Journal ArticleDOI
Characterization of CMY-2-type beta-lactamase-producing Escherichia coli isolated from chicken carcasses and human infection in a city of South Brazil.
Vanessa Lumi Koga,Renato Pariz Maluta,Wanderley Dias da Silveira,Renan Augusto Ribeiro,Mariangela Hungria,Eliana Carolina Vespero,Gerson Nakazato,Renata Katsuko Takayama Kobayashi +7 more
TL;DR: This study showed the prevalence of E. coli strains producing blaCMY-2 linked to ISEcp1 that were present in both chickens and humans in a restricted area and suggested the presence of a highly diverse strains that harbor pAmpC, indicating no clonal dissemination.
Journal ArticleDOI
Multifunctional alginate nanoparticles containing nitric oxide donor and silver nanoparticles for biomedical applications.
Alessandro L. Urzedo,Marcelly Chue Gonçalves,Mônica H. M. Nascimento,Christiane Bertachini Lombello,Gerson Nakazato,Amedea B. Seabra +5 more
TL;DR: To the best of knowledge, this is the first report to demonstrate the ability of alginate NPs releasing NO and AgNPs with potent antimicrobial activity.
Journal ArticleDOI
Chitosan chemically modified to deliver nitric oxide with high antibacterial activity.
Milena T. Pelegrino,Joana C. Pieretti,Gerson Nakazato,Marcelly Chue Gonçalves,José Carlos Moreira,Amedea B. Seabra +5 more
TL;DR: Together, CS backbone chemically modified with S-nitroso moieties have yielded a polymer capable of generating therapeutic NO concentrations with strong antibacterial effect.
Journal ArticleDOI
Virulence Genes and Antimicrobial Resistance in Escherichia coli from Cheese Made from Unpasteurized Milk in Brazil.
Anna Carolina Leonelli Pires de Campos,Juan J. Puño-Sarmiento,Leonardo Pinto Medeiros,Luís Eduardo de Souza Gazal,Renato Pariz Maluta,Armando Navarro,Renata Katsuko Takayama Kobayashi,Eder Paulo Fagan,Gerson Nakazato +8 more
TL;DR: The presence of Escherichia coli in raw milk cheese from different States in Brazil is investigated and one strain was resistant to three antimicrobials (tetracycline, ampicillin, and nalidixic acid), a potential risk for public health.
Journal ArticleDOI
Biogenic silver nanoparticles reduce adherence, infection, and proliferation of toxoplasma gondii RH strain in HeLa cells without inflammatory mediators induction.
Laís Fernanda Machado,Raquel Arruda Sanfelice,Larissa Rodrigues Bosqui,João Paulo Assolini,Sara Scandorieiro,Italmar Teodorico Navarro,Allan Henrique Depieri Cataneo,Pryscilla Fanini Wowk,Gerson Nakazato,Juliano Bordignon,Wander Rogério Pavanelli,Ivete Conchon-Costa,Idessania Nazareth Costa +12 more
TL;DR: The nanoparticles reduced the adherence, infection, and proliferation of ROS and NO, in addition to immunomodulating the IL-8, and proved relevant to introduce a promising therapeutic alternative to toxoplasmosis.
