Abstract

sp. nov vaisolated from feces of dogs and humans and from surface water. The organisms gave the key biochemical reactions typical of species, including greater metabolic activity at 25 to 28°C than at 36°C. can be distinguished from other yersiniae by its positive reactions in tests for citrate and sucrose and negative reactions in tests for indole, acetoin (Voges-Proskauer), and rhamnose. Two biogroups were found among seven strains investigated, one of which fermented raffinose and melibiose. Deoxyribonucleic acid hybridization tests (hydroxyapatite method) showed average levels of relatedness of 93% at a 60°C incubation temperature and 97% at 75°C. Labeled deoxyribonucleic acid showed 30% to 63% relatedness to all species except . The guanine-plus-cytosine contents of five tested strains were 48.7 to 49.4 mol%. All strains possessed O antigens not typable with antisera of the extended typing scheme of Wauters, but most of them had H antigens typical of biotype 1. Five tested strains belonged to lysotype X. strains were susceptible to most antimicrobial agents; resistance or intermediate susceptibility was observed for ampicillin, carbenicillin, cephalothin, penicillin, and sulfonamide. Calcium dependency, autoagglutination, and Congo red pigmentation tests, which are indicative of the presence of a virulence plasmid to , were negative in . The clinical significance for humans and animals is uncertain and requires further study. The type strain of sp. nov. is strain H 271-36/78 (= CDC 3022-85 = ATCC 43380).
