Summary: The study found Borrelia burgdorferi s. l. positive ticks in all plots around Munich, Germany, with significantly different numbers of positive nymphs between plots but not for positive adults. Six Bbsl genospecies were identified, with B. afzelii and B. garinii dominating and B. miyamotoi found in two sampling plots, highlighting variability in Bbsl prevalence and genospecies distribution over short geographic distances.

Summary: The study demonstrates high infection levels and diverse genospecies of Borrelia in questing ticks in different habitats in Southern Germany. The presence of roe deer appears to reduce infection rates of B. burgdorferi s.l. in tick populations.

Summary: This study investigated the altitudinal distributions, population structures, and seasonal dynamics of tick fauna in three localities in Continental Croatia (Medvednica and Papuk) and an alpine biogeographic region (Gorski Kotar). Questing ticks were sampled twice a year (spring and autumn, from 2019 to 2021) at different altitudes using the flagging method. The majority of the ticks were identified as Ixodes ricinus, with the highest tick abundance observed at higher altitudes in mixed forests of European beech and European silver fir. Borrelia burgdorferi sensu lato infection was detected in a small percentage of ticks, with the presence of the Borrelia burgdorferi sensu stricto genotype.

Summary: This study established a nationwide database involving Lyme borreliosis risk factors in China and used a two-stage statistical model to identify the environmental factors influencing its distribution. By mapping the risk distribution, it was found that high-risk areas were not only concentrated in high latitude regions but also distributed in middle and low latitude areas.

Summary: In this study, the presence of B. burgdorferi s.l. in pet dogs and tick pools in the Lahore City Metropolitan Area, Pakistan was investigated. It was found that a certain percentage of dogs and tick pools tested positive for B. burgdorferi s.l. Through phylogenetic analysis, the sequences were clustered with B. burgdorferi sensu stricto, B. bavariensis, B. garinii, and B. bissettii sequences from different hosts worldwide. Statistical analysis revealed significant associations between certain animal-related and management-related factors and occurrence of Lyme borreliosis.

Summary: This study found that apparent Bbsl seroconversion often occurs in patients receiving IVIg treatment, but antibodies typically disappear post-treatment, with seroreversion observed in a majority of patients within 3 months. The transient presence of anti-Bbsl IgG antibodies after IVIg treatment appears to be dependent on the brand of IVIg, reflecting variations in Bbsl exposure of plasma donors. Lyme borreliosis serological testing during and after IVIg treatment may be of limited utility.

Summary: In Poland, tick-borne diseases, especially Lyme borreliosis, are the majority of diseases caused by exposure to biological agents, so studying ticks as reservoirs of various pathogens is crucial for understanding the epidemiology of these diseases. This study investigated the occurrence of several pathogens, including Borrelia burgdorferi sensu lato, Borrelia miyamotoi, Neoehrlichia mikurensis, and Babesia spp., in ticks collected from vegetation in eastern Poland. The study also found that co-infections with multiple pathogens are relatively common in adult Ixodes ricinus ticks. The findings highlight the importance of monitoring tick-borne pathogens for human health risk assessment.

Summary: The aim of this study was to identify the molecular characteristics of Borrelia burgdorferi sensu lato and Bartonella spp. pathogens detected in Lipoptena spp. The overall prevalence of B. burgdorferi s.l. DNA in Lipoptena cervi was 14.04%, and the overall prevalence of Bartonella spp. was 57.02%.

Summary: The interaction between hosts and ticks plays a crucial role in the ecology of vector-borne diseases, with birds potentially playing a role in the maintenance and dispersal of Borrelia burgdorferi s.s., the main causative agent of Lyme disease in the southeastern United States.

Summary: Lyme borreliosis is common in Kazakhstan, especially in the Almaty oblast, with evidence of active circulation of Borrelia burgdorferi s.l. The study found a 24% prevalence rate of B. burgdorferi s.l. in Ixodes persulcatus ticks that attacked humans, as well as a 5.8% seroprevalence rate of antibodies against B. burgdorferi s.l. in the local population. These results highlight the importance of LB preventive measures in the region.
