The Significance of Human Double Zone Beta Hemolytic Streptococci in the Udder of the Cow
Human strains of double zone beta hemolytic streptococci produced mastitis in 11 quarters of 4 young cows. Following the acute phase of the infection, the streptococci were eliminated from 6 quarters at various intervals. However, sufficient positive infections were maintained throughout the period of observation to show that the human strains can produce the same degree of infection as bovine ...
متن کاملGroup B beta-hemolytic streptococci causing pharyngitis.
Group B beta-hemolytic streptococci were isolated from the throats of 49 of 1,110 patients who had pharyngitis. Compared with patients whose throat cultures were negative for beta-hemolytic streptococci, those harboring group B were more likely to have enlarged tonsils (P less than 0.001), exudate (P less than 0.02), and tender enlarged anterior cervical lymph nodes (P less than 0.01). Group B ...

متن کاملGrouping of Beta-hemolytic Streptococci on Cellulose Acetate Membranes.
distinguished from the color of fluorescein isothiocyanate. Figure 1 shows the mycelium and the cell walls stained by the method described. The staining reaction of these preparations could be observed as far as a 1:16 dilution of the antiserum. These results suggest that a-amylase may be located on the cell surfaces where the antibody molecules were accessible, although there is no information...
متن کاملBacitracin and coagglutination for grouping of beta-hemolytic streptococci.
Bacitracin may be used for presumptive differentiation of group A from other beta-hemolytic streptococci. Whatever criteria are used for the test, a small number of erroneous results will be obtained. With the 1,161 strains studied in this laboratory, using a zone of 10 mm or greater as indicative of group A was better than using Maxted's original criterion of any zone of inhibition for group A...
