“…However, this explanation is in contradiction with the high prevalence registered in this study for some direct life-cycle parasites, such as GI nematodes and Eimeria. The absence of herpesvirus and pestivirus in this study coincides with the low prevalence detected by Boadella et al (2010) in previous studies in Spain or by Candela et al (2014) in France and reflects a relative isolation of roe deer from domestic animals.…”

“…These results suggest that the transmission of the disease is not effective considering the living conditions of the roe deer from Spain. Compared to T. gondii, definitive hosts are supposed to shed a lower number of N. caninum oocysts and the range of intermediate hosts is less wide (Dubey & Schares 2011;Candela et al 2014). Consequently, the horizontal transmission of this protozoan might be more limited.…”

In order to provide up-to-date information about the prevalence of infectious and parasitic agents in Spanish roe deer (Capreolus capreolus), samples from 93 animals hunted from January 2013 to April 2015 were collected and analysed by parasitological, serological and molecular techniques. Sampled animals came from four roe deer populations corresponding to Oceanic, Continental, Mediterranean and Mountainous ecosystems of Spain. Data regarding sex, age and year were also considered. A high percentage of roe deer (95.7%) resulted positive for at least one agent. Sarcocystis spp. was the most frequently diagnosed genus (88.8%), followed by gastrointestinal nematodes (62.9%) and Schmallenberg virus (53.5%). Varestrongylus capreoli (38%), Anaplasma phagocitophylum (34.2%), Eimeria spp. (29.2%), Toxoplasma gondii (25%) and Cephenemyia stimulator (23.8%) displayed medium prevalences and, finally low percentages were registered for Moniezia spp. (6.7%), Dictyocaulus noerneri (2.4%) and Mycobacterium avium subsp. paratuberculosis (1.5%). No infections by Neospora caninum, Bovine herpesvirus, pestivirus or Coxiella burnetii were found. Climate was significantly associated with the prevalence of T. gondii, C. stimulator and A. phagocitophylum, with higher prevalences in animals from Oceanic and Mediterranean areas. Our results suggest that infections affecting Spanish roe deer, especially those of parasitic aetiology, represent one of the causes of the descent in the abundance of this ungulate in the last years. Moreover, the high prevalence of zoonotic agents such as T. gondii and A. phagocitophylum could also have a great relevance in the environmental and/or Public Health. ARTICLE HISTORY

“…serological status e sex Â age class þ annual rainfall þ cold temperature þ home range size þ woodland þ dwellings An interaction between sex and age class was assumed on the basis of a previous study (Candela et al 2014). The variable "cold temperature" was built as the number of days with a minimum temperature equal to or below −6°C during the year before blood sampling (Table 2), as this temperature is the threshold under which oocyst sporulation is no longer possible (Dumètre and Dardé 2003;Beral et al 2012).…”

Does land use within the home range drive the exposure of roe deer (Capreolus capreolus) to two abortive pathogens in a rural agro-ecosystem?

The recent increase in interactions between wildlife and domestic animals has heightened the risks of transmission of pathogens between wildlife, livestock, and humans. Our objective was to better understand how the spatial behavior of wildlife impacts their exposure to pathogens. We carried out a 5-year serological survey of Toxoplasma gondii and Chlamydia abortus in a roe deer population (Capreolus capreolus) living in a rural landscape and monitored using GPS technology. We tested whether the apparent seroprevalence of these pathogens was related to the characteristics of roe deer's home range, indirectly reflecting the probability of contact between deer and domestic hosts (cats for T. gondii and ruminants for C. abortus). We controlled for the effects of temperature and rainfall, as local weather can affect pathogen survival in the environment. Overall, apparent seroprevalences were 43.7 and 15.8 % for T. gondii (N=135) and C. abortus (N=133), respectively. The apparent seroprevalence to T. gondii increased with the proportion of human dwellings (a proxy of cat presence) within the roe deer's core home range and was higher during mild and wet years. This result illustrates how the spatial behavior of wild animals can modulate their exposure to pathogens through the degree of spatial overlap with a domestic host. By contrast, apparent seroprevalence to C. abortus increased with the annual number of frosty days but not with the proportion of meadows occupied by domestic ruminants within the core home range. This suggests that the cycle of C. abortus in wild animals could be somewhat independent from that in livestock.

