Colicine Production as an Epidemiological Marker of Escherichia Coli

Colicine-susceptibility patterns of enteropathogenic Escherichia coli.

Bacteriophage typing as an epidemiological tool for urinary Escherichia coli.

Phage typing was used to identify strains of Escherichia coli isolated from urinary and nonurinary sources. When eight phages isolated in Pennsylvania were used to type 717 cultures from Missouri, 50.3% of 624 urinary isolates and 34.4% of 93 nonurinary isolates were typable. Strains from nonurinary sources were not found commonly in urine. When five additional phages isolated in Missouri were ...

A method for typing Shigella sonnei, using colicine production as a marker.

Infection with Shigella sonnei is the most common identifiable cause of diarrhoea in this country at present, and the absence of a satisfactory method of typing the organism has greatly hampered the study of its mode of spread. Bojlen (1934), studying the biochemical reactions of 1,786 Sonne cultures, isolated from 741 patients in Denmark, described four biochemical types based upon the ferment...

Production of MAG1 Antigen of Toxoplasma gondii in Escherichia coli

  Introduction : Toxoplasmosis is a parasitic infection caused by the protozoan Toxoplasma gondii it leads to serious medical problems in congenitally-infected and immunocompromised individuals, while it is quite harmless in immunocompetent individuals. Toxoplasma tissue cyst matrix protein (MAG1) induces early humoral and cell-mediated immune responses. Previous studies suggested recombinant M...
