Dondurulmuş Deniz Ürünlerinde Vibrio spp.’nin İlmiğe Dayalı İzotermal Amplifikasyon (Loop Mediated Isothermal Amplification, LAMP) Yöntemiyle Belirlenmesi

Öz:
Araştırmada, deniz ürünlerinde halk sağlığı bakımından yüksek riskli olarak tanımlanan Vibrio parahaemolyticus, V. vulnificus ve V. cholerae’nın varlığının belirlenmesi amaçlandı. Bu amaçla örneklerde etken tespiti için hızlı ve etkin bir yöntem olan İlmiğe Dayalı İzotermal Amplifikasyon (Loop Mediated Isothermal Amplification, LAMP) metodu kullanıldı. Araştırma materyali olarak farklı satış noktalarından temin edilen dondurulmuş deniz ürünleri kullanıldı (n=212). Örneklerde klasik kültür yöntemiyle etken izolasyonu için ISO / TS 21872-1:2007 ve ISO 21872-2:2007 yöntemleri uygulandı. Elde edilen şüpheli izolatlarda gerçekleştirilen DNA ekstraksiyonu sonrasında genus spesifik PCR reaksiyonuyla gyrB1 gen bölgesi hedeflenerek Vibrio spp. varlığı doğrulandı. Pozitif örneklere V. parahaemolyticus, V. vulnificus ve V. cholerae için sırasıyla toxR, vvhA ve ompW hedef gen bölgelerine yönelik LAMP primer setleri kullanılarak turbidite bazlı Real-Time LAMP uygulandı. Araştırma bulguları değerlendirildiğinde, klasik kültürel yöntemle örneklerin %16.98’inde (36/212) Vibrio spp. kontaminasyonu olduğu belirlendi. Bununla birlikte Vibrio spp. pozitif izolatlarda LAMP reaksiyonu bulgularına göre V. cholerae varlığı tespit edilemezken V. parahaemolyticus ve V. vulnificus kontaminasyon düzeyleri ise sırasıyla %36.1 (13/36) ve %5.5 (2/36) olarak saptandı. Bu çalışma, dondurulmuş muhafaza uygulanarak satışa sunulan deniz ürünlerinde V. parahaemolyticus ve V. vulnificus gibi patojenik suşların varlığının tespiti ve bu gıdaların vibriosis bakımından önemini ortaya koymaktadır. Bu bağlamda deniz ürünlerinde dondurulmuş muhafaza öncesi mikrobiyal kalitenin ve muhafaza esnasındaki koşulların ve hijyenik standartların oluşturulmasının önemli olduğu düşünülmektedir.

Presence of Vibrio spp. in Frozen Seafoods by Loop Mediated Isothermal Amplification (LAMP) Method

Öz:
In the study, it was aimed to determine the presence of Vibrio parahaemolyticus, V. vulnificus and V. cholerae, which are defined as high risk for public health in seafood. For this purpose, Loop Mediated Isothermal Amplification (LAMP) method, which is a fast an d effective method for agent detection in samples, was used. Frozen seafoods obtained from different sales points were used as research material (n=212). ISO / TS 21872-1:2007 and ISO 21872-2:2007 methods were applied for the isolation from the samples using the classical cultural method. After DNA extraction performed on the suspected isolates, presence of Vibrio spp. was confirmed by genus-specific PCR reaction using the gyrB1 gene region. A turbidity-based Real-Time LAMP was applied to positive samples using LAMP primer sets for V. parahaemolyticus, V. vulnificus and V. cholerae targeted gene regions of toxR, vvhA and ompW, respectively. When the results were evaluated, it was determined that 16.98% (36/212) of the samples were contaminated with Vibrio spp. using the classical cultural method. However, the presence of V. cholerae could not be detected in Vibrio spp. positive isolates according to the LAMP reaction, while the contamination levels of V. parahaemolyticus and V. vulnificus were found to be 36.1% (13/36) and 5.5% (2/36), respectively. This study reveals the presence of pathogenic strains such as V. parahaemolyticus and V. vulnificus in seafood products sold in frozen storage and the importance of these foods in terms of vibriosis. In this context, it is thought that it is importan t to establish microbial quality before frozen storage, conditions during storage and hygienic standards in frozen seafood.
