The lone star tick (LST), Amblyomma americanum, is an aggressive human biter and important vector of the causative agents of tick-borne diseases. As geographic ranges of multiple Amblyomma species rapidly expand due to habitat changes and human and other animal movement patterns, there are concerns for establishment of LST in US states with suitable climates, such as California, especially given a dearth in gaps in tick surveillance. Importantly, previous niche modeling confirmed habitat in California along the length of the coast and coast range mountains. We sought data on LSTs and LST risk from 30 different entities including companies that identify and test ticks, natural history and entomology museums and collections, experts, and large databases. These queries and published records yielded records of 76 LSTs from California as well as two Amblyomma cajennense sensu lato, one Amblyomma sabanerae, one Amblyomma maculatum, and five Amblyomma dissimile. Among LSTs, there were 18 adult females, ten males, 13 adults for which sex was not recorded, 22 nymphs, two larvae, and 11 with no stage data. LSTs were recorded only during late spring through late summer, with all three feeding stages superimposed temporally. Active surveillance was conducted at nine sites considered high-risk due to earlier records of LSTs or high probability of establishment on niche modeling, using tick flagging, monitoring ovine and cervid hosts, and circulating a flier; no LSTs were recovered in this activity. We assessed risk for establishment of LSTs in California using invasion theory, prior niche modeling, literature review of ecological constraints on LSTs within their current range, data acquired in retrospective and prospective segments of this study, and expert consultation. Elevated risk is expected particularly along coastal California. Although some of these ticks likely were transported from out of state endemic regions, the findings of 76 LSTs, including all three feeding stages, in multiple counties raises concern that establishment in the future could occur in California.

孤星蜱（Amblyomma americanum）是一种具有攻击性的人类叮咬者，是蜱传疾病病原体的重要媒介。由于栖息地的变化以及人类和其他动物的运动模式，多种蜱虫物种的地理范围迅速扩大，人们担心在美国气候适宜的州（如加利福尼亚州）建立LST，特别是考虑到蜱虫监测方面的不足。重要的是，之前的生态位模型证实了加州沿海岸和海岸山脉的栖息地。我们从30个不同的实体中寻找LST和LST风险的数据，包括鉴定和测试蜱虫的公司、自然历史和昆虫学博物馆和收藏、专家和大型数据库。这些查询和已发表的记录产生了76个来自加利福尼亚的lst记录，以及2个camjenense sensu lato Amblyomma sabanerae， 1个maculatum Amblyomma maculatum和5个disdism Amblyomma。其中雌成虫18只，雄成虫10只，未记录性别的成虫13只，若虫22只，幼虫2只，无龄期记录11只。lst仅在春末至夏末记录，所有三个摄食阶段在时间上重叠。在9个被认为高风险的地点进行了主动监测，因为早期有lst记录或建立生态位模型的可能性很大，使用蜱虫标记，监测羊和宫颈宿主，并散发传单；本次活动未回收lst。我们利用入侵理论、先前的生态位模型、对当前范围内lst的生态约束的文献综述、本研究的回顾性和前瞻性部分获得的数据以及专家咨询来评估在加州建立lst的风险。预计加州沿海地区的风险会增加。尽管其中一些蜱虫可能是从州外的流行地区运来的，但在多个县对76个lst（包括所有三个喂养阶段）的调查结果引起了人们的担忧，即未来可能会在加州建立。

Lyme borreliosis (LB), caused by Borrelia burgdorferi sensu lato (Bbsl), is a significant public health concern in Switzerland. Reliable data on seroprevalence and incidence are needed to better understand disease burden and inform prevention strategies. This study aimed to estimate the seroprevalence of Bbsl-specific antibodies and the incidence of symptomatic LB infections in the Swiss adult population.

We analyzed Bbsl-specific IgG antibodies in 2,194 residual plasma samples from blood donors (aged 18–75 years) collected at seven Swiss Red Cross donation centers between September and December 2022. Samples were tested using the Liaison® Borrelia IgG VlsE chemiluminescence immunoassay and confirmed with the SeraSpot Anti-Borrelia-10 IgG assay according to National Reference Laboratory interpretative criteria.

