Highly toxic sulfur-containing gases have been pathogenetically implicated in ulcerative colitis. Utilizing a rat model, we studied the production and elimination of sulfur-containing gases within the unperturbed colon. The major sulfur-containing gases were hydrogen sulfide (H2S), methanethiol, and dimethyl sulfide with cecal accumulation rates of 2.6, 0.096, and 0.046 μl/min, respectively. Th...

Subulura brumpti infection was observed in Japanese quails and caused heavy production loss up to 10%. Gross lesions were confined to caecum of the affected birds. Pathological changes suggestive of acute cecal hemorrhagic enteritis were recorded. Closer observation of the cecal loop revealed wavy movement with thousands of tiny worms. Based on morphometry, the worms were identified as S. brump...

a 57-year-old male with history of prostatectomy, cyctectomy, cecal urinary diversion for invasive prostate cancer and with a recent rise in psa level, was referred for bone scintigraphy to rule out osseous metastatic disease. an interesting finding was abnormal tracer accumulation throughout the large bowel, which was proved to be due to urinary diversion.

O computed tomography there was extensive soft-tissue swelling of the cecum with a calcified fecalith (Fig. 2, arrow), which suggested diverticulitis. The patient was treated conservatively with antibiotics, and a few days later underwent a water-soluble contrast enema examination to exclude malignant disease of the cecum. This examination revealed a solitary cecal diverticulum with no evidence...

The objective of this article was to report a case of cecal diverticulitis and point out the differential diagnosis of acute appendicitis. The clinical manifestations of these pathological conditions are similar, and the accurate diagnosis of cecal diverticulitis before the surgery is difficult. Therefore, most diagnoses are made during the surgery. Moreover, cecal diverticulum is uncommon in w...

BACKGROUND Campylobacter jejuni causes enterocolitis in humans, but does not incite disease in asymptomatic carrier animals. To survive in the intestine, C. jejuni must successfully compete with the microbiota and overcome the host immune defense. Campylobacter jejuni colonization success varies considerably amongst individual mice, and we examined the degree to which the intestinal microbiota ...

An observational study was conducted to estimate prevalence and risk factors for carcass contamination by Salmonella and Campylobacter spp. in 60 lots of turkey slaughtered over 10 months in the province of Quebec, Canada. Carcass contamination was evaluated by the carcass rinse technique for about 30 birds per lot. Exposure to potential risk factors was evaluated with questionnaires, meteorolo...

Mycobacterium avium subspecies paratuberculosis (MAP) the causative agent of paratuberculosis, produces a chronic granulomatous inflammation of the gastrointestinal tract of ruminants. It has been recently suggested that MAP infection may be associated with dysbiosis of intestinal microbiota in ruminants. Since diet is one of the key factors affecting the balance of microbial populations in the...

Background: Colonoscopy is a well-established endoscopic procedure widely used for screening, diagnosis, and treatment. the examination of large bowel distal part small bowel, using some techniques that allow more frequent cecal intubation, quicker time to cecum, or less pain. One obstacle must be overcome during this looping colonoscope shaft. Objective: The aim work evaluate use simple elasti...

This study aimed to examine the mechanism for differential effects of low- (LPPS) and high-phosphorus (HPPS) potato starches and high-amylose cornstarch (HACS) on rat cecal fermentation, the n-butyrate proportion in particular. In ileorectostomized rats, the in vivo resistant starch (RS) contents were determined to be 66% (LPPS), 66% (HPPS) and 36% (HACS), but the carbohydrate/nitrogen (C/N) ra...
