Through the utilization of tissue microarrays, 82 canine neoplasms of the disseminated neuroendocrine system from 16 different anatomic locations were evaluated. The prototypical canine neoplasm of the disseminated neuroendocrine system was composed of rounded polygonal neoplastic cells arranged in packets supported by delicate fibrovascular stroma. Neoplastic cells typically had moderate quantities of pale eosinophilic cytoplasm stippled by numerous fine argyrophilic granules, round nuclei with finely stippled chromatin, and inconspicuous nucleoli. Immunohistochemical assays utilized in this study included chromogranin A, neuron-specific enolase (NSE), microtubule-associated protein 2 (MAP2), pan-cytokeratin, oligodendrocyte transcription factor 2 (OLIG2), protein gene product 9.5 (PGP9.5), vimentin, synaptophysin, neuronal nuclei (NeuN), S100, SRY-related HMG-box 10 (SOX10), glial fibrillary acidic protein (GFAP), insulinoma-associated protein 1 (INSM1), CD56, and antigen Kiel 67 (Ki67). The 4 immunohistochemical assays that were positive in over 50% of cases included PGP9.5 (77/82, 94%), NSE (68/82, 83%), synaptophysin (59/82, 72%), and chromogranin A (56/82, 69%). In 81/82 (99%) cases, neoplastic cells immunolabeled with at least 1 of these 4 assays, and thus, these 4 immunohistochemical assays are deemed most useful when attempting to substantiate that a neoplasm is of neuroendocrine origin.","PeriodicalId":23513,"journal":{"name":"Veterinary Pathology","volume":" ","pages":"3009858251324652"},"PeriodicalIF":2.3,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143671025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-two found-dead Eurasian blackbirds were examined. USUV reverse transcriptase quantitative polymerase chain reaction (RT-qPCR) detected 12/22 infected blackbirds. Histology and immunohistochemistry for virus antigen, inflammation (anti-CD3 for T-lymphocytes), and apoptosis (anti-cleaved caspase-3 (CC3)) assessed the virus tropism and associated damage. In the eye of USUV-infected blackbirds, choroiditis was the main finding (9/12), while the pecten oculi (4/12) and optic nerves (4/12) were occasionally affected. Virus antigen was detected in the lesions. The cornea and retina lacked virus antigens and lesions. Periocular soft tissues (12/12) and eyelids (9/12) were also affected. Lesions in the choroid (P < .001), ciliary bodies (P < .01), and sclera (P < .05) were significantly associated with USUV infection. In the choroid, CD3 and CC3 strongly correlated with the virus antigen scores (P < .0001), suggesting a T-cell response and apoptosis involvement in the ocular damage. A negative correlation was identified for the virus antigen score in choroid and eyelids with USUV RT-qPCR Ct values (P < .05).

The disease is particularly prevalent in quail, and it is therefore colloquially known as quail disease. The pathogenesis of the infection is poorly understood. A retrospective study of C. colinum infection in quail submitted for necropsy and diagnostic work up to the California Animal Health and Food Safety Laboratory System between 1992 and 2022 was performed. The necropsy reports were reviewed, and polymerase chain reaction (PCR) for C. colinum (16S rRNA) was performed on formalin-fixed, paraffin-embedded tissues. C. colinum was isolated in 17% (4/24) and detected by PCR in 96% (23/24) of cases. Bobwhite quail (Colinus virginianus) were overrepresented, and the most affected quail were juveniles. Clinical history and signs were increased mortality (92%), lethargy (29%), depression (25%), diarrhea (21%), loss of nutritional condition (8%), and seizures (8%). Grossly, intestinal ulceration (100%) affecting the duodenum (79%), jejunum (100%), ileum (29%), and/or ceca (21%). Fibrinous celomitis (13%), hepatic necrosis (46%), and pectoral muscle atrophy (92%) were observed. Histologically, all quail showed multifocal ulcerative jejunitis, duodenitis, ileitis, and/or typhlitis with intralesional bacilli. Ulcerative enteritis was transmural in 92% of cases, associated with intestinal perforation in 38%, and causing celomitis in 50% of cases. Hepatic necrosis was confirmed in 63% of cases, and neuronal changes suggesting a combination of hypoxia-ischemia and hypoglycemia were found in 63% of cases. These results suggest that a diagnosis of C. colinum infection should be made based on gross and microscopic lesions, coupled with PCR.","PeriodicalId":23513,"journal":{"name":"Veterinary Pathology","volume":" ","pages":"3009858251324641"},"PeriodicalIF":2.3,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143658869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the correlation between different MAP strains and histomorphological lesions in the small and large intestines, as well as the mesenteric lymph nodes, in Swiss goats (Caprae aegagrus hircus) was investigated. Ten Swiss caprine MAP isolates were characterized using polymerase chain reaction (PCR) and enzymatic restriction-based single nucleotide polymorphism (SNP) analysis. In addition, mycobacterial interspersed repetitive units and variable-number tandem repeats (MIRU-VNTR) profiling was performed, and the correlation with histologic lesions, scored as previously described for goats, was analyzed. Furthermore, immunohistochemical expression of CD3, CD79a, Iba1, cleaved caspase 3, and interleukin (IL)-17 was evaluated, and a morphometric analysis was conducted to quantify the different inflammatory cells. Diffuse multibacillary lesions were found in C-type/L'Institut national de recherche pour l'agriculture, l'alimentation et l'environnement (INRAE) Nouzilly MIRU-VNTR (INMV)1 (2/10) and S-type/INMV220 (1/10) animals. Diffuse lymphocytic lesions occurred in C-type/INMV1 (2/10) animals, while diffuse mixed lesions were observed in S-type/INMV218 (3/10) and S-type/INMV220 (2/10) animals. No significant differences in intestinal histological lesion scores were detected between S- and C-type INMV strains. Morphometrical analysis revealed similar inflammatory and apoptotic cell numbers in the intestinal mucosa of C- and S-type animals; however, S-type animals exhibited significantly more Iba1- and cleaved caspase 3-positive cells in mesenteric lymph nodes.

In addition, polymerase chain reaction (PCR) is often performed to detect internal tandem duplication (ITD) mutations in exon 11 of the c-KIT gene (c-KIT-11-ITD) to predict the therapeutic response to tyrosine kinase inhibitors. This project aimed at training deep learning models (DLMs) to identify MCTs with c-KIT-11-ITD solely based on morphology. Hematoxylin and eosin (HE) stained slides of 368 cutaneous, subcutaneous, and mucocutaneous MCTs (195 with ITD and 173 without) were stained consecutively in 2 different laboratories and scanned with 3 different slide scanners. This resulted in 6 data sets (stain-scanner variations representing diagnostic institutions) of whole-slide images. DLMs were trained with single and mixed data sets and their performances were assessed under stain-scanner variations (domain shifts). The DLM correctly classified HE slides according to their c-KIT-11-ITD status in up to 87% of cases with a 0.90 sensitivity and a 0.83 specificity. A relevant performance drop could be observed when the stain-scanner combination of training and test data set differed. Multi-institutional data sets improved the average accuracy but did not reach the maximum accuracy of algorithms trained and tested on the same stain-scanner variant (ie, intra-institutional). In summary, DLM-based morphological examination can predict c-KIT-11-ITD with high accuracy in canine MCTs in HE slides. However, staining protocol and scanner type influence accuracy. Larger data sets of scans from different laboratories and scanners may lead to more robust DLMs to identify c-KIT mutations in HE slides.","PeriodicalId":23513,"journal":{"name":"Veterinary Pathology","volume":" ","pages":"152-160"},"PeriodicalIF":2.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11874474/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142475924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
