The objective of this study was to select appropriate bacteriophages that survive in the gastrointestinal tract of neonatal poultry and utilize those bacteriophages to reduce intestinal colonization of Salmonella enteritidis phage type 13A (SE) in challenged birds. Broiler chicks served as an in vivo biological filter to preferentially select bacteriophages from our bacteriophage library capabl...

Several marine bacteriophages, a ciliate (Uronema sp.), and a flagellate (Pseudobodo sp.) were used to study comparatively the grazing and clearance rates of four marine bacteria. Bacteria were fluorescently labelled using rhodamine isothiocyanate. The results obtained indicate that bacteriophages and flagellates caused a significantly higher (P , 0.025) decrease in the number of marine bacteri...

Cross-resistance between bacteriophages and colicins was studied using collections of bacteriophage- and colicin-resistant mutants of Escherichia coli K-12. No new examples were found of highly specific one-to-one cross-resistance of the type suggestive of common receptors. However, several groups of mutants showed tolerance to colicins and resistance to bacteriophages. Mutants known to be very...

Chen, Peter K. (Georgetown University, Washington, D.C.), Ronald V. Citarella, Omar Salazar, and Rita R. Colwell. Properties of two marine bacteriophages. J. Bacteriol. 91:1136-1139. 1966.-Various properties have been determined for two bacteriophages, NCMB 384 and 385, and their host, NCMB 397, a Cytophaga sp., isolated from the marine environment. The purified bacteriophages have been subject...

UNLABELLED Bacteriophages are a major cause of bacterial mortality and impose strong selection on natural bacterial populations, yet their effects on the dynamics of conjugative plasmids have rarely been tested. We combined experimental evolution, mathematical modeling, and individual-based simulations to explain how the ecological and population genetics effects of bacteriophages upon bacteria...

BACKGROUND Bacteria inhabiting the human body have important roles in a number of physiological processes and are known to be shared amongst genetically-related individuals. Far less is known about viruses inhabiting the human body, but their ecology suggests they may be shared between close contacts. RESULTS Here, we report the ecology of viruses in the guts and mouths of a cohort and demons...

In connection with growing problem of antimicrobial resistance, the search for alternative treatments infection is popular topic nowadays. This article represents an overview published data on therapeutic use bacteriophages, specifically in urinary tract infections. The history phage therapy infectious diseases from beginning 20th century to present days presented. paper also discuss mechanism ...

Abstract Bacteriophages offer unique benefits for the specific control of Erwinia amylovora , causative agent fire blight in pome fruit. Unfortunately, majority described phages were tested efficacy vitro only. Data from infection assays using pear slices or detached blossoms is rare and field trials are barely reported. It remains to be studied if bacteriophages could open field. This review s...

The presence of Lactococcus bacteriophages in milk can partly or completely inhibit milk fermentation. To prevent the problems associated with the bacteriophages, the real-time PCR was developed in this study for direct detection from whey and milk of three main groups of Lactococcus bacteriophages, c2, 936, and P335. The optimization of DNA extraction protocol from complex matrices such as whe...
