Characterization of myophage AM24 infecting Acinetobacter baumannii of the K9 capsular type.

In the present study, we investigate the biological properties and genomic organization of virulent bacteriophage AM24, which specifically infects multidrug-resistant clinical Acinetobacter baumannii strains with a K9 capsular polysaccharide structure. The phage was identified as a member of the family Myoviridae by transmission electron microscopy. The AM24 linear double-stranded DNA genome of 97,177 bp contains 167 open reading frames.

Draft Genome Sequences of 10 Clinical K2-Type Klebsiella pneumoniae Strains Isolated in Russia.

We report here the genome sequences of 10 Klebsiella pneumoniae strains of capsular type K2 isolated in Russia from patients in an infectious clinical hospital and neurosurgical intensive care unit. The draft genome sizes range from 5.34 to 5.

Comparative genome analysis of novel Podoviruses lytic for hypermucoviscous Klebsiella pneumoniae of K1, K2, and K57 capsular types.

Hypermucoviscous (HV) strains of capsular types K1, K2 and K57 are the most virulent representatives of the Klebsiella pneumoniae species. Eight novel bacteriophages lytic for HV K. pneumoniae were isolated and characterized.

Genome sequencing and comparative analysis of three hypermucoviscous Klebsiella pneumoniae strains isolated in Russia.

The prevalence and characteristics of hypermucoviscous (HV) strains among Klebsiella pneumoniae isolated in Russian hospitals were investigated. The HV strains accounted for 11% of the K. pneumoniae isolates collected in the period from 2011 to 2016, and were characterized as belonging to the K1, K2, K20 and K57 serotypes.

Complete genome sequence of novel T7-like virus vB_KpnP_KpV289 with lytic activity against Klebsiella pneumoniae.

A novel bacteriophage, vB_KpnP_KpV289, lytic for hypermucoviscous strains of Klebsiella pneumoniae, was attributed to the family Podoviridae, subfamily Autographivirinae, genus T7likevirus based on transmission electron microscopy and genome analysis. The complete genome of the bacteriophage vB_KpnP_KpV289 consists of a linear double-stranded DNA of 41,054 bp including 179-bp direct-repeat sequences at the ends and 51 open reading frames (ORFs). The G+C content is 52.

Isolation and characterization of wide host range lytic bacteriophage AP22 infecting Acinetobacter baumannii.

Acinetobacter baumannii plays a significant role in infecting patients admitted to hospitals. Many A. baumannii infections, including ventilation-associated pneumonia, wound, and bloodstream infections, are common for intensive care and burn units.

The genome sequence and proteome of bacteriophage ΦCPV1 virulent for Clostridium perfringens.

Application of bacteriophages and their lytic enzymes to control Clostridium perfringens is one potential approach to reduce the pathogen on poultry farms and in poultry-processing facilities. Bacteriophages lytic for C. perfringens were isolated from sewage, feces and broiler intestinal contents and ΦCPV1, a virulent bacteriophage, was classified in the family Podoviridae.
