| Popis: | Bacteriophage typing and serogrouping were carried out on 349 strains of Pseudomonas aeruginosa mainly from domestic animals. A new bacteriophage set for P. aeruginosa - which had been developed entirely on the basis of human strains - also worked satisfactorily in animal strains. The percentage of non-typable strains isolated from animals was 7.9 as compared to 4.5 in a previous examination on 486 human strains. Part of this investigation was carried out on isolates with known herd relationships, such that reservoir and transmission could be evaluated. In several instances, humans had infections with pseudomonas of the same phage typing pattern and serogroup characteristics as simultaneously caused infections in cattle. The ubiquitous nature of P. aeruginosa as a pathogen was shown. This induces interesting hypotheses regarding the zoonotic aspects of pseudomonas infections. No particular phage types were characteristic for any particular animal species, or type, or site of infection—a finding which relates well with the omnipresence of pseudomonas. The serogroup 0:6 was the most frequent among bovine and musteline strains, but this is in accordance also with the high frequency thereof in strains of human origin. The most frequent phage typing pattern was 8, 12, 16 and related patterns (8; 8, 12; 12; 16; 8, 16; 12, 16) which together was found in approximately 1/3 of the isolates. The significance of milking equipment as a reservoir and a vector of infection was indicated by the occurrence of the same bacterial types from equipment and from udders. |
