Some of the leading bacteriologists consider this a very valuable test. The so-called hog cholera group or the Gaertner group of bacilli is important from the standpoint of the food bacteriologist. The Gaertner group occupy a position intermediate between the chemically active coli group and the chemically inert typhoid group and includes the following important species or rather strains âthe Bacillus enteritidis strain which includes many of the bacteria isolated in cases of food poisoning and some of the B. typhi murium.
