Preliminary Characterization of Dog Derived Pathogenic Strains of Leptospira interrogans Serovar Australis in Nanchang of Jiangxi Province, China

Leptospirosis is a global zoonotic disease caused by pathogenic Leptospira, and those infected animals will show a variety of clinical symptoms and even death. The discovery of endemic strains is crucial to produce effective vaccines. In this study, we report that a strain of Leptospira, isolated fr...

description Leptospirosis is a global zoonotic disease caused by pathogenic Leptospira, and those infected animals will show a variety of clinical symptoms and even death. The discovery of endemic strains is crucial to produce effective vaccines. In this study, we report that a strain of Leptospira, isolated from a dog, is pathogenic. Using MLST analysis, the serovar of isolated Leptospira was identified and found it belongs to Leptospira interrogation Serovar Australis. Then, the virulence of this strain was researched by using hamsters. After infection, all the hamsters died within 4–5 days. Typical pathological changes were found in the liver, kidney, and lung of hamsters. These results all indicated that the isolated Leptospira was pathogenic. Thus, this study facilitates to identifying local Leptospira strains and develop a more targeted canine Leptospira vaccine.
