Despite the importance of Bordetella avium (BA) as a respiratory pathogen of young turkeys, no infection model for the evaluation of BA-vaccine efficacy is available. The objective of this study was to evaluate the influence of route and dose of infection on the establishment of a BA-challenge model. In our first experiment, 28-day-old turkeys were either inoculated oculonasally with 10(5), 10(7) or 10(9) colony forming units (CFU) of BA per animal or exposed to BA by aerosol with 10(5)-10(8) CFU/m(3). The respiratory tract of all inoculated animals was BA-colonised, which was confirmed by choanal swabs and samples of trachea and lung, showing the highest prevalence in the aerosol inoculated group...

INTRODUCTION: Celiac disease (CD) is an autoimmune enteropathy associated with gluten ingestion. In extended families of celiac patients that live in close proximity of one another, shared genetic and environmental factors can predispose them to CD. AIM: The aim of this study was to provide evidence about the genetic and environmental factors involved in the development of CD in the extended family of a pediatric patient. METHODS: The medical history, environmental conditions, and participant weight, height, and peripheral blood samples were evaluated...

Disruptions to the gut microbiota have been associated with a variety of diseases. Understanding the underlying mechanisms that regulate the maintenance of a healthy microbiota may therefore have therapeutic implications. Secretory IgA play a unique role in immune-microbiota crosstalk by directly binding to bacteria in the gut lumen. Microbe-specific IgA responses co-develop with the assembly of the gut microbiota during infancy, and resemble those of adults by 2 years postnatally in the healthy host. We propose here that microbiota-specific IgA-producing gut plasma cells generated during infancy live for many decades and contribute to a stable microbiota community...

IgA vasculitis (IgAV) is a leukocytoclastic vasculitis and characterized by involvement of small vessels in skin, gastrointestinal system, joints, kidneys, and less frequently other organs. It is the commonest vasculitis in childhood and etiology is not completely known. Neurological manifestations of IgAV are very rare and usually seen in patients with severe hypertension or as an uncommon feature such as peripheral neuropathy. Posterior reversible encephalopathy syndrome (PRES) is a clinic-radiologic entity characterized with temporary vasogenic edema developing typically in posterior circulation of the brain and has been reported as a rare manifestation of IgAV...

Exposure to high fluorine can cause toxicity in human and animals. Currently, there are no systematic studies on effects of high fluorine on blood cellular immunity and humoral immunity in mice. We evaluated the alterations of blood cellular immunity and humoral immunity in mice by using flow cytometry and ELISA. In the cellular immunity, we found that sodium fluoride (NaF) in excess of 12 mg/Kg resulted in a significant decrease in the percentages of CD3(+), CD3(+)CD4(+), CD3(+)CD8(+) T lymphocytes in the peripheral blood...

By radiolabelling monomeric (m) and polymeric (p) IgA with technetium 99m ((99m)Tc), this study assessed IgA biodistribution and tumour-targeting potency. IgA directed against carcinoembryonic antigen (CEA), a colorectal cancer marker, was selected to involve IgA mucosal tropism. Ig was radiolabelled with (99m)Tc-tricarbonyl after derivatisation by 2-iminothiolane. (99m)Tc-IgA was evaluated by in vitro analysis. The biodistributions of radiolabelled anti-CEA mIgA, pIgA and IgG were compared in normal mice. Anti-CEA pIgA tumour uptake was studied in mice bearing the WiDr caecal orthotopic graft...

The purpose of this study was to evaluate the potential of chitosan units released during natural degradation of the polymer to activate the immune system against T. spiralis infection. High molecular weight chitosan was injected intraperitoneally into C57BL/6 mice. Flow cytometry and cytokine concentration, measured by ELISA, were used to characterize peritoneal cell populations during T. spiralis infection. The strong chemo-attractive properties of chitosan caused considerable infiltration into the peritoneal cavity of CD11b⁺ cells, with reduced expression of MHC class II, CD80, CD86, Dectin-1 or CD23 receptors in comparison to T...

