Postmortem findings included emaciation, gastric dilation with fluid content, and fibrinonecrotic gastritis with intralesional amebic trophozoites and cysts in the glandular region of the fundus. Transmission electron microscopy ruled out Amoebozoa of the family Entamoebidae based on the presence of mitochondria in the amoeboid organisms. PCR for pan-free-living amebae followed by next-generation sequencing of the PCR product revealed 99% identity with Naegleria australiensis. Gastric amebiasis has been reported sporadically in macropods and in leaf-eating monkeys with a sacculated stomach.

Deletion of a 212-kb region within the Bardet-Biedl syndrome 9 (BBS9) gene has been linked to a reduction in the number of piglets born alive per litter. The BBS9 mutant gene carrier-by-carrier mating scheme could result in mummification of piglets carrying 2 copies of the BBS9 mutant allele, which ultimately affects the reproductive performance of the sow. Our aim was to develop a simple, rapid, and cost-efficient method that could be applied in a BBS9 mutant gene carrier screening program in low- and middle-income countries within basic laboratory settings. Here, we report an optimized multiplex PCR assay that we have established successfully for detection of a 212-kb deletion within the BBS9 genomic sequence. We genotyped 420 animals from Yorkshire, Duroc, and Landrace purebred populations in Vietnam. We found that while the BBS9 mutant allele was not identified in Duroc pigs, the frequency of BBS9 carriers was 10% in both Yorkshire and Landrace populations. We subsequently validated our results using Sanger sequencing. Our multiplex PCR method could be utilized as a BBS9 screening test in pig breeding programs.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"847-851"},"PeriodicalIF":1.2,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11512462/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142349262","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}

Given that vaccines are not widely available, ASFV detection, including by molecular and serologic assays, is paramount to efficacious control and mitigation of ASF. ASFV-specific antibodies can be detected as early as 7-10 d postinfection in infected animals and may persist for several months or longer. Accurate detection of ASFV-specific antibody is critical for the identification of chronically infected, subclinically infected, or recovered animals. ELISAs are commonly used for the rapid screening of large numbers of animals for ASFV antibodies. The World Organisation for Animal Health recommends that ELISA-positive results should be confirmed with a second serologic method, such as an indirect immunofluorescent assay, indirect immunoperoxidase test (IPT), or immunoblot test. Commercial kits are not available for those tests. We developed and validated an in-house IPT by using a currently circulating genotype II ASFV strain as antigen. The sensitivity and specificity of the in-house IPT are comparable to the reference IPT developed by an international ASFV reference laboratory and superior to a commercial blocking ELISA.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"870-873"},"PeriodicalIF":1.2,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11529064/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142145909","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}

Both rabbits died after exhibiting clinical signs of gastrointestinal stasis. The gross findings observed in both rabbits comprised miliary, random, white-to-tan, necrotic foci throughout the spleen, liver, and lungs. Histologically, tachyzoites were observed within necrotizing inflammatory foci in the spleens of both rabbits, and in various other organs (tracheobronchial lymph node, lung, heart, and cecal appendix) of one rabbit. In both cases, the tachyzoites were immunoreactive with anti-Toxoplasma gondii antibodies. In addition, T. gondii DNA was detected via PCR and sequencing from a fresh lung sample from one rabbit and formalin-fixed, paraffin-embedded spleen, liver, femoral bone marrow, and haired skin from the second rabbit.

Over the years 2013-2022, the Southeastern Cooperative Wildlife Disease Study received 119 Sylvilagus spp. case submissions from the central and eastern United States, comprising 147 rabbits. Most (86%) of these submissions occurred after detecting RHDV2 in the United States in 2020. Laboratory data from these rabbits were retrospectively evaluated for major causes, contributors to mortality, and pathogen detections. Gross and histologic examination was performed for 112 rabbits. Common primary causes of death included trauma (n = 49), bacterial disease (n = 31), emaciation (n = 6), and parasitism (n = 6). Among the 32 rabbits with bacterial disease, 12 were diagnosed with tularemia and 7 with pasteurellosis. Rabbits with pasteurellosis had disseminated abscessation, septicemia, and/or polyserositis. Less commonly, cutaneous fibroma (n = 2), notoedric mange (n = 2), encephalitozoonosis (n = 2), neoplasia (round-cell sarcoma; n = 1), and congenital abnormalities (n = 1) were diagnosed. RHDV2 was not detected in 123 rabbits tested. Although RHDV2 has not been detected in wild lagomorphs in the eastern United States, detections in domestic rabbits from the region emphasize the need for continued surveillance. Furthermore, continued surveillance for Francisella tularensis informs public health risk. Overall, increased knowledge of Sylvilagus spp. health furthers our understanding of diseases affecting these important prey and game species.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"655-665"},"PeriodicalIF":1.2,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11457750/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141296344","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}
