[The etiology of foul brood].
Five hundred and thirty-six samples of honeycombs were examined in a laboratory in the years 1971-1974. In all the samples clinically determined as the foul brood, B. alvei was isolated as a pure culture, and enterococci, or both microorganisms were isolated in mixed form. Twenty-five strains of the isolated streptococci were analyzed microbiologically and biochemically; on the basis of their culture and biochemical characteristics five strains were designated as Streptococcus faecalis, 14 strains as Streptococcus faecalis var. liquefaciens, five strains as Streptococcus faecium and one strain as Streptococcus durans. After checking the used taxonomic key of the culture and biochemical classification of B. alvei it may be stated that the culture and biochemical characteristics are stable. The strains of B. alvei (very dried strains), which persisted in the dried slant meat-peptone agar, were viable under the laboratory conditions, which proves the high resistance of the spores to the environment.
