Certain factors of climate are favorable to streptococcus respiratory diseases. In those tropical environments where hemolytic streptococcus is unusual in the throat flora, scarlet fever is unknown and rheumatic fever rare. In New York City, however, following epidemic waves of pharyngitis with hemolytic streptococcus the incidence of rheumatic fever rises precipitously. The correlation between...

Young male rats (115 g) were maintained on diets containing 4-8 mg of magnesium per 100 g of diet for 12 wk. By 3 wk the characteristic features of magnesium deprivation developed, including decreased plasma and tissue magnesium concentration, growth retardation, ruffled fur, patchy dermatitis, irritability, hyperemia of acral parts, onychymegaly, and in the most severely restricted, premature ...

equine infectious anemia (eia) is a contagious disease that is clinically characterized by recurrent episodes of fever, hemolytic anemia, icterus, depression, edema and chronic weight loss. the disease is associated with a persistent viral infection. the virus of eia is a member of the retroviridae family. the aim of this study was to determine the status of eia in horses in ahvaz. one hundred ...

preterm premature rupture of membrane(PPROM)is one of the serious problems during pregnancy.the aim of this study was to determine the probable relation between group B streptococal and anaerobic infections and PPROM.for this porpust 100 pregnant women with preterm rupture of membrane were selected.in the case group the prevalence of B-hemolytic streptococcal and anaerobic microorganisms was de...

Hemolytic disease of the newborn (HDN), with high potential for increased fetal loss is less common now, due to the universal screening for iso-sensitization and also because of appropriate use of antenatal anti-RhD antibody prophylaxis. There are other non-RhD antibodies that can cause HDN. In US, we occasionally encounter a highly sensitized fetus with significant morbidity and mortality. In ...

1. Minute beta hemolytic streptococci were found to occur from one-third to one-half as frequently in normal individuals as do ordinary beta hemolytic streptococci. 2. They were rarely isolated from the rhinopharynges of individuals suffering from chronic disease. 3. In acute respiratory tract infection other than that due to the ordinary beta hemolytic streptococcus the incidence of minute str...

By ISRAEL DAVIDSOHN, DAVID HERMONI AND ELEANOR G. HANAWALT H EMOLYTIC ANEMIA was one of the first diseases of blood produced artificially and studied in animals. Much valuable information has been gathered in this way. However, some moot points remain which require elucidation. In this paper experiment-s will be described which add to elucidation of the nature of a hitherto not fully understood...

By HAL CRAWFORD, B.SC., MARIE CUTBUSH, B.Sc., AND P. L. M0LLI50N, M.D., M.R.C.P. T HE DIAGNOSIS of hemolytic disease of the newborn is made by demonstrating incompatibility between the mother’s serum and the infant’s red cells, associated w-ith signs of red cell destruction in the infant . When the disease is due to anti-Rh itis not uncommoui to find evidence of serologic incompatibility, inclu...

W HEN THRICE-WASHED RED CELLS are agglutinated by rabbit anti-human-globulin sera (Coombs’ reagent), they are said to be “coated” with an “incomplete” (blocking) antibody.1 Such coating occurs in vivo in erythroblastosis fetalis as a result of placental transfer of maternal isoantibody, and in acquired hemolytic anemia of the immunologic variety2 (“autoimmune” hemolytic disease ) as a result of...
