The study was aimed at determination of bacterioenzymogenic activity of 351 Proteus strains (337 strains of Proteus mirabilis and 14 strains of Proteus Vulgaris) isolated in laboratory of Pediatric Institute of the Medical Academy in Lódź, mostly from urine (222 strains) and feces (99 strains). for determination of bacteriocinogenic properties, 15 index strains "S" were used. Of these, six were from collection of Senior (The University of Dundee Medical School, Scotland) and 9 from own Piatkowski collection (Lódź University). Detection of bacteriocinogenic strains and determination of their activity toward 15 index strains was performed by an own method (15). Out of total 551 strains tested, bacteriocinogenic properties were found in 263 (75%) of strains. Remaining 88 (25%) strains did not inhibit any of the 15 index strains. Sixty-two different types of bacteriocinogenicity were found. The results suggest that bacteriocinogenic typing of Proteus mirabilis strains permits for more precise characterization of properties of these bacteria useful for epidemiological purposes, than by application of other methods.

UI	MeSH Term	Description	Entries
D011513	Proteus mirabilis	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria that is frequently isolated from clinical specimens. Its most common site of infection is the urinary tract.
D005243	Feces	Excrement from the INTESTINES, containing unabsorbed solids, waste products, secretions, and BACTERIA of the DIGESTIVE SYSTEM.
D001430	Bacteriocins	Substances elaborated by specific strains of bacteria that are lethal against other strains of the same or related species. They are protein or lipopolysaccharide-protein complexes used in taxonomy studies of bacteria.	Bacteriocin,Lantibiotic,Lantibiotics
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.	Species Specificities,Specificities, Species,Specificity, Species
D014556	Urine	Liquid by-product of excretion produced in the kidneys, temporarily stored in the bladder until discharge through the URETHRA.
D015373	Bacterial Typing Techniques	Procedures for identifying types and strains of bacteria. The most frequently employed typing systems are BACTERIOPHAGE TYPING and SEROTYPING as well as bacteriocin typing and biotyping.
