“…The overall adhesion values for unimplanted materials shown in Tables 1 and 2 support the view that the Teflon polymers (FEP and PTFE) have the lowest affinity for bacteria amongst the materials examined. Ludwicka et al (1984) have also examined the ability of S. epidermidis to adhere to a number of materials used for medical purposes and found adhesion greatest to the most hydrophobic polymers, silicone being the most hydrophobic of those they examined. Similarly, Hogt et al (1983) considered the adhesion of coagulasenegative staphylococci to FEP to be mainly due to hydrophobic interactions, although the adhesion of encapsulated strains has not been found to correlate with hydrophobicity (Hogt, Dankaert & Feijen, 1985).…”

“…Este ensaio foi realizado em triplicata para cada bactéria e material testado. Foi considerado que maior ângulo de contato para um líquido polar, como água bidestilada e meio de cultura BHI, indica menor interação deste com a camada superficial, sugerindo maior hidrofobicidade da superfície testada; para um líquido mais apolar, como p-xileno, menor ângulo de contato indica maior interação e superfície menos hidrofóbica (22)(23) .…”

“…Estudos têm demonstrado que a hidrofobicidade da superfície bacteriana pode desempenhar um papel muito importante nos fenômenos de adesão celular (21,23,25,(29)(30)(31)(32)(33) , embora haja muita discrepância nos resultados relatados na literatura. De acordo com outro trabalho, na fase exponencial de crescimento as bactérias tendem a se tornar mais hidrofóbicas e formar grumos, aderindo umas às outras ou a superfícies presentes no meio de cultura (34) .…”

“…For most of the assays with rayon and cotton fibers with detergent, the radioactivity associated with cells adherent to the disk was not significantly above background, thus only data with cotton disks are presented. As shown in Table III 25.2% to 4.22% [DB]) when compared to untreated controls. Similar results were seen for both strains at a cell concentration of 107 organisms/ml (data not shown).…”

“…Bacterial cells collected from centrifugation of 1 ml bacterial suspension (OD of 1.0 at 650 nm) were resuspended in 24 p1 of digestion buffer (30% raffinose in 0.05 M Tris pH 7.5 with 0.145 M NaCl) containing 25 pg of lysostaphin (Sigma) and 1 pug of deoxyribonuclease (Worthington Biochemicals Co., Freehold, NJ). This concentration of raffinose was employed as a hypertonic medium to stabilize the protoplasts that formed during lysostaphin digestion (14).…”
