The consumption of milk and unpasteurized dairy products contaminated with Brucella bacteria is one of the most important ways of brucellosis transmission to humans. The principal goal of this study was to determine the prevalence of () and () in unpasteurized dairy products consumed in Shiraz province. In this study conducted in 2016, 238 unpasteurized dairy products including 48 raw milk, 48 yogurt, 46 cheeses, 48 dough and 48 ice cream samples, were purchased from the retail market in Shiraz province and were examined by a specific PCR assay. This study showed positive 5/04% out of 238 unpasteurized dairy products including 9 out of 48 (18/75%) raw milk samples and 3 out of 48 (6.25%) yogurt samples). Contamination was not detected in samples of dough, cheese and traditional ice cream. The results also showed that among 12 positive samples, 6 samples were contaminated with (including 4 milk samples and 2 yogurt samples), 2 samples were contaminated with (including 2 Milk samples) and 4 samples were contaminated simultaneously with and (including 3 milk samples and 1 yogurt sample). The present study suggests the unpasteurized dairy products as the major sources of brucellosis in Shiraz province, South of Iran; thus, to prevent brucellosis in human, the consumption of pasteurized milk and dairy products is highly recommended.
食用被布鲁氏菌污染的牛奶和未经巴氏杀菌的乳制品是布鲁氏菌病传播给人类的最重要途径之一。本研究的主要目的是确定设拉子省消费的未经巴氏杀菌的乳制品中（）和（）的流行情况。在这项于2016年进行的研究中，从设拉子省的零售市场购买了238份未经巴氏杀菌的乳制品，包括48份生牛奶、48份酸奶、46份奶酪、48份面团和48份冰淇淋样品，并通过特定的PCR检测进行检查。这项研究显示，在238份未经巴氏杀菌的乳制品中，阳性率为5.04%，其中包括48份生牛奶样品中的9份（18.75%）和48份酸奶样品中的3份（6.25%）。在面团、奶酪和传统冰淇淋样品中未检测到污染。结果还显示，在12份阳性样品中，6份样品被（包括4份牛奶样品和2份酸奶样品）污染，2份样品被（包括2份牛奶样品）污染，4份样品同时被和污染（包括3份牛奶样品和1份酸奶样品）。本研究表明，未经巴氏杀菌的乳制品是伊朗南部设拉子省布鲁氏菌病的主要来源；因此，为预防人类布鲁氏菌病强烈建议食用巴氏杀菌的牛奶和乳制品。
