Lyme disease: The great imitator

Abstract

Lyme disease, or Lyme borreliosis can occur in domestic animals and in people, with no characteristic symptoms. That is why Lyme disease is often diagnosed and treated as some other disease. Clinical symptoms of this disease are not specific and they can look like a number of different diseases, which is why the disease is called -the great imitator. The reservoirs of the disease are ticks Ixodes ricinus. During the research from 2005 to 2007 it was established that the prevalence with Lyme borreliosis exists within the tick population.The objective of this paper is a survey of the presence of Lyme disease in different populations of different animal species (horses, cattle, sheep and dogs) in the region where the infection of ticks with Borrelia burgdorferi was established in the percentage of 25-28%.The methods used were the ones for the determination of Borrelia burgdorferi in ticks, with a dark field microscopy, and also the presence of antibodies against Borrelia burgdorferi was determinated with a complement fixation reaction, in the blood sera of horses, sheep, cattle and dogs.As the result it was found that the cause of Lyme disease, Borrelia burgdorferi is constantly present within the tick population. In examined horses and cattle the presence of antibodies against B. burgdorferi was not found, while in sheep and dogs, the presence of antibodies was found.Any seropositive animal, and also an infected tick, represents a danger for the human population and also for other animals, which are in the surrounding. Lyme disease is usually not mortal, but it can create a lot of problems leading to the decrease of production in domestic animals or an illness with clinical symptoms in humans, horses and dogs.

Seasonal Dynamics and Physiological Age of Ixodid Ticks Collected from Dogs

“…Knowing the tick seasonal dynamics is extremely important, since the potential risk for humans and accompanying animals to encounter ticks could be assessed and, consequently, the possible occurrence of TBD prevented. Increased abundance and appearance of ticks in certain habitats, as well as their questing activity for adequate hosts coincide with increased human and accompanying dogs' activity in nature (sports, recreation, hunting, vacation, dog exhibitions) [46]. Our results demonstrated similar seasonal patterns in ticks found attached to dogs with those described for ticks collected from nature, especially for I. ricinus and two Dermacentor species.…”
