Hepatitis E is an emerging viral disease in developed countries, with sporadic cases occasionally linked to the consumption of raw or undercooked pork, wild boar or deer meat. Cases due to transfusion or transplantation have also been reported. In developed countries, hepatitis E is considered a zoonosis and pig is the main reservoir. In the last few years, several studies conducted in Europe reported variable seroprevalence rates among the general population, ranging between 0.26% and 52.5%. A higher seroprevalence was described among workers who come in contact with pigs...

The Veterans Health Administration implemented a Virtual Breakthrough Series to prevent pressure ulcers. The pressure ulcer rate decreased from 1.2 to 0.9 per 1000 bed days of care (P = .017). The most common interventions were education (N = 26; 68%), improved documentation (N = 23; 61%), and the use of equipment and supplies (N = 21; 55%). In summary, this project helped improve pressure ulcer rates in the Veterans Health Administration and presents a promising model for implementing a virtual model for improvement...

A 2-period field trial was conducted to determine the effects of feeding regimen on weight gain, semen characteristics, libido, and lameness in 170- to 200-kg (period 1) and 200- to 250-kg (period 2) boars. Sixty-one Duroc boars were allotted to 1 of 3 dietary treatments and 15 g/d fish oil was also provided for each experimental boar, to maintain the n-6:n-3 intake ratio at approximately 6.1:1. The energy intakes of the 3 treatment groups were controlled by basing the feed intake on a corn-soybean meal-based diet (3...

The aim of our study was to compare different validation methods with respect to their impact on validation results and to evaluate the feasibility of genomic selection in the German Landrace population of the Bavarian herdbook. For this purpose, a sample of 337 boars and 1,676 sows was genotyped with the Illumina PorcineSNP60 BeadChip. Conventional BLUP breeding values for fertility, growth, carcass, and quality traits were deregressed and used as phenotypes in genomic BLUP. The resulting genomic breeding values were also blended with information from the full conventional breeding value estimation to include information from nongenotyped parents...

Genetic trends for male and female sexual development and components of litter size and weight at birth (LB) as well as traits related to sow lifetime productivity were estimated in a French Large White (LW) pig population using frozen semen. Two experimental groups (EXP = L77 and L98) were produced by inseminating LW sows with either stored frozen semen from 17 LW boars born in 1977 (EXP = L77) or with semen from 23 LW boars born in 1998 (EXP = L98). In each group, about 100 males were measured for testicular development and bulbo-urethral gland development, and 90 gilts were checked for puberty, among which about 50 gilts were measured for their first ovulation rate at puberty (ORP)...

Today, early weaning is more frequently applied by the modern pig breeder to obtain more litters per year. In addition, more and more European pig breeders apply a batch management system, which allows weaning to occur at fixed time points but entails that the offspring are treated at the litter level and not as individuals. Both evolutions might result in weaning lightweight piglets, which can cause, e.g., growth retardation of the offspring. Hence, the objective of this research was to improve the weaning weight of piglets of the same age by breeding with a highly conformed sire line...

In northwest Poland, 163 blood and 53 fecal samples of wild boars were collected in winter 2012/13 and 2013/14. All blood samples were tested for the presence of hepatitis E virus (HEV) ribonucleic acid (RNA) by two reverse transcription-polymerase chain reaction (RT-PCR) based methods and by anti-HEV IgG enzyme-linked immunosorbent assay (ELISA). About 17.2% of blood samples were seropositive. One-step nested RT-PCR turned out to be too insensitive (11.6% were positive). Therefore a two-step nested RT-PCR was applied where 25...

Porcine reproductive and respiratory syndrome virus (PRRSV) is highly genetically diverse; however, little is known about the molecular epidemiology of PRRSV in the boar farms of South China. In this study, 367 samples were collected from boar farms in South China in 2015. The Nsp2 hypervariable region and ORF5 gene were PCR amplified from 66 PRRSV-positive samples, followed by sequencing and analysis. The percentage of PRRSV antigen-positive samples was 17.98%; 8.72% were positive for highly pathogenic PRRSV (HP-PRRSV), and 9...

Echinococcus granulosus sensu lato (s.l.) is a zoonotic disease highly endemic in Tunisia. Canids including stray and semi-stray dogs, jackals and foxes are known as definitive hosts and a wide range of ungulates have been shown to harbour the metacestode hydatid stage and may serve as intermediate hosts. Fertile hydatid cysts of Echinococcus equinus and E. granulosus sensu stricto (s.s.) were recently molecularly identified for the first time from Tunisian donkeys. E. granulosus (s.s.) was also identified from wild boars in Tunisia...

