Subclinical bovine coccidiosis is an economic problem worldwide because they appear normal outwardly, but developmental stages damage the absorptive surface of the intestine and weaken the immune system. Information on the occurrence, diversity and economic losses due to Eimeria infection in cattle is lacking in Al-Baha area. The objective of this work was to study prevalence of subclinical bovine coccidia, throughout Al-Baha area and to evaluate various factors that might potentially influence prevalence and rate of pathogen excretion. A cross sectional study was conducted from July 2014 up to Jun 2015. Out of the total 534 fecal samples examined for Eimeria, 167 (31.27%) were found infected with eight species of Eimeria. Eimeria bovis was found to be the highest frequent species (25.84%), followed in order by E. zuernii (20.78%), E. ellipsoidalis (13.11%), E. canadensis (10.86%), E. alabamensis (8.05%), E. auburnensis (7.78%), E. cylindrica (5.43%), and E. subspherica (2.06%). Young cattle (≤12 month old) had significantly higher infection (P<0.01) of Eimeria. Higher infection of Eimeria was observed in female cattle compared to male ones. Co-infection was commonly present and declined with host age. Positive pair-wise associations were found between Eimeria species. In conclusion, this study was confirm that farm management frequently does not meet the requirements of effective coccidian control and the pathogenic coccidian, E. bovis and E. zuernii are the highest prevalent species in Al-Baha cattle populations. Further epidemiological investigations are required to investigate the different agro-ecological risk factor on the occurrence of bovine coccidiosis.

“…Such an example are Eimeria protozoan. To date there have been eleven species of Eimeria recorded in B. bonaus (Pyziel and Demiaszkiewicz 2009 b;Pyziel et al 2011;Pyziel unpublished), however, before 2009, there was no knowledge about the presence of these parasites in European bison. Similarly, the genera Toxoplasma, Cryptosporidium and Giardia have been recorded once only or even indirectly using molecular methods (Paziewska et al 2007;Majewska et al 2010) and we can suspect that future studies can improve the list of parasites.…”

During the last century the recorded parasite fauna of Bison bonasus includes 88 species. These are 22 species of protozoa, 4 trematode species, 4 cestode species, 43 nematode species, 7 mites, 4 Ixodidae ticks, 1 Mallophaga species, 1 Anoplura, and 2 Hippoboscidae flies. There are few monoxenous parasites, the majority of parasites are typical for other Bovidae and Cervidae species and many are newly acquired from Cervidae. This is an evident increased trend in the parasite species richness, in both the prevalence and intensity of infections, which is associated with the bison population size, host status (captive breeding or free-ranging) and the possibility of contact with other ruminant species. In light of the changes to parasite species richness during the last decades, special emphasis shall be given to new parasite species reported in European bison, their pathogenicity and potential implications for conservation.

“…They increasingly utilise open areas in the vicinity of forest habitats, especially in winter, to compensate for scarcity of graze within forest habitats due to the bisons' adaptations for open or mixed habitats and its hypothesised 'refugee' status in forests Bocherens et al 2015). This also reduces bison density at feeding sites and thereby reduces parasite loads (Radwan et al 2010;Pyziel et al 2011). In effect, this leads to humanwildlife conflict and bison disturbance because bison damage farm crops, such as winter green rape and cereals, and hay stored by farmers on meadows that were mown to obtain European Union (EU) subsidies.…”

Context Patch use can illustrate the contributions that forage quality and foraging risk make in shaping foraging decisions made under the risk of being killed. Objectives We aimed to determine whether forage selection by European bison Bison bonasus was state-dependent in being shaped by risk (wolf predation or human poaching/culling avoidance) or nutrient quality at two time periods-early winter (when resources are abundant) and at the end of winter (when resources are scarce)-in Białowie_ za Primeval Forest (Poland). Methods We used a giving-up density framework using the proportional consumption of hay provided by humans to measure the perceptions of risk in European bison. Results European bison resource selection was primarily driven by minimising the distance they travel over open ground in early winter (i.e. avoiding humans), however by the end of winter, when resources are scarce, bison selected haystacks for their nutrient quality (low fibre, high Mg and energy). Conclusions This study illustrates how resource selection varies according to the condition of animals (i.e. state-dependency affects the marginal value theorem). It also indicates conservation managers using hay quality may actively manage human-bison conflicts in trouble spots and that bison are currently free from top-down limitation in Białowie _ za as they do not perceive wolves as threatening enough to alter their foraging behaviour.
