Thrombotic thrombocytopenic purpura-hemolytic uremic syndrome occurs more commonly in women and among women is commonly associated with pregnancy. Case series of thrombotic thrombocytopenic purpura-hemolytic uremic syndrome from 1964 to 2002 were reviewed (1) to document the reports of occurrence of thrombotic thrombocytopenic purpura-hemolytic uremic syndrome during pregnancy and (2) to search...

1. Hemolytic streptococcus has been found in 100 per cent of the throats of patients with scarlet fever during the 1st week of the disease. 2. The average length of time that these organisms are present in the throat varies from 10 to 20 days. 3. No morphological or cultural characteristics peculiar to the hemolytic streptococcus from scarlet fever can be demonstrated. 4. Ten immune sera have b...

SYNOPSIS Erythrocytes may be coated with blood group antibodies with or without reacting complement or sometimes apparently with complement alone. This may occur in vivo in such conditions as autoimmune acquired haemolytic anaemia, haemolytic disease of the newborn, or after transfusions of incompatible blood. It may occur in vitro also by the deliberate sensitization of erythrocytes during lab...

BACKGROUND Acute rheumatic fever is a major cause of heart disease in Aboriginal Australians. The epidemiology differs from that observed in regions with temperate climates; streptococcal pharyngitis is reportedly rare, and pyoderma is highly prevalent. A link between pyoderma and acute rheumatic fever has been proposed but is yet to be proven. Group C beta-hemolytic streptococci and group G be...

The immunodiagnostic assessment of dogs suspected having immune-mediated hemolytic anemia (IMHA) is based on persistent autoagglutination erythrocytes (after three saline washes), marked spherocytosis, and a positive direct antiglobulin (Coombs’) test (DAT). However, the value using indirect (IAT) for detection anti-erythrocytic autoantibodies in serum from IMHA unclear. To evaluate IAT, leftov...

This study was designed to evaluate the role of E. coli α-hemolysin (HlyA) in the pathogenesis of canine pyometra, and on the immune response of canine endometrial epithelial and stromal cells. In Experiment 1, the clinical, hematological, biochemical and uterine histological characteristics of β-hemolytic and non-hemolytic E. coli pyometra bitches were compared. More (p < 0.05) metritis cases ...

OBJECTIVES The alkoxyacetic acids (AAAs) are urinary metabolites of alkoxyethanol solvents. It is well documented that these chemicals can cause acute hemolytic anemia in humans and laboratory animals. There are scarce data on the relative hemolytic activity of these acids. Likewise, information is lacking on the relationship between their hemolytic activity and physicochemical properties. The ...
