Studies on an Uncomplicated Coryza of the Domestic Fowl

Minute coccobacilliform bodies have regularly been found in the nasal exudate of fowl infected both by injection and by contact with the coryza of slow onset. These bodies are commonly less than 0.5micro in diameter and are predominantly extracellular. They have consistently failed to grow in artificial media. They are held back by Berkefeld V filters which are impermeable to Hemophilus gallina...

Histochemical Detection of Glycoconjugates in the Anterior Lingual Salivary Glands of the Domestic Fowl

Glycoconjugates in secretory epithelium of the anterior lingual salivary glands of chicken have been studied by means of light microscopic histochemical methods. A series of staining procedures were employed including peroxidase labeled lectin diaminobenzidine methods and digestion techniques with neuraminidase or α amylase. The terminal portion of the anterior lingual gland consisted of mucous...

Studies on Fowl Leukosis

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...

On the Frequency of Spontaneous Tumors in the Domestic Fowl

1. Analysis of records from the Storrs Contest, the Harper Adams Trials, and a farm flock indicate an increase of tumors in the second half of the pullet year (May through October) over the first half (November through April). 2. Some evidence seems to indicate that heavy antecedent egg production is associated with a rise in tumor rate. 3. The normal annual tumor rate for fowls between the age...
