Characterization of bacteriophages infecting multidrug-resistant uropathogenic Escherichia coli strains.

Uropathogenic Escherichia coli (UPEC) is the most common causative agent of urinary tract infections, and strains that are resistant to antibiotics are a major problem in treating these infections. Phage therapy is a promising alternative approach that can be used to treat infections caused by polyresistant bacterial strains. In the present study, 16 bacteriophages isolated from sewage and surface water were investigated.

Endolysin EN572-5 as an alternative to treat urinary tract infection caused by Streptococcus agalactiae.

Streptococcus agalactiae (Group B Streptococcus, GBS) is an opportunistic pathogen causing urinary tract infection (UTI). Endolysin EN572-5 was identified in prophage KMB-572-E of the human isolate Streptococcus agalactiae KMB-572. The entire EN572-5 gene was cloned into an expression vector and the corresponding recombinant protein EN572-5 was expressed in Escherichia coli in a soluble form, isolated by affinity chromatography, and characterized.

Successful use of a phage endolysin for treatment of chronic pelvic pain syndrome/chronic bacterial prostatitis.

Chronic prostatitis (CP) is a common inflammatory condition of the prostate that is estimated to effect 2%-10% of the world's male population. It can manifest as perineal, suprapubic, or lower back pain and urinary symptoms occurring with either recurrent bacterial infection [chronic bacterial prostatitis (CBP)] or in the absence of evidence of bacterial infection [chronic pelvic pain syndrome (CPPS)]. Here, in the case of a 39 years-old CBP patient, we report the first successful use of a bacteriophage-derived muralytic enzyme (endolysin) to treat and resolve the disease.

PHERI-Phage Host ExploRation Pipeline.

Antibiotic resistance is becoming a common problem in medicine, food, and industry, with multidrug-resistant bacterial strains occurring in all regions. One of the possible future solutions is the use of bacteriophages. Phages are the most abundant form of life in the biosphere, so we can highly likely purify a specific phage against each target bacterium.

Complete Genome Sequence of Cronobacter dublinensis Bacteriophage vB_Cdu_VP8.

Cronobacter dublinensis is a Gram-negative pathogen that is capable of causing infection in humans. In this announcement, we describe the characterization of bacteriophage vB_Cdu_VP8, which is able to lyse a Cronobacter dublinensis strain. Related to phages belonging to the genus , such as Muldoon and SP1, vB_Cdu_VP8 contains 264 predicted protein-coding genes and 3 tRNAs.
