Necrotic typhlocolitis related to spirochete infection is a pathological condition commonly found in birds in the wild or bred in captivity. Though this pathology has been reproduced experimentally, the role of the spirochete, whether primary or secondary in these episodes, has not yet been established. On gross examination of many black grouses (Lyrurus tetrix) (young subjects 80 days of age), revealed severe anatomopathological signs suggestive of necrotic hemorrhagic typhlocolitis. The negativity of parassitological tests conducted on contents of the intestine and of scrapings from the enteric mucosa, exclude protozoal infection and have lead to further histo-pathological tests carried out using particular histochemical techniques. The observation of a massive presence of spirochetes in all of the samples examined would suggest definite role of this microorganism, along with other factors, in the genesis of severe intestinal lesions and of the incidence of mortality
