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...
متن کاملColicine types of Shigella sonnei isolated in Hong Kong.
Two-hundred and twenty-five strains of Shigella sonnei isolated from sporadic cases of bacillary dysentery were subjected to colicine typing. The result showed that types 15 and 12 were the prevailing types in Hong Kong and two new types which did not fit in with the colicine patterns of the current types were observed. A marked increase in the numbers of strains concurrently resistant to chlor...
متن کاملColicin typing of Shigella sonnei.
The colicin typing method for differentiating epidemic strains of Shigella sonnei was evaluated. Forty percent of the strains were untypable, but the method divides 60% of the strains into 15 established colicin types. The method has reasonably good reproducibility, but should not be interpreted with the same degree of confidence as some other characteristics such as serotypes. For this reason,...
متن کاملBacteriophage typing of Shigella sonnei.
A bacteriophage-typing schema was developed for differentiating strains of Shigella sonnei. Sixty-seven bacteriophages were obtained from other collections, and 36 bacteriophages were isolated from sewage. From these 103 bacteriophages, a provisional set of 12 was chosen by computer analysis as being the most sensitive in differentiating strains of S. sonnei isolated in the United States. The p...
متن کاملComparison of four methods of differential typing of isolates of Shigella sonnei.
An epidemiological study of Sonne dysentery in Dundee during the years 1971-6 was made by examining, in respect of 1420 isolates of Shigella sonnei, the discriminating power of colicine typing, antibiogram testing, biotyping and resistotyping and the stabilty of the markers they provided. Colicine typing identified nine colicine types, including four not previously described. However, because t...
