    • Características fenotípicas e genotípicas de amostras de Escherichia coli 0157 produtoras de toxina Shiga 

      Bastos, Flavia Correa [UNIFESP] (Universidade Federal de São Paulo (UNIFESP), 2006-01-01)
      Shiga toxin-producing O157:H7 Escherichia coli has been identified as an important cause of hemorrhagic colites and Hemolytic Uremic Syndrome in many countries. Some studies conducted in Brazil have shown the presence of ...

    • Escherichia coli produtora de toxina Shiga ( STEC): marcadores de Virulência e análise clonal 

      Vaz, Tânia Mara Ibelli [UNIFESP] (Universidade Federal de São Paulo (UNIFESP), 2006-12-31)
      Forty eigth Shiga toxin-producing Escherichia coli (STEC) strains, the majority from human origin, and thirty non-STEC strains carrying eae and belonging to the same serogroups of STEC strains, and isolated between 1976 ...

    • Evaluation of the Susceptibility profiles, genetic similarity and presence of qnr gene in Escherichia coli resistant to ciprofloxacin isolated in Brazilian hospitals 

      Pereira, Andrea dos Santos [UNIFESP]; Andrade, Soraya Sgambatti [UNIFESP]; Monteiro, Jussimara [UNIFESP]; Sader, Helio Silva [UNIFESP]; Pignatari, Antonio Carlos Campos [UNIFESP]; Gales, Ana Cristina [UNIFESP] (Brazilian Society of Infectious Diseases, 2007-02-01)
      Increasing quinolone resistance has been reported worldwide, mainly among clinical isolates of Escherichia coli. The objectives of this study were to determine the susceptibility profile, the genetic relatedness, and the ...

    • Genetic relatedness among clinical strains of Stenotrophomonas maltophilia in tertiary care hospital settings in São Paulo State, Brazil 

      Almeida, Margarete Teresa Gottardo; Rubio, Fernando Gongora [UNIFESP]; Garcia, Doroti Oliveira; Pavarino-Bertelli, Érika Cristina; Rossit, Andrea Regina Baptista; Bando, Silvia Yano; Silbert, Suzane [UNIFESP]; Goloni-Bertollo, Eny Maria; Soares, Márcia Maria Costa Nunes; Martinez, Marina Baquerizo (Sociedade Brasileira de Microbiologia, 2007-06-01)
      Stenotrophomonas maltophilia is a Gram-negative bacillus, which is becoming widely recognized as an important nosocomial pathogen. The main objective of this study was to evaluate the genetic relatedness, by random amplified ...

    • Improving typeability of multiple bacterial species using pulsed-field gel electrophoresis and thiourea 

      Silbert, S.; Boyken, L.; Hollis, R. J.; Pfaller, M. A. (Elsevier B.V., 2003-12-01)
      Although pulsed-field gel electrophoresis is considered the gold standard technique for molecular typing, typeability may not be excellent for some bacterial species because of DNA degradation. Previous reports suggest ...

    • The Influence of Genetic Stability on Aspergillus fumigatus Virulence and Azole Resistance 

      dos Reis, Thaila Fernanda; Silva, Lilian Pereira; de Castro, Patricia Alves; Almeida de Lima, Pollyne Borborema; do Carmo, Rafaela Andrade [UNIFESP]; Marini, Marjorie Mendes [UNIFESP]; da Silveira, Jose Franco [UNIFESP]; Ferreira, Beatriz Henriques; Rodrigues, Fernando; Malavazi, Iran; Goldman, Gustavo H. (Genetics Society America, 2018)
      Genetic stability is extremely important for the survival of every living organism, and a very complex set of genes has evolved to cope with DNA repair upon DNA damage. Here, we investigated the Aspergillus fumigatus AtmA ...

    • Oxacilin-resistant Coagulase-negative staphylococci (CoNS) bacteremia in a general hospital at São Paulo city, Brasil 

      d'Azevedo, Pedro Alves [UNIFESP]; Secchi, C.; Antunes, A.l.s.; Sales, T.; Silva, F.m. [UNIFESP]; Tranchesi, R.; Pignatari, Antonio Carlos Campos [UNIFESP] (Sociedade Brasileira de Microbiologia, 2008-12-01)
      In the last decades, coagulase-negative staphylococci (CoNS), especially Staphylococcus epidermidis have become an important cause of bloodstream infections. In addition, rates of methicillin-resistance among CoNS have ...
