“…At the same time, there was an increase in the number of positive reactions with the serovars copenhageni, polonica, and kabura. The latter two are the main aetiological factors of leptospirosis in cattle and small ruminants in Ukraine (Ukhovskyi et al 2014). We attribute their increase to the violation of segregation conditions (keeping animals separate).…”

Leptospirosis is a widespread infection among pigs throughout the world. In most cases in Ukraine, only the microscopic agglutination test (MAT) is used for the diagnosis of leptospirosis in animals. In general, during the period of 2001–2019, 2 381 163 samples of blood sera from swine were tested in our country and 85 338 positive reactions were received, which is 3.58% [binomial confidence intervals (BCI), 3.56–3.61%]. It was established that the serovars copenhageni – 33.91% (BCI, 33.59–34.23%), bratislava – 14.14% (BCI, 13.90–14.37%), pomona – 8.58% (BCI, 8.39–8.77%), and tarassovi – 7.12% (BCI, 6.95–7.30%) play a leading role in the aetiological structure of swine leptospirosis. A large number of positive reactions to several serovars was observed – 29.78% (BCI, 29.47–30.09%) of the total number of positive cases. In addition, the article presents data according to a retrospective analysis of the eight serovars circulating among pigs in Ukraine. Thus, during the nineteen year period, there was a decrease in the number of positive reactions to bratislava, pomona, and tarassovi and an increase in the number of positive reactions to copenhageni, polonica, and kabura. Mapping Ukraine’s territory for leptospirosis among pigs was carried out. This allows one to identify zones with a risk of leptospirosis infections among swine. The maps show that the highest incidence rates were identified in the eastern and central parts of Ukraine.

Three serogroups were sporadically reported, namely Cynopteri and Panama in 2018 only [85] and Pyrogenes in 2018 [85] and 2020 [96], even though these serogroups were tested in other studies [59,61,63,66,68,75,81,87,91].…”

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.

“…Leptospirosis is one of the most prevalent antropozoonotic infections in many countries of the world and in particular in Ukraine (Ukhovskyi et al, 2018). To date, there are over 250 leptospira serovars in 26 serogroups (Walker and Srinivas, 2013).…”

The most common serovars causing leptospirosis in dogs before the introduction of leptospirosis vaccine 30 years ago were Canicola and Icterohaemorrhagiae.…”

Leptospirosis is an infectious natural-focal disease of many species of animals and human with a wide range of clinical signs. The most common serovars causing leptospirosis in dogs are Icterohaemorrhagiae and Canicola. Analyzing the epizootic situation concerning leptospirosis of carnivores in Ukraine, employees of the Laboratory of Leptospirosis of Institute of Veterinary Medicine of the National Academy of Agrarian Sciences have developed and produced successively three series of bivalent inactivated vaccine against leptospirosis of carnivores, taking into account the etiological structure of the disease of this animal species. The paper presents the results of the study of three experimental series of inactivated polyvalent vaccine against leptospirosis of carnivores regarding: pH, sterility, residual amounts of inactivant, completeness of inactivation, harmlessness and immunogenic activity. It has been established that according to the indicators of sterility, completeness of inactivation, residual amount of inactivant, harmlessness and concentration of hydrogen ions, all three series of vaccine meet the requirements and norms of normative documentation. Intravenous administration of all three experimental series of the vaccine to the experimental rabbits provided the formation of specific anti-leptospirosis antibodies in the titers corresponding to the parameters of the immunogenicity norms established in the technical conditions of the drug.
