초록

국내 유통되는 반려동물 사료의 살모넬라 분석시 증균배양법, 효소면역기법에 의한 분석, 종 특이 primer를 활용한 PCR 방법을 활용하여 비교 평가하였다. 시료 175점 Salmonella spp. 검출 결과 증균배양법 및 종 특이 primer를 활용한 PCR 방법에 의한 검출 방법에서 2점의 시료(육포, 옥수수 글루텐)가 양성으로 확인되었고, 효소면역기법에 의한 검출방법에서는 1점의 시료(옥수수 글루텐)가 양성으로 확인되었다. 증균배양법 및 효소면역기법에 의한 검출방법에 비해 종 특이 primer를 활용한 PCR 방법을 적용 할 경우 시료에서 분리된 균주의 종(species) 판별이 가능하였다.

The purpose of this study was to compare the conventional culture method, enzyme immune method and the PCR method using species-specific primer in the analysis on the Salmonella spp. found in domestically distributed pet foods. For the study, Salmonella spp. were detected from 175 samples. From the conventional culture method and the PCR method, two samples (jerky and corn gluten) were determined as positive. Also, from the enzyme immune method, one sample (corn gluten) was test-positive. The study revealed that application of the PCR method with species-specific primer allows better distinguishment between the species of the strain collected from the samples than the conventional culture method and/or the enzyme immune method.
