Isolation of Lactobacilli-Phage and Its Biological Characteristics

Isolation of Lactobacilli--phage and its biological characteristics.

Lactobacilli, a well-known member of the oral microbiota, are chiefly classified in terms of their biological characteristics [1]. Need is felt for a more detailed classification of lactobacilli so as to clarify an exact role which is played by this bacterial species in the incidence of dental caries. Along this direction, Shiratsuchi[2] succeeded in classifying Lactobacilli into 2 main divisio...

Isolation and characterization of a phage active against streptomyces griseus

Isolation of antibiotic-resistant lactobacilli.

Numerous studies have been concerned with effects of orally administered antibiotics upon the numbers and kinds of microorganisms in the feces of man, but the influence of antibiotics upon intestinal lactobacilli, shown by changes in the numbers and kinds of these bacteria in feces, has not been thoroughly investigated. Enumeration and isolation of fecal lactobacilli have been facilitated by th...

Phage Isolation and Investigation

A novel bacteriophage, named phage #3, that infects several major strains of Pseudomonas aeruginosa has been discovered. The phage has a lambdoid morphology as seen by electron microscopy. Its nucleic acid is double stranded DNA and is 10-15 kb in length. Phage immunity tests have shown that the phage is temperate. The phage has been used to mediate transduction in the reconstruction of mutants...
