| In the present study, we determined the frequency of superficial and cutaneous mycoses and their etiologic agents during a 7-year period (2002-2008) in Natal, Brazil. A total of 1,717 specimens of skin, nail, and hair were collected from 1,382 patients with suspected mycoses lesions and were then subjected to direct microscopy and culture. |

| Many methods have been described for the detection of methicillin-resistant Staphylococcus aureus (MRSA), but the heterogeneous expression of methicillin resistance affects the reliability of these methods. The aim of the present study was to evaluate some methods for detecting methicillin resistance in Staphylococcus aureus isolates in a university hospital located in the Northeast of Brazil. Among the isolates, 15 were methicillin-susceptible and 45 were methicillin-resistant, including low-level heterogeneous resistance strains. Both the 30 µg-cefoxitin disk and PBP2a test had 100% sensibility/specificity and appear to be good options for the detection of MRSA in the clinical laboratory. |

| The aim of this study was evaluate the in vitro antifungal activity of crude extracts from Eugenia uniflora, Libidibia ferrea and Psidium guajava. The extracts were obtained by turbo-extraction using water (AQ) or acetone-water (AC-W) (7:3, v/v) as solvents and lyophilized to obtain the crude extracts (CE). The CE were characterized by UV-Vis, TLC and HPLC. The activity of CEs was investigated against clinical isolates of Candida spp. and the Minimum Inhibitory Concentration (MIC), MIC50 and MIC90 were determinated. The analysis by TLC showed that all CEs presented polyphenols (flavonoids and tannins). The CEs from E. uniflora showed higher amount of polyphenols (30.35 ± 2.15%, AC-W) and the HPLC analysis revealed the tannins in all extracts. The CEs of E.... |

| All the newborns with umbilical venous catheters, hospitalized in the neonatal intensive care unit at Januário Cicco Maternity Hospital in Natal, Brazil, between January, 2003 and December, 2004 were studied. The prevalence of Candida species in the tips of intra-venous catheters was assessed, as well as the coexisting exposures that the patients were subjected to. Catheter tips were cultivated in blood agar and when yeast culture occurred, the colony was subcultivated for species identification through morphologic and biochemical assays. From a total of 240 catheters, 41 were positive for yeasts, and 34 were submitted to identification. The following agents were isolated: 13 C. albicans (38%), 10 Candida parapsilosis (29%), 8 C. tropicalis (20%), one C.... |
