“…Most articles describing type I alleles during genotyping ( Turčeková et al., 2013 ; Papini et al., 2015 ; Mancianti et al., 2015 ; Battisti et al., 2018 ; Santoro et al., 2020 ; Sroka et al., 2020 ) only involved direct genotyping from tissue samples DNA, with an often lower success in the amplification of typing markers. On the other hand, two studies ( Verma et al., 2015 ; Moskwa et al., 2017 ) showed a complete clonal type I profile in two isolates obtained from an aborted bovine fetus in Portugal [firstly reported by ( Canada et al., 2002 )] and from an aborted fetus of European bison ( Bison bonasus bonasus L. ) in Poland, respectively. Clonal type I isolates fully typed by 15 MS markers have been also described infecting humans ( Ajzenberg et al., 2010 ).…”

Toxoplasma gondii is a major zoonotic agent which may cause harmful effects mainly in pregnant and immunocompromised hosts. Despite many efforts on its genetic characterization, an entirely clear picture of the population structure in Europe has not been achieved yet. The present study aimed to summarize the available genotyping information and to map the distribution of circulating strains. There is consensus on type II T. gondii genotypes prevailing in Europe, but the absence of harmonization in the use of typing methods limits detailed knowledge. Standardized, high-end typing tools and integrative strategies are needed to fill the gaps and complete an accurate image of the T. gondii genetic population in Europe.

“…Only slightly higher T. gondii parasite seroprevalence was observed in European bison from Białowieża prior to the study of Krzysiak et al [46,59]. It was followed by the report of T. gondii isolation from an aborted at 4-5-monthold gestation of European bison fetus in Białowieża in 2014 [60]. Similar to T. gondii, European bison pose some potential as Neospora caninum and Chlamydia spp.…”

In 2019, the 90th anniversary of the restitution of European bison (wisent) will be celebrated. Therefore, the chapter discusses the past, present, and future health threats of the Bison bonasus species that was on the edge of world extinction at the beginning of the twentieth century and was restituted with great efforts from many researchers, breeders, forestry workers, and caretakers. Due to the dramatic genetic "bottleneck" that depleted the gene pool, increasing the inbred of today's European bison, the breeding may face problems of decreased fertility, deficiency in growth, and increased susceptibility to diseases. While the increasing numbers of European bison may be enjoyed by breeders, the suitable habitat for the largest herbivore in Europe shrinks with increasing human population density, forestry, and agricultural activity. Additional threats include inappropriate management based on animal farming rather than sylvatic ecosystems, need for supplementary winter feeding, and establishment of breeding of related species such as American bison (Bison bison) in Europe. The control of European bison exposure to pathogens through passive and active surveillance is a key component of the species conservation. Hereby, the current knowledge on the epidemiology of the most significant infectious diseases in European bison is presented.

“…This seroprevalence may be due to environmental contamination with T. gondii oocysts shed by domestic and wild felids [ 63 ]. Although there is currently no evidence that T. gondii infection has any clinical consequences in European bison, it may nevertheless represent a potential threat to reproduction, particularly since transplacental transmission has been confirmed: T. gondii genetic material has been isolated from the brain of an aborted European bison fetus from Bialowieza National Park [ 64 ]. Studies have noted high levels of T. gondii seropositivity in Polish wildlife: 21.4% of red deer, 37.6% of wild boar ( Sus scrofa ), and 30.4% of roe deer [ 65 ].…”

Pathogens with potential impact on reproduction in captive and free-ranging European bison (Bison bonasus) in Poland - a serological survey

et al. 2021

Background The European bison is an endangered species, and as such it is extremely important to monitor herds for pathogens which can lead to reproductive failure. The aim of the present study was to determine the current prevalence of antibodies to pathogens known to potentially influence reproduction in European bison. Serum samples from 183 bison, originating from different parts of Poland, were tested using commercial ELISA tests for antibodies to Chlamydia spp., Coxiella burnetti, Leptospira interrogans, Neospora caninum and Toxoplasma gondii; the findings were compared between captive and main free-ranging herds, and with regard to the influence of demographic factors such as age and sex. The prevalence of seropositivity was also checked with regard to location and the animal species sharing it. Results Chlamydia spp. antibodies were present in 48 out of 130 (36.9%) tested samples. Coxiella burnetii was found in one sample out of 178 (0.58%). N. caninum in 36 out of 172 (20.9%) and T. gondii in 23 out of 172 (13.4%). No sample was positive for leptospirosis. Neither sex nor age appeared to have a significant effect on the occurrence of antibodies to the identified species. The prevalence of Chlamydia spp. in the samples varied significantly according to location; however, similar frequency ranges were observed between free ranging and captive herds. In contrast, antibodies to N. caninum were more common in free-ranging herds than captive herds, with the highest frequency observed in the Bieszczady Mountains. Conclusions Chlamydia spp., N. caninum and T. gondii might have a similar impact on the reproductive potential of European bison as they have on cattle. The high occurrence of antibodies to N. caninum in bison from the Bieszczady Mountains may be associated with the relatively high density of the wolf population in the area.
