Lesions of anasarca described in the 7 ST cases (66 chickens) identified from the CAHFS database included: ascites (62 of 66; 6 of 7 cases); hydropericardium and cardiomegaly (54; 6 of 7); edematous, congested lungs (24; 6 of 7); enlarged, pale kidneys (24; 6 of 7); subcutaneous edema (17; 4 of 7); cystic testes (14; 6 of 7); and cerebral edema (7; 4 of 7). Brain sodium concentrations exceeded 1,800 ppm in only 4 of 24 brains analyzed in our case series. In the feed samples analyzed from 5 ST cases, sodium concentrations exceeded the recommended 2,000 ppm; concentrations detected were 2,500-12,000 ppm.

Non-neoplastic lesions accounted for 450 diagnoses (57%) in dogs and 239 diagnoses (59%) in cats. Canine non-neoplastic lesions consisted of inflammatory lesions (286 cases; 64% of non-neoplastic lesions) and tumor-like proliferative lesions (164 cases; 36% of non-neoplastic lesions). Feline non-neoplastic lesions consisted of inflammatory lesions (228 cases; 95% of non-neoplastic lesions) and tumor-like proliferative lesions (11 cases; 5% of non-neoplastic lesions). The most common canine neoplasms were melanocytic neoplasms (103 cases; 30% of neoplasms) and epithelial neoplasms (102 cases; 30% of neoplasms), followed by mesenchymal neoplasms (90 cases; 26% of neoplasms) and round cell neoplasms (48 cases; 14% of neoplasms). Approximately 43% of melanocytic neoplasms affected Chow Chows and Labrador Retrievers, and 20% of epithelial neoplasms affected Labrador Retrievers. In cats, most tumors were epithelial (158 cases; 94% of neoplasms), followed by mesenchymal (8 cases; 5% of neoplasms) and round cell neoplasms (1 case; 1% of neoplasms). Over 50% of neoplasms of cats affected domestic shorthair cats.

Cattle are typically predisposed to BH by liver injury caused by Fasciola hepatica, although cases have been reported in cattle without evidence of this parasite. Here we describe a cluster of 14 BH cases from 7 counties in north-central to central Missouri submitted to a veterinary diagnostic laboratory between December 2020 and April 2023. Postmortem examination in all cases revealed hemoglobinuria and acute hepatic necrosis with large numbers of gram-positive bacilli with terminal-to-subterminal spores. Flukes, fluke ova, and/or fluke pigment consistent with Fascioloides magna were identified in 12 of 14 cases. Sequences of the nuclear ribosomal internal transcribed spacer 1 (ITS1) from one fluke had 100% identity to F. magna. C. novyi was detected by fluorescent antibody testing of liver impression smears (11 of 12 cases) and by immunohistochemistry of liver sections (7 of 7 cases). PCR on formalin-fixed, paraffin-embedded tissues amplified the C. haemolyticum beta toxin gene in each of the 7 cases tested.

We validated a robust and representative framework for assessing the dilution effect of sample pooling using duplex rtPCR surveillance of Theileria orientalis and Anaplasma marginale, both of which are causative agents of severe anemia in cattle and a serious threat to the cattle industry in Virginia and many other states. We used 200 known-positive samples with Ct values representative of typical surveillance results in a series of pools in which we re-tested each sample individually, followed by each sample diluted in equal volumes with negative samples to make pools of 2, 4, 6, 8, and 10 total samples. We compared the Ct values of the individual positives with the Ct values of each pool size to determine if Ct values increase past the limit of detection in the 45-cycle assay. We observed a maximum of 2% sensitivity loss (no more than 2 of 100 samples returned a false-negative result) for both T. orientalis and A. marginale during the pooling series, with lower-than-expected average Ct increase and sensitivity loss. We conclude that pooling up to 10 samples would be acceptable for regional surveillance of T. orientalis and A. marginale using our rtPCR assay. The described strategy is applicable to validate pooling for a wide range of single and duplex rtPCR assays, which could expand efficient disease surveillance.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"71-78"},"PeriodicalIF":1.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11559834/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142502996","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}

Harsh bronchovesicular sounds were auscultated throughout both lung fields, and the mare had signs of moderately painful laminitis. Thoracic ultrasonography revealed lung consolidation throughout the dorsal aspect of both lungs, and radiography revealed an extensive diffuse-to-patchy bronchointerstitial lung pattern. The mare's clinical condition rapidly deteriorated, and euthanasia was elected. On postmortem examination, the lungs, omentum, spleen, liver, adrenal glands, kidneys, and femur contained 0.5-2.5-cm, firm, tan nodules. Histologically, the lungs, spleen, liver, kidneys, adrenal glands, omentum, left eye, and femur were infiltrated by bundles and nests of pleomorphic polygonal-to-spindloid cells intermixed with frequent multinucleate cells. Lymphatic vessels in the affected tissues were frequently distended with tumor emboli. Neoplastic cells were diffusely positive for vimentin, desmin, sarcomeric actin, myoblastic differentiation protein 1, and myogenin, supportive of the diagnosis of rhabdomyosarcoma (RMS), which is a rare neoplasm in horses. Cross-striations were not evident with H&E or phosphotungstic acid-hematoxylin stains. Markedly pleomorphic neoplastic cells, multinucleate cells, and lack of cross-striations suggested the subclassification of pleomorphic RMS.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"203-207"},"PeriodicalIF":1.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11559810/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142290172","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 a case of NK-cell lymphoproliferative disorder/leukemia in a 20-y-old captive female rhesus macaque (Macaca mulatta). The animal clinically had mild splenomegaly and marked lymphocytosis with small-to-medium lymphocytes in blood smears. By flow cytometry and cluster differentiation, the lymphocytes were CD3-negative, CD8-positive, CD4-negative, and CD20-negative for cell surface markers; immunohistochemistry revealed the presence of intracellular CD3 and granzyme B. This immunoprofile is consistent with a NK-cell phenotype. Histologically, these cells were predominantly intravascular within the splenic red pulp, liver sinusoids, and to a lesser degree bone marrow. Oncogenic viruses, such as Mason-Pfizer monkey viruses (MPMV; formerly, and commonly known as, simian retroviruses or SRV; Retroviridae, Betaretrovirus maspfimon); simian immunodeficiency virus (SIV; Retroviridae, Lentivirus simimdef), and primate T-lymphotropic virus 1 (PTLV1; commonly known as simian T-lymphotropic virus type 1, STLV1; Retroviridae, Deltaretrovirus priTlym1), were not detected in this animal by serology. Immunohistochemistry using EBNA2 antibody to detect rhesus and cynomolgus monkey lymphocryptovirus (McGHV4/RLV and McGHV10 respectively; Orthoherpesviridae, Lymphocryptovirus macacinegamma4 and Lymphocryptovirus macacinegamma13, respectively) was negative.
