Hemolytic Vibrio cholerae biotype El Tor strains were isolated in the United States in 1973 and 1978 after they had supposedly disappeared worldwide during the 1960s and 1970s. We decided to examine the change in prevalence of hemolytic El Tor strains since the beginning of the seventh pandemic and evaluate the usefulness of hemolytic activity as an epidemiological marker. A total of 48 isolate...

background and objectives: bordetella species colonize the respiratory tract of mammals and thereby cause the whooping cough. most of the species produce adenylate cyclase - a toxin ( hemolysin ) responsible for increasing intracellular cyclic amp (camp) levels in mammalian neutrophils and macrophages and as a consequence their phagocytic function get impaired . this study was carried out to is...

INTRODUCTION Hemolytic disease of the fetus and newborn is most commonly caused by anti-D alloantibody. It is usually seen in Rhesus D (RhD)-negative mothers that have been previously sensitized. We report here a case of hemolytic disease of the fetus and newborn in a newborn baby caused by anti-D and anti-S alloantibodies, born to a mother who was RhD negative, but with no previous serological...

The relation of the lethal toxin to the hemolysin produced by Clostridium septicum, strain 44, has been investigated. The following results suggest that the hemolytic and lethal actions of crude toxin are functions of a single substance or that they are functions of two substances which have similar physical, chemical, and antigenic properties. (1) Within the limits of experimental error, the l...

Hemolytic uremic syndrome (HUS) is one of the common causes of acute renal failure in children and is characterized by microangiopathic hemolytic anemia and thrombocytopenia. About 5% to 10% of all HUS cases in children are non-diarrheal HUS (atypical HUS) [1,2]. Many triggering causes of atypical HUS, such as non-enteric infections, viruses, drugs, systemic diseases, glomerulopathies, malignan...

The Kidd blood group is clinically significant since the Jk antibodies can cause acute and delayed transfusion reactions as well as hemolytic disease of newborn (HDN). In general, HDN due to anti-Jk(b) incompatibility is rare and it usually displays mild clinical symptoms with a favorable prognosis. Yet, we apparently experienced the second case of HDN due to anti-Jk(b) with severe clinical sym...

Hemolytic uremic syndrome (HUS) is defined by the triad of mechanical intravascular hemolytic anemia with schistocytosis, thrombocytopenia and acute renal failure. Pulmonary involvement in HUS is known to be rare. We present the case of a 25-year-old male with diffuse alveolar hemorrhage and myocarditis followed by atypical hemolytic uremic syndrome. In this case, successful treatments included...
