Borrelia burgdorferi sensu lato (s.l.) causes the most common tick-borne infection in Europe, with Germany being amongst the countries with the highest incidences in humans. This study aimed at (1) comparing infection rates of B. burgdorferi s.l. in questing Ixodes ricinus ticks from different habitat types in Southern Germany, (2) analysing genospecies distribution by habitat type, and (3) testing tissue and ticks from hosts for B. burgdorferi s.l. Questing ticks from urban, pasture, and natural habitats together with feeding ticks from cattle (pasture) and ticks and tissue samples from wild boars and roe deer (natural site) were tested by PCR and RFLP for species differentiation. B. burgdorferi s.l. was found in 29.8% questing adults and 15% nymphs. Prevalence was lower at the urban sites with occurrence of roe deer than where these were absent. Borrelia burgdorferi s.l. DNA was found in 4.8% ticks from roe deer, 6.3% from wild boar, and 7.8% from cattle. Six genospecies were identified in unfed ticks: Borrelia afzelii (48.6%), Borrelia burgdorferi sensu stricto (16%), Borrelia garinii (13.2%), Borrelia valaisiana (7.5%), Borrelia spielmanii (6.2%), and Borrelia bavariensis (0.9%). This study shows high infection levels and a great diversity of Borrelia in questing ticks. The presence of roe deer seems to reduce B. burgdorferi s.l. infection rates in tick populations.

Tick Vectors

Abstract Lyme and other tick-borne diseases are increasing in the eastern United States and there is a lack of research on integrated strategies to control tick vectors. Here we present results of a study on tick-borne pathogens detected from tick vectors and rodent reservoirs from an ongoing 5-yr tick suppression study in the Lyme disease-endemic state of Maryland, where human-biting tick species, including Ixodes scapularis Say (Acari: Ixodidae) (the primary vector of Lyme disease spirochetes), are abundant. During the 2017 tick season, we collected 207 questing ticks and 602 ticks recovered from 327 mice (Peromyscus spp. (Rodentia: Cricetidae)), together with blood and ear tissue from the mice, at seven suburban parks in Howard County. Ticks were selectively tested for the presence of the causative agents of Lyme disease (Borrelia burgdorferi sensu lato [s.l.]), anaplasmosis (Anaplasma phagocytophilum), babesiosis (Babesia microti), ehrlichiosis (Ehrlichia ewingii, Ehrlichia chaffeensis, and ‘Panola Mountain’ Ehrlichia) and spotted fever group rickettsiosis (Rickettsia spp.). Peromyscus ear tissue and blood samples were tested for Bo. burgdorferi sensu stricto (s.s), A. phagocytophilum, Ba. microti, and Borrelia miyamotoi. We found 13.6% (15/110) of questing I. scapularis nymphs to be Bo. burgdorferi s.l. positive and 1.8% (2/110) were A. phagocytophilum positive among all sites. Borrelia burgdorferi s.s. was found in 71.1% (54/76) of I. scapularis nymphs removed from mice and 58.8% (194/330) of captured mice. Results from study on tick abundance and pathogen infection status in questing ticks, rodent reservoirs, and ticks feeding on Peromyscus spp. will aid efficacy evaluation of the integrated tick management measures being implemented.

Birds are increasingly considered important in the  global dispersal of tick-borne pathogens. The purpose of this study was to investigate the prevalence of Borrelia burgdorferi sensu lato genospecies in Ixodes ricinus ticks collected on passerine birds from two ornithological stations (Jomfruland and Lista) in southern Norway. In both sampling sites a total of 608 (109 larvae and 499 nymphs) of immature ticks were collected from 157 infested birds representing 26 species. The presence of B. burgdorferi s.l. DNA in ticks was tested using direct PCR amplification of the ospA gene, localized on lp-54 plasmid in B. burgdorferi s.l. genome. Twenty one out of 157 infested (13%) birds carried B. burgdorferi s.l. infected Ixodes ricinus ticks. B. burgdorferi s.l. DNA was detected in 19.7% of the tick samples. In total, 6.4% of larvae (7/109) and 10% of nymphs (50/499) were positive. The vast majority of infected ticks were found on blackbird (Turdus merula). The most frequent genospecies was B. garinii (85.5%), followed by B. afzelii (9.0%) and B. valaisiana (5.5%). Five different B. garinii genotypes were identified. Our findings showed that the blackbirds may support the circulation and spread of B. garinii and B. valaisiana. B. garinii was not detected in questing ticks from investigated locations. B. afzelii genospecies, however, dominated in questing ticks, rodents and ticks from rodents.

Changes in forest areas into agricultural areas and settlements cause the loss of some natural habitats, thus threatening the sustainability of the Javanese Lutung population. One of the Javanese Lutung habitats, Meru Betiri National Park. The purpose of this study was to determine the estimated population of Javanese Lutung and Javanese Lutung habitat characteristics in the Bandealit Resort of Meru Betiri National Park. Habitat characteristics were obtained through analysis of vegetation data, environmental data, and data on feed types by calculating the Important Value Index (INP) and its relation to environmental conditions in each habitat type. Population differences and habitat characteristics in each habitat type are obtained through Analysis of Variance (Anova) using SPSS (Statictical Program for Social Science) software. The results showed that the estimated population of Javanese Lutung in Meru Betiri National Park was 104 individuals found in 11 groups in all habitat types where each group consisted of 6-18 individuals. Components that have a real influence on each habitat type are temperature and humidity.

Fifteen Borrelia burgdorferi sensu lato isolates from questing ticks and skin biopsy specimens from erythema migrans patients in three different areas of Spain were characterized. Four different genospecies were found (nine Borrelia garinii, including the two human isolates, three B. burgdorferi sensu stricto, two B. valaisiana, and one B. lusitaniae), showing a diverse spectrum of B. burgdorferi sensu lato species. B. garinii isolates were highly variable in terms of pulsed-field gel electrophoresis pattern and OspA serotype, with four of the seven serotypes described. One of the human isolates was OspA serotype 5, the same found in four of seven tick isolates. The second human isolate was OspA serotype 3, which was not present in ticks from the same area. Seven B. garinii isolates were able to disseminate through the skin of C3H/HeN mice and to cause severe inflammation of joints. One of the two B. valaisianaisolates also caused disease in mice. Only one B. burgdorferi sensu stricto isolate was recovered from the urinary bladder. One isolate each of B. valaisiana and B. lusitaniae were not able to disseminate through the skin of mice or to infect internal organs. In summary, there is substantial diversity in the species and in the pathogenicity of B. burgdorferi sensu lato in areas in northern Spain where Lyme disease is endemic.
