This international case control study was conducted in 14 centers in 9 countries to investigate factors in childhood which may have a bearing on the etiology or pathogenesis of ulcerative colitis (UC) and Crohn's disease (CD). 197 patients with UC and 302 with CD (499 with inflammatory bowel disease (IBD] whose disease started before age 20 years and whose age at time of study was less than 25 years were investigated, with two age- and sex-matched controls for each patient. All subjects were studied with uniform questionnaires. Eczema was found significantly more frequently in patients with CD (p less than 0.005) and in their fathers (p less than 0.025), mothers (p less than 0.002), and siblings (p less than 0.01) as compared with their respective controls. IBD was significantly more frequent in parents, siblings, cousins, grandparents, and uncles of patients than in their respective controls. The fathers of patients with UC had significantly more major gastrointestinal and cardiovascular diseases at the time of the patient's birth than the fathers of controls. In North America mothers of patients with UC and CD took vitamin, mineral, and iron preparations during pregnancy significantly less frequently than mothers of controls. Patients with CD and UC consumed a lower residue diet than controls. Recurrent respiratory infections were more frequent in patients with UC and CD (p less than 0.001); it is uncertain whether this preceded disease. Hospitalization for respiratory diseases was more frequent in patients than controls, and the use of antibiotics more frequent in patients with CD. Smallpox vaccination was less frequent (p less than 0.05) in patients with CD, and chickenpox infection was less common in patients with UC (p less than 0.01). No significant differences were found between patients and controls in relation to various human and non-human contacts during childhood. Number of siblings, being an only child, and birth order did not differ markedly between patients and controls, and we could not confirm the 'sheltered child' hypothesis in IBD. The parents of controls were slightly better educated and their social class tended to be higher than those of parents of patients. There were significant associations between some of the main factors investigated in this study. No significant differences were found between patients and controls in the frequency of breast feeding, cereal consumption, sugar added to milk in infancy, gastroenteritis in childhood, major stressful life events, and many other factors.(ABSTRACT TRUNCATED AT 400 WORDS)

A growing number of Campylobacter species other than C. jejuni and C. coli have been recognized as emerging human and animal pathogens. Although C. jejuni continues to be the leading cause of bacterial gastroenteritis in humans worldwide, advances in molecular biology and development of innovative culture methodologies have led to the detection and isolation of a range of under-recognized and nutritionally fastidious Campylobacter spp., including C. concisus, C. upsaliensis and C. ureolyticus. These emerging Campylobacter spp. have been associated with a range of gastrointestinal diseases, particularly gastroenteritis, IBD and periodontitis. In some instances, infection of the gastrointestinal tract by these bacteria can progress to life-threatening extragastrointestinal diseases. Studies have shown that several emerging Campylobacter spp. have the ability to attach to and invade human intestinal epithelial cells and macrophages, damage intestinal barrier integrity, secrete toxins and strategically evade host immune responses. Members of the Campylobacter genus naturally colonize a wide range of hosts (including pets, farm animals and wild animals) and are frequently found in contaminated food products, which indicates that these bacteria are at risk of zoonotic transmission to humans. This Review presents the latest information on the role and clinical importance of emerging Campylobacter spp. in gastrointestinal health and disease.

Dogs and cats have been cohabiting with us for thousands of years. They are the major human companions. Today, dogs and cats live in urban areas. Cats and most dogs are on high carbohydrate diets and face similar life-style challenges as the human beings. The health and well-being of companion animals, just as their owners, depends on the gut microbes. Providing a proper care and nutritionally balanced diet to companion animals is recognised as a part of our responsibility to maintain the health and well being of our pet. However, as microbiota differences may facilitate exposure to pathogens and harmful environmental influences, it is prudent to search for novel tools to protect dogs and cats and at the same time the human owners from pathogens. Specific probiotic strains and/or their defined combinations may be useful in the canine and feline nutrition, therapy, and care. Probiotic supplementations have been successful in the prevention and treatment of acute gastroenteritis, treatment of IBD, and prevention of allergy in companion animals. New challenges for probiotic applications include maintenance of obesity and overweight, urogenital tract infections, Helicobacter gastritis and parasitic infections. The probiotics of human origin appear to be among the new promising tools for the maintenance of pets' health. However, the host-derived microorganisms might be the most appropriate probiotic source. Therefore, more controlled trials are needed to characterise new and safe probiotic preparations with an impact on general health and well being as well as health maintenance in dogs and cats.

During the last years, the importance of a well equilibrated intestinal microbiota (eubiosis) has become more and more obvious in human health. Dysbiosis is now a well-recognized feature associated with IBD (inflammatory bowel disease). Rupture of the normal microbiota can occur through different mechanisms: (1) by a typical Western diet rich in fat and low in fiber, (2) by an acute disruption of the microbiota (by an acute gastroenteritis or by intake of antibiotics) or (3) by a combination of event in early childhood avoiding the establishment of eubiosis (the hygiene hypothesis). Risk factors for IBD are stated for each disruption mechanism. Dysbiosis can also induce colonization by several pathobionts able to aggravate inflammation. Among the potential candidates in IBD, most attention has been paid on AIEC during the last years.
