This study investigates how mammal community composition and seasonality affect the abundance of questing ticks in mountainous forests of Gifu Prefecture, a border region of the SFTS endemic zone. Camera traps were used to monitor mammal species, and questing ticks were collected monthly via flagging along transects in 10 forest plots during 2021–2022. We recorded 14 mammal species including small-sized mammals like mice, medium-sized mammals like raccoon dog (<em>Nyctereutes viverrinus</em>), and large-sized mammals like wild boar (<em>Sus scrofa</em>). Among them, sika deer (<em>Cervus nippon</em>) was the most abundant. A total of 408 adult, 292 nymphal, and 1480 larval ticks representing 11 species (five <em>Haemaphysalis</em> species, five <em>Ixodes</em> species, and <em>Amblyomma testudinarium</em>) were collected. Generalized linear mixed models revealed that the abundance of adult <em>Haemaphysalis kitaokai</em> and <em>H. megaspinosa</em>, and nymphal <em>H. flava</em> and <em>H. megaspinosa</em> were significantly associated with sika deer abundance. Seasonal patterns varied by species and life stage, with <em>H. kitaokai</em> adults peaking in spring and early winter, and <em>H. megaspinosa</em> adults and nymphs in autumn. Wild boar abundance did not significantly influence tick numbers. These findings highlight the importance of sika deer as a key host driving tick population dynamics and underscore the role of host-targeted management, particularly deer population control, as a potential strategy to reduce tick density and related disease risks. Long-term monitoring is essential given ongoing climate and land-use changes that may alter tick phenology and distribution. Our results contribute to region-specific understanding of tick ecology and support the development of effective, ecologically informed countermeasures against tick-borne diseases in Japan.</div></div>","PeriodicalId":54278,"journal":{"name":"International Journal for Parasitology-Parasites and Wildlife","volume":"28 ","pages":"Article 101120"},"PeriodicalIF":2.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From July 2022–November 2024, 19 suspected mange (i.e., alopecia and crusty lesions) cases were identified in 16 eastern cottontail rabbits (<em>Sylvilagus floridanus</em>), an eastern gray squirrel (<em>Sciurus carolinensis</em>), a marsh rabbit (<em>Sylvilagus palustris</em>), and a northern raccoon (<em>Procyon lotor</em>) in Florida. Most were in poor nutritional condition with multifocal alopecia and hyperkeratosis. Histologically, mites were noted in the variably hyperkeratotic stratum corneum with associated serocellular crusts and epidermal hyperplasia. Mites from rabbits and the squirrel were identified as <em>Notoedres centrifera</em> and the raccoon was infested with <em>Notoedres cati</em>. ITS-2 sequences from the squirrel and 11 cottontail rabbits were identical and 100 % similar to a <em>N. centrifera</em> sequence from a Florida cottontail rabbit. The other six <em>N. centrifera</em> sequences from the marsh rabbit and five cottontail rabbits matched those from a Florida marsh rabbit and a Kansas fox squirrel (<em>Sciurus niger</em>). The <em>N. cati</em> ITS-2 sequence was 100 % similar to <em>N. cati</em>. The <em>N. centrifera</em> COI sequences were more variable and fell into two groups that were 79.5 % and 79.8 % similar to <em>S. scabiei</em>. The raccoon <em>N. cati</em> COI sequence was 85.1 % (582/684) and 84.1 % (575/684) similar to Group 1 and Group 2 of <em>N. centrifera</em>, respectively, and 80.3 % similar to <em>S. scabiei</em>. Overall, these data may indicate that notoedric mange is endemic in rabbits and squirrels in Florida, confirm raccoons as hosts for <em>N. cati</em>, and highlight the utility of molecular characterization in mite speciation. Additionally, new sequences of <em>Notoedres</em> were generated that will facilitate future phylogenetic analyses.

Despite these concerns, data on tick infestations in confiscated African pangolins and scales remain scarce. This study aims to identify tick species associated with confiscated pangolins and scales using morphological and molecular approaches. A total of 275 ticks were collected from 17 rehabilitated African pangolins (<em>Smutsia temminckii, Phataginus tricuspis, Phataginus tetradactylus</em>) and nine bags of seized scales. Representative specimens (n = 53) were genetically analyzed by amplifying the 16S rRNA fragment and comparing sequences with publicly available data. Morphological identification revealed five tick species: <em>Amblyomma compressum, A. hebraeum, Ornithodoros compactus, Rhipicephalus theileri,</em> and <em>R. simus.</em> Taxonomic assignments conformed with the DNA-based identification for all species except for ‘<em>O. compactus’</em> which resulted in <em>O. moubata</em>. These discrepancies may be due to overlapping morphological characters between the two <em>Ornithodoros</em> species. Notably, ticks from the three identified genera are known vectors of pathogens causing diseases such as heartwater, <em>anaplasmosis</em>, babesiosis, theileriosis, African swine fever, and human relapsing fever.

This study examines a sample set of taeniid cestodes from African wildlife using both genetic and morphological approaches and integrates the findings into an updated checklist and definitive host index for Taeniidae documented in Africa. Furthermore, this publication provides a categorisation tool that facilitates the morphological identification of ribbon-like Taeniidae.

A total of 16 <em>Taenia</em> species and four <em>Hydatigera</em> species were identified in this sample set. Among these, twelve (eleven <em>Taenia</em> spp. and one <em>Hydatigera</em> sp.) represent genetically novel lineages. One species, recovered from three servals and one rodent, was morphologically identified as <em>Hydatigera</em> cf. <em>selousi</em>, with this study presenting the first genetic data for this species. Several genetically novel <em>Taenia</em> lineages were identified in carnivores, including cheetah, African wolf, caracal, spotted hyaena, black-backed jackal, African wild dog, lion, and leopard. These are provisionally designated as <em>Taenia</em> spp. A-K, pending the availability of further material to support detailed morphological assessment and formal species description or assignment.
