coli O157:H7 is the most pathogenic as it has been incriminated in various disease conditions such as hemolytic uremic syndrome, thrombotic thrombocytopenic purpura, and
hemorrhagic colitis [2].
Escherichia coli O157:H7, a cause of
hemorrhagic colitis and hemolytic uremic syndrome.
The success of determining the bleeding lesions was 100% when colonoscopy was performed on the first day (2 patients--bleeding diverticula and
hemorrhagic colitis).
Symptoms caused by EHEC include abdominal cramps and diarrhea that may in some cases progress to bloody diarrhea (
hemorrhagic colitis).
Hemorrhagic colitis associated with a rare Escherichia coli serotype.
coli O157:H7, including
hemorrhagic colitis, hemolytic uremic syndrome, and thrombotic thrombocytopenic purpura.
The following serious or clinically significant adverse events have been reported at a frequency less than or equal to 1% with PEGINTRON or interferon alpha: Severe decreases in neutrophil or platelet counts, hypothyroidism, hyperglycemia, hypotension, arrhythmia, ulcerative and
hemorrhagic colitis, development or exacerbation of autoimmune disorders including thyroiditis, RA, systemic lupus erythematosus, psoriasis, pulmonary disorders (dyspnea, pulmonary infiltrates, pneumonitis and pneumonia, some resulting in patient deaths), urticaria, angioedema, bronchoconstriction, anaphylaxis, retinal hemorrhages, and cotton wool spots.
The third patient was a 32-year-old man with
hemorrhagic colitis who began treatment with sulfasalazine.
coli O157:H7 has been a major cause of
hemorrhagic colitis and hemolytic uremic syndrome in North America.
Several strains, such as O157:H7, are known to provoke severe gastrointestinal problems including bloody diarrhea and
hemorrhagic colitis and can lead to serious health complications, including kidney failure.
coli usually belong to the serotype O157:H7 and were first associated with a multistate outbreak of
hemorrhagic colitis in 1982.
Verotoxigenic Escherichia coli (VTEC) can cause severe disease in humans, with signs and symptoms including diarrhea,
hemorrhagic colitis, and hemolytic uremic syndrome (1).
