Sterigmatocystin (7.75 micrograms/g of feed) and a high-propagule-density of Aspergillus versicolor were detected in feed associated with acute clinical symptoms of bloody diarrhea and death in dairy cattle. Nine isolates of A. versicolor from the feed produced 13 to 89 micrograms of sterigmatocystin per g on cracked corn and lower amounts in liquid culture. This is the first report of sterigma...

Introduction: A five-year-old year old girl developed fever of 40.3° C, vomiting, mild general abdominal pain, followed by bloody diarrhea. Description: Ultrasonography revealed a length of symmetrically thickened terminal ileum, more than 20 cm long, with walls greater than 0.5 cm containing a long narrow lumen < 1 mm wide. Conclusion: Given the difficulty of diagnosing the cause of enteritis ...

Arcobacter cryaerophilus is an emerging enteropathogen and potential zoonotic agent transmitted by food and water. In Costa Rica, this bacterium has not been associated with cases of human gastroenteritis, even though it has been isolated from farm animals, especially poultry. This paper reports the first isolation of A. cryaerophilus from a human case of bloody watery diarrhea and the virulenc...

This case highlights one of the infrequent complications of a commonly abused substance. A particular high index of suspicion of ischemic bowel is associated with cocaine abuse and should be included in the differential diagnosis of any young adult or middle-aged patient with abdominal pain and/or bloody diarrhea, particularly in the absence of other predisposing factors. To our knowledge, we r...

Ecthyma gangrenosum typically occurs in patients who are immunocompromised. It is most often associated with a Pseudomonas aeruginosa bacteremia but other pathogens can be found. We report an HIV-infected patient with disseminated nontuberculous mycobacterial infection who presented with fever, mucous bloody diarrhea and cutaneous lesions on both legs. The cutaneous lesions had ecthyma gangreno...

We report the case of an octagenerian who presented with leukocytoclastic vasculitis as the first symptom of Crohn’s disease. The patient was admitted with skin rash on the lower extremities and ankles and episodes of bloody diarrhea. Skin and colon biopsies revealed acute leukocytoclastic vasculitis and moderate Crohn’s disease, respectively. The patient was treated with intravenous corticoste...

Between November 1997 and April 20, 1998, bloody diarrhea sickened 298 persons in Cameroon. Laboratory investigation of the epidemic (case-fatality rate, 16.4%) documented amoebiasis in one of three patients and three types of pathogens: multidrug-resistant Shigella dysenteriae type 1, S. boydii, and enterohemorrhagic Escherichia coli. We report the first isolation of E. coli O157:H7 in Cameroo...

We report a case of parasitism by Rhabditis sp in a five-month-old child, from Goiás State, Brazil. He had a history of diarrhea with liquid and green faeces which later became bloody. Parasitological examination revealed the presence of larvae and adult female of Rhabditis sp. We used thiabendazole in this case after which the child improved. The authors suggest a better differential diagnosti...

We report the case of an octagenerian who presented with leukocytoclastic vasculitis as the first symptom of Crohn's disease. The patient was admitted with skin rash on the lower extremities and ankles and episodes of bloody diarrhea. Skin and colon biopsies revealed acute leukocytoclastic vasculitis and moderate Crohn's disease, respectively. The patient was treated with intravenous corticoste...

The term “thrombotic microangiopathy” (TMA) encompasses non-inflammatory small vessel vasculopathies that are caused by severe endothelial and medial smooth muscle cell injury/necrosis. TMAs can be promoted by a variety of “toxic” stimuli ranging from malignant range hypertension, E. coli infections with bloody diarrhea, radiation, systemic diseases such as scleroderma to iatrogenic events such...