The overall seroprevalence was 6.1%, with higher prevalence in males (8.2%) than in females (2.9%) and regional variation ranging from 1.6% in Genève to 8.8% in Bern. Based on seroprevalence data, the estimated incidence of symptomatic Bbsl infections was 224 cases per 100,000 population per year (PPY). This estimate, although 1.3 times higher, is similar to the incidence derived from the Sentinella surveillance network. Using Sentinella data, clinically diagnosed erythema migrans was the most common manifestation (150 cases per 100,000 PPY), while disseminated forms, confirmed by clinical and laboratory criteria, occurred less frequently (1.0–8.5 cases per 100,000 PPY).

Our findings provide critical insights into the burden of LB in Switzerland, highlight its public health relevance, and reinforce the importance of preventive measures. Future research should focus on longitudinal monitoring and harmonized methodologies to facilitate cross-country comparisons.

莱姆性伯氏疏螺旋体（Borrelia burgdorferi sensus lato, Bbsl）引起的莱姆性伯氏疏螺旋体病（Lyme borrelii， LB）是瑞士的一个重大公共卫生问题。需要关于血清患病率和发病率的可靠数据，以便更好地了解疾病负担并为预防战略提供信息。本研究旨在估计瑞士成年人群中bsl特异性抗体的血清患病率和症状性LB感染的发生率。我们分析了2022年9月至12月期间在七个瑞士红十字会捐赠中心收集的2194份献血者（18-75岁）残留血浆样本中的bbsl特异性IgG抗体。采用Liaison®伯氏疏螺旋体IgG VlsE化学发光免疫分析法对样品进行检测，并根据国家参考实验室解释标准用SeraSpot抗伯氏疏螺旋体-10 IgG测定法进行确认。总体血清患病率为6.1%，男性患病率（8.2%）高于女性（2.9%），区域差异从gen区的1.6%到伯尔尼的8.8%不等。根据血清流行率数据，估计有症状的Bbsl感染发生率为每年每10万人224例（PPY）。这一估计虽然高出1.3倍，但与从Sentinella监测网得出的发病率相似。根据Sentinella数据，临床诊断的移行性红斑是最常见的表现（150例/ 100,000 PPY），而经临床和实验室标准证实的弥散性红斑发生频率较低（1.0-8.5例/ 100,000 PPY）。我们的研究结果对瑞士的LB负担提供了重要的见解，强调了其公共卫生相关性，并强调了预防措施的重要性。今后的研究应侧重于纵向监测和统一的方法，以促进跨国比较。

The tick fauna in Cambodia is poorly documented, with limited information on the diversity and distribution of tick species. This study aimed to address this knowledge gap by investigating tick species collected from various hosts, and across different habitats and regions of the country. Tick sampling was conducted in urban areas, rural villages, farms, and forest fringes, with additional samples obtained from a wildlife rescue center, caves, and swiftlet nests. Ticks were collected directly from hosts, as well as on vegetation through flagging methods. Tick species were identified morphologically, and selected specimens were subjected to molecular identification using the cox1 gene. A total of 853 vertebrate hosts representing 13 different animals, including five wildlife, were inspected: buffalo, cats, cattle, chickens, dogs, ducks, goats, goose, pigs, pigeons, pangolins, pythons, and wild pigs. From this first nationwide tick collection, a total of 7,461 ticks were collected, comprising six genera and 14 species of ticks, including seven newly identified species such as Carios batuensis, Dermacentor steini, Dermacentor filippovae, Haemaphysalis canestrinii, Haemaphysalis formosensis, Haemaphysalis hystricis, and Haemaphysalis wellingtoni. Rhipicephalus microplus and Rhipicephalus linnaei were the most predominant tick species collected from cattle and dogs, respectively, whereas no ticks were found on buffaloes, chickens, ducks, goose, pigs or pigeons. Results showed that ticks are widely distributed throughout Cambodia, with particularly rich diversity observed in forest fringes habitats. This study also allowed the number of tick species identified in the country with seven additional species, bringing the total to 26.

