0.02). No associations were observed for MRSA. Conclusions: Multidrug-resistant pathogens are present in primary healthcare settings in Brazil.

The bacteria of the genus Staphylococcus present as Gram-positive cocci, grouped in clusters and are mainly found in normal human flora (skin and mucosa). They are classified by the ability to clot plasma coagulase positive or negative coagulase. The coagulase-negative Staphylococci (CNS) have become relevant in the clinic after the identification of these microorganisms in infections. The emergence of antimicrobialresistant strains in hospitals raises concerns regarding these microorganisms. This study aimed to evaluate the frequency of nasal colonization by CNS and its resistance profile methicillin professionals of a health institution in the region northern of the Espirito Santo. Samples were collected from the nasopharynx of volunteers, isolated Mannitol Salt Agar and identified by Gram staining technique, the catalase test and free coagulase. The methicillin resistance profile was evaluated by susceptibility of the organism against the oxacillin disk. Of the 38 samples collected, isolated in 31 (81.6%) the CNS. Of 30 samples CNS assayed for sensitivity to oxacillin, 23 (76.7%) showed resistance. It was found that professionals in direct contact with patients have more frequently resistant CNS. Therefore, it is considered important to the care of the spread of resistant strains of microorganisms by professionals in a hospital setting, avoiding causing major damage to the health of patients and higher expenses for health services.