BACKGROUND: The immunosuppressive drug tacrolimus has the short-term effect of reducing proteinuria in patients with immunoglobulin A nephropathy (IgAN). Our study investigated the effects on proteinuria and kidney function after discontinuation of tacrolimus. METHODS: Patients with biopsy-proven IgAN were included in the study and randomly divided into two treatment groups. There was a corresponding control group for each treatment group. The first group included patients treated with tacrolimus (Tac vs non-Tac group) and the second group included patients with a renin angiotensin system blocker (RASi vs non-RASi group)...

As the population ages, greater numbers of elderly patients will present with kidney diseases. Many kidney diseases, such as IgA nephropathy, will require kidney biopsy for diagnostic confirmation, treatment guidance and prognostication. In this paper, we review the current and expected future healthcare landscape with a focus on the ageing population, pros and cons of kidney biopsy in elderly patients, as well as treatment strategies and precautions. We also review the available data on IgA nephropathy in the elderly, including its occurrence rate based on the kidney biopsy, clinicohistopathological features, differentiation with IgA-dominant postinfectious glomerulonephritis, treatment options and outcome prediction...

Bacteriophage are structurally stable in the gastro-intestinal tract and have favorable traits of safety, stability, ease of production, and immunogenicity. These attributes make them potential candidates as oral vaccine delivery vehicles but little is known about their capacity to induce mucosal immune responses in the small intestine. Whole body imaging of mice confirmed lambda bacteriophage (LP) were distributed throughout the gastro-intestinal tract 24 h after oral delivery. In newborn calves, targeted delivery of LP within the small intestine confirmed LP were immunogenic in a dose-dependent manner and were taken up by Peyer's patches...

Human parainfluenza virus type 3 (PIV3) is a major cause of lower respiratory disease i.e. bronchitis, bronchiolitis or pneumonia, in infants and young children. Presently there is no licensed vaccine against PIV3. To produce an effective subunit vaccine, a chimeric FHN glycoprotein consisting of the N-terminal ectodomain of the fusion (F) protein linked to the haemagglutinin-neuraminidase (HN) protein without transmembrane domain, and secreted forms of the individual F and HN glycoproteins, were expressed in mammalian cells and purified...

BACKGROUND: Some iodinated radio-contrast media absorb UV light and can therefore be detected by capillary zone electrophoresis (CZE). If seen, these peaks are typically small with "quantifications" of below 5g/L. Here we describe detection of a large peak on CZE that was due to the radio-contrast agent, Omnipaque(T)(M). METHODS: Serum from a patient was analysed by CZE, and the IgG, IgA, IgM and total protein concentrations were measured. The serum sample was further analysed by gel electrophoresis and immunofixation...

A variety of laser/light-based devices have been reported to be effective for the treatment of acne, yet no long-term data on efficacy and safety have been published. A first 12-week clinical trial ("Main trial") recently demonstrated that the KLOX BioPhotonic System, an LED blue light device using photo-converter chromophores, can significantly improve moderate and severe facial acne vulgaris with an excellent safety profile. This Extension trial followed the Main trial, using the same BioPhotonic System, with the same dose and instructions for use, on patients having already completed treatment in the Main trial...

BACKGROUND: Monophasic Salmonella Typhimurium (mSTM) strains account for up to 8.6% of all human Salmonellosis cases. They have an increasing prevalence during recent years and several human cases with hospitalisation were reported. These strains are often isolated from pigs and pork - one primary source of human infection. A Salmonella Typhimurium (STM) live vaccine has been proven successful in controlling of STM infections in pigs for many years. The aim of this study was to test the immunogenicity of the vaccine in weaners during oral challenge with a virulent mSTM strain and to examine the kinetics of STM-specific IgA, IgM and IgG antibodies induced by vaccination and infection...
