results electron microscopy showed mrsa phages’ resemblance to members of the family siphoviridae, serogroups a and f. they exhibited a latent period of 70 minutes and a relatively burst size of 2,400 plaque-forming units (pfu)/infected cell. the titer of the phages was determined to be 3 × 109 pfu/ml using the by dla technique. conclusions in this study, two phages from the family siphoviridae...

By marker rescue of bacteriophage SP02 sus mutants with purified bacteriophage SP02 DNA fragments, 11 of the 17 known bacteriophage SP02 sus loci were assigned to discrete DNA fragments. The left-most genetic locus, susA, was found to reside near one bacteriophage SP02 terminus (EcoRI-C1 fragment), whereas the right-most genetic locus, susP, was found to reside near the other bacteriophage SP02...

Bacteriophage vB_Eco_swan01 was isolated from an ornamental pool using Escherichia coli MG1655 as the host. Bacteriophage vB_Eco_swan01 has limited similarity with other known phages at the nucleotide level and likely represents a new bacteriophage species within the Tunavirinae.

Classical and El Tor strains of Vibrio cholerae were examined for production of bacteriophage or bacteriophage-related material by electron microscopy of mitomycin C-induced cultures. The strains were also tested for pathogenicity by using the ligated ileal loops of adult rabbits. Of the 27 strains tested, 25 showed a correlation between the production of bacteriophage-related material and path...

Phage-peptides were prepared from L. lactis ssp. lactis ml3 and L. plantarum yit0068 bacteriophage using a ficin hydrolysis. The ml3 and yit0068 peptides were compared to L. lactis ssp. lactis c2 bacteriophage peptides to determine growth inhibition of C2 host and inhibition of both ml3 and c2 bacteriophage. M17 with .011 mM CaCl2 media with and without phage peptides (2 or 2.5%) were heat trea...

Staphylococcus aureus is a major cause of human and animal infections. Bacteriophage are a class of mobile genetic element (MGE) that carry virulence genes and disseminate them horizontally, including Panton-Valentine leukocidin (PVL), the immune evasion cluster (IEC) associated with human specificity, and enterotoxin A the major toxin associated with food poisoning. S. aureus isolates group in...

For the past three years a study of bacteriophage in its relation to Bact. diphtheriae has been in progress in this laboratory. Incidental to this study observations have been made on the occurrence of the lytic principle active upon this bacterium, with results which somewhat extend our knowledge of the distribution of bacteriophage in general, for it would hardly seem that the conditions gove...

Bacteriophages are viruses that can infect and kill bacteria. Three studies were conducted to determine the efficacy of bacteriophage to prevent an Escherichia coli respiratory infection in broiler chickens. In the first study 3-d-old-birds were challenged with an air sac inoculation of 10(3) cfu of E. coli per mL mixed with either 10(3) or 10(6) pfu of bacteriophage, or 10(4) cfu E. coli mixed...
