Plain-English summary
A dog in southern Thailand died from leptospirosis, a serious infection caused by bacteria called Leptospira. During an investigation of the outbreak, researchers found the bacteria in the dog's kidney and in soil samples from the area. They identified a new strain of the bacteria that was responsible for the dog's illness, which suggests it may have unique characteristics compared to other known strains. This information can help veterinarians understand and manage leptospirosis outbreaks in the future.

Abstract
We performed Leptospira culture analysis of 76 clinical samples collected from animals and of six soil samples for the investigation of a leptospirosis outbreak in southern Thailand in 2017. Leptospires were recovered from a kidney sample (a fatal canine leptospirosis case) and from all the soil samples. Next, 16S rRNA sequence analysis demonstrated that the clinical isolate was closely related to the pathogenic L. interrogans, whereas the soil isolates represented different species, including pathogenic L. ellisii, intermediate L. wolffii, and nonpathogenic L. yanagawae. Multilocus sequence typing identified an isolate of L. interrogans as a novel sequence type (ST263), suggesting that the causative agent of the canine leptospirosis in the southern Thailand outbreak has a unique genetic profile.
