Consumption or handling of improperly processed or cooked pork is considered one of the top sources for foodborne salmonellosis, a common cause of intestinal disease worldwide. Asymptomatic carrier pigs may contaminate pork at slaughtering; therefore, pre-harvest reduction of Salmonella load can contribute to reduce public health risk. Multiple studies have evaluated the impact of vaccination on controlling Salmonella in swine farms, but results are highly variable due to the heterogeneity in vaccines and vaccination protocols...

Mechanisms governing the timing of puberty in pigs are poorly understood. A genome-wide association study for age at first estrus in pigs identified candidate genes including neuropeptide FF receptor 2 (NPFFR2), which is a putative receptor for RFamide-related peptides (RFRP). RFRP has been shown to negatively regulate secretion of reproductive hormones from hypothalamic and pituitary tissue of pigs in culture. Here, the porcine NPFFR2 gene was further screened and four potentially functional variants were identified to be associated with age at first estrus in pigs (1,288 gilts)...

Absolute uterine factor infertility, or the absence of a functional uterus, has a prevalence of 3%-5% in the general population. Despite the great strides being made in reproductive medicine, patients diagnosed with absolute uterine factor infertility remain untreatable. The only available solution has been gestational surrogacy, but recently the Brannström group presented a viable alternative by reporting the first successful live birth after uterus transplantation. Similar to other transplantations, this approach has inherent limitations such as the paucity of donor organs and the need for long-term immunosuppression...

The objective of this research was to investigate the effect of silver nanoparticles (AgNPs), free or conjugated with monoclonal antibody and mediated by Q-switched Nd:YAG laser on five dermatophytes. The laser was applied for 45 s at 532 nm and 0.8 J/cm2. The application of AgNPs combined with laser caused an increase in fungal susceptibility compared to application of AgNPs alone. The MIC50 and MIC100 recorded 3 and 9 μg/ml in the case of E. floccosum (the most susceptible species), 10 and 19 μg/ml for T...

Superficial fungal infections are a major epidemiological issue with increasing prevalence and are a common global problem. This article describes experimental therapy of superficial fungal skin infection using low-temperature plasma. Groups of guinea pigs were artificially infected with Trichophyton mentagrophytes SK 3286 dermatophyte and treated with plasma produced by a DC cometary discharge with an inserted grid. The course of infection was a week shorter and milder in animals treated by plasma than that in nontreated animals, the significant lowering of dermatophytic germs also occurred in the treated group...

Rotaviruses (RVs) are a major cause of acute viral gastroenteritis in young animals and children worldwide. Immunocompetent adults of different species become resistant to clinical disease due to post-infection immunity, immune system maturation and gut physiological changes. Of the 9 RV genogroups (A-I), RV A, B, and C (RVA, RVB, and RVC, respectively) are associated with diarrhea in piglets. Although discovered decades ago, porcine genogroup E RVs (RVE) are uncommon and their pathogenesis is not studied well...

In previous experimental studies on heroin metabolites excretion in urine, the first sample was often collected a few hours after intake. In forensic cases, it is sometimes questioned if a positive urine result is expected e.g., 30 min after intake. The aim of this study was to investigate urinary excretion of heroin metabolites (morphine, 6-monoacetylmorphine (6-MAM) and morphine-3-glucuronide (M3G)) every 30 min until 330 min after injection of a 20 mg heroin dose in six pigs. Samples were analyzed using a previously published, fully validated liquid chromatography-tandem mass spectrometry method...

There are over 150 known human proteins which are tethered to the cell surface via glycosylphosphatidylinositol (GPI) anchors. These proteins play a variety of important roles in development, and particularly in neurogenesis. Not surprisingly, mutations in the GPI anchor biosynthesis and remodeling pathway cause a number of developmental disorders. This group of conditions has been termed inherited GPI deficiencies (IGDs), a subgroup of congenital disorders of glycosylation; they present with variable phenotypes, often including seizures, hypotonia and intellectual disability...

Auditory-evoked potentials are classically defined as the summations of synchronous firing along the auditory neuraxis. Converging evidence supports a model whereby timing jitter in neural coding compromises listening and causes variable scalp-recorded potentials. Yet the intrinsic noise of human scalp recordings precludes a full understanding of the biological origins of individual differences in listening skills. To delineate the mechanisms contributing to these phenomena, in vivo extracellular activity was recorded from inferior colliculus in guinea pigs to speech in quiet and noise...

BACKGROUND Flow-diverting stent (FDS) has been suggested as an effective intracranial aneurysm treatment. However, the effects of FDS on collateral branches of an aneurysm parent artery still remain unknown. Thus, the present study aimed to comprehensively evaluate the effects of placing a FDS in the intracranial collateral artery, using a miniature pig animal model. MATERIAL AND METHODS Ten healthy miniature pigs were included in the study: one pig was reserved as a control and the remaining nine pigs were placed in three experimental groups: FDS (i...

Foot and mouth disease (FMD) is a highly contagious disease of cloven-hoofed animals, including cattle, pigs, sheep, goats, and certain wildlife species. The disease can cause massive economic losses when introduced into countries that were free from the infection, generating negative effects due to reduced animal productivity and restrictions on international livestock trade. Following 15 years of FMD absence, Tunisia and Algeria experienced an incursion of the disease in 2014. The epidemiological situation and disease control measures in operation for FMD in the North African region are not homogeneous...

Leptospirosis is a common infection in domestic animals. The microscopic agglutination test (MAT) is used for serological diagnosis. From 1988 to 2007, the Leptospira Medical and Molecular Bacteriology Laboratory at the Nantes National College of Veterinary Medicine, Food Science and Engineering used the MAT to test serum samples from more than 40,000 cattle, 40,000 pigs, 20,000 horses and 9,500 dogs. Five Leptospira serogroups were prominent, with specific variations within the four animal species: Icterohaemorrhagiae, Australis, Sejroë, Grippotyphosa and Autumnalis...

While surgical site preparation has been extensively studied, there is little information about resistance of skin microbiota in the biofilm form to antimicrobial decontamination, and there are no quantitative models to study how biofilm might be transferred into sterile tissue/implant materials during injections for joint spine and tendon, aspiration biopsies and dermal fillers (DF). In this work, we develop two in vitro models to simulate the process of skin preparation and DF injection using pig skin and SimSkin (silicone) materials, respectively...

Classical swine fever virus (CSFV) is the causative agent of classical swine fever (CSF), which poses a serious threat to the global pig industry. Interferons (IFNs) and IFN-stimulated genes (ISGs) play a key role in host antiviral defense. We have previously screened the porcine 2' -5' -oligoadenylate synthase-like protein (pOASL) as a potential anti-CSFV ISG using a reporter CSFV. This study aimed to clarify the underlying antiviral mechanism of pOASL against CSFV. We confirmed that CSFV replication was significantly suppressed in lentivirus-delivered, pOASL-overexpressing PK-15 cells, whereas silencing the expression of endogenous pOASL by small interfering RNAs markedly enhanced CSFV growth...