Boar taint is an offensive odor that can occur while cooking pork or pork products and is identified in some uncastrated male pigs that have reached puberty. It is widely held that boar taint is the result of the accumulation in back-fat of two malodorous compounds: androstenone and skatole. The purpose of the present study was to assess a mass spectrometry-based metabolomics strategy to investigate the metabolic profile of urine samples from pig carcasses presenting low (untainted) and high (tainted) levels of androstenone and skatole in back fat...

Classical swine fever (CSF) can run acute, chronic, and prenatal courses in both domestic pigs and wild boar. Although chronic infections are rare events, their epidemiological impact is very high due to the long-term shedding of virus. So far, little is known about the factors that influence disease course and outcome from either the host or virus's perspective. To elucidate the viral determinants, we analyzed the role of the viral populations for the development of chronic CSF virus (CSFV) infections. Three different animal trials that had led to both chronic and acute infections were chosen for a detailed analysis by deep sequencing...

A number of emerging studies suggest that air pollutants such as hydrogen sulfide (H2S) and ammonia (NH3) may cause a decline in spermatozoa motility. The impact and underlying mechanisms are currently unknown. Boar spermatozoa (in vitro) and peripubertal male mice (in vivo) were exposed to H2S and/or NH3 to evaluate the impact on spermatozoa motility. Na2S and/or NH4Cl reduced the motility of boar spermatozoa in vitro. Na2S and/or NH4Cl disrupted multiple signaling pathways including decreasing Na(+)/K(+) ATPase activity and protein kinase B (AKT) levels, activating Adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) and phosphatase and tensin homolog deleted on chromosome ten (PTEN), and increasing reactive oxygen species (ROS) to diminish boar spermatozoa motility...

A pathological and epidemiological study on Macracanthorhynchus hirudinaceus infection on 25 wild boars Sus scrofa in southwestern Iran was done. Overall 24 helminthes (18 female and 6 male) were collected from the intestine of 13 infected wild boars. Thus, the prevalence of acanthocephalans among the 25 examined boars was 52 %. Pathological evaluation revealed damages caused by the acanthocephalans penetrated in the small intestine tissue. Helminthes caused severe necrosis with ulcer and inflammation in tunica sub mucosa layer...

BACKGROUND: Anaplasma phagocytophilum is the causative agent of tick-borne fever, a disease with high economic impact for domestic ruminants in Europe. Epidemiological cycles of this species are complex, and involve different ecotypes circulating in various host species. To date, these epidemiological cycles are poorly understood, especially in Europe, as European reservoir hosts (i.e. vertebrate hosts enabling long-term maintenance of the bacterium in the ecosystem), of the bacterium have not yet been clearly identified...

Owing to current problems in boar sperm cryopreservation, this study proposes to evaluate vitrification in spheres as an alternative cryopreservation procedure, comparing the use or not of permeable cryoprotectants and two warming methods. Extended (n = 3; r = 4) and raw (n = 5; r = 2) porcine spermatozoa were diluted in media, in the absence or presence of either 4% dimethylformamide or 4% glycerol, to a final concentration of 5 × 10(6)  spermatozoa/ml and vitrified using the spheres method. Two warming procedures were evaluated: a rapid method (30 s at 37°C) and an ultrarapid method (7 s at 75°C, followed by 30 s at 37°C)...

African swine fever (ASF) is a major pig health problem, and the causative virus is moving closer to Western European regions where pig density is high. Stopping or slowing down the spread of ASF requires mitigation strategies that are both effective and practical. Based on the elicitation of ASF expert opinion, this study identified surveillance and intervention strategies for ASF that are perceived as the most effective by providing the best combination between effectiveness and practicality. Among the 20 surveillance strategies that were identified, passive surveillance of wild boar and syndromic surveillance of pig mortality were considered to be the most effective surveillance strategies for controlling ASF virus spread...

A panel comprising 16 short tandem repeats (STRs) and a gender-specific amelogenin marker was worked out and tested for robustness in discrimination between wild and domestic swine subspecies encountered in Europe, between regional populations of wild boars and between main breeds of domestic pigs reared in Belarus. The STR dataset comprised 310 wild boars, inhabiting all administrative regions of Belarus, and 313 domestic pigs, representing three local and three cosmopolitan lines. Additionally, a total of 835 wild boars were genotyped for the presence of melanocortin 1 receptor (MC1R) alleles specific for domestic pigs...

AIM: Wild boars, Sus scrofa, are potential reservoirs of many zoonotic diseases, and there are a possibility of transmission of the zoonotic diseases from these animals to humans and also domestic animals. This study aimed to evaluate the protozoan contamination of wild boars in the Persian Gulf's coastal area (Bushehr Province), southwestern Iran. MATERIALS AND METHODS: A total of 25 crossbred boars were collected during a course of vertebrate pest control in Bushehr province, in 2013...
