Визначено ПЛР-профілі 12 архівних культур лістерій, що були виділені від різних видів тварин і зберігаються в колекції мікроорганізмів ННЦ «ІЕКВМ». Встановлено, що 10 ізолятів налічують гени prs, inlB, inlA, inlC, inlJ, actA, plcB, hly, iap, що характеризує їх як високовірулетних. Ізолят L. monocytogenes 61052 не містив ген inlА, а у L. monocytogenes Varja не виявлено гени actA та hly. За допомогою ПЛР встановлено також приналежність 11 досліджуваних культур до серотипів 4b, 4d, 4e, а також одного ізоляту до 1/2а. Отримані дані можуть бути використані для вдосконалення діагностики лістеріозів тварин в Україні за рахунок створення високоспецифічних антигенів
Ключові слова: лістеріоз, полімеразна ланцюгова реакція, фактори вірулентності
