Serogroups and genotypes of Leptospira spp. strains from bovine aborted foetuses.
Leptospirosis is a global disease of animals, with potential major economic impact on livestock industry and important zoonotic capacities. The disease represents a major challenge in the developing countries as humans and animals frequently live in close association. The serovar Hardjo of Leptospira whose primary host is cattle has been studied extensively, but few data exist on other current circulating or emerging serotypes. To better understand the disease in cattle and how to prevent and/or control it, it is necessary to identify the genotype and the serotype of circulating Leptospira. This study presents results of several investigations performed on a historical Belgian collection of congenital jaundice in bovine aborted foetuses coming from the leptospirosis emerging episode of 2014 (Delooz et al., Transboundary and Emerging Diseases, 62, 2015, 124). The results revealed that L. Grippotyphosa and L. Australis were the most prevalent serogroups with, respectively, 17/42 and 13/42 positive microscopic agglutination test (MAT) during this emerging event associated with the same clinical pattern. The study also confirms that congenital jaundice is associated with L. kirscheneri and L. interrogans and provides the genotyping of DNA obtained from these two species.
