Such heterogeneity in parasitic status among individuals depends in particular on differences in their susceptibility to infection and in the habitats and resources used by the individuals. While several studies have aimed to identify individual factors and, mostly at large spatial scales, environmental factors that influence endoparasitism in wild populations, we aim in this study to investigate the influence of habitat quality (vegetation type, resource availability) on parasite burden within a population of roe deer living in a heterogeneous forest. We collected 1,469 fecal samples to measure the parasite burden on 952 roe deer captured between 1996 and 2020 in Chizé (France), a study site stratified into two contrasting sectors in terms of vegetation structure and resource quality. We quantified the effect of the sector on parasitism after considering the possible influences of age, sex, body mass and Julian date. The prevalence of parasitism was higher in individuals living in the poorer sector, but the intensity of the parasite burden was not influenced by the sector. These results suggest that within a host population, parasite infection risk would not be the same everywhere, probably due to differences in resource availability, vegetation species and density of host, showing the need to study parasitism at fine scales.","PeriodicalId":19796,"journal":{"name":"Parasite","volume":"32 ","pages":"45"},"PeriodicalIF":2.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12291545/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144708334","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}

Xenos spp. (Xenidae, Strepsiptera) are primarily parasitic to social wasps, with V. analis being the only known host in Korea. Until recently, no parasites or parasitoids on V. velutina had been discovered. In 2020, strepsipteran parasites were discovered on 11 hornet workers in Andong City, South Korea. These parasites, comprising four larvae and seven pupae, were all male, except for one individual of an undetermined sex. Molecular analysis and morphological examination identified the parasites as Xenos moutoni (du Buysson, 1903) and X. oxyodontes Nakase & Kato, 2013. This marks the first recorded instance of strepsipteran parasites on V. velutina in regions invaded by this hornet. Although the exact infection rate of these parasites could not be determined, it appears that native strepsipteran parasites have adapted to a non-native Vespa species. Stylopization, the condition caused by these parasites, is known to negatively affect hornet colonies: infected workers do not contribute to nest activities, hindering nest development, and infected reproductive individuals (males and new queens) do not mate, which impedes the establishment of new colonies. However, due to the hornet's high reproductive rate and compensatory mechanisms, the overall control effect of the parasites is likely to be minor.","PeriodicalId":19796,"journal":{"name":"Parasite","volume":"32 ","pages":"10"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11832165/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143441255","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}

Trichomonads, protozoan symbionts capable of infecting vertebrates, are transmitted via the fecal-oral route; they are a subgroup of Parabasalia and include some pathogenic species that pose zoonotic risks. Until now, data on the diversity and prevalence of trichomonads in Chinese Milu deer have not been reported. To better understand the colonization status of trichomonads, fecal samples from 112 Milu deer across five nature reserves in China were collected. The ITS-1/5.8S/ITS-2 sequences were amplified using PCR to investigate the colonization rate of trichomonads and to assess evolutionary relationships and genetic characteristics through phylogenetic analysis. An occurrence of 38.39% was recorded in Milu deer, with sample collection sites (OR = 55.159, 95% CI = 3.166-961.113, p = 0.006), high relative humidity and average annual rainfall (OR = 11.675, 95% CI = 1.747-77.781, p = 0.011) identified as significant risk factors for trichomonads colonization. Undescribed trichomonads from four genera were identified, including Simplicimonas spp., Hypotrichomonas spp., Hexamastix spp., and Tetratrichomonas spp. To our knowledge, this is the first study to report on trichomonads in Milu deer in China.

Two experimental studies were conducted to evaluate the efficacy of afoxolaner formulated in an oral tablet (NexGard®) against induced infestations of A. maculatum in dogs. These Good Clinical Practice (GCP) studies used a randomized, negative controlled and masked design. In each study, 10 dogs were allocated to an untreated group and 10 dogs to a treated group, dosed once on Day 0 with a combination of tablets targeting the minimum therapeutic dose (2.5 mg/kg afoxolaner).

In this study, a real-time SYBR Green PCR assay was developed to detect Babesia and Theileria species in hard ticks (N = 65) and cattle blood samples (N = 143) from Thailand. Using primers targeting the mitochondrial cytochrome b gene for Babesia and the nuclear 18S rRNA gene for Theileria, the assay measured specific melting temperatures (Tm) for each species. The results showed distinct Tm values for Babesia bigemina (74.38 ± 0.04 °C), Babesia bovis (75.7 ± 0.06 °C), Theileria orientalis (74.61 ± 0.03 °C), Theileria sinensis (75.84 ± 0.03 °C), and Theileria annulata (74.06 ± 0.03 °C). The assay demonstrated high specificity, with a cutoff cycle threshold of < 35 cycles and a minimum detectable concentration of 10 copies/μL. Significant species differences in melting curves were confirmed using Tukey's HSD test (p < 0.05). Theileria orientalis was detected in 8.4% of cattle blood samples, while T. sinensis was found in 25.9%, and B. bigemina in 0.7%. Theileria orientalis was also detected in 7.7% of tick samples, T. sinensis in 16.9%, and B. bigemina in 6.1%.

Although Rhipicephalus bursa is a known biological vector of B. ovis, the dynamics of vertical (transovarial) transmission are poorly understood. In the present study, the transovarial transmission of B. ovis was investigated experimentally in four continuous generations of R. bursa under laboratory controlled conditions. A total of 11 sheep were used during the study. An initial stabilate co-infected with B. ovis and Theileria ovis was inoculated into a splenectomized sheep, followed by an infestation with Babesia-free adult R. bursa. Study of dead tick bodies and larval pools by molecular methodology confirmed the elimination of T. ovis and the vertical transmission B. ovis. Rhipicephalus bursa ticks derived vertically from F1 to F4 generations kept high levels of infection (98% in F3 adults), and consistently led to severe clinical babesiosis in both immunosuppressed and immunocompetent sheep. Although all feeding stages became infected while feeding on their hosts, only adult ticks were able to transmit the parasite to vertebrate hosts. Our findings demonstrate that B. ovis can be transmitted vertically through several tick generations, while preserving its ability to cause severe disease, even without selective pressure. The virulent, mono-infected B. ovis strain developed in this study will provide an infectious challenge model for future vaccine and pathogenesis studies under field-relevant conditions.","PeriodicalId":19796,"journal":{"name":"Parasite","volume":"32 ","pages":"60"},"PeriodicalIF":2.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12445847/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145086645","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}

The prevalence and diversity of microsporidian parasites exhibited strong seasonal variations. Although parasites associated with the pet trade were not detected, we highlight the acquisition of native parasites by feral N. davidi, which seems to be a suitable alternative host for native host-generalist microsporidians. Our findings indicate that all prerogatives for spillback events to occur are met. Feral N. davidi may establish and survive year-round in European rivers with natural thermal regimes.
