Background: Inflammatory bowel disease (IBD), of which Crohn’s disease (CD) and ulcerative colitis (UC) are the two main clinicopathological subtypes, is a group of digestive system diseases of unknown etiology. Risk factors for IBD are environmental factors, genetics, and immune system agents. Mycobacterium avium subspecies paratuberculosis (MAP) is one of the most important infectious factors...

blastocystis hominis is a protozoan parasite which mainly found in human fecal samples both from symptomatic patients and asymptomatic population in developing countries. in this study we reported a patient referred to gi clinic with abdominal pain, nausea, vomiting, fever for 2 or 3 days and passed watery stools because of blastocystis sp. subtype 2 infection.

inflammatory bowel disease (ibd) is a chronic inflammatory disease affecting the gastrointestinal tract and includes ulcerative colitis and crohn’s disease. during last decades, the incidence of ibd   has increased, both in children as well as in adults (1–3). while the precise etiology of ibd is unknown, inflammatory bowel disease occure due to an abnormal immune response to luminal antigens i...

Inflammatory bowel diseases (IBD) including most important forms; Crohn’s disease (CD) and ulcerative colitis (UC); are chronic diseases affecting the gastrointestinal tract with unclear etiology and pathology. The role of gut microbiota has recently been considered as major a factor, since altered microbiome or "dysbiosis" is a key player in the protracted course of inflammation in IBD. Howeve...

Infectious bursal disease (IBD), also known as Gumboro disease, is a globally well-known disease with a significant socio-economic effect. For control of IBD, several commercial egg- and cell-based vaccines are prepared. The cell-based IBD vaccines are significantly cost-effective; however, it is essential to confirm their safety and efficacy. The main cell line used to product the cell-based I...

Background: Inflammatory bowel disease (IBD) is a chronic disease with a relapsing course of inflammation in the digestive system. Endoscopy and histopathology are the golden standard methods for detection and assessment of IBD. A distinct increase of fecal calprotectin level can be a useful marker for the diagnosis of IBD. The aim of this study was to evaluate the fecal calprotectin level in p...

background inflammatory bowel disease (ibd) is a chronic, relapsing, inflammatory disorder of the gastrointestinal tract that includes two entities, crohn`s disease (cd) and ulcerative colitis (uc). as with other complex diseases, both genetic susceptibility and environmental factors play role in the pathogenesis of these diseases. the tumor necrosis factor α (tnf-α) gene is located in the ibd3...

Background/Aims: Inflammatory bowel disease (IBD) is a chronic disease of the gastrointestinal tract, whose etiologies are still unknown. This study was performed to evaluate the humoral immune response in terms of B cell functions in selected IBD patients. Methods: Eighteen pediatric patients with IBD, including 12 cases of ulcerative colitis (UC) and six with Crohn disease (CD), were enrolled...
