Treatment of host cells with Concanavalin A prevents the assembly or release of fowl plague virus from chick fibroblasts and inhibits fusion of BHK cells by the paramyxovirus SV5. Metabolic events of the host cells are not greatly impaired during the early phase of infection. There is evi dence that the carbohydrate moiety of the Con A receptor of fowl plague virus is associated with the viral ...

The fertilizing capacity, motility and ultrastructure of fowl and turkey spermatozoa were examined at various stages of the freezing process. For both species, fertility and motility were depressed after equilibration with dimethyl-sulphoxide at 5 degrees C. After freezing, motility was maintained at 55% for fowl spermatozoa and 40% for turkey spermatozoa; however, fertility was 55% for the fow...

the present work aimed at studying growth pattern and carcass traits in pearl grey guinea fowl fed on dietary neem (azadirachta indica) leaf powder (nlp) over a period of 12 weeks. day old guinea fowl keets (n=120) were randomly assigned to four treatment groups, each with 3 replicates. the first treatment was designated as control (t0) in which no supplement was added to the feed, while in tre...

Following the observations on high-speed centrifugation of the avian sarcoma agent by various investigators,1' 8,10,11,12 similar studies of the agent of fowl leukosis have been undertaken. Since the neoplastic nature of this disease is now rather generally recognized, observations on the filterable agent of chicken leukosis have assumed new significance for the study of the etiology of fowl ne...

1. The spontaneous occurrence of myeloid leukemia of the fowl is confirmed 2. Myeloid leukemia of the fowl is transmissible by intravenous or intraperitoneal injection of an organic emulsion. The latter is in confirmation of the work of Ellermann and Bang (6, 7), who first successfully transmitted the disease. They were followed by Hirschfeld and Jacoby (13)) whose successful transmissions, how...

Evidence is presented that the growth capacity of chick embryo tissue for the fowl coryza bodies is conditioned by a diffusible cellular component which is essential for their multiplication. This growth factor is inactivated at pH 6, but withstands a temperature of 100 degrees C. for 60 minutes. An amount sufficient to promote a normal growth of the specific bodies may be present in tissue cul...

The membrane pacemaker hypothesis predicts that long-living species will have more peroxidation-resistant membrane lipids than shorter living species. We tested this hypothesis by comparing the fatty acid composition of heart phospholipids from long-living Procellariiformes (petrels and albatrosses) to those of shorter living Galliformes (fowl). The seabirds were obtained from by-catch of comme...

The data on ten SNP markers of Myostatin gene (GDF-8) was generated on nine breeds/populations of indigenous poultry and Red Jungle Fowl (RJF). The SNPs were five in promoter region, one each in intron 1 and 2 and three in exon 1. The data was analyzed to find out the genetic relationship among the indigenous chicken populations. PCR-RFLP was carried out to genotype the populations at seven SNP...

Two outbreaks of fowl cholera on a multiage free-range egg farm were investigated. The outbreaks occurred in 1994 and 2002. A total of 22 strains of Pasteurella multocida were available for study, 11 from the 1994 outbreak and 11 from the 2002 outbreak. Lesions typical of acute fowl cholera were seen in the 1994 outbreak, whereas both acute and chronic fowl cholera occurred in the 2002 outbreak...
