The aim of the study was to determine the prevalence and the intensity of Echinococcus multilocularis invasion in red foxes (Vulpes vulpes) in the Lublin voivodeship, Poland, taking into consideration the localisation of these parasites in intestinal parties. The material for examination consisted of small intestines from foxes shot in the year 2007, free from rabies and derived from all 20 districts of the Lublin voivodeship. Samples were examined with the use of the sedimentation counting technique (SCT) modified for these study purposes. Each intestine was divided into 3 equal parts (anterior, medium, posterior) and each part was examined separately. Overall, intestines from 138 foxes were examined. E. multilocularis invasion was detected in 26 foxes (18.8%). Tapeworms were most frequently detected in the posterior part of the intestine (96.6% of invaded foxes). In the middle and anterior parts, E. multilocularis were detected in 76.9 and 57.7% of the invaded foxes respectively. The mean intensity of invasion was 612.3 tapeworms per fox. The intensity of invasion was significantly lower in the anterior part of the intestine in comparison to middle and posterior parts in which the intensity did not differ. Preliminary study showed a high percentage of foxes infected with E. multilocularis tapeworms in the Lublin voivodeship. The increasing prevalence of this parasite in foxes shows the growing danger from echinococcosis for inhabitants of this province. This is particularly essential in the situation when the population of foxes is increasing and changes of their behaviour are observed - among others, more frequent moving close to human settlements
The aim of the study was to determine the occurrence of Echinococcus multilocularis in red foxes in the Mazowieckie Voivodship. In the period of 2004-2006 the intestines of 379 red foxes were examined by intestinal scraping technique (IST) for the presence of Echinococcus multilocularis. From 2 -29 foxes were examined in each of the 36 counties amongst the 38 included in the voivodeship. 52 foxes were found to be infected (13.5%). The highest prevalence (11.8%-26.7%) was found in eight of the 36 counties. No differences in prevalence between sexes were observed. 66.7% of foxes were infected with low (1-100 tapeworms) and 27.5% with medium (101-1000) intensity. The prevalence found was much higher compared to that of earlier studies. The present results indicate the potential risk for human infection in central Poland, previously considered as being of very low endemic for E. multilocularis. Educational programs are vital in order to avert the potential threat of alveolar echinococcosis, particularly amongst risk groups (foresters, hunters, farmers) in hazardous areas
