Synergism of plant compound with traditional antimicrobials against Streptococc...
Maia, Natasha L.; Barros, Mariana de; Oliveira, Leandro L. de; Cardoso, Silvia A.; Santos, Marcelo H. dos; Pieri, Fabio A.; Ramalho, Teodorico C.Mastitis is an inflammation of the mammary gland that causes major losses in the dairy industry. Streptococcus spp. are among the main agents of this disease. Increased resistance to antibiotics is one of the causes of therapeutic failure. Plants, due to their broad chemodiversity, are an interesting source of new molecules with antibacterial activity. Using these compounds along with traditional antibiotics is...
Quantificação de fatores de crescimento na pele de equinos tratada com plasma r...
Souza, Maria V. de; Pinto, José de O.; Costa, Marcela M. da; Santos, Eliziária C. dos; Garcia, Silvana L.R.; Oliveira, Leandro L. deO plasma rico em plaquetas (PRP) é um produto derivado da centrifugação do sangue total, sendo rico em fatores bioativos, como os de crescimento. Apesar da ampla utilização em processos cicatriciais, há controvérsia sobre a eficácia da terapia na cicatrização cutânea. O objetivo desse estudo foi quantificar e comparar a concentração dos fatores TGF-β1 e PDGF-BB no PRP, plasma sanguíneo e pele, durante diferente...
Production and Characterization of β-Glucanase Secreted by the Yeast Kluyveromy...
Lopes, Mariana R.; Souza, Carlos J. A. de; Rodrigues, Marina Q. R. B.; Costa, Daniela A.; Santos, Ancély F. dos; Oliveira, Leandro L. deAn extracellular β-glucanase secreted by Kluyveromyces marxianus was identified for the first time. The optimal conditions for the production of this enzyme were evaluated by response surface methodology. The optimal conditions to produce β-glucanase were a glucose concentration of 4 % (w/v), a pH of 5.5, and an incubation temperature of 35 °C. Response surface methodology was also used to determine the pH and ...
Effects of the oral administration of viable and heat-killed Streptococcus bovi...
Paiva, Aline D.; Fernandes, Kenner M.; Dias, Roberto S.; Rocha, Alípio S.; Oliveira, Leandro L. de; Neves, Clóvis A.; Paula, Sérgio O. deAntimicrobial peptides have been suggested as an alternative to classical antibiotics in livestock production and bacteriocin-producing bacteria could be added to animal feeds to deliver bacteriocins in the gastrointestinal (GI) tract of ruminant and monogastric animals. In this study, viable (V) and heat-killed (HK) Streptococcus bovis HC5 cells were orally administered to pre-sensitized mice in order to asses...
