Even though thedisease is a serious public health concern, only a limited number of Trichinella isolates havebeen identified at the species level; in the past, all larvae were assumed to be Trichinellaspiralis. The present study was conducted to identify Trichinella spp. circulating amongwild and domestic animals in Romania, using PCR-based methods. Trichinella spp. larvaeoriginating from 54 wild and 23 domestic mammals were examined. No Trichinella spp.larvae were detected in muscle samples of 182 birds. T. spiralis and Trichinella britovi werethe only two species identified in the 40 isolates that yielded a positive PCR result. Overall,T. britovi was more prevalent (n = 26; 65%) than T. spiralis (n = 14; 35%). T. spiralis was thepredominant species found in domestic animals (n = 9; 75%), while T. britovi was moreprevalent in wildlife (n = 24; 86%). No mixed infections were found. The highestprevalence of Trichinella infection was detected in wolves (11/35; 31%), in European wildcats (4/28; 14%), and in red foxes (5/71; 7%). The distribution of Trichinella spp. in Romaniadoes not show a species-specific clustering; both of the two species found were presentover the entire range of counties studied.
