Anti-leptospiral agglutinins were found in the serum from 18 (7 species) of 419 (25 species) animals sampled from various areas of southeastern Australia. Positive serologic reactions were observed in 5 of 25 (20%) brush-tailed possum (Trichosurus vulpecula), 1 of 26 (3.8%) tammar wallaby (Macropus eugenii), 2 of 12 (16.7%) swamp wallaby (Wallabia bicolor), 1 of 3 (33.3%) koala (Phascolarctos cinereus), 3 of 41 (7.3%) common wombat (Vombatus ursinus), 2 of 100 (2%) bush rat (Rattus fuscipes) and 4 of 12 (25%) rusa deer (Cervus timorensis). The majority (55.5%) of serologic reactions were to serovar hardjo.
No serologic reactions were observed in samples from echidna (Tachyglossus aculeatus), brown antechinus (Antechinus stuartii), swainson’s antechinus (Antechinus swaisonsii), long-nosed bandicoot (Perameles nasuta), brown bandicoot (Isoodon obesulus), common ringtail (Pseudocheirus peregrinus), greater glider (Schoinobates volans), eastern grey kangaroo (Macropus giganteus), red-necked wallaby (Macropus rufogniseus), rabbit (Oryctolagus cuniculus), water rat (Hydromys chrysogaster), black rat (Rattus rattus), eastern swamp rat (Rattus lutreolus), broad-toothed rat (Mastacomys fuscus), fox (Vulpes vulpes), sambar deer (Cervus unicolor), hog deer (Axis porcinus) and fallow deer (Dama dama).
