Isolation of specialized lambda transducing bacteriophages for flagellar genes (fla) of Escherichia coli K-12.
Specialized transducing lambda phages carrying the region III flagellar genes (fla) of Escherichia coli K-12 were isolated by a new method. A strain carrying both a cryptic lambda prophage near the his genes and a deletion of the attlambda gene was used as a starting strain. The lysogen of lambdacI857pga18-bio69 was isolated in which the prophage was integrated within the lambda cryptic genes b...
متن کاملIsolation of bacteriophages active against Neisseria meningitidis.
Five distinct bacteriophages have been isolated from strains of Neisseria meningitidis. Filtrates with titers of 10(-4) to 10(-6) were produced with a modified Swanstrom and Adams semisolid agar procedure, employing Eugonbroth with added agar and an incubation temperature of 30 C. Of 49 strains of N. meningitidis (groups B and C), 25 were lysed by one or more of the phages, but there was no lys...
متن کاملIsolation and characterization of bacteriophages for Neisseria.
Sixteen bacteriophages for several strains of Neisseria perflava were isolated from throat washings and lysogenic organisms. The phages are placed into five groups based on serological and host-range characteristics. Group I, host strain c r, has phages NI, N2, mutant N2C, N5, N6, and NI3. N I is virulent, all others temperate for the host. Plaque size is about 1.5 mm., the largest for Neisseri...
متن کاملEvaluation of Bacteriophages Methods for Detection and Isolation of Viruses from Surface Water
Detection methods of F-specific bacteriophages (FRNA), for removal of viral pollution and Somatic-Phages and fate, behavior and survival of viruses in the sediment evaluated and optimized in this research. The research focused mainly on evaluation of the different steps for culturing the host strain WG49 Salmonella Typhimurium. Salmonella typhimurium WG49 used for our analysis to act as host st...
متن کاملIsolation and characterization of Campylobacter bacteriophages from retail poultry.
The ability of phages to survive processing is an important aspect of their potential use in the biocontrol of Campylobacter in poultry production. To this end, we have developed a procedure to recover Campylobacter bacteriophages from chilled and frozen retail poultry and have validated the sensitivity of the method by using a characterized Campylobacter phage (i.e., NCTC 12674). By using this...
