Real-time quantification of Pseudomonas fluorescens cell removal from glass surfaces due to bacteriophage FS1 application
Description :
Aims: To study the efficacy of the lytic phage φS1 in eliminating Pseudomonas fluorescens in the early stage of biofilm formation, using an in situ and real time methodology for cell quantification.
Methods and Results: Cell adhesion and phage infection studies were carried out in a parallel plate f...

Description :
Persistent urinary tract infections (UTI) are often caused by E. coli adhered to urothelium. This type of cells is generally recognized as very tolerant to antibiotics which renders difficult the treatment of chronic UTI. This work investigates the use of lytic bacteriophages as alternative antimicr...

Description :
This communication focuses on the efficacy of a specific lytic
phage, phage Ф S1, as a control agent of Pseudomonas
fluorescens biofilms. The effect of phage infection temperature
and the host growth temperature were evaluated. The
results obtained showed that the phage infection process
was tempera...

Description :
The influence of host growth temperature, phase and media, together with the effect of infection temperature on bacteriophage
ФS1 infection of Pseudomonas fluorescens were examined. The rates of cell lysis and phage release were determined and showed that
the efficacy of phage infection was optimal ...

Description :
Background
Phage ϕIBB-PF7A is a T7-like bacteriophage capable of infecting several Pseudomonas fluorescens dairy isolates and is extremely efficient in lysing this bacterium even when growing in biofilms attached to surfaces. This work describes the complete genome sequence of this phage.

Description :
Low concentrations of antibiotics can inhibit microbial adherence to medical device surfaces. However, little
is known about the changes that occur in the physiology of bacteria within biofilms formed in the presence of
subinhibitory (sub-MIC) concentrations of antibiotics. In this study, the densit...

Description :
Pseudomonas fluorescens biofilms contribute to the spoilage of dairy industry products due to the proteolytic activity of some Pseudomonas fluorescens strains. The eradication of these biofilms is difficult using the traditional chemical biocides due to the low removal action of these agents. Additi...

Description :
The presence of biofilms in industrial settings is problematic as bacteria are responsible for several losses including product spoilage. Biofilms are difficult to eradicate and their removal and destruction has been for long attempted using chemical biocides. These agents usually yield very low bio...

This study investigated the phenotypic characteristics of monoculture P. fluorescens biofilms grown under turbulent and
laminar flow, using flow cells reactors with stainless steel substrata. The cellular physiology and the overall biofilm activity,
structure and composition were characterized, and ...
