Нами был применен метод баркодинга ДНК для таксономической идентификации рыбных ингредиентов (лосось, тунец, летучая рыба, акула) в продуктах японской кухни. Были проанализированы 27 образцов из 6 точек розничной торговли и 3 ресторанов в Воронеже. В качестве «лосося» все выбранные коммерческие компании использовали филе атлантического лосося или семги (Salmo salar), который считается менее ценным, чем тихоокеанский лосось. Результаты баркодинга ДНК показали, что один из образцов «лосося» заменен на желтоперого тунца. Также один образец «тунца» был заменен на филе атлантического лосося. При анализе «икры летучей рыбы» только один образец соответствовал искомой ДНК, а именно ласточкокрылу обыкновенному (Hirundichthys affinis). В остальных образцах была идентифицирована ДНК мойвы (Mallotus villosus). При анализе образца «акула» была идентифицирована ДНК мозамбикской тиляпии, которая является пресноводной рыбой. При анализе «двоящихся» сиквенсов нами было показано, что в двух образцах «икры летучей рыбы» была смесь икры ласточкокрыла обыкновенного и мойвы. Примечательно, что в одном из образцов «лосось» на основе баркодинга ДНК была идентифицирована бактерия Pseudomonas fluorescens. Анализ «двоящихся» сиквенсов образцов «лосось» также показал примесь ДНК этой бактерии. При последующем анализе мяса лосося с использованием видоспецифичных праймеров к этой бактерии она была идентифицирована во всех образцах. P. fluorescens вызывает заболевание у лососевых рыб и может быть опасной для людей с низким уровнем иммунитета. Показано, что праймеры, используемые для баркодинга ДНК, имеют высокую степень гомологии с ДНК бактерий группы P. fluorescens.</p></abstract><trans-abstract xml:lang="en"><p>DNA barcoding as a tool for genetic certification and identification of taxonomic membership of organisms has recently become very popular. We have applied DNA barcoding method for taxonomic identification of fish ingredients (salmon, tuna, flying fish roe, shark) in product of Japanese cuisine. We have analyzed 27 samples from 6 retail outlets and 3 restaurants of the city of Voronezh. It was found that for products designated as containing “salmon” in all selected outlets were used as a fillet of Atlantic salmon (Salmo salar), which is considerably less valuable than Pacific salmon. Results of DNA barcoding showed that one of the samples of «salmon» was in fact, yellowfin tuna, whereas one sample of “tuna” was a fillet of Atlantic salmon. However in general, the “salmon” and “tuna” samples were substituted infrequently. Analysis of “flying fish roe” samples revealed that only one sample from 6 was really Fourwing flyingfish (Hirundichthys affinis). The remaining samples were identified as DNA of capelin (Mallotus villosus). By analyzing the “double” sequences in 2 samples, we have found that two samples of «flying fish roe» were mixtures of Fourwing flyingfish roe and capelin roe. A sample labeled “shark” was identified as Mozambique tilapia. This species is a freshwater fish. Bacterium Pseudomonas fluorescens was identified in one of the “salmon” samples. Analysis of “double” sequences of “salmon” samples revealed presence of P. fluorescens DNA. Analysis of salmon meat with the use of species-specific primers for this bacterium revealed contamination of all samples by P. fluorescens. This bacterium causes the disease in salmon and can be harmful to patients with compromised immune systems. Primers used for DNA barcoding were shown to have high homology to DNA of bacterial group P. fluorescens.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>баркодинг ДНК</kwd><kwd>цитохромоксидаза</kwd><kwd>рыбный ингредиент</kwd><kwd>идентификация</kwd><kwd>Pseudomonas fluorescens</kwd><kwd>загрязнение</kwd><kwd>DNA barcoding</kwd><kwd>cytochrome oxidase</kwd><kwd>fish ingredients</kwd><kwd>identification</kwd><kwd>Pseudomonas fluorescence</kwd><kwd>contamination</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hebert P.D., Gregory T.R.