柬埔寨的蜱动物群文献很少，关于蜱物种多样性和分布的信息有限。本研究旨在通过调查从不同宿主、不同栖息地和不同地区收集的蜱虫物种来解决这一知识差距。在城市地区、农村、农场和森林边缘进行蜱虫取样，并从野生动物救援中心、洞穴和金丝燕巢穴中获得额外样本。蜱虫直接从寄主身上采集，也可通过标记法在植被上采集。对蜱类进行形态学鉴定，并选取样本进行cox1基因分子鉴定。共有代表13种不同动物的853种脊椎动物宿主接受了检查，其中包括5种野生动物：水牛、猫、牛、鸡、狗、鸭、山羊、鹅、猪、鸽子、穿山甲、蟒蛇和野猪。首次在全国范围内采集蜱类，共采集到蜱类6属14种7,461只，其中新发现的蜱类有巴图金蜱、斯坦金蜱、菲律宾金蜱、canestrini血蜱、formosensis血蜱、hystricis血蜱和wellingtoni血蜱7种。牛和犬的蜱类分别以微头蜱和林奈头蜱为优势蜱种，水牛、鸡、鸭、鹅、猪和鸽子均未发现蜱类。结果表明，蜱虫在柬埔寨各地分布广泛，在森林边缘生境中尤其丰富。这项研究还使该国确定的蜱虫种类增加了7种，使总数达到26种。

While ecological factors drive tick abundance and pathogen prevalence, human behaviors and demographics can interact with these ecological drivers to shape tick encounter risk. We analyzed 7848 tick submissions and associated survey responses from Maine residents collected from January 2020 through December 2022 via a passive tick surveillance program. We examined the spatial and demographic differences in the use of tick prevention strategies among individuals who submitted tick specimens. We investigated differences in tick encounter frequency across reported property types and human activities and differences in tick attachment sites on the body, based upon human age and tick life stage. We found that personal protection measures were used prior to only 15 % of reported tick encounters, with higher usage reported for ticks found on adults than children and by individuals engaged in high-perceived-risk activities including camping, hunting, hiking, and agricultural work. We also detected spatial differences, with residents of southern regions that generally have higher acarological risk employing preventive measures more frequently than those in northern regions. Tick encounters were commonly reported at participants’ residences, often during yardwork/gardening and outdoor play. We noted age-related patterns in bite frequency and attachment sites, with children more frequently bitten on the head and neck and adults on the legs and torso. Across all age classes, immature ticks tended to attach lower on the body. By identifying high-risk areas, vulnerable age groups, predominant tick attachment sites, and gaps in protective practices, our findings can inform the development and implementation of targeted tick protection interventions.

虽然生态因素驱动蜱虫的丰度和病原体的流行，但人类的行为和人口统计学可以与这些生态驱动因素相互作用，形成蜱虫遭遇风险。我们分析了从2020年1月到2022年12月通过被动蜱虫监测计划收集的缅因州居民的7848份蜱虫意见书和相关调查回复。我们检查了提交蜱虫标本的个体在使用蜱虫预防策略方面的空间和人口差异。根据人类的年龄和蜱虫的生命阶段，我们调查了蜱虫接触频率在报告的财产类型和人类活动中的差异，以及蜱虫附着部位在身体上的差异。我们发现，在报告的蜱虫遭遇事件中，只有15%的人采取了个人保护措施，报告的蜱虫使用率高于儿童和从事高风险活动（包括露营、狩猎、徒步旅行和农业工作）的个人。我们还发现了空间差异，南方地区的居民通常比北方地区的居民更频繁地采取预防措施。蜱虫接触通常发生在参与者的住所，通常是在庭院/园艺和户外玩耍期间。我们注意到被咬的频率和附着部位与年龄有关，儿童更常被咬在头部和颈部，而成人更常被咬在腿部和躯干。在所有年龄段中，未成熟的蜱虫倾向于附着在身体的较低部位。通过确定高风险地区、脆弱年龄组、主要蜱虫附着地点和保护措施的差距，我们的研究结果可以为制定和实施有针对性的蜱虫保护干预措施提供信息。

Urban green spaces promote human well-being, but also represent areas of tick infestation and pathogen transmission risk. In Hanover city, Germany, long-term monitoring of questing tick abundance was initiated in 2017–2018 (Hauck et al., 2020). Here, we combine this data with a six-year follow-up, including the 2018–2020 and 2022 Europe-wide drought periods. Additionally, the density of infected nymphs (DIN) was calculated including pathogen prevalence data from 2020 (Glass et al., 2022). Tick density was observed to decline after drought years with a time lag, falling from an average of 25 and 26 ticks per 100 m² in 2017 and 2018 to 20 ticks in 2019, 16 in 2020 and 6 in 2021, which is a reduction of almost 75%. After the precipitation-rich year of 2021, density began to recover in 2022 (7 ticks/100 m²), but remained low in 2023 (10 ticks/100 m²) and 2024 (8 ticks/100 m²). After the 8-year observation period, tick density has therefore been reduced by almost 70% compared to initial values. Generalized linear mixed modelling showed significant associations between I. ricinus density and climatic variables. The DIN per monitoring site was 0.03–9.76/100 m², 0.00–0.04/100 m² and 0.11–16.81/100 m² for Borrelia spp., A. phagocytophilum, and Rickettsia species. This study strongly indicates that climate change, especially prolonged drought, affects I. ricinus populations in urban settings, and its long-term dataset can serve as a reference for future ecological and public-health risk assessments under a changing climate.

