Dynamic cell surface hydrophobicity of Lactobacillus strains with and without surface layer proteins.
Variations in surface hydrophobicity of six Lactobacillus strains with and without an S-layer upon changes in ionic strength are derived from contact angle measurements with low- and high-ionic-strength aqueous solutions. Cell surface hydrophobicity changed in response to changes in ionic strength in three out of the six strains, offering these strains a versatile mechanism to adhere to differe...
متن کاملThe effect of Lactobacillus reuteri cell free supernatant on growth and biofilm formation of Paenibacillus larvae
Background: Paenibacillus larvae is the etiological agent of American foulbrood (AFB) disease, the most lethal disease in honeybee (Apis mellifera) larvae. Aims: The aim of the present work was to study the antimicrobial effect of cell free supernatant (CFS) of probiotics on an Iranian isolate’s biofilm formation. Methods: A l...
متن کاملSerological Classification and Comparison of Cell Surface Hydrophobicity and Biofilm and Proteases Formation between the Clinical and Environmental Isolates of Pseudomonas Aeruoginosa
Background & Aims: Pseudomonas aeruoginosa is an opportunistic pathogen and an important cause of nosocomial infections. Different factors are involved in the pathogenicity of this bacterium. This study was performed to compare some factors associated with the virulence of clinical and environmental isolates of P. aeruoginosa. Methods: The present study was performed on 25 environmental isolate...
متن کاملCorrelation of Biofilm Formation and Caco-2 Cell Attachment Properties in Colonization Ability of Acid-Bile Resistant Fecal Lactobacillus plantarum Isolates
Introduction: The strain-specific capabilities of lactobacilli are critical for gut colonization. In this study, we evaluated various colonization determinants of 42 fecal Lactobacillus plantarum isolates from the healthy human fecal samples. Methods: We investigated the attachment to the Caco-2 cell line, biofilm formation ability and cell surface activity of the isolates. Such properties were...
متن کاملRelationship of cell surface hydrophobicity with biofilm formation and growth rate: A study on Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli
Objective(s): This study was designed to determine the relationship of Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli isolates in multispecies biofilms and their individual phenotypic characters in biofilm consortia. Materials and Methods: The subject isolates were recovered from different food samples and identified on the basis of growth on differential and selective med...
