 In 1937 the Norwegian pathologist Leiv Kreyberg was allowed to examine one of Reich 's bion preparations under a microscope . Kreyberg wrote that the broth Reich had used as his culture medium was indeed sterile , but that the bacteria were ordinary staphylococci . He concluded that Reich 's control measures to prevent infection from airborne bacteria were not as foolproof as Reich believed . Kreyberg accused Reich of being ignorant of basic bacteriological and anatomical facts , while Reich accused Kreyberg of having failed to recognize living cancer cells under magnification .
