Pseudomonas fluorescens phages from sewage were tested against P. fluorescens isolates of soil and sewage. The phages were characterized as to host range, morphology, structural proteins and genome fingerprint. Of the seven phages isolated, one was found to be abundant in sewage (5.9×10(7) pfu/mL), having broad host range, and distinct protein and DNA profile when compared to the other six phag...

A series of bacteriophages, lytic for bacteria belonging to the genera Escherichia and Salmonella, were isolated. The phages were isolated from fecal samples, intestinal contents of turkey poults, and carrier cultures of S. typhimurium, S. typhimurium var copenhagen, S. heidelberg, and E. coli. The feasibility of using different habitats as sources of Salmonella phages was evaluated. The carrie...

• Global phage diversity is now primarily explored through cultivation-independent metagenomics. Metagenome-derived phages are typically linked to their host(s) via in silico predictions. Multiple alignment-dependent and alignment-free methods for host predictions have been proposed. Recent integrative approaches combining several into a single prediction seem most promising. Eventually, comple...

In this study we isolated novel bacteriophages, infecting the zoonotic bacterium Campylobacter jejuni. These phages may be used in phage therapy of C. jejuni colonized poultry to prevent spreading of the bacteria to meat products causing disease in humans. Many C. jejuni phages have been isolated using NCTC12662 as the indicator strain, which may have biased the selection of phages. A large gro...

Urinary tract infections (UTIs) caused by P. mirabilis are difficult to cure because of the increasing antimicrobial resistance of these bacteria. Phage therapy is proposed as an alternative infection treatment. The aim of this study was to isolate and differentiate uropathogenic P. mirabilis strain specific polyvalent bacteriophages producing polysaccharide depolymerases (PDs). 51 specific pha...

1. The presence of 0.25 M NaCl during the reaction between a staphylococcus phage and susceptible organisms results in a five to tenfold increase in the amount of phage produced. 2. Analysis of the reaction indicates that normal kinetic relationships exist until just before lysis occurs. At this time the organisms enter the stationary phase, lysis is delayed approximately 0.7 hour as compared w...

Phages targeting specific bacteria have been used for control of bacterial pathogens in plants and humans. We report results prophylactic use a natural cocktail phages on plants. Water was collected from upper reaches the Alaknanda river where more than 200 isolates reported. The water April 2020 before onset monsoons stored with sediments. sprayed twice weekly spinach, cabbage coriander did no...

1. Bacteriophage active against four species of bacteria was found in a salt solution extract of house flies. 2. A growth-inhibiting principle, not bacteriophage, active against four other species of bacteria was found to be present in the same extract. 3. An attempt to secure streptococcus bacteriophage by feeding to flies a streptococcus susceptible to the inhibitor but not to the bacteriopha...

The purpose of this study was to isolate and characterize Pseudomonas aeruginosa phages with regard to their morphology, growth characteristics, genetic material and structural protein composition. Five phages specific to P. aeruginosa PAO were isolated from sewage samples. Adsorption rates and one step growth curves of these phages were determined and on this basis, phages were found to be dis...
