Isolation of an Obligately Anaerobic Bacillus from the Feces of Newborn Infants and from Other Human Sources, and Its Probable Identity with the “Köpfchenbakterien” of Escherich, Rodella's “Bacillus III,” andBacillus paraputrificus(Bienstock)

The Identity of “Bacillus innutritus” (Kleinschmidt) and Bacillus paraputrificus (Bienstock)

“…

From time to time, over a period of many years, we have recovered from the feces of infants and children, from fecallycontaminated surgical wounds, from a decubitus ulcer, and from post-mortem cultures from the heart blood, peritoneal and pleural fluids in adults, a species of anaerobic bacillus whose close resemblance to the "Kopfchenbacterien" or Escherich was finally pointed out by Hall and O'Toole (1935) and whose identity with the Bacillus paraputrificus of Bienstock was shown by Hall and Snyder (1934).In 1934, Kleinschmidt of Cologne, Germany, reported an anaerobic bacillus occurring in the stools of infants at periods of malnutrition, which in his opinion differed from previously described bacteria and which he called "Bacillus innutritus. "The description of "B. innutritus" was at once suggestive of B. paraputrificus, and it so happened that the senior author was able personally to visit Dr. Kleinschmidt in the Kinderklinik der Stadtische Krankenanstalt Lindenborg and to secure two strains of "B. innutritus" for comparison.
