  • Title: Proticine typing of serologically defined Proteus strains.
    Author: Csiszár K, Lányi B.
    Journal: Acta Microbiol Acad Sci Hung; 1981; 28(1):111-8. PubMed ID: 7020353.
    Abstract:
    Serologically defined Proteus strains including 120 P. vulgaris, 356 P. mirabilis, 47 P. morganii, 36 P. rettgeri and 66 P. inconstans cultures isolated from a wide variety of sources, were classified by proticine (bacteriocine) typing. Using Cradock-Watson's set of indicator and producer strains, the isolates were tested for proticine production (P type) and for proticine sensitivity (S type). P. vulgaris was typable by the P method in 4.1%, by the S method in 41.6%. The respective percentages for P. mirabilis were 60.1 and 48.9. Most strains of P. morganii, P. rettgeri and P. inconstans were untypable by both methods. A correlation has been demonstrated between P/S types and certain serogroups and serotypes of P. mirabilis. It has been concluded that, in combination with the determination of O and H antigens, the P/S method of proticine typing has a high differentiating value in the epidemiological tracing of P. vulgaris and P. mirabilis.
