Antimicrobial Resistance and Virulence of Staphylococcus spp. in patients from ...

Staphylococcus spp. is one of the major infection-associated bacteria within health care, especially in intensive care units, and one of principal cause of complication in cancer patients. This study compared the antimicrobial susceptibility profile and frequency of resistance (mecA, blaZ, ermA and ermC) and virulence (icaA, icaD and hlg) genes in Staphylococcus spp. from patients of Oncology Hospital (OH) and ...

Seroprevalence and spatial distribution dynamics of Yersinia pestis antibodies ...

Introduction: In Brazil, the plague is established in several foci located mainly in the northeastern part of the country, where it alternates between active and quiescent periods. These foci in the State of Ceará have high epidemiological importance. In addition to other plague detection activities, plague areas can be monitored through serological surveys of dogs and cats (domestic carnivores), which, followi...

Prevalência de anticorpos contra Yersinia pestis em carnívoros domésticos nos f...

The prevalence of antibodies against Yersinia pestis in domestic carnivores (dogs and cats), in plague areas in the State of Ceará, was analyzed to establish the importance of monitoring these animals within the routine practice of the plague control program. Over the decade 1997-2006, 146,732 serum samples were examined (95,883 from dogs and 50,849 from cats), of which 2,629 (2,234 from dogs and 395 from cats)...

Contribuição para o diagnóstico de peste

Despite the clinical-epidemiological features of plague, numerous suspected cases in Brazilian outbreaks have been discarded because of negative results from the hemagglutination test for antibodies against the Yersinia pestis F1 antigen. The transcendence of plague justifies studying whether such results are due to unresponsiveness to F1, and whether other Y. pestis proteins might be recognized in suspect seru...

A simple PCR-based procedure for plaque diagnosis

Supernatant of boiled spleen saline-suspensions of Yersinia pestis experimentally infected animals were used as template for PCR amplification without DNA extraction. PCR sensitivity was enhanced by a second round of amplification (Nested). No amplification was observed from non-infected animals.; Triturados de baços de animais infectados experimentalmente com Y. pestis, suspensos em salina foram fervidos e os ...

Vigilância sorológica da peste no Brasil no período de 1983 a 1992

Plague caused by Yersinia pestis, has persisted in Brazil in several natural foci spread throughout rural areas in the States of Ceara, Paraiba, Pernambuco, Piaui, Rio Grande do Norte, Alagoas, Bahia, Minas Gerais and Rio de Janeiro. Nationwide surveillance of plague in Brazil based on serological testing started in 1983. We now present an update report of the examinations carried out in our laboratory from 198...

Composição plasmidial e fatores associados à virulência em cepas de Yersinia pe...

Pathogenic Yersinia pestis isolates were collected during a plague outbreak at the Paraiba State in 1986. The Y. pestis isolates were investigated for the presence of virulence-associated factors and plasmid content. All strains analysed were proficient in the expression of the VW and fraction 1 antigens, pigment adsorption and pesticin-fibronolysin-coagulase production. A similar plasmid profile composed by fo...

Isolamento da Yersinia pestis nos focos pestosos do Nordeste do Brasil no perío...

No período de 1966 a 1982 foram isoladas 861 cepas de Yersinia pestis sendo 471 originadas de material de roedores e outros pequenos mamíferos, 236 de lotes de pulgas, 2 de lotes de Ornithodorus e 152 de seres humanos dos focos pestosos do Nordeste do Brasil. Entre os roedores, a espécie que concorreu para o maior número de isolamentos foi o Zygodontomys lasiurus pixuna que, também, forneceu o maior número de l...
