Undergraduate students from a range of majors take part in biotechnology course to isolate and study bacteriophages, viruses that destroy bacteria cells by infecting them reproducing inside them. Some bacteriophages may be able help treat antibiotic-resistant bacteria. Students the class recently named one their for President Mitch Daniels.
background in recent decades bacteriophages have been used as treating agents against some pathogens. also, bacteriophages could be considered as alternatives of antimicrobial agents in plant protection. objectives this study aimed to isolate a pathogen from potato (solanum tubersom) tubers (pseudomonas putida), and of its specific bacteriophage from soil and wastewater. materials and methods i...
Bacteriophages active against specific Bacteroides host strains were shown to be suitable for detection of human faecal pollution. However, the practical application of this finding is limited because some specific host strains were restricted to certain geographic regions. In this study, novel Bacteroides host strains were isolated that discriminate human and animal faecal pollution in Switzer...
Background: Nowadays, due to the emergence of drug resistance to antibiotics, a good alternative to drugs should be found. Bacteriophages are viruses that play a very important role in the destruction of bacteria. Because of their specific properties, bacteriophages can be considered as suitable substitutes for antibiotics in the treatment of infectious diseases. The aim of this study was to is...
The Formosan subterranean termite; Coptotermes formosanus is nutritionally dependent on the complex and diverse community of bacteria and protozoa in their gut. Although, there have been many studies to decipher the taxonomic and functional diversity of bacterial communities in the guts of termites, their bacteriophages remain unstudied. We sequenced the metavirome of the guts of Formosan subte...
conclusions the overall results indicated that bacteriophages isolated from sewage exhibited excellent lytic activity against mrsa strains. in conclusion, bacteriophages can be further characterized and appear to be a promising candidate for phage therapy against mrsa in the future. results the phages exhibited good lytic activity against mrsa when tested in-vitro, and the highest activity was ...
The role of bacteriophages in influencing the structure and function of the healthy human gut microbiome is unknown. With few exceptions, previous studies have found a high level of heterogeneity in bacteriophages from healthy individuals. To better estimate and identify the shared phageome of humans, we analyzed a deep DNA sequence dataset of active bacteriophages and available metagenomic dat...
Bacteriophages (phages) are widely distributed in the biosphere and play a key role in modulating microbial ecology in the soil, ocean, and humans. Although the role of DNA bacteriophages is well described, the biology of RNA bacteriophages is poorly understood. More than 1900 phage genomes are currently deposited in NCBI, but only 6 dsRNA bacteriophages and 12 ssRNA bacteriophages genome seque...
Objective(s): During the last years with increasing resistant bacteria to the most antibiotics bacteriophages are suggested as appropriate treatment option. To investigate lytic activity of bacteriophages there are indirect microbial procedures and direct methods. The present study to complement microbial procedures and investigate ultra-structural characteristics of infection bacterium-phage u...
Relevance. Bacteriophage preparations are a promising tool for the prevention and treatment of zoonoses. The effectiveness use phage at different stages food production has been proven: in cultivation animals, processing their slaughter products sanitation finished from causative agent salmonellosis. creation an effective capable protecting piglets salmonellosis during period high risk infectio...
