Bacteriocine typing of Proteus.
نویسنده
چکیده
A method of typing isolates of Proteus mirabilis and Proteus vulgaris is described based on the sensitivity of the organisms to bacteriocine. Twelve standard proteocine producing strains were selected from a large number of isolates tested, and from these liquid proteocine preparations were prepared. The sensitivities of 1805 isolates to these 12 preparations were then determined and none was found to be untypable. From the results a bacteriocine typing system has been developed.

An evaluation of three methods of typing organisms of the genus Proteus.
An assessment of three simple methods of typing Proteus strains is described. The methods chosen were biochemical typing, bacteriocine typing, and typing by means of the Dienes phenomenon. Dienes typing was deemed to be superior to biochemical typing and bacteriocine typing.A brief discussion on the relationship between the Dienes phenomenon and bacteriocine production is appended.
متن کاملAn evaluation of two methods of bacteriocine typing of organisms of the genus Proteus.
An assessment of two simple methods of typing Proteus isolates using bacteriocines is described. The methods chosen were those of Cradock-Watson and Al-Jumaili. It has been shown that the use of liquid bacteriocine preparations is more satisfactory than methods involving proteocine production in solid media. For example, no non-typable isolates were encountered and a large number of strains wer...
متن کاملComparison of different media for bacteriocine typing of Proteus mirabilis.
The effect of a variety of nutrient bases on the production of bacteriocines by 10 standard Cradock-Watson types of Proteus mirabilis has been investigated. Differences in yield of greater than 10,000 fold were observed. Maximum yields were obtained with proteose peptone no. 3 (Difco) and a medium containing this with oxgall (Difco) as an antiswarming agent was developed for routine typing.
متن کاملBacteriocine typing of Klebsiella spp.
One hundred and six strains of Klebsiella spp were examined for their ability to produce bacteriocine. Nine of these, together with one strain from the National Collection of Type Cultures, were selected and used to type Klebsiella strains from various sources. Strains were typed by testing their sensitivity to bacteriocines produced by the standard set of 10 strains. Eight hundred strains were...
متن کاملIdentification of Proteus Species
SYNOPSIS The properties and characteristics of 296 Proteus strains isolated from hospital patients and from sewage have been examined with a view to determining those characters which are of most use in following and detecting cross-infection. Ninety-six per cent of the organisms isolated were P. mirabilis and it was found that by identifying biotypes and by phage typing the species could be di...
