From the journal Acta Parasitologica


Toxoplasma gondii, a coccidian parasite known to infect almost all warm-blooded animals, is the cause of one of the most common zoonotic parasitic diseases. The aim of the study is to determine whether the 529 bp fragment or the TGR1E gene is more useful target for PCR identification of T. gondii, for common use. The brains of 221 carnivores and omnivores collected between 2013 and 2015 from north-eastern Poland were examined for the presence of this parasite. The DNA was extracted and then amplified using specific primers. Positive results were obtained in 24% of brain samples using the TGR1E target and 19% using the 529 bp sequence. The results demonstrate that both TGR1E and 529 bp repeat element are suitable for detecting T. gondii DNA in wildlife animals, and the combination of two methods is necessary to obtain reliable results.
