Sixty-eight Holstein calves with an average age of 17 days were randomly divided into four groups.

Research into the role of bird species in the feeding of &lt;em&gt;Ixodes ricinus&lt;/em&gt; ticks, the primary tick species of veterinary and public health importance in Europe, remains scarce. This study endeavors to bridge these knowledge gaps by (i) assessing the density of feeding ticks (&lt;span&gt;&lt;math&gt;&lt;mrow&gt;&lt;mi&gt;D&lt;/mi&gt;&lt;mi&gt;F&lt;/mi&gt;&lt;mi&gt;T&lt;/mi&gt;&lt;/mrow&gt;&lt;/math&gt;&lt;/span&gt;) within a bird community to pinpoint species making substantial contributions, and (ii) exploring interannual variations in &lt;span&gt;&lt;math&gt;&lt;mrow&gt;&lt;mi&gt;D&lt;/mi&gt;&lt;mi&gt;F&lt;/mi&gt;&lt;mi&gt;T&lt;/mi&gt;&lt;/mrow&gt;&lt;/math&gt;&lt;/span&gt; over an extended timeline. Furthermore, we investigate whether variations in individual tick burden (&lt;span&gt;&lt;math&gt;&lt;mrow&gt;&lt;mi&gt;T&lt;/mi&gt;&lt;mi&gt;B&lt;/mi&gt;&lt;mo&gt;)&lt;/mo&gt;&lt;/mrow&gt;&lt;/math&gt;&lt;/span&gt; were more closely associated with the characteristics of bird species or interannual variations affecting the density of questing tick, using interannual &lt;span&gt;&lt;math&gt;&lt;mrow&gt;&lt;mi&gt;T&lt;/mi&gt;&lt;mi&gt;B&lt;/mi&gt;&lt;/mrow&gt;&lt;/math&gt;&lt;/span&gt; variation as a surrogate. To fulfill these aims, we conducted a 13-year longitudinal study monitoring &lt;em&gt;I. ricinus&lt;/em&gt; ticks feeding on a bird community in a periurban forest in France, covering breeding periods from 2007 to 2019. Within this community, we identified seven principal bird species significantly contributing to &lt;em&gt;I. ricinus&lt;/em&gt; tick feeding: the Common Blackbird (&lt;em&gt;Turdus merula&lt;/em&gt;), the Song Thrush (&lt;em&gt;Turdus philomelos&lt;/em&gt;), the European Robin (&lt;em&gt;Erithacus rubecula&lt;/em&gt;), the Dunnock (&lt;em&gt;Prunella modularis&lt;/em&gt;), the Eurasian Blackcap (&lt;em&gt;Sylvia atricapilla&lt;/em&gt;), the Great Tit (&lt;em&gt;Parus major&lt;/em&gt;), and the Common Nightingale (&lt;em&gt;Luscinia megarhynchos&lt;/em&gt;). Our results show that the bird community's contribution to tick feeding remained relatively consistent from year-to-year, though certain years displayed higher or lower &lt;span&gt;&lt;math&gt;&lt;mrow&gt;&lt;mi&gt;D&lt;/mi&gt;&lt;mi&gt;F&lt;/mi&gt;&lt;mi&gt;T&lt;/mi&gt;&lt;/mrow&gt;&lt;/math&gt;&lt;/span&gt; values related to the average over the study period.

Consequently, we emphasized the need to broaden the scope of future research on bird contributions to tick population dynamics beyond merely thrushes (&lt;em&gt;Turdidae&lt;/em&gt; species), to encompass a more diverse range of species, particularly those common birds that engage in ground foraging activities. Furthermore, variations in individual tick burden were predominantly influenced by the characteristics of bird species rather than by interannual variability in infestation rates. This finding suggests a significant role for species-specific traits in determining tick exposure and susceptibility.

