A natural outbreak of Newcastle disease (ND) was reported in a flock of guinea-fowl in Nigeria, affecting 1,029 birds of which 250 (24.3%) died. Paralysis of the legs and wings, coughing, sneezing, white diarrhoea and complete cessation of egg production were observed. Serum samples collected at the onset and during the course of the disease had high ND antibody titres. ND virus was isolated fr...

Today the developments in genetics are exciting. Perhaps this explains why geneticists sometimes seem to overlook common sense solutions. One example of this is the selection experiment done by Bijma et al. (2007a,b). These authors developed a sophisticated statistical method of group selection against mortality in hens randomly placed together. One may safely assume that this mortality is due ...

In view of the possible use of viruses for the immunotherapy of breast cancer, the replication of a strain of fowl plaque virus was studied in the tumor cells of 11 mammary carcinoma patients with malignant effusions. The tumor cells were obtained by centrifugation on iodamide solutions, then cultured in vitro, and infected by a fowl plaque virus previously adapted to grow in a mammary carcinom...

1. A simple, direct method of counting leucocytes of the fowl is described. 2. Twenty-nine complete, morphological studies of the blood of eleven domestic fowls are recorded. 3. The characteristics of the cells found in the blood and bone marrow are described in detail and their relative numbers reported. 4. The supravital technique, using neutral red and Janus green, enables one to separate an...
