These breeds are employed as part of trophic rewilding initiatives aimed at maintaining biodiverse ecosystems through natural grazing patterns. Our primary goal was to derive RIs for liver mineral concentrations for these cattle populations. We collected and analyzed liver samples from 96 cattle from 14 sites in the Netherlands and used inductively coupled plasma mass spectrometry to measure concentrations of trace elements and heavy metals, including arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, selenium, vanadium, and zinc. The statistical analysis included Pearson product moment correlations and k-means clustering to evaluate patterns within the data. The highest significant correlations were between liver cadmium concentrations and animal age, and between liver copper and selenium concentrations. Breed-related differences were found for liver cadmium and molybdenum concentrations, but we could not isolate breed-differences in forage selection from environmental variables such as soil composition. Liver copper levels in many animals were below thresholds typically used to indicate copper deficiency in farmed cattle.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"552-558"},"PeriodicalIF":1.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11948226/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143700813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we describe 2 unrelated outbreaks of acute fatal leptospirosis caused by L. kirschneri in suckling lambs and calves diagnosed following a flooding event in the spring of 2023 in northern Uruguay. In outbreak 1, the sheep flock was raised in a low-lying area previously used for rice cultivation; 20 lambs died after developing apathy, jaundice, and hemoglobinuria. In outbreak 2, 2 calves were found dead. At autopsy, 4 lambs and 2 calves had marked jaundice, hemoglobinuria, dark-red kidneys, and hepatomegaly. Microscopically, we found marked hemoglobinuric nephrosis, lymphohistiocytic tubulointerstitial nephritis, hepatocellular dissociation, and random hepatocellular necrosis with periportal lymphohistiocytic hepatitis and canalicular cholestasis. Positive immunostaining for Leptospira sp. was found in the liver (lamb C), both the liver and kidney (calf B), and the liver (calf A). Leptospira kirschneri was PCR-confirmed using kidney and liver samples from the autopsied animals. Acute leptospirosis caused by L. kirschneri has not been reported previously in sheep and cattle, to our knowledge. Our findings highlight that L. kirschneri infection can cause acute leptospirosis in unvaccinated lambs and calves.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"679-683"},"PeriodicalIF":1.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12075170/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144007532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted proteome analysis using liquid chromatography-tandem mass spectrometry to identify the amyloid precursor protein in a 13-y-old male mixed-breed dog with amyloid deposition in intramural coronary arteries, and identified fibrinogen Aα-chain. This form of amyloidosis is characterized by the deposition of amyloid derived from fibrinogen Aα-chains, which has been reported previously only in humans and Japanese squirrels. Within amyloid deposits in the intramural coronary arteries of our canine case, the αC connector region was identified in abundance, whereas in humans and Japanese squirrels, the amyloid arises from the αC domain.

We examined 252 mammary masses from 183 dogs to determine the prevalence of amyloid deposition and elucidate etiologic factors. Histologically, amyloid deposition was observed in 88 of 252 (35%) mammary masses. Amyloid deposition patterns were categorized into 3 types: stromal deposition (ST), deposition in corpora amylacea (CA), and precipitation within luminal secretions (PR). Of the 88 amyloid deposition cases, 49 were intra-tumoral, especially for ST-type amyloid deposits, which were all intra-tumoral. Immunohistochemistry and mass spectrometry revealed that ST-type amyloid deposits were positive for either serum amyloid A or α-S1-casein, depending on the sample; all CA- and PR-type amyloid deposits were positive for α-S1-casein. Statistically, intra-tumoral ST-type amyloid deposition was significantly more frequent in histologic grade II (p = 0.009) or III (p < 0.001) mammary tumors. In contrast, amyloid deposition in extra-tumoral tissues is significantly associated with aging (p = 0.002). Our findings suggest that the disruption of proteostasis in the canine mammary gland associated with tumorigenesis and aging can readily induce amyloid formation.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"574-583"},"PeriodicalIF":1.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11966624/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143763646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
