The mucosa of the abomasum is a strongly acidic and therefore germ poor, but not entirely germfree environment. Only in isolated areas of the fundic glands zone were straight rods in the foveolas, and even more seldom spiral shaped bacteria could be encountered. They had no relation to the inflammatory infiltrates. On the other hand, Campylobacter-like organisms were more often observed in the pyloric region and, preferably, in a narrow zone following the cutaneous mucosa of the omasum. These organisms appeared to have a different size (1.3 to 2.4 microns length and 0.4 to 0.8 microns width) and they occurred deep inside the glands in an almost pure fashion. Whereas they caused no visible reaction of the tissue in the narrow cardiac zone, their occurrence in the pyloric region was several times connected with neutrophilic-rich infiltration. It ought to be tested, whether Helicobacter are among these Campylobacter-like organisms, which cause a disease leading up to ulcerations in calves similar to gastritis B in humans.