城市绿地促进了人类福祉，但也代表了蜱虫侵扰和病原体传播风险的区域。在德国汉诺威市，2017-2018年开始了对蜱虫丰度的长期监测（Hauck et al., 2020）。在这里，我们将这些数据与六年的随访相结合，包括2018-2020年和2022年欧洲范围内的干旱期。此外，还计算了感染若虫的密度（DIN），包括2020年的病原体患病率数据（Glass et al., 2022）。在干旱年份之后，蜱虫密度出现了时滞性下降，从2017年和2018年的平均每100平方米25和26只蜱降至2019年的20只、2020年的16只和2021年的6只，减少了近75%。经过2021年的丰水年，密度在2022年开始回升（7只/100 m²），但在2023年（10只/100 m²）和2024年（8只/100 m²）仍处于低位。因此，经过8年观察期后，蜱虫密度与初始值相比减少了近70%。广义线性混合模型显示蓖麻密度与气候变量之间存在显著关联。每个监测点伯氏疏螺旋体、嗜吞噬单胞杆菌和立克次体的DIN分别为0.03 ~ 9.76/100 m²、0.00 ~ 0.04/100 m²和0.11 ~ 16.81/100 m²。该研究强烈表明，气候变化，特别是长期干旱，会影响城市环境中的蓖麻种群，其长期数据集可作为未来气候变化下生态和公共卫生风险评估的参考。

Heartwater is a tick-borne disease caused by Ehrlichia ruminantium and remains endemic in the Guadeloupe archipelago. While previous data from 1989 suggested a seroprevalence of 22 % in cattle, no updated figures were available for livestock, and certain islands such as Les Saintes were considered disease-free.

This study aimed to update the sero-epidemiological status of heartwater in cattle and goats across Guadeloupe in 2024. Blood samples were collected from 261 cattle and 135 goats from all islands. Serological testing using the MAP1B ELISA was performed, and true seroprevalence was estimated using a simplified stochastic model that accounts for test sensitivity, specificity, and sample uncertainty. The mean cattle seroprevalence was estimated at 28 % (95 % CI [22–34 %]), with no significant differences between Basse-Terre, Grande-Terre, and Marie-Galante. Importantly, seropositive goats were identified on all major islands, including Les Saintes. Our findings suggest that heartwater remains endemically stable in Guadeloupe since the 1980s and reveal for the first time its serological presence in Les Saintes. These results emphasize the importance of strengthening regional surveillance systems, including veterinary reporting, serological monitoring, and coordinated efforts to prevent further spread across the Caribbean.

心水病是一种由反刍埃利希菌引起的蜱传疾病，在瓜德罗普群岛仍然流行。虽然1989年以前的数据表明牛的血清患病率为22%，但没有牲畜的最新数据，而且某些岛屿如Les Saintes被认为是无病的。本研究旨在更新2024年瓜德罗普岛牛和山羊心水的血清流行病学状况。从所有岛屿的261头牛和135头山羊中采集了血液样本。使用MAP1B ELISA进行血清学检测，并使用简化的随机模型估计真实血清阳性率，该模型考虑了检测敏感性、特异性和样本不确定性。牛的平均血清阳性率估计为28% (95% CI[22- 34%])，在Basse-Terre、Grande-Terre和Marie-Galante之间没有显著差异。重要的是，在包括Les Saintes岛在内的所有主要岛屿上都发现了血清阳性山羊。我们的研究结果表明，自20世纪80年代以来，心水在瓜德罗普岛保持地方性稳定，并首次揭示了其在Les Saintes的血清学存在。这些结果强调了加强区域监测系统的重要性，包括兽医报告、血清学监测和协调努力，以防止在加勒比地区进一步传播。
