“…The epizootiological importance of the European brown hare is based on the fact that it is a species maintaining the so-called home range (Kunst et al, 2001), being thus prone to many infectious diseases of natural nidality (Pikula et al, 2003(Pikula et al, , 2004(Pikula et al, , 2005. As a part of the monitoring of tularaemia occurrence in the European brown hare in South Moravia, we collected blood sera from shot specimens and examined them for the presence of antibodies against Francisella tularensis, Brucella suis and leptospires in 2004, 2005 and 2006. …”

There has recently been a growing interest in checking the state of health of European brown hares in hunting grounds because they are a susceptible bio-indicator of environmental changes and because of the dramatic decline in populations across Europe. A total of 1 051 (384, 302, and 365, respectively) blood sera were collected from hares during autumn hunting events and examined for tularaemia, brucellosis and leptospirosis in 2004, 2005 and 2006. Antibodies were found in 6.5, 1.6 and 7.5% of cases, respectively. Antibodies against Francisella tularensis, Brucella suis and leptospires were found in 7.9, 1.7 and 7.7% of females and 4.5, 1.4 and 7.9% of males, respectively. Higher seroprevalence of tularaemia was found in females (P = 0.05). Brucellosis was more prevalent in adult animals compared to subadult ones (P = 0.05). Only the L. grippotyphosa serotype was found and the titres mostly ranged from 100 to 400 (89.9%). Higher titres from 800 to 3 200 were found in the remaining 10.1% of the examined European brown hare sera. Antibodies against F. tularensis as well as B. suis were most frequent in low titres of 10 to 80. Higher titres were only exceptional. Confirming that hares are susceptible to various zoonotic agents, it is necessary to be careful when handling the animals killed. On the other hand, blood sera from hares may be used to survey the occurrence of natural nidi of zoonoses in hunting grounds.

“…the common vole -Microtus arvalis), like in the brucellosis and European hare, population density independence was also found (Pikula et al, 2002). The independence of natural foci of brucellosis on the European hare population density can be hypothetically explained by the existence of the so-called home ranges in this species (Kunst et al, 2001). The disease is either present in the environment of the European hare posing a threat of contracting the infectious agent independently of its population density or the territory is brucellosis-free.…”

A geographic information system was used for the analysis of ecological conditions of distribution of natural foci of brucellosis in the European hare (Lepus europaeus) and their long-term persistence in the Czech Republic. The European hare is a reservoir host of Brucella suis biotype 2. A close correlation was found between the geographic distribution and numbers of natural foci of brucellosis in the Czech Republic in 1971 to 1985 and 1986 to 2000 (r = 0.65, n = 814, P = 0.01). Natural foci of brucellosis were persistent, but not stationary, over the period of 30 years. Natural foci of brucellosis were most abundant in habitats of beech forests and the mosaic of fields and forests (x b = 3.19 and 2.95, respectively), geographic areas of 201-400 m of elevation above sea level (x b = 2.53), 0.0-2.0°C of mean annual air temperature (x b = 3.62), 1 401-1 800 mm of mean annual precipitation (x b = 4.52), 1 601-1 800 h of mean annual sunshine duration (x b = 2.64), and areas of the European hare population density of 51-100 individuals per 10 km 2 (x b = 3.33). Natural foci of brucellosis seem to be independent of the population density of European hare.

“…As some new natural foci of tularemia were quite far from the previously known ones, it cannot be explained by migrations of reservoir animals represented by small rodents and European brown hare (Lepus europaeus). Small rodents such as common vole (Microtus arvalis) are not capable of such long distance migrations (Zapletal et al, 2001) and European brown hare is a species maintaining the so-called home range of about 30-100 ha (Broekhuizen and Maaskamp, 1982;Reitz and Leoanrd, 1994;Kunst et al, 2001). Tularemia is either present in the given area or the territory is tularemia-free.…”

ABSTRACT:In the last decade, apart from the rise of numbers of positive hares and infected humans, we have been witnessing some spread of natural foci of tularemia into more northern areas of Southern Moravia, Czech Republic. It was, therefore, the aim of this paper to evaluate the spatio-temporal development of tularemia in Southern Moravia (in a selected study area of 130 × 90 km) using a geographic information system. Correlation analysis resulted in finding that the geographic distribution of natural foci of tularemia in any year correlated with the distribution in any other year of the study period of 1994-2001. The coefficients of correlation of all possible combinations of distribution in years 1994-2001 vary from 0.38 to 0.96 (n = 3 700, P = 0.01). The closer the years, the greater the correlation of distribution of tularemia. It can be stated that, in the study area during the period of eight years, tularemia persisted rather in the same locations but, as the coefficients of correlation do not equal 1.0, some variation in the distribution could be observed.
