Comparative Proteomic Analysis of Protein Patterns of in Biofilm and Planktonic Lifestyles.

is a clinically relevant bacterial pathogen, particularly in cystic fibrosis (CF) patients. Despite the well-known ability to form biofilms inherently resistant to antibiotics and host immunity, many aspects involved in biofilm formation are yet to be elucidated. In the present study, a proteomic approach was used to elucidate the differential protein expression patterns observed during the planktonic-to-biofilm transition of Sm126, a strong biofilm producer causing chronic infection in a CF patient, to identify determinants potentially associated with biofilm formation.

Subinhibitory concentrations of moxifloxacin decrease adhesion and biofilm formation of Stenotrophomonas maltophilia from cystic fibrosis.

Stenotrophomonas maltophilia is an emerging nosocomial bacterial pathogen that is currently isolated with increasing frequency from the airways of cystic fibrosis (CF) patients. In this study the effect of subinhibitory concentrations (subMICs) of moxifloxacin on adhesion, biofilm formation and cell-surface hydrophobicity of two strains of S. maltophilia isolated from CF patients were evaluated.

Factors associated with adherence to and biofilm formation on polystyrene by Stenotrophomonas maltophilia: the role of cell surface hydrophobicity and motility.

We tested 40 clinical Stenotrophomonas maltophilia strains to investigate the possible correlation between adherence to and formation of biofilm on polystyrene, and cell surface properties such as hydrophobicity and motility. Most of the strains were able to adhere and form biofilm, although striking differences were observed. Eleven (27.

Effect of environmental factors on biofilm formation by clinical Stenotrophomonas maltophilia isolates.

The influence of environmental factors (temperature, aerobiosis-anaerobiosis, static-dynamic conditions, pH) was determined on biofilm formation by 51 S. maltophilia clinical isolates. The strains produced more biofilm at 32 degrees C than at 37 or 18 degrees C.

Biofilm formation by the emerging fungal pathogen Trichosporon asahii: development, architecture, and antifungal resistance.

Trichosporon asahii is the most common cause of fatal disseminated trichosporonosis, frequently associated with indwelling medical devices. Despite the use of antifungal drugs to treat trichosporonosis, infection is often persistent and is associated with high mortality. This drove our interest in evaluating the capability of T.
