Cavitating mesenteric lymph node syndrome (CMLNS) is a rare and poorly understood complication of coeliac disease (CD), with only 37 cases reported in the literature. CD is an immune-mediated enteropathy, with alterations seen in the small bowel architecture on exposure to ingested gluten. Those who fail to respond to a strict gluten-free diet are termed to have refractory coeliac disease (RCD)...

Lymph nodes (mandibular, mesenteric, mediastinal, and subiliac; n = 68) and fecal (n = 68) and hide (n = 35) samples were collected from beef carcasses harvested in an abattoir in Mexico. Samples were analyzed for Salmonella, and presumptive colonies were subjected to latex agglutination. Of the isolates recovered, a subset of 91 was characterized by serotyping, pulsed-field gel electrophoresis...

Caseous lymphadenitis caused by Corynebacterium pseudotuberculosis is mainly a disease of sheep and goats and is of zoonotic importance. The disease has rarely been recorded in cattle and mostly in its superficial form. The present communication deals with an extremely rare case of corynebacterium-induced mesenteric pseudotuberculosis in a cow calf. The gross, cytologic, histopathologic and mic...

The sandwich sign is used to describe mesenteric lymphoma in which mesenteric vessels and fat are enveloped by enlarged mesenteric lymph nodes. We present two cases of primary pleural lymphoma demonstrating the "pleural sandwich sign". Contrast-enhanced computed tomography showed conglomerated parietal pleural and extrapleural masses encasing the intercostal arteries. Histopathological examinat...

at present, most of iran is free of bovine tuberculosis (tb). the strategy of control and eradication in iran involves a tuberculation test and slaughter of reactors, a procedure transformed the present-day prevalence of tb into a sporadic occurrence. this paper describes the first report of bovine tuberculosis in a european fallow deer ( dama dama dama ) in iran. the deer was emaciated and fou...

linguatula serrata is one of the important zoonotic parasites. carnivores serve as definitive host. the larvae existed in mesenteric lymph nodes (mlns), liver, lungs, etc of intermediate herbivores. the definitive host becomes infected by ingesting viscera containing the infective nymphal stage. humans may be infected with linguatula either by ingestion of nymphs resulting in a condition called...

A 9-year-old neutered male Munchkin cat presented to our clinic with lethargy and anorexia. Abdominal ultrasonography revealed multiple enlarged mesenteric lymph nodes. Cytology immunocytochemical staining suggested large granular lymphocyte (LGL) lymphoma derived from cytotoxic T cells. Treatment nimustine (ACNU) (25 mg/m2, intravenously, every 3 weeks) resulted in long-term complete remission...

54-year female presented with a lesion on her left buttock and perineum for approximately 18 months prior to seeking evaluation. It has grown gradually over this period of time. She constipation, perineal bleeding, pain, weight loss twenty pounds. CT abdomen pelvis showed large mass in the extending into anus enlarged lymph nodes. PET intensely hypermetabolic involving anal canal, mildly FDG av...

1. Normal guinea pigs exposed to tuberculous cage mates infected intraperitoneally and with no cutaneous ulceration readily contract spontaneous tuberculosis. 2. The incidence of spontaneous tuberculosis increases with the intensity and with the duration of exposure. 3. Spontaneous tuberculosis acquired from infected cage mates has with few exceptions the characters of an infection which has en...

The homing receptors L-selectin and alpha4beta7 integrin facilitate entry of T cells into the gut-associated organized lymphoid tissues such as the mesenteric lymph nodes and Peyer patches. We studied the impact of inactivation of genes encoding these receptors on the ability of purified donor CD4+ T cells to induce acute lethal graft-versus-host disease (GVHD) associated with severe colitis in...
