1. [Detecção dos genes icaA, icaD e bap e produção de biofilme por Staphylococcus aureus e estafilococos não-aureus isolados de mastite clínica e subclínica bovina]
RESUMO Algumas espécies de Staphylococcus causam infecções crônicas intramamárias e podem levar à formação de biofilme. No presente estudo, levantou-se a hipótese de que as espécies de Staphylococcus isolados da mastite bovina são capazes de formar biofilme in vitro associado à presença dos genes icaA, icaD ou bap. Um total de 200 isolados de St

3. Staphylococcal slime layers and biofilm from different origins
RESUMO: O gênero Staphylococcus abrange algumas das bactérias patogênicas mais importantes tanto para humanos como para animais. Ele é responsável pela mastite bovina e otite canina, além de estar presente na microbiota de animais e como contaminante em alimentos. Sua patogênese está relacionada à formação de cápsula e biofilme, que contribuem p

4. INVESTIGATION OF BIOFILM FORMATION IN COAGULASE-NEGATIVE STAPHYLOCOCCI ISOLATED FROM PLATELET CONCENTRATE BAGS
Platelet Concentrates (PCs) are the blood components with the highest rate of bacterial contamination, and coagulase-negative staphylococci (CoNS) are the most frequently isolated contaminants. This study investigated the biofilm formation of 16 contaminated units out of 691 PCs tested by phenotypic and genotypic methods. Adhesion in Borosilicate Tube (ABT)

5. Detection of exopolysaccharide production and biofilm-related genes in Staphylococcus spp. isolated from a poultry processing plant
Staphylococcus spp. can survive in biofilms for long periods of time, and they can be transferred from one point to another and cause environmental contamination in food processing. The aim of this study was to detect Staphylococcus strains isolated from a poultry processing plant by the presence of adhesion genes and the phenotypic production of exopolysacc

6. Comparison of methods for the detection of biofilm formation by Staphylococcus aureus isolated from bovine subclinical mastitis
Biofilm formation is considered to be a selective advantage for Staphylococcus aureus mastitis isolates by facilitating bacterial persistence in the udder. It requires attachment to mammary epithelium, proliferation and accumulation of cells in multilayers. The objective of this study was to determine the sensitivity and specificity of three techniques for t

7. Effect of sub-minimum inhibitory concentrations of ciprofloxacin, amikacin and colistin on biofilm formation and virulence factors of Escherichia coli planktonic and biofilm forms isolated from human urine
The aim of this study was to determine the effect of subinhibitory concentrations (sub-MICs) of ciprofloxacin, amikacin and colistin on biofilm formation, motility, curli fimbriae formation by planktonic and biofilm cells of E. coli strains isolated from the urine of patients with various urinary system infections. Quantification of biofilm formation was car

8. Biofilm production by clinical Staphylococci strains from canine otitis
This study determined the species of 54 staphylococci isolates from canine otitis and their ability to produce biofilm through the Congo red agar method, confirmed by scanning electron microscopy. The most frequently identified species were S. intermedius and S. simulans. Results showed that 30% of the strains were biofilm producers.

9. Atividade in vitro de agentes antimicrobianos contra biofilmes de Staphylococcus ssp. de otite canina / In vitro activity of antimicrobial agents against Staphylococcus ssp. biofilms from canine otitis
Historicamente, as bactÃrias foram vistas como organismos que vivem isolados, no entanto, Ã claro, agora, que a grande maioria de bactÃrias existe em comunidades complexas, conhecidas como biofilmes. As bactÃrias em biofilmes se encontram aderidas a superfÃcies diversas, tanto abiÃticas como biÃticas (dente, osso, mucosa), compondo um ecossistema alta

10. A simple and efficient diffusion technique for assay of endo β-1,4-xylanase activity
Endo-β-1, 4-xylanases is thought to be of great significance for several industries namely paper, pharmaceuticals, food, feed etc. in addition to better utilization of lignocellulosic biomass. The present investigation was aimed to develop an easy, simple and efficient assay technique for endo-β-1, 4-xylanases secreted by the aerobic fungi. Under the propo

11. Evaluation of different detection methods of biofilm formation in the clinical isolates
BACKGROUND: Microorganisms growing in a biofilm are associated with chronic and recurrent human infections and are highly resistant to antimicrobial agents. There are various methods to detect biofilm production like Tissue Culture Plate (TCP), Tube method (TM), Congo Red Agar method (CRA), bioluminescent assay, piezoelectric sensors, and fluorescent microsc

12. Formação de biofilme de Staphylococcus epidermidis isolado de cateter venoso central através de métodos fenotípicos e genotípicos
Apesar de ser principalmente um colonizador da pele e mucosas, Staphylococcus epidermidis, juntamente com outros estafilococos coagulase negativos, tornou-se um importante patógeno oportunista, responsável por infecções nosocomiais associadas ao uso de dispositivos implantáveis. O fator mais importante na patogênese de infecções estafilocócicas asso
