PG - 1135-9 LID - 10.1128/AEM.01803-10 [doi] AB - We compared ileal Clostridium perfringens quantification results produced by real-time PCR and culture-based methods in broiler chickens in a challenge model of necrotic enteritis. Assessment of the relative standard deviations (RSDs) revealed that the real-time PCR assay generated a smaller standard deviation and thus was more precise than the culture-based method. Linear regression analysis indicated that the bacterial counts of these two methods were highly correlated (R(2) = 0.845). We suggest that real-time PCR could be a replacement of the culture method for quantifying C. perfringens in the intestinal tracts of broiler chickens.
