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...
Background and Objective: Phage therapy could be used as an alternative method to antibiotic treatments. The purpose of this study was to evaluate the antibacterial activities of isolated lytic bacteriophage against ciprofloxacin-resistant strain of Salmonella infanits in vitro conditions. Materials and Methods: The standard strain of Salmonella infantis and its specific bacteriophage was iso...
three experiments were carried out for isolation of bacteriophage against growth reducing enterococcus faecalis and evaluation of its efficacy to control enterococci colonization in intestine of japanese quails. in experiment one, 60 enterococci spp were isolated from gastrointestinal contents of adult quails, which among them seven isolates were selected based on preliminary tests. in experime...
bacteriophage is a kind of virus that infect bacteria, and is distinct from the animal and plant viruses that could have either lytic or lysogenic cycle. lytic phages known as candidates for phage therapy, since they rapidly replicate into their host and lyse them. theoretically, phages have more than a few benefits over routine antibiotics. they are extremely specific and for their targeted ho...
Introduction: Bacteriophages are viruses that infect and destroy prokaryote cells, specifically the bacteria. They act too selective, so as each bacteriophage affects only on specific type of bacteria. Due to their specific features, bacteriophages can be used as an appropriate substitute for antibiotics in infectious diseases treatment. Therefore, this study aimed to isolate E. coli-specific b...
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 present study was focused on the pathosystem pepper plants (Capsicum annuum L.)-phytopathogenic bacterium X. euvesicatoria (wild strain 269p)-bacteriophage BsXeu269p/3 and possibility of bacteriophage-mediated biocontrol disease. Two new model systems were designed for monitoring effect phage treatment infectious process in vivo. spread bacteriophage pathogen monitored by qPCR. A pair prime...
Background and purpose: Activation-induced cytidine deaminase (AID) is a B-cell specific enzyme responsible for somatic hypermutation (SHM) and class switch recombination (CSR) of antibody genes within the B-cell follicle of peripheral lymphoid organs. Ectopic overexpression of the enzyme leads to mutations in non-B cells and Escherichia coli (E.coli) genes. However, induction of mutations in E...
conclusions according to the results, six strains were resistant to six or seven antibiotics and all strains were at least resistant to two antibiotics. however, for each of these resistant bacteria one bacteriophage was isolated from environmental samples, which showed the effectiveness of bacteriophages to remove clinically resistant e. coli strains. effective phages in vitro showed effective...
In this study, a novel Escherichia coli-specific bacteriophage, vB_EcoM_IME392, was isolated from chicken farm sewage in Qingdao, China. The genome of IME392 found by next-generation sequencing to be 116,460 base pairs length with G+C content 45.4% (GenBank accession number MH719082). BLASTn results revealed that only 2% the sequence shows similarity known phage sequences GenBank database, whic...