“…Z jednej strony, zwiększa ono szansę przeżycia w niekorzystnych warunkach, z drugiej jednak, może potęgować ryzyko zarażeń (31). Wśród patogenów pasożytniczych zwierząt wolno żyjących stwierdzana jest także liczna grupa gatunków zoonotycznych (1,4,8). W tym znaczeniu jest to naturalny rezerwuar patogenów człowieka i innych zwierząt, który powinien być stale monitorowany.…”

Inwazje pasożytnicze zwierząt wolno żyjących charakteryzują się specyficznymi uwarunkowaniami inwazjologicznymi. Wynikają one z naturalnych zależności występujących w określonej biocenozie. Stały kontakt zwierząt ze środowiskiem naturalnym, będącym rezerwuarem form inwazyjnych wielu pasożytów powoduje, że u żywicieli wolno żyjących często obserwuje się znacznie bogatszą faunę pasożytniczą niż u ich udomowionych krewnych. W przypadku braku ingerencji człowieka najważniejszym czynnikiem warunkującym występowanie i przebieg parazytoz tej grupy zwierząt staje się zależność środowiskowa. Z tego względu inwazje cechują się najczęściej wyjątkową różnorodnością i endemiczną specyficznością. Nie bez znaczenia są również pewne uwarunkowania lokalne. W kontekście Lubelszczyzny jest to niewielka liczebność zasobów leśnych okolic Lublina oraz brak bezpośredniej komunikacji z dużymi obszarami leśny-mi pozostałych części kraju. Czynniki te powodują, że wędrówki zwierząt są ograniczone, co wpływa na zachowawczy charakter wielu inwazji.

Internal parasites in roe deer of the Lubartów Forest Division in postmortem studiesSummary The aim of the study was to analyze endoparasitic fauna in roe deer of a selected area of south-western Poland using coproscopic studies and postmortem studies of internal organs (lungs, livers and digestive tracts). Microscopic methods included flotation and the McMaster method. In May and June 2015, 53 culled male roe deer were examined. Parasites were found in 96.2% (n = 51, SD = 19.2) of the studied animals, but the invasion intensity was diversified. From 1 to 7 different taxa (families or genera) of parasites were found in each studied animal. Oocysts of Eimeria (3 species (E. capreoli, E. panda, E. rotunda) were found with the following invasion prevalence: 45.28%, low OPG level, in the range of 350-700. In three samples, the OPG amounted to 2800--4500. Cysts of Buxtonella sulcata 9.4% (CPG in the range of 300-100). Fasciola hepatica (prevalence 3.77%), intensity: 2-3 specimens, Dicrocoelium dendriticum (5.66%), intensity: 2-5 specimens. Moniezia expansa (7.54%), intensity: 3-8 tapeworms. Nematodes from the family Trichostrongylidae (58.49%, genera: Ostertagia, Spiculopteragia, Haemonchus, Trichostrongylus and Nematodiurus from the family Molineidae), low invasion intensity (8-55 nematodes), only in 7 deer intensities of 346-140 nematodes). Capillaria bovis (7.54%) intensity ranging from 2 to 14 nematodes. Oesophagostomum venulosum (15.09%) invasion intensity: 7-23 nematodes, Trichuris globulosa (9.43%), invasion intensity 2-4 nematodes. Dictyocaulus eckerti (11.32%), invasion intensity ranging from 6 to 34 nematodes. Setaria tundra (5.66%) invasion intensity ranging from 1 to 3 nematodes.
