“…Currently, the source of infection remains unknown and therefore complicates the usefulness of implementation of preventive measures. From the affected farms, only one case of bovine aborted foetus was identified in 95% of the farms with a maximum of three cases in one farm (Delooz et al., ). That allows hypothesizing that infection does not spread to the entire herd by other cattle that therefore do not appear to be potential maintenance hosts.…”

“…Since July 2014, the Belgian Walloon region faced an unexpected situation with a drastic increase of congenital jaundice in bovine aborted foetuses (Delooz et al., ). During the last 6 years, abortions associated with jaundice had been notified (Figure ) but the monthly incidence of cases remained stable.…”

“…In France, microscopic agglutination test (MAT) performed on samples collected in 394 cattle herds allowed to determine the distribution of the following three predominant circulating serogroups (Australis, Sejroe and Grippotyphosa) (Ayral et al., ). In this part of Europe, leptospirosis is prevalent and may be responsible for pathological events in human (Mori et al., ) and animal health (Delooz et al., ).…”

“…However, foetal jaundice was not observed during experimental infections (Ellis & Michna, ; Ellis, O'Brien, Neill, & Bryson, ; Smith et al., ). On the contrary based on the recent field observations, the hypothesis of the association of bovine foetal jaundice with leptospirosis was formulated (Delooz et al., ). Currently, little epidemiological information exists concerning the different serovars of Leptospira circulating among cattle in Belgium.…”

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.

Background: Leptospirosis is a zoonotic disease which is globally distributed. Bovine leptospirosis often results in economic losses through its severe impact on reproduction performance. However, a clear overview of the disease characteristics in European cattle is lacking. The objective of this review was to summarise the current knowledge and state of the research on the epidemiology of bovine leptospirosis in Europe. Methodology: We conducted a systematic literature review following the PRISMA guidelines. We screened four electronic databases (Pubmed, Web of Science, Scopus, CABI) and included studies published between 2001 and 2021, in English, German, and French. Identified papers were filtered according to predefined inclusion and exclusion criteria. Results: Sixty-two studies were included. Reported seroprevalences were remarkably variable among studies, probably reflecting local variations but also heterogeneity in the study designs, laboratory methods, and sample sizes. The five most reported circulating serogroups in European cattle were Sejroe, Australis, Grippotyphosa, Icterohaemorrhagiae, and Pomona. Abortion and fertility disorders were the most frequently reported signs of leptospirosis in European cattle and were generally associated with chronic infections. The acute form primarily affected juveniles and foetuses. Risk factors positively associated with leptospirosis in cattle were diverse, related to environmental (e.g. geographic location), climatic (e.g. flooding), and medical (e.g. presence of other diseases) parameters, as well as farming practices (e.g. purchase policy, herd size) and individual factors (e.g. animal age and breed). Conclusions: Clinical features of bovine leptospirosis in Europe cover a large range of signs and confirmation of infection requires laboratory tests. The epidemiology of the disease is very local, most probably influenced by context-specific factors. This work highlights several research gaps, including a lack of research data from several countries, a lack of methodological harmonisation, a lack of large-scale studies, an underrepresentation of beef herds in the studies, and a lack of molecular investigations.
