Effects of a standardized natural yeast-thiamine-complex in 34 dogs with tick infestation

Ticks play an essential role in the spread of vector-borne diseases herefore tick control becomes even more important [1]. The resistance of ticks, climatic changes with long-term effects, as well as increasing global movement of animals and goods have favored development and spread of ticks and their diseases [2]. The aim of this study was to investigate the effects of the natural yeast-thiamine-complex (Formel-Z^®) in dogs with tick infestation within a one-year tick season.

he average amount of free and attached ticks was counted before and after the beginning of daily administration of the natural complex (167.85 mg/kg bw/day the product specification). A total of 34 dogs of different breed (with fur of moderate hair length) included in study based on a dog-owner questionnaire.

The number of free ticks on the animals was significant reduced by 74.43% (M±SD before feeding: 2.84±2.06, M±SD after feeding: 0.73±0.45) after the administration of the standardized yeast-thiamine-complex. the number of attached ticks showed a decrease (M±SD before feeding: 2.13±1.93, M±SD after feeding: 0.69±0.51) by 67.62%. In addition, none of the dog-owners noticed an increase in dead ticks, while some of them reported a visible improvement of fur and skin properties of their animals.

In conclusion, the results provide a first evidence for the efficacy of a standardized natural yeast-thiamine-complex for the prevention of tick infestation through a potential repellent effect. Thus, the standardized natural product a good to reduce tick infestation.
