Abstract


In Romania, it is necessary to collect recent data on the prevalence of swine cysticercosis, to detect areas of high endemicity and zoonotic risk, to prevent economic losses through proper implementation of control programs. A retrospective epidemiological study was performed during the period 2009-2013, by accessing report/surveillance systems and management of infected animals by analyzing the temporal and spatial distribution of swine cysticercosis in Romania. The study was conducted on the reporting of cases confirmed after the macroscopic exam in slaughterhouses after slaughtering the animals, in accordance to the national epidemio-surveillance strategic program for swine cysticercosis.In term of spatial spread, outbreaks were discovered in 7 countries (16.66%) of the 42 existing in Romania. During the studied period there were a total of 10 disease outbreaks. In term of temporal spread, cases of disease had been recorded every year taken under study. Links between the same different outbreaks, exist in the same year or in successive years, so we can see evolution trend of infection in the north-west of Romania, where there were discovered five of seven outbreaks.Analyzing the maintaining/recurrence of infection in outbreaks, we can mention Alba country, located in the north-west of the country, where the infestation was maintained 4 years (2009, 2010, 2012, 2013). In Cluj, the results obtained were correlated with T. solium infestation in humans by eating pork. The obtained results demonstrated that the control programs currently applied are not sufficient to diminuate and/or eradicate these diseases in Romania. Serological surveillance and molecular diagnostic tests are mandatory to be introduced, besides the slaughterhouse basic exams.
