Social context affects testosterone-induced singing and the volume of song control nuclei in male canaries (Serinus canaria).
female partner on the rate of song produced by male canaries. In the first experiment, song rate was measured in dyads composed of one male and one female (M-F) or two males (M-M). Birds were implanted ...
Avian influenza: mini-review, European control measures and current situation in Asia.
contagious disease for birds, which can easily take epidemic proportions when appropriate and efficacious measures are not taken immediately. Influenza viruses can vary in pathogenicity from low to medium or ...
Helicobacter cynogastricus sp. nov., isolated from the canine gastric mucosa.
study. The tightly coiled organism, measuring 10-18 mum long and up to 1 mum wide, was motile by means of multiple sheathed flagella located at both ends of the cell and by a periplasmic fibril running ...
Ochratoxin A and citrinin loads in stored wheat grains: impact of grain dust and possible prediction using ergosterol measurement.
storage conditions. We therefore, recommend taking precautionary measures not only by controlling and maintaining moisture at a reasonable level during storage of the raw materials but also by paying more ...
Detection of BVDV persistently infected animals in Belgium: evaluation of the strategy implemented.
A first evaluation of the measures already applied in Belgium is presented. Data obtained in 2003 are presented and discussed regarding the validation of the laboratory strategy, the prevalence of positive ...
The occurrence of encephalomyocarditis virus (EMCV) in European pigs from 1990 to 2001.
(110), Greece (15) and Cyprus (6). The outbreaks appeared to be clustered in ‘endemic areas’ with an increase in outbreaks during the autumn and winter months. The within-herd seroprevalence measured in ...
Transmission of classical swine fever. A review.
pig diseases. Basic measures to control epidemics of CSF comprise eradication of infected herds and preventive emptying of herds at risk. Identification of these herds at risk is based on knowledge of ...
Assessment of the cell-mediated immune response in chickens by detection of chicken interferon-gamma in response to mitogen and recall Newcastle disease viral antigen stimulation.
was observed, production of ChIFN-gamma could be measured by ELISA. In our hands, the combination of ionomycin and phorbol-12-myristate 13-acetate or the use of recombinant chicken interleukin-2 gave ...
Protein growth rate in rainbow trout (Oncorhynchus mykiss) is negatively correlated to liver 20S proteasome activity.
degradation, would be negatively correlated with growth rate. In order to test this hypothesis we maintained rainbow trout for 62 days, during which repeat measurements of food consumption and growth were made. ...
Real-time PCR for simultaneous detection and genotyping of bovine viral diarrhea virus.
isolates of both genotypes. The application to clinical diagnosis was evaluated on pooled blood samples by post run measurement of the FAM- and VIC-associated fluorescence. The 100% agreement with the ...
