BACKGROUND We describe an outbreak of gastroenteritis and the hemolytic-uremic syndrome caused by Shiga-toxin-producing Escherichia coli in Germany in May, June, and July, 2011. The consumption of sprouts was identified as the most likely vehicle of infection. METHODS We analyzed data from reports in Germany of Shiga-toxin-producing E. coli gastroenteritis and the hemolytic-uremic syndrome an...
1. The hemophilic bacilli can be divided into two large groups according to the ability of certain strains to produce hemolysis. 2. Both the hemolytic and the non-hemolytic groups may be further subdivided according to the ability of some strains to produce indole, to form gas, and to ferment certain carbohydrates. 3. The hemophilic bacilli of both the hemolytic and the non-hemolytic varieties ...
The in vitro hemolytic activity of 4 isolates of Trichomonas vaginal& was investigated. Repetitive hemolysis assays of any one isolate showed cyclical fluctuations in hemolytic activity, varying over 24 hr of continuous culture. Maximal hemolytic activity was detected using trichomonads in the lag phase of the growth cycle. Investigations showed that hemolysis was a contact-dependent phenomenon...
Hemolytic disease of the newborn due to ABO incompatibility was first observed by Halbrecht in 1944. This entity has a spectrum ranging from minimal hemolysis requiring no therapy, as is the case in most instances, to severe hemolytic disease requiring aggressive management including exchange transfusion in a small percentage of cases. An extreme degree of hemolytic disease of the newborn due t...
Cholelithiasis is an unusual complication of hemolytic uremic syndrome. A 12-year-old boy with hemolytic uremic syndrome, established by renal biopsy, who developed cholestatic jaundice is presented here. Laboratory results for secondary causes of hemolytic uremic syndrome were normal. Abdominal ultrasonography and magnetic resonance cholangiopancreatography revealed extrahepatic obstruction. A...
Hemolytic-uremic syndrome is defined by a combination between renal failure, microangiopathic hemolytic anemia and thrombocytopenia; it usually appears in young children, is preceded by gastrointestinal enteritis and may involve other organs as well. The purpose of this article is to present a series of four cases of lethal hemolytic uremic syndrome and discuss its legal medicine consequences. ...
Bendamustine is an alkylating agent approved for the treatment of chronic lymphocytic leukemia (CLL) and B-cell non-Hodgkin lymphoma. There are scant reports on bendamustine-induced immune hemolytic anemia occurring mainly in CLL patients. We report a case of immune hemolytic anemia that developed after exposure to bendamustine in a 70-year-old female with CLL who was previously exposed to flud...
We recovered a non-beta-hemolytic Streptococcus pyogenes strain from a severe soft tissue infection. In this isolate, we detected a premature stop codon within the sagC gene of the streptolysin S (SLS) biosynthetic operon. Reintroduction of full-length sagC gene on a plasmid vector restored the beta-hemolytic phenotype to our clinical isolate, indicating that the point mutation in sagC accounte...
The hemolytic lectin CEL-III and its site-directed mutants were expressed in Escherichia coli cells. Replacement of the valine clusters in domain 3 with alanine residues led to increased self-oligomerization in solution and higher hemolytic activity. The results suggest the involvement of these valine clusters in CEL-III oligomerization and hemolytic activity.
We determined total bilirubin, "direct" and "indirect" bilirubin fractions, and, in parallel, using Ektachem slides, the total, conjugated, unconjugated, and delta bilirubin contents for specimens from 88 adult inpatients at various times during hospitalization in a tertiary-care facility. We wanted to see if the results correlated with the patients' diagnoses, based on a review of medical reco...
