Brucella ceti, morbillivirus, and herpesvirus have been detected from stranded cetaceans and been recognized as pathogens that may result in considerable cetacean morbidity and mortality. Beaked whale circovirus has been reported in multiple cetacean species in Hawaii, USA, and the western Pacific Ocean, but the pathologic relevance in these species remains uncertain. We screened for the presence of Brucella in 66 cetaceans of 17 species that stranded in Hawaii 2000-24 by targeting the insertion sequence 711 partial sequence using PCR. All Brucella-positive individuals were PCR tested for herpesvirus, morbillivirus, and circovirus coinfections. Of 66 individuals across eight species, 21 (31.8%) were positive for Brucella; 10/10 (100%) striped dolphins (Stenella coeruleoalba) and 5/6 (83.3%) pygmy killer whales (Feresa attenuata) tested were positive. Tissue positivity was highest in brain and lung tissue, with corresponding meningitis, hydrocephalus, and bronchopneumonia. We detected Brucella positivity across seven species; 7/10 (70%) of the positive subadults were striped dolphins. A single humpback whale (Megaptera novaeangliae) fetus was positive; the mother had died during dystocia. Viral coinfections were detected in 6/21 (33.3%) positive cases; circovirus was the most common coinfection, followed by morbillivirus and herpesvirus. Brucella ceti infection caused fatal disease in cetaceans in Hawaii, with a high percentage of strandings due to neurobrucellosis in striped dolphins.","PeriodicalId":17602,"journal":{"name":"Journal of Wildlife Diseases","volume":" ","pages":"522-529"},"PeriodicalIF":1.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143764029","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}

Leptospira interrogans serovar Pomona is endemic in free-ranging California sea lions (CSLs; Zalophus californianus), and leptospirosis is frequently diagnosed in stranded CSLs. Serum microscopic agglutination test (MAT) is a commonly performed diagnostic assay, and CSLs with clinical disease have reliably elevated MAT titers. However, MAT results may not be available for several days after sampling. Given the zoonotic and high transmission potential of Leptospira spp., a point-of-care diagnostic test would be valuable in rehabilitation and managed care settings and during outbreak response efforts. The IDEXX SNAP and Zoetis WITNESS anti-Leptospira antibody tests are rapid diagnostic tools that have been validated in dogs and give a qualitative (positive or negative), not quantitative (exact titer), result. The SNAP test uses ELISA to detect both immunoglobulin (Ig)M and IgG antibodies, whereas the WITNESS test is a lateral flow assay that only detects IgM. We compared SNAP and WITNESS results with MAT results by using serum collected from stranded and free-ranging CSL with negative, low, medium, and high anti-Leptospira antibody titers as previously determined by MAT. Percent agreement between SNAP and MAT results was high, with a Cohen's kappa statistic of 0.957. No WITNESS tests were positive. These findings suggest that the SNAP test may be useful for detecting anti-Leptospira antibodies and ruling out leptospirosis in CSL.","PeriodicalId":17602,"journal":{"name":"Journal of Wildlife Diseases","volume":" ","pages":"461-466"},"PeriodicalIF":1.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143370802","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}

In ungulates, trace minerals, including copper (Cu), selenium (Se), and zinc (Zn), are essential for immune function, as well as hoof development and maintenance. Trace minerals may influence the occurrence or severity of treponeme-associated hoof disease (TAHD), a debilitating infectious disease of free-ranging Roosevelt and Rocky Mountain ecotypes of elk (Cervus canadensis). To investigate associations between mineral levels and TAHD, we collected postmortem liver and hoof samples from free-ranging Roosevelt elk during TAHD surveillance from 2020 to 2021 in Del Norte and Humboldt counties, California, USA. We analyzed mineral levels in liver samples (n=81; 41 TAHD positive, 40 TAHD negative) to improve baseline information on the range of trace mineral concentrations for elk in the region. Hooves were examined for the presence of TAHD, and the severity of observed gross lesions was scored. Using the combined mineral and surveillance data, we constructed logistic and ordinal regression models to ask whether TAHD occurrence and TAHD lesion severity were associated with mineral concentrations, respectively. We did not find support for our hypothesis that lower mineral levels contributed to higher TAHD occurrence in the sample populations; however, Cu and Se in both TAHD-affected and unaffected elk were below previously reported reference ranges, so we cannot discount suboptimal levels of these minerals as potential risk factors for TAHD in elk in this region. Contrary to our hypothesis, higher Zn levels were correlated with TAHD occurrence and increasing lesion severity, which may be evidence of a host-mediated nutritional immune response to infectious disease. Further investigation is needed to understand regional variation in mineral levels and the impact on wildlife health before mineral supplementation can be recommended as an effective management tool.","PeriodicalId":17602,"journal":{"name":"Journal of Wildlife Diseases","volume":" ","pages":"357-369"},"PeriodicalIF":1.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143537430","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}

It has not previously been confirmed in gray wolves (Canis lupus lupus). Postmortem radiographs of three free-ranging, juvenile sibling wolves revealed osteochondrosis in at least one of the glenohumeral joints (GHJs) in all individuals. Whole-body computed tomography and computed tomographic arthrography of both GHJs were performed in one case and suggested bilateral osteochondrosis lesions of the humeral head without cartilage flap formation. Cytologic examination of synovial fluid from the GHJs of this wolf was consistent with degenerative arthropathy. Macroscopic and histopathologic examination of the GHJs confirmed the presence of osteochondrosis manifesta in both males and the female.

The heterophil to lymphocyte (H:L) ratio has been proposed as a measure of physiological stress. This study investigates the prevalence of the bacterial pathogen Mycoplasma gallisepticum and Haemosporidia in Mexican House Finches (Haemorhous mexicanus). To test the extent to which pathogens stress their hosts we compared total and differential leucocyte counts in four groups of birds with different infection statuses: birds co-infected with M. gallisepticum and haemosporidia, birds infected with either M. gallisepticum or haemosporidia, and birds infected with neither. We hypothesized that co-infected birds would exhibit higher physiological stress, reflected in leukocyte parameters, plus, based on previous experiments, that both M. gallisepticum and haemosporidia would benefit from the presence of each other. We found that 73.6% of House Finches were infected with M. gallisepticum, and 43.1% with haemosporida. Both pathogens had a higher load in co-infected birds. Higher H:L ratios were found in co-infected birds compared to birds with a single infection. The study highlights the complexity of immune responses under co-infection. Our results contribute to the understanding of host-pathogen interactions and stress physiology in wild birds, highlighting the importance of hematological parameters as indicators of stress and providing insights into the ecological impacts of pathogen infections in avian populations. This emphasizes the significance of studying leukocyte profiles in the wild.","PeriodicalId":17602,"journal":{"name":"Journal of Wildlife Diseases","volume":" ","pages":"334-347"},"PeriodicalIF":1.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143730584","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 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}
