We surveyed live-trapped American Kestrels (Falco sparverius caribaearum) for lice and other ectoparasites on the humid subtropical island of Puerto Rico during March-May 2024. The main goal was to compare the prevalence and abundance of lice on kestrels in Puerto Rico to recently published data on the lice of kestrels 1000 km away in the Bahamas, and to the lice of kestrels in an arid region of the western US (Utah). A brief general inspection of the plumage of 39 captured birds was followed by careful examination of the underside of wing primary feathers under a dissecting microscope. Two species of lice were collected, Colpocephalum subzerafae and Degeeriella carruthi, neither previously recorded from kestrels in Puerto Rico. The same two species are present on kestrels in the Bahamas. The prevalence and abundance of lice on kestrels in Puerto Rico and the Bahamas were similar, while being much greater than the prevalence and abundance of lice on kestrels in arid Utah, US. We also collected two species of hippoboscid flies (Diptera: Hippoboscidae): Microlynchia pusilla, not previously recorded on the American Kestrel, and Ornithoctona erythrocephala. These flies, as well as the lice, might affect the health of kestrels both directly, e.g., causing anemia by feeding on blood, and indirectly by vectoring endoparasites.","PeriodicalId":17602,"journal":{"name":"Journal of Wildlife Diseases","volume":" ","pages":"241-246"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142503015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We tested and optimized a method for exosomal miRNA isolation from minimally invasive, small-volume serum samples obtained from white-tailed deer (Odocoileus virginianus). We confirmed the isolation of exosomes and optimized a commercially available benchtop kit to obtain sufficient and pure RNA for miRNA sequencing. The selected method for RNA extraction combines two 500-μL serum aliquots into one elution column and re-eluting the final product of the column. We identified 137 miRNA present in healthy white-tailed deer that can be used as a baseline to identify putative miRNA biomarkers of disease progression and mechanisms of infection in future comparative disease studies.

The partial 18S rRNA gene sequence was 98.7-99.7% similar to a strain of Sarcocystis zuoi that is now considered a strain of the newly described Sarcocystis kani within the larger S. zuoi species complex that contains numerous new species. These Sarcocystis spp. use Asian snakes as definitive hosts and rodents, shrews, or tree shrews as intermediate hosts. Pythons are the definitive host for several Sarcocystis spp. in Asia, including a related parasite (Sarcocystis singaporensis) that has been used as a biologic control agent for Rattus spp. in southeast Asia. It is probable that increasing numbers of invasive Burmese pythons (Python bivittatus) in the Florida Keys are contributing to the spread of this parasite in addition to imposing predation pressure on both rodents and native snakes.

Paired with readily accessible samples that accurately reflect CWD status, the real-time quaking-induced conversion (RT-QuIC) assay has the potential to enable more effective CWD surveillance and interventions. We evaluated the feasibility of RT-QuIC as a CWD diagnostic test using 6-mm ear tissue biopsies from elk (Cervus canadensis). First, we evaluated the effect of ear spatial location on seeding activity. We observed an effect of ear punch spatial location on the amyloid formation rate (AFR): Samples collected from the periphery of the ear evidenced a statistically significant increase in AFR relative to ear punches from the ventral midline. Gross microdissection of an ear pinna suggested that there was more small nerve innervation around the periphery of the ear. Second, we evaluated the diagnostic sensitivity, specificity, and predictive value of RT-QuIC using ear punches from elk that had been previously diagnosed via ELISA testing. We evaluated the impact of nonstatistical and statistical approaches on diagnostic accuracy. Specificity and positive predictive value were perfect when statistical analyses were used to evaluate the binomial distribution (CWD positive versus CWD negative) of the data. Conversely, sensitivity and negative predictive value were modest, independent of the application of statistical analysis, indicating that RT-QuIC may be susceptible to false-negative data in this context. Taken together, our data support the idea that RT-QuIC, when paired with US Department of Agriculture-approved diagnostic tests, may provide more time to stakeholders for making major management decisions.","PeriodicalId":17602,"journal":{"name":"Journal of Wildlife Diseases","volume":" ","pages":"64-75"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142770272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leishmaniosis is a vector-borne disease caused by the protozoan Leishmania infantum. In general, this infection has been associated with dogs, cats, and humans. However, epidemiologic studies and reports confirm that the parasite is able to infect many other mammalian species. Recent evidence has demonstrated that ruminants in endemic areas are exposed to L. infantum infection. Moreover, climate change has allowed the northward spread of vector species, causing the expansion of L. infantum infection in regions traditionally classified as nonendemic in Europe. The aim of this study was to determine the presence or absence of anti-L. infantum antibodies in serum samples from 343 European bison in Poland, collected from 2017 to 2023. For this purpose, the presence of anti-Leishmania antibodies was analyzed using an in-house multispecies ELISA. Anti-Leishmania antibodies were detected in four animals, an overall seroprevalence of 1.17%.

Several members of the Cervidae, including Rocky Mountain elk (Cervus canadensis nelsoni), are susceptible to CWD. There is no evidence of complete genetic resistance to CWD; the M132L polymorphism in the elk prion protein gene influences the incubation period: longest in 132LL, intermediate in 132ML, and shortest in 132MM elk. We retrospectively analyzed six female 132LL elk housed in an environment heavily contaminated with prions to 1) document clinical outcomes and incubation periods, 2) describe PrPSc distribution and extent in tissues, and 3) characterize their histologic lesions. In five of six elk, PrPSc was detected postmortem, with a distribution pattern distinct from that of 132MM and 132ML elk; time to clinical CWD onset CWD ranged from 73 to 117 mo (6.1-9.8 yr). Although the remaining animal was observed for 220 mo (18.3 yr), PrPSc was not detected in its tissues postmortem. This study suggests that 132LL elk infected via natural exposure may live even longer with CWD than previously thought, but ultimately remain susceptible. We also report a distinct distribution of PrPSc in 132LL genotypes and highlight unusual histologic findings. Understanding the relationship between cervid genetics and CWD is of increasing importance, especially given the growing interest in leveraging genetics that delay disease onset despite not preventing infection.","PeriodicalId":17602,"journal":{"name":"Journal of Wildlife Diseases","volume":" ","pages":"199-205"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142290156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
