The objective of the study was to determine selenium content in selected organs (liver, kidney) of wild boars from different regions of Poland. Materials for the study were obtained from 28 sites located in 16 provinces of Poland. Selenium concentrations in organs were determined using spectrofluorometric methods after wet mineralization in HNO3 and HClO4 mixture. Mean selenium concentrations in the investigated wild boars from Poland were 0.230 μg/g wet weight in the liver and 1.327 μg/g w.w. in the kidneys...

The cation channel of sperm (CatSper) comprises four transmembrane subunits specifically expressed in human, equine, murine and ovine spermatozoa, apparently implicated in capacitation, hyperactivation and acrosome exocytosis. Western blotting and immunocytochemistry showed hereby that CatSper subunits are also present in boar spermatozoa, primarily over the sperm neck, tail and cytoplasmic droplets; albeit CatSper -1 presented in addition some distribution over the membrane of the acrosome and CatSper -2 and -4 over the membrane of the post-acrosome...

The domestic animals descend from various wild ancestors. Thus, for example, of the wolf, the dog (15  000 BC), of the Bezoar goat the goat (10  000 BC), of the Asian mouflon the sheep (10  000 BC), of the wild boar the pig (8000 BC) and of the aurochs the cattle (7000 BC). Domestication has dramatically changed our culture and led to a great diversity of animal breeds. This is a unique cultural and historical treasure, which we have to preserve for future generations. The zoological park Arc Warder is Europe's largest center for rare and endangered domestic animal breeds...

An HIV-infected patient was diagnosed with acute hepatitis E infection in our hospital. An epidemiological inquiry was performed to collect demographic, food and animal exposure variables in order to identify the potential route of transmission. The patient reported that his family traditionally hunted wild boar for food. All family members were analysed for hepatitis E virus infection. Additionally, route of transmission by wild boar meat consumption and prevalence of HEV infection among wild boar from the same hunting area were investigated...

To achieve a standardized number of spermatozoa in the final AI dose, varying amounts of extender fluid with a fixed concentration of antimicrobial substances are currently added to boar ejaculates. This practice ignores the different degrees of dilution of the antimicrobials in the end product. In calculating the final concentration of gentamicin in AI doses from 27,538 processed boar ejaculates, we demonstrated varying gentamicin concentrations in the resultant extended boar semen samples. The median concentration was 220...

BACKGROUND: Cryptosporidium spp., Giardia duodenalis and Enterocytozoon bieneusi are the main causal pathogens of gastrointestinal disease. However, there are limited reports about the prevalence of these organisms in captive Eurasian wild boars worldwide. Therefore, we examined the occurrence and identified the species/assemblages/genotypes of these pathogens in captive Eurasian wild boars, and estimated the zoonotic potential. FINDINGS: Of 357 fecal samples collected from captive Eurasian wild boars in China, 155 (43...

BACKGROUND: Non-invasive sampling techniques based on the analysis of oral fluid specimen have gained substantial importance in the field of swine herd management. Methodological advances have a focus on endemic viral diseases in commercial pig production. More recently, these approaches have been adapted to non-invasive sampling of wild boar for transboundary animal disease detection for which these effective population level sampling methods have not been available. In this study, a rope-in-a-bait based oral fluid sampling technique was tested to detect classical swine fever virus nucleic acid shedding from experimentally infected domestic pigs...

The AA requirements of reproducing females are likely influenced by genetics, number of embryos and fetuses, and their nutritional needs during development. Hence, it is important to determine the change in AA concentration during development. Fetuses from a total of 26 second-parity sows were used to determine their AA composition at various stages of pregnancy. Yorkshire × Landrace sows were bred to Duroc boars and killed at 45, 62, 80, and 100 d of gestation, and fetal weights were determined. The pigs from 6 litters were killed prior to nursing the sow...

The use of antimicrobial peptides (AMP) has become one of the most promising alternatives to the use of antibiotics (Abs) in semen extender's formulation to overcome the increasing bacterial resistance to antibiotics. However, AMP may impair boar sperm quality, so that their deleterious effects might be higher than their effectiveness against bacteria. Thus, the aim of this study was to determine whether three different AMP, the proline-arginine-rich antimicrobial peptide PR-39 (PR-39), and the porcine myeloid antimicrobial peptides 36 (PMAP-36) and 37 (PMAP-37) had any effect upon boar sperm quality and bacterial growth...

