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...

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...

INTRODUCTION Hemolytic disease of the newborn was first described in the medical literature 1609, when it was diagnosed in one French housewife. In 1932 Diamond and colleagues described the mutual relationship of fetal hydrops, jaundice, anemia and erythoblastosis, which was later called fetal erytroblastosis. Hemolytic disease of the newborn (HDN) in the strict sense is considered disease whos...

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...

While group C beta hemolytic streptococcal infections are uncommon in humans, group C beta hemolytic streptococcal pneumonia is exceedingly rare. To the best of our knowledge, only 2 cases of necrotizing pneumonia caused by group C beta hemolytic streptococcus have been reported in the past. Thus, we are reporting a rare case of necrotizing group C beta hemolytic streptococcal pneumonia in a y...

A 62-year-old man having prostate cancer presenting with hemolytic jaundice is reported. The hemolytic jaundice was cured by diethylstilbestrol diphosphate (DES-P) treatment, but the patient died one year and two months later from relapse of prostate cancer. An autopsy confirmed the diagnosis of prostate cancer with multiple metastases. Sudden anemia caused by bone metastasis might have caused ...

Coombs' positive hemolytic anemia is exceedingly rare in tuberculosis. We herein report a patient with tuberculosis associated with Coombs' positive hemolytic anemia that was responded to antituberculosis therapy. She was admitted to the hospital because of recent-onset fatigue, weakness, nonproductive cough, pallor and scleral jaundice. Coombs positive hemolytic anemia and pulmoner tuberculosi...
