Eleven of 16 strains of streptococci (alpha, beta and gamma hemolytic) were inhibited by concentrations ranging from 0.2 to 12.5 microgm. per milliliter.

Seventy-four of 77 patients with undoubted bacterial endocarditis have had negative beta-hemolytic streptococcus skin tests, and all 77 have had negative alpha-hemolytic streptococcus skin tests.* ...

So far, 26 Israelis have been affected by this rare condition in 2024. Authorities suspect the cases are linked to contamination by a strain of the E. coli bacteria that produces a dangerous toxin.

The test, called BETA, distinguished beta-hemolytic bacteria from control bacteria with 100 percent accuracy in 6 hours on plates, and with 99 percent accuracy in liquid broth in an hour.

Worldwide, millions of people suffer from hemolysis, the breakdown of red blood cells, such as those afflicted with sickle-cell disease, malaria or sepsis. These patients face an unprecedented risk of ...
