However, little is known regarding the dynamics of infection in fish. The purpose of this study was to gain a better understanding of the pathogenesis of piscine erysipelosis in the tiger barb (<jats:italic>Puntigrus tetrazona<\/jats:italic>) by investigating tissue tropisms and responses to bacterial dissemination following immersion challenge with a virulent strain recovered from diseased fish. The challenge resulted in 83% mortality by day 16. <jats:italic>Erysipelothrix piscisicarius<\/jats:italic> DNA was first detected in the skin using quantitative PCR, and bacteria were visualized in association with microscopic lesions on day 4. By day 8, <jats:italic>E.\u00a0piscisicarius<\/jats:italic> DNA was further detected in intestines, hearts, spleens, gills and skin; parenchymal organs were largely spared. The data suggest a primary cutaneous portal of entry and tropism for collagenous tissues, particularly those within vascular walls. Initial spread occurs directly from the dermis into interstitial areas of skeletal muscle, then centrally to the peritoneum and coelomic cavity following collagenous tissue pathways. Although histopathology revealed widespread bacterial dissemination over time, the severity of skin and muscle lesions with high levels of bacterial DNA identifies these tissues as primary targets of infection.<\/jats:p>","DOI":"10.1111\/jfd.13485","type":"journal-article","created":{"date-parts":[[2021,7,12]],"date-time":"2021-07-12T10:30:11Z","timestamp":1626085811000},"page":"1681-1688","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Pathogenesis of <i>Erysipelothrix piscisicarius<\/i> infection in tiger barbs (<i>Puntigrus tetrazona<\/i>)"],"prefix":"10.1111","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3176-1921","authenticated-orcid":false,"given":"Ri K.","family":"Chang","sequence":"first","affiliation":[{"name":"Department of Medicine and Epidemiology School of Veterinary Medicine University of California Davis CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6783-1509","authenticated-orcid":false,"given":"Alvin C.","family":"Camus","sequence":"additional","affiliation":[{"name":"Department of Pathology College of Veterinary Medicine University of Georgia Athens GA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7142-8555","authenticated-orcid":false,"given":"Eric","family":"Pomaranski","sequence":"additional","affiliation":[{"name":"Department of Medicine and Epidemiology School of Veterinary Medicine University of California Davis CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zeinab","family":"Yazdi","sequence":"additional","affiliation":[{"name":"Department of Medicine and Epidemiology School of Veterinary Medicine University of California Davis CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6054-9634","authenticated-orcid":false,"given":"Esteban","family":"Soto","sequence":"additional","affiliation":[{"name":"Department of Medicine and Epidemiology School of Veterinary Medicine University of California Davis CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,7,12]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1099\/00222615\u201048\u20109\u2010789"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/cmi.12002"},{"key":"e_1_2_8_4_1","first-page":"1413","article-title":"Effect of water temperature on the clinical outcome of infection with Edwardsiella ictaluri in channel catfish","volume":"191","author":"Francis\u2010Floyd R.","year":"1987","journal-title":"Journal of the American Veterinary Medical Association"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M113.454462"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1099\/ijsem.0.003838"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/jfd.12673"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/aah.10097"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1128\/cmr.2.4.354"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365\u20102672.2010.04746.x"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1128\/jb.185.9.2739\u20102748.2003"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.3354\/dao02533"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/0-387-30744-3_13"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.3354\/dao03332"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00580\u2010018\u20102856\u20105"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365\u20102230.2009.03444.x"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetmic.2009.08.012"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1751\u20100813.2001.tb10753.x"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1128\/JB.5.3.191\u2010229.1920"},{"key":"e_1_2_8_20_1","first-page":"419","volume-title":"Diseases of Swine","author":"Wood R.
