Detection of protozoans Babesia microti and [i]Toxoplasma gondii[/i] and their co-existence in ticks (Acari: Ixodida) collected in Tarnogórski district (Upper Silesia, Poland)
Journal Title: Annals of Agricultural and Environmental Medicine - Year 2015, Vol 22, Issue 1
Abstract
[b]Introduction[/b]. Ticks (Acari: Ixodida) are vectors of many pathogens i. a: [i]Babesia microti [/i][Bm] and [i]Toxoplasma gondii[/i] [Tg]. In Poland, Ixodes ricinus [Ir] is the main vector of both pathogens. This tick species and pathogens transmitted by them are a significant threat to human and animal health. objectives of the study. Detection of the protozoans Bm and Tg in ticks collected in the Tarnogórski district area. [b]Material and methods[/b]. The ticks were collected from vegetation and pets in the spring period of their activity on the territory of the Tarnogórski district. The parasites were preserved in 70% ethanol. DNA was isolated by ammonia method. Bm was detected by nested-PCR using specific primers for the 18S rRNA sequence. To detect the Tg a commercial kit was used. The PCR products were separated on 2% ethidium bromide stained agarose gels and visualised under UV light. [b]Results[/b]. It was showed that all collected ticks belonged to the species Ir. Bm was detected in 50.87% and Tg in 64.91% of all examined ticks. Co-existence of these both protozoans in 36.84% of total examined ticks was noted. [b]Conclusions[/b]. The study showed a high risk of exposure to Bm and Tg in the studied area. Ticks Ir play an important role in the transmission of Bm in this region. Demonstrating a high percentage of ticks collected from animals infected with Tg may indicate their important role in the transmission of this pathogen, but it requires a further studies.
