Good results were obtained by the use of a successive combination of periodate-lysine-paraformaldehyde fixation and diaminobenzidine reaction mixture. Viral antigens were detected type-specifically on infected cells. Type-specific antisera determined by the neutralization test were absorbed by the homologous type of virus-infected CEF, but not by the heterologous type of these cells. This test was more effective for detecting virus infectivity than the resistance-inducing factor test. Viral antigen was observed 2 days after inoculation with a large amount of the virus. The minimum infective dose of the virus for the antigen detection was 100 resistance-inducing units (RIU) per plate 4 days after infection, or 1 RIU per plate in CEF after two passages.</p>","PeriodicalId":76197,"journal":{"name":"National Institute of Animal Health quarterly","volume":"21 2","pages":"63-7"},"PeriodicalIF":0.0,"publicationDate":"1981-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17343492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Expired gas was collected at the nostril in almost all the hens. In the sitting position free from vocalization, feeding, drinking, panting, and restlessness, hens showed various forms of stable pattern of oxygen-gas curves. These forms were classified into three types, or the ascending, flat and descending types, with respect to the plateau inclination. The waves of carbon-dioxide were not always a mirror image of those of oxygen. The rate of occurrence of each type varied with the hen's postural position. The wave form was altered with the experimental body-rotation of the hen. When placed between the deflections of stable pattern, the episodes of wave deformation resembling that seen at the time of uneven pulmonary ventilation in mammals could frequently be observed in any hen's posture examined. Cardiogenic oscillation appeared on the plateau of expired-gas curves.</p>","PeriodicalId":76197,"journal":{"name":"National Institute of Animal Health quarterly","volume":"21 1","pages":"42-51"},"PeriodicalIF":0.0,"publicationDate":"1981-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17840002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of over twenty parameters involved in the model, the following three were used as input variables: (1) age of chickens at housing a1 (= 1 and 21); (2) size of flock at housing, N(a1) (= 100 and 1,000); and (3) geometric mean of the level of parentally conferred immunity at hatching, G(1) (= 0, 2, 8, and 32). The outputs were the graphic images demonstrating the chronological changes in a flock of innate resistance, parentally conferred immunity, and their sum, and the epizootic patterns composed of numbers of chickens at subclinical stage, clinically diseased, recovered, condemned, etc. at each age. As a result, stronger epizootics were produced at a lower level of parentally conferred immunity, and a higher age and a larger size of flocks.
