- Tick Study Reveals Species Distribution and Pathogen Prevalence in Hungary
A complete study conducted in Hungary has shed light on the distribution of tick species infesting humans and the prevalence of pathogens they carry. The research, which analyzed 502 ticks, primarily from Hungary but also from patients who had traveled from other European countries, revealed that Ixodes ricinus is the predominant species, accounting for 92.8% of the collected ticks. This finding underscores the importance of understanding the risks associated with tick bites in the region, especially given the increasing incidence of tick-borne diseases across Europe.
Dominant Tick Species and Their Distribution
The study identified six ixodid tick species. After Ixodes ricinus, the most common were Dermacentor reticulatus (4.4%), Dermacentor marginatus (1.8%), Ixodes hexagonus (0.4%), and haemaphysalis concinna (0.4%), with a single finding of A. inermis (0.2%). Nymphs represented the majority (67%) of I. ricinus specimens, while larvae had the lowest ratio (4.3%).

The geographical distribution of ticks is influenced by climate change, leading to the expansion of tick habitats and increased risk of tick-borne diseases in previously unaffected areas Centers for disease Control and Prevention.
Pathogen Prevalence in Ticks
28.7% of the ticks analyzed contained pathogen DNA. A higher proportion of Dermacentor spp. (38.7%) were infected compared to I.ricinus (28.1%). Multiple pathogens were found only in I. ricinus specimens. Borrelia burgdorferi s. l. was detected in 15.2% of I. ricinus ticks, followed by Rickettsia helvetica (8.2%), A. phagocytophilum (3.9%), and other pathogens at lower rates.
Pro Tip: When removing a tick, use fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible.
Borrelia Genospecies Distribution
among the borrelia burgdorferi s. l. complex, seven genospecies were identified. Borrelia afzelii was the most prevalent (70.7%), followed by Borrelia garinii (8%), Borrelia lusitaniae (6.7%), and other species at lower frequencies.
Tick Exposure Locations and Seasonality
The majority of patients (44.6%) reported tick exposure in their own or a relative’s garden, while only 15.9% mentioned an excursion. D. marginatus and D. reticulatus were most frequently collected in April and May, respectively. I. ricinus nymphs peaked in May, females in May and June, and larvae in July.
Seasonal Activity of Ticks
Understanding the seasonal activity of different tick species is crucial for implementing targeted prevention strategies. The peak activity periods for each species and developmental stage can inform public health campaigns and personal protective measures.
Tick Engorgement and erythema migrans
Ticks removed from patients presenting with erythema migrans (EM), a hallmark symptom of Lyme disease, were significantly more likely to be at least slightly engorged (35%) compared to unengorged ticks (13.3%). The ratio of ticks from EM-diagnosed patients increased further in the categories of moderately fed ticks (45%) and fully engorged ticks (49%).
The correlation between tick engorgement and EM suggests that longer attachment times increase the likelihood of pathogen transmission. Prompt tick removal is thus essential in preventing Lyme disease and other tick-borne illnesses.
Key Findings Summarized
| Tick Species | Prevalence | Peak Activity | Common Pathogens |
|---|---|---|---|
| Ixodes ricinus | 92.8% | Nymphs: May; Females: May-June; Larvae: July | Borrelia burgdorferi s. l., Rickettsia helvetica |
| Dermacentor reticulatus | 4.4% | May | Rickettsia raoultii |
| Dermacentor marginatus | 1.8% | April | rickettsia raoultii |
evergreen Insights on Tick-Borne Diseases
Tick-borne diseases are a growing public health concern worldwide. Factors such as climate change, deforestation, and increased human-wildlife interaction contribute to the spread of ticks and the pathogens they carry. Lyme disease, caused by Borrelia burgdorferi, is the most common tick-borne disease in the Northern Hemisphere, but other diseases such as anaplasmosis, babesiosis, and Rocky Mountain spotted fever are also significant threats national Institute of Allergy and Infectious Diseases.
Preventive measures, including wearing protective clothing, using insect repellents, and performing thorough tick checks after outdoor activities, are crucial in reducing the risk of tick bites and subsequent disease transmission. Early diagnosis and treatment are essential for managing tick-borne illnesses and preventing long-term complications.
Frequently Asked Questions About Ticks
- what are the symptoms of Lyme disease?
- Symptoms of Lyme disease can include a bullseye rash (erythema migrans), fever, fatigue, headache, and muscle aches. if left untreated,Lyme disease can lead to more severe symptoms affecting the joints,heart,and nervous system.
- How can I protect myself from tick bites?
- To protect yourself from tick bites, wear long sleeves and pants when in wooded or grassy areas, use insect repellent containing DEET, and perform thorough tick checks after spending time outdoors.
- What should I do if I find a tick on my body?
- If you find a tick on your body, remove it promptly using fine-tipped tweezers. Grasp the tick as close to the skin’s surface as possible and pull upward with steady, even pressure. Clean the area with soap and water.
- Are all ticks infected with pathogens?
- No, not all ticks are infected with pathogens. However, it is important to take precautions to avoid tick bites and to monitor for symptoms of tick-borne diseases if you are bitten.
- When is tick season?
- Tick season typically runs from spring through fall,with peak activity varying depending on the tick species and geographic location. Though, ticks can be active year-round in some areas.