In order to identify morphological characters unique to one of the monophyletic groupings within <em>Pavlovskyella</em> and improve its system, we describe all active stages of <em>Ornithodoros</em> (<em>Pavlovskyella</em>) <em>tartakovskyi</em>, a species with an incomplete original description. Larvae, nymphs, males and females from Iran were examined with scanning electron microscopy (SEM). The larva of <em>O</em>. (<em>P</em>.) <em>tartakovskyi</em> lacks dorsal plate, posteromedian seta, postcoxal setae and a spinose area in palpal article I; the dorsal surface has 13 pairs of setae and the hypostome has two short rows of denticles in the apex only. The first nymphal instar (N1) has a micromammillated body with faint dorsal and ventral disks. The second nymphal instar (N2) shows mammillated body with an incipient hood, and dorsal disks outlined as in subsequent instars. Both N1 and N2 have a small patch of glabrous surface in the anterior margin of preanal groove, absent in posterior stages. Third nymphal instar (N3) has a small hood and lack cheeks, which are incipient in the fourth nymphal instar (N4). The four nymphal instars (N1–N4) have blunt hypostomes, striated capitula, non-mammillated legs, and 3 humps on tarsi I. Females and males of <em>O</em>. (<em>P</em>.) <em>tartakovskyi</em> have mammillated bodies, small cheeks not covering the capitulum, the anteromedian disk is placed anteriorly to anterior central disks, and a posterior median file of disks is merged with the median disk. We describe all postembryonic stages of <em>O</em>. (<em>P</em>.) <em>tartakovskyi</em> providing morphological characters that define <em>Pavlovskyella</em> sensu stricto and <em>Theriodoros</em>, a sister subgenus that includes similarly shaped species.</p></div>","PeriodicalId":49320,"journal":{"name":"Ticks and Tick-borne Diseases","volume":"15 6","pages":"Article 102392"},"PeriodicalIF":3.1,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1877959X24000852/pdfft?md5=e12468f6ca080999dde6540829a3184a&pid=1-s2.0-S1877959X24000852-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142099673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To better understand the TBE surveillance landscape, online searches were conducted to determine if cases of TBE, TBEV infection, acute meningitis or encephalitis, or viral meningitis or encephalitis were subject to statutory reporting in European countries in 2023. In countries with statutory reporting, notification responsibility and available information on surveillance-reported cases were determined. The number of TBE cases reported to ECDC were compared with the number of cases recorded in national surveillance reports. Of 44 countries of the Europe Region of the United Nations, 37 (84 %) mandated statutory reporting of cases of TBE, TBEV infection, or acute/viral meningitis/encephalitis. Twenty-six (87 %) of 30 countries with identified surveillance reports recorded TBE cases in 2020–2023. Of these countries, 17 (65 %) required TBE reporting by clinicians and laboratories, 5 (19 %) by clinicians only, and 4 (15 %) by laboratories only. Twenty-four countries reported on TBE cases to ECDC in 2020; however, surveillance for TBE in Europe is heterogeneous.

We aimed to elucidate the factors that determine tick infestation in wild animals by investigating ticks on invasive raccoons (<em>Procyon lotor</em>) in Hokkaido, Japan. We first examined the composition, intensity, and seasonal variation of ticks infesting raccoons in six study areas in Hokkaido from March 2022 to August 2023. In one study area, ticks infesting tanukis (raccoon dog, <em>Nyctereutes procyonoides albus</em>) were collected in May to July in both 2022 and 2023, and questing ticks were collected from the vegetation by flagging every other week in the same period. Next, we screened 17 environmental and host variables to determine factors that affect the number of ticks infesting raccoons using generalized linear (mixed) models. From 245 raccoons, we identified a total of 3,917 ticks belonging to eight species of two genera: the most prominent species were <em>Ixodes ovatus</em> (52.9 %), followed by <em>Haemaphysalis megaspinosa</em> (14.4 %), <em>Ixodes tanuki</em> (10.6 %), and <em>Ixodes persulcatus</em> (9.5 %). <em>Ixodes ovatus</em> was also predominant among questing ticks and ticks infesting tanukis. Although <em>I. tanuki</em> was frequently collected from raccoons and tanukis, it was rarely collected in the field. The variables that significantly affected the infestation on raccoons differed by genus, species and developmental stage of the tick. For instance, the infestation of adult <em>I. ovatus</em> was significantly affected by four variables: night-time temperature during nine days before capturing the raccoon, the size of forest area around the capture site, sex of the raccoon, and sampling season. The first two variables were also responsible for the infestation on raccoons of almost all species and stages of ticks. Our study revealed that the number and composition of ticks infesting raccoons can be affected not only by landscape of their habitats but also by weather conditions in several days before capturing.</p></div>","PeriodicalId":49320,"journal":{"name":"Ticks and Tick-borne Diseases","volume":"15 6","pages":"Article 102389"},"PeriodicalIF":3.1,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1877959X24000827/pdfft?md5=226089a5050c1cc34cdd5de2d102a33b&pid=1-s2.0-S1877959X24000827-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141978602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
