Background And Objectives: Multi-drug-resistant is associated with various infectious diseases that cannot be easily treated by antibiotics. However, bacteriophages have potential therapeutic applications in the control of multi-drug-resistant bacteria. In this study, we aimed to isolate and characterize of a lytic bacteriophage that can lyse specifically the multi-drug-resistant (MDR)
Materials And Methods: Lytic bacteriophage was isolated from Qaem hospital wastewater and characterized morphologically and genetically. Next-generation sequencing was used to complete genome analysis of the isolated bacteriophage.
Results: Based on the transmission electron microscopy feature, the isolated bacteriophage (vB-Ea-5) belongs to the family . vB-Ea-5 had a latent period of 25 minutes, a burst size of 13 PFU/ml, and a burst time of 40 min. Genome sequencing revealed that vB-Ea-5 has a 135324 bp genome with 41.41% GC content. The vB-Ea-5 genome codes 212 ORFs 90 of which were categorized into several functional classes such as DNA replication and modification, transcriptional regulation, packaging, structural proteins, and a host lysis protein (Holin). No antibiotic resistance and toxin genes were detected in the genome. SDS-PAGE of vB-Ea-5 proteins exhibited three major and four minor bands with a molecular weight ranging from 18 to 50 kD.
Conclusion: Our study suggests vB-Ea-5 as a potential candidate for phage therapy against MDR infections.

Bacteriophages are promising alternatives for combating multidrug-resistant bacterial infections. Two lytic bacteriophages, named P1 and P3, targeting pathogenic Escherichia coli (ExPEC; strain TZ1_3) were isolated and evaluated for their potential ability to control pathogenic numbers either in ExPEC-contaminated food or ExPEC-infected mice. Results showed that phages significantly reduced ExPEC numbers within 6 and 12 h in contaminated water, milk, beef, and chicken when applied at 10 plaque-forming units (PFU).

Bovine mastitis is a considerable challenge within the dairy industry, causing significant financial losses and threatening public health. The increased occurrence of methicillin-resistant Staphylococcus aureus (MRSA) has provoked difficulties in managing bovine mastitis. Bacteriophage therapy presents a novel treatment strategy to combat MRSA infections, emerging as a possible substitute for antibiotics.

Background: Viruses that infect prokaryotes (phages) constitute the most abundant group of biological agents, playing pivotal roles in microbial systems. They are known to impact microbial community dynamics, microbial ecology, and evolution. Efforts to document the diversity, host range, infection dynamics, and effects of bacteriophage infection on host cell metabolism are extremely underexplored.
