| 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... |

| Methicillin-resistant Staphylococcus aureus is an established nosocomial pathogen (HA-MRSA, hospital acquired MRSA), but has recently begun to appear in the community (CA-MRSA, community acquired MRSA). The cause of resistance to methicillin and all other β-lactam antibiotics is the mecA gene, which is situated on a mobile genetic element, the Staphylococcal Cassette Chromosome mec (SCCmec). Seven major variants of SCCmec, type I to VII are distinguished. HA-MRSA disseminated worldwide and causes the majority of S. aureus nosocomial infections with a limited number of clones disseminated including the Brazilian Epidemic Clone (BEC, ST239-MRSA-III). CA-MRSA isolates are susceptible to non-β-lactam antibiotics, usually isolated from healthy individuals which... |

| It is known that Aeromonas spp. possess different chromosomal β-lactamase genes. Presence and phenotypic expression of blaTEM, blaSHV, and blaCTX-M ESBL-encoding genes were investigated in environmental water isolates of Aeromonas hydrophila and Aeromonas jandaei. Presence of blaSHV and blaCTX-M genes was not observed, and blaTEM gene was verified in 91% of the isolates. Sequencing of 10 fragments showed the occurrence of blaTEM-116. |

| Cinqüenta felinos hígidos, adultos - vinte e seis machos e vinte e quatro fêmeas - sem definição racial, com distintas idades, reunidos em dois grupos (GRUPO 1- animais domiciliados e GRUPO 2 - animais que rendados) de vinte e cinco animais cada. Após anamnese e prévia sedação, os gatos foram submetidos a exame físico e à otoscopia, comprovando-se a ausência de lesões meatais e timpânicas, com cureta de Buck e wragatoas estéreis, foi colhido material meatal, que foi então submetido a exames bacteriológico e micológico. No Grupo 1, foi evidenciado presença de Otodectes cynotis (4% das amostras), em 72% dos casos de bolores e leveduras (Cladosporium sp 66,6%, Malassezia sp 40%, Penicillium sp 33%, Aspergillus sp 33,3%, Rhodotorula sp 20,0%, Mycelia sp 13,3%... |
