The peculiarities of prevention of diphylobotriosis on the Lena river

For the purpose of clarification of epidemiological role of some fish products and the ways of their processing by local population the observations over preparation of fish soup by fishermen, baking of pies, pickles and freezing of omul were made. Fish soup cooked until the fish was well done, and fish pies were not the factors of the transmission of diphyllobothriasis to the man. In locally salted tuguns and pikes in a ratio of salt to fish of 0.6:10, plerocercoids in the former remain alive for up to 5-6 days, and for large fish - up to 7 days. Complete neutralization of fish in freezers was observed at the temperature of minus 18 °C after 13 or more hours and at the temperature of minus 10-12 °C for 48 hours. Omul and other types of ice fishing, frozen naturally, did not become the cause of any epidemiological problem in the conditions of Yakutia. The effectiveness of azinoxgiven orally as pills in a dose of active substance of 5 mg/kg of live weight in individual treatment of dogs and cats and phenasal in a dose of 150 mg/kg - for dogs against diphyllobothriasis was 100 % according to the intensity and extraspecific indicators. Febtal at a dose of 10 mg/kg of live weight in individual treatment of dogs was not very effective for diphyllobothriasis, extensive efficiency was 50.0 %, and intensive efficiency - 66.7 %. The need for anthelmintic measures was dictated by the danger of diphyllobothriasis for the health of the people, leading to prolonged disability, and sometimes death. A seriously ill person for 10 years can spread a huge number of eggs of a wide ribbon to the environment. Carnivores and birds, although to a lesser extent than the man, are also distributors of diphyllobotriid eggs. The fight against diphyllobothriasis of the man, animals and birds in the Russian Federation aimed at breaking epidemiological and epizootological chains is a medical, veterinary, social and economic task.