Domestic and wild pigs, as intermediate hosts, can harbor tissue cysts of three Sarcocystis species namely S. miescheriana, S. suihominis and S. porcifelis. Out of them, S. suihominis is zoonotic. Romania is a country with high consumption of raw and/or undercooked traditional pork products. This fact may greatly favor the acquiring of the zoonotic Sarcocystis infections by humans, as definitive host. Based on this consideration and in order to investigate the occurrence and public health significance of Sarcocystis spp...

The increasing number of antimicrobial resistant Enterobacteriaceae both in veterinary and human medicine, the dissemination of these bacteria in several environments and their possible repercussions on human health is causing concern. Game meat is usually seen as free of antimicrobial resistant bacteria. The objective of this study was to evaluate the current antimicrobial susceptibility status in generic Escherichia coli isolated from packed frozen game meat from a game handling establishment in Germany. A total of 229 E...

The aroma profile of porcine fat from tainted boars, female pigs and castrated male pigs was investigated by application of comparative aroma extract dilution analysis (cAEDA) on a SAFE distillate of volatiles prepared from porcine back fat samples. The AEDA resulted in a total of 16 aroma active compounds for boar fat with flavor dilution (FD) factors ranging from 2 to 2048, while 12 aroma active compounds were found in fat of female pigs and 14 in fat of castrated male pigs, both with FD factors ranging from 2 to 32...

Tannins have long been considered 'anti-nutritional' factors in monogastric nutrition, shown to reduce feed intake and palatability. However, recent studies revealed that compared with condensed tannins, hydrolysable tannins (HT) appear to have far less impact on growth performance, but may be inhibitory to the total activity of caecal bacteria. This in turn could reduce microbial synthesis of skatole and indole in the hindgut of entire male pigs (EM). Thus, the objective of this study was to determine the impact of a group of dietary HT on growth performance, carcass traits and boar taint compounds of group housed EM...

Since their commercialization, vaccines against Porcine circovirus type 2 (PCV2) have been the cornerstone control strategy. Nevertheless, the periodic emergence of new genotype waves and the recent reports of vaccine failure outbreaks have raised the question if widespread vaccination strategies could have driven viral evolution and affected different genotype fitness. To investigate this issue an in-deep analysis, based on a bioinformatics and biostatistics approach, has been implemented. ORF2 sequences from vaccinated and non-vaccinated populations (i...

Oxidative metabolism of estrogens is an important feature in liver and some non-hepatic tissues. In initial studies on estrogen metabolism in tissues from the reproductive tract of the stallion, where testicular estrogen secretion is remarkably high, a prominent radiolabeled product from [(3)H]-estrone (E1) was noted on chromatography; it had a retention time (Rt) between 17β-estradiol (E2) and E1. Unexpectedly, when non-radiolabeled E1 was the substrate no UV absorption at 280nm was seen at the Rt for the [(3)H]-labeled product-suggesting a non-aromatic ring A...

The present study compares the sperm quality of boar seminal doses artificially inoculated with Escherichia coli and Clostridium perfringens, and maintained in liquid storage at 15°C for a 9-day period. Seminal doses from 10 sexually mature Piétrain boars were diluted in a Beltsville Thawing Solution (BTS)-based extender and infected either with E. coli or C. perfringens, with bacterial loads ranging from 10(1) to 10(7)cfumL(-1). During storage, the changes in sperm quality were determined by assessing pH, sperm viability, sperm motiliy, sperm morphology, sperm agglutination degree, and sperm-bacteria interaction...

To determine animal hepatitis E virus (HEV) reservoirs, we analyzed serologic and molecular markers of HEV infection among wild animals in Germany. We detected HEV genotype 3 strains in inner organs and muscle tissues of a high percentage of wild boars and a lower percentage of deer, indicating a risk for foodborne infection of humans.

Few sex-autosome chromosome abnormalities have been documented in domestic animal species. In humans, Y-autosome chromosome abnormalities may occur at a rate of 1/2,000 live births, whereas in the domestic pig only 2 Y-autosome reciprocal translocations have been previously described. During a routine cytogenetic screening of young boars, we identified a new Y-autosome translocation carrier, which after puberty showed semen devoid of sperm and testicular hypoplasia with spermatogenesis arrest. Whole chromosome painting by FISH analysis corroborated the reciprocal nature of the chromosomal exchanges between the Y chromosome and SSC13...
