PCB and organochlorine pesticides in home-produced eggs in Belgium.

the soil. For ten selected locations, the concentration in soils, excreta and feed was measured, but no simple correlation between egg and feed or soil level could be established. Hexachlorohexane, ...

Humoral, cell-mediated and mucosal immunity induced by oculo-nasal vaccination of one-day-old SPF and conventional layer chicks with two different live Newcastle disease vaccines.

similar humoral immune-response was measured in blood and tears but a differential profile of cell-mediated immunity was observed according to the vaccine strain. The lung-associated humoral immunity was ...
