Vaccination is an important approach for the control of avian viral diseases. The aim of this study was to evaluate the immune-potentiating effect of oral administration of Inonotus obliquus fermentation products (IOFP) at vaccination in chickens. In total, 120 one-day-old specific-pathogen-free chickens were randomly assigned to six groups: groups 1 to 3 were vaccinated with Newcastle disease virus (NDV) LaSota live vaccine via intranasal and eye-dropped route at seven days of age, and boosted two weeks later...

Streptococcus pyogenes (Group A Streptococcus, GAS) and Streptococcus agalactiae (Group B Streptococcus, GBS) are common pathogens that threaten public health. In this study, a double recombinase polymerase (RPA) amplification assay was developed to rapidly detect these pathogens. Specificity tests revealed that the GAS and GBS strains were positive for speB and SIP genes, respectively. In clinical samples, the double assay performed similarly to the traditional biochemical method. The limits of detection were both ≤100 copies per reaction...

Theiler's murine encephalomyelitis virus (TMEV) is one of the most common viral pathogens that circulate widely in captive mouse colonies. A molecular biology detection method would be a useful tool to use in an integrated program to monitor and prevent TMEV infection and transmission. Thus, a reverse transcription recombinase polymerase amplification (RT-RPA) assay was developed to detect TMEV infection. The sensitivity of the RT-RPA assay approached 8 copies per reaction, which is equivalent to the sensitivity of RT-qPCR reactions...

TTR amyloidosis (ATTR) is a fatal condition caused by extracellular deposits of misfolded transthyretin. Patients often present with cardiac disease, but manifestations may also involve other organs including the peripheral nervous system. ATTR is considered familial when heterozygous mutations in the TTR gene are present (ATTRmutant or ATTRm), or acquired when no TTR aberrations are detected (ATTRwildtype or ATTRwt). We hypothesized that TTR copy number variants (CNVs), which would escape the standard diagnostic approaches, contribute to ATTR-related phenotypes, and developed a multiplex ligation-dependent probe amplification-based (MLPA-based), TTR-specific copy number screening tool...

Bovine respirovirus 3 also known as Bovine parainfluenza virus type 3 (BPIV3) is one of the most important viral respiratory agents of both young and adult cattle. Rapid diagnosis could contribute greatly in containing epidemics and thus avoid economic losses. However, the lack of robust isothermal visual method poses difficulty. In this study, a novel isothermal assay for detecting BPIV3 was established. The method includes a lateral flow dipstick (LFD) assay combined with reverse transcription recombinase polymerase amplification (RT-RPA)...

In this paper, we report on the development of a real time high-resolution melting (HRM) PCR assay for detection and differentiation among sheep pox virus (SPPV), goat pox virus (GTPV), field isolates and vaccine strains of lumpy skin disease virus (LSDV) based on high-resolution melting curve analysis of their target PCR amplicons. A 111 bp region of LSDV010 ORF, which harbors unique genetic differences for each of these viral species, was selected as the PCR target in this study. During the validation of this assay using DNA from clinical isolates originated from naturally infected animals from the different geographic locations and reference strains, the obtained PCR amplicons demonstrated that the melting temperature picks were specific for each tested viral species, i...

Overo lethal white foal syndrome (OLWFS) is a genetic disorder caused by a dinucleotide mutation in the endothelin receptor type B (EDNRB) gene leading to the death of affected foals shortly after birth. The use of rapid and reliable genetic testing is imperative for the early diagnosis of the mutation avoiding, therefore, either additional suffering or the production of affected animals. In the present study, we developed and validated a high-resolution melting (HRM) genotyping assay to detect the OLWFS causative mutation, and we also determined the frequency of heterozygotes among American Paint horses in Brazil...

C5a is an important pro-inflammatory peptide involved in complement activation, membrane attack complex formation, immune cell chemotaxis, and allergic responses. Osteoarthritis is a disease characterized by degenerative changes in articular cartilage. It has recently been found that inflammatory responses play an important role in the pathogenesis of osteoarthritis and also in rheumatoid arthritis, where dysfunctional synoviocytes are involved. We performed a series of studies to verify our hypothesis that inhibition of C5a would prevent IL-1β-induced alternations in rat synoviocytes...

BACKGROUND: Depo-medroxyprogesterone acetate (DMPA) is an injectable progestin contraceptive that provides a highly effective reduction of pelvic pain in women with endometriosis. Despite its wide use to treat pain associated with endometriosis, its precise mechanisms of action remain unclear. The aims of this study were to investigate the differential expressions of estrogen receptors (ERs), and progesterone receptors (PRs) in endometria and ovarian endometrioma cyst walls of women with endometriosis with and without DMPA treatment...

Bovine mastitis is an inflammation response of the mammary gland tissues caused mainly by pathogenic bacteria in cows. Previous studies showed that bta-miR-15a and bta-miR-16a modulate immunity and inflammation responses. In this study, we investigated the expression pattern and tissue localization of bta-miR-15a and bta-miR-16a. The expression levels of bta-miR-15a and bta-miR-16a were significantly upregulated in mammary tissues and blood neutrophils of mastitis-infected cows, compared with those of healthy cows (P < 0...

Coupling propidium monoazide (PMA) with quantitative PCR (PMA-qPCR) has been successfully applied to specific detection and quantification of viable cells in various samples. The optimal PMA treatment condition is usually determined through qPCR. However, it is a tedious, time consuming and costly process including DNA extraction and qPCR. To overcome this problem, a flow cytometry-based (FCM-based) method was first proposed in this study to replace qPCR for screening of the optimal PMA treatment condition for Helicobacter pylori, since the pure culture treated with PMA was actually a single cell suspension with fluorescent dye...

Ronald J A Wanders
Peroxisomes catalyze a number of essential metabolic functions of which fatty acid alpha- and beta-oxidation, ether phospholipid biosynthesis, glyoxylate detoxification and bile acid synthesis are the most important. The key role of peroxisomes in humans is exemplified by the existence of a group of peroxisomal disorders, caused by mutations in > 30 different genes which code for proteins with a role in either peroxisome biogenesis or one of the metabolic pathways in peroxisomes. Technological advances in laboratory methods at the metabolite-, enzyme-, and molecular level have not only allowed the identification of new peroxisomal disorders but also new phenotypes associated with already identified genetic defects thus extending the clinical spectrum...

Ruthellen H Anderson, Kevin R Francis
Rare diseases, in totality, affect a significant proportion of the population and represent an unmet medical need facing the scientific community. However, the treatment of individuals affected by rare diseases is hampered by poorly understood mechanisms preventing the development of viable therapeutics. The discovery and application of cellular reprogramming to create novel induced pluripotent stem cell models of rare diseases has revolutionized the rare disease community. Through developmental and functional analysis of differentiated cell types, these stem cell models carrying patient-specific mutations have become an invaluable tool for rare disease research...
