Enteric bacterial infections in poultry pose a threat to intestinal health and can contribute to poor feed efficiency and livability of a flock. A variety of enteric bacterial diseases are recognized in poultry. Three of these bacterial diseases, necrotic enteritis, ulcerative enteritis, and spirochetosis, primarily infect the intestine, whereas other bacterial diseases, such as salmonellosis, ...

Lupus enteritis and lupus cystitis are relatively rare manifestations of systemic lupus erythematosus. Some patients develop severe complications such as bowel perforation, infarction, obstruction, or irreversible bladder dysfunction. Early diagnosis is critical for management of lupus enteritis and cystitis. We report a 48-year-old Japanese man who presented with initial manifestations of abdo...

Ulcerative colitis (UC)-associated pan-enteritis is a newly identified clinical entity that occurs almost exclusively after colectomy. Characterized by diffuse small bowel mucosal inflammation not compatible with Crohn's disease, the optimal treatment modality for this condition is unknown. Tacrolimus is a potent calcineurin inhibitor that has been successfully used in the treatment of UC. We d...

Necrotic enteritis toxin B (NetB) is a β-pore-forming toxin produced by Clostridium perfringens and has been identified as a key virulence factor in the pathogenesis of avian necrotic enteritis, a disease causing significant economic damage to the poultry industry worldwide. In this study, site-directed mutagenesis was used to identify amino acids that play a role in NetB oligomerisation and po...

We describe a case of systemic lupus erythematosus (SLE) with enteritis and peritonitis who later developed pneumatosis cystoides intestinalis (PCI). A 35-year-old woman with SLE relapsed with enteritis and peritonitis. Prednisolone (PSL) effectively improved her symptoms. However, 6 weeks later, she developed PCI. Tapering of PSL, administration of intravenous cyclophosphamide, prokinetic agen...

Eosinophilic enteritis is a rather rare condition that can manifest anywhere from esophagus to rectum. Its description in the literature is sparse, but associations have been made with collagen vascular disease, malignancy, food allergy, parasitic or viral infections, inflammatory bowel disease, and drug sensitivity. We present the case of a 41-year-old male diagnosed with ulcerative colitis wh...

Ulcerative colitis (UC) is a form of inflammatory bowel disease that typically involves the colorectum; it has been reported that a certain proportion of patients with UC also develop ileitis, leading to ileal perforation in very extreme cases. We report a 66-year-old male with UC who presented with ileal perforation eight days after proctocolectomy. Although this situation is very rare, differ...

ABSTRACT: This study assessed microscopic morphology of protozoan and metazoan parasites, as well parasite-associated histopathologic changes in five Brazilian free-ranging armadillos. Three armadillos had intra sarcolemmal cysts Sarcocystis sp. skeletal muscles without changes. One Dasypus novemcinctus was found parasitized with a nematode morphologically compatible an oxyurid the small intest...
