Efficiency of Two Air Sampler for Determination of Mesophilic Bacteria in Laying Hen Flock

摘要：

　　The air in laying hen houses contains high concentrations of airborne hacteria.The numhers of these bacteria can be influenced by the efficiency of the chosen sampling method.In this study we compared AGI-30 Impingers and the Coriolis(R)μ air Sampler in terms of their efficiency of sampling aerobic mesophilic bacteria in a laying hen house for 6 week during of the laying period.The numbers of mesophilic airborne bacteria ranged from 8×104 to 2×106 CFU/m-3 when sampled using ACI-30 Impingers and from 2×105 t0 4 x 106CFU/m-3 when sarupled using the Coriolis(R)μ air Sampler.The concentrations detected simultaneously by hoth devices correlated well(rPearson=0.755); hut the Coriolis(R)μ air Sampler showed a significantly higher sampling efficiency (P <0.001).The Coriolis (R)μ promises to be a useful technique to quantify aerohic mesophilic bacteria in poultry houses efficiently.
