) Risk-focused sero-surveillance surveillance (cont.) Focusing can be achieved by reference to some or all of the following: – Historical disease patterns (prior probability mapping) – clinical, participatory and laboratorybased – Critical population size, structure and density – Livestock husbandry and farming systems – Movement and contact patterns – markets and other trade-related movements – Transmission parameters (e.g. virulence of the strain, animal movements) – Wildlife and other species demography. 26
Selection of cattle and buffaloes for serosurveillance Ageing cattle and Asian buffaloes for the purpose of serosurveillance: Mis-ageing of cattle selected for serosurveillance is the most common source of error. Colostral immunity can persist almost up to one year of age when measured by the H c-ELISA. Thus, it is essential to exclude from sampling buffaloes and cattle less than one year of age. In addition, it is frequently necessary to be able to exclude those which are older than a certain age, for example, to select only those born after cessation of vaccination. Accounts of the ages for eruption of the incisor teeth vary markedly and are clearly dependent on species, breed, nutritional status and nature of the feed. 27
