We assessed a series of cases (n=8) of necrosuppurative peritonitis, lymphadenitis, and\/or pyelonephritis in wild juvenile raccoons (Procyon lotor) that died under rehabilitator care in New York, New Jersey, and Wisconsin, US, between July 2020 and December 2023, plus a retrospective case of a juvenile raccoon necropsied from New York in August 2011. Gross necropsy (n=9) and histopathology (n=9) were performed to characterize the lesions, whereas bacterial culture (n=8) was used to identify and characterize the bacteria and associated phenotype. We observed gram-negative short rods and coccobacilli (7\/9; 78%), fibrinosuppurative peritonitis of variable severity (7\/9; 78%) correlated to gross pyoabdomen (5\/9; 56%) or abscessation (2\/9; 22%), lymphadenomegaly and associated necrosuppurative lymphadenitis (5\/9; 56%), and urinary tract disease (3\/9; 33%). Aerobic culture of affected tissues isolated Klebsiella pneumoniae (n=4), K. pneumoniae subsp. ozaenae (n=2), Klebsiella variicola (n=1), and Klebsiella sp. (n=1). Our study strongly suggests an association of bacteria within the K. pneumoniae complex with peritonitis, lymphadenitis, and pyelonephritis in raccoons. Disease might be associated with underlying nosocomial infection given that all animals were under rehabilitator care at the time of death.<\/jats:p>","DOI":"10.7589\/jwd-d-24-00027","type":"journal-article","created":{"date-parts":[[2025,1,31]],"date-time":"2025-01-31T07:40:08Z","timestamp":1738309208000},"page":"173-179","source":"Crossref","is-referenced-by-count":0,"title":["Klebsiella Pneumoniae Complex-Associated Peritonitis, Lymphadenitis, and Pyelonephritis in Juvenile Raccoons (Procyon lotor) Under Rehabilitator Care in New York, New Jersey, and Wisconsin, USA"],"prefix":"10.7589","volume":"61","author":[{"given":"Zoe E.","family":"Mack","sequence":"first","affiliation":[{"name":"Department of Population Medicine and Diagnostic Sciences, Cornell University College of Veterinary Medicine, 240 Farrier Rd., Ithaca, New York 14850, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorelei L.","family":"Clarke","sequence":"additional","affiliation":[{"name":"Department of Pathobiological Sciences, University of Wisconsin\u2013Madison School of Veterinary Medicine, 2015 Linden Dr., Madison, Wisconsin 53706, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth L.","family":"Buckles","sequence":"additional","affiliation":[{"name":"Department of Population Medicine and Diagnostic Sciences, Cornell University College of Veterinary Medicine, 240 Farrier Rd., Ithaca, New York 14850, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca J.","family":"Franklin-Guild","sequence":"additional","affiliation":[{"name":"Department of Population Medicine and Diagnostic Sciences, Cornell University College of Veterinary Medicine, 240 Farrier Rd., Ithaca, New York 14850, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena Alina","family":"Demeter","sequence":"additional","affiliation":[{"name":"Department of Population Medicine and Diagnostic Sciences, Cornell University College of Veterinary Medicine, 240 Farrier Rd., Ithaca, New York 14850, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4415","reference":[{"key":"12","doi-asserted-by":"crossref","unstructured":"M Hanson, N Hollingshead, K Schuler, et al.  \"PLoS One.\"  16, \"Species, causes, and outcomes of wildlife rehabilitation in New York State.\" e0257675 (2021)","DOI":"10.1371\/journal.pone.0257675"},{"key":"1","doi-asserted-by":"crossref","unstructured":"CK Bozek, S Prange, SD Gehrt,  \"Urban Ecosyst.\"  10, \"The influence of anthropogenic resources on multi-scale habitat selection by raccoons.\" 413 (2007)","DOI":"10.1007\/s11252-007-0033-8"},{"key":"11","doi-asserted-by":"crossref","unstructured":"GA Grau, GC Sanderson, JP Rogers,  \"J Wildl Manag.\"  34, \"Age determination of raccoons.\" 364 (1970)","DOI":"10.2307\/3799023"},{"key":"2","doi-asserted-by":"crossref","unstructured":"C Caneiras, L Lito, J Melo-Cristino, et al.  \"Microorganisms.\"  7, \"Community- and hospital-acquired Klebsiella pneumoniae urinary tract infections in Portugal: Virulence and antibiotic resistance.\" 138 (2019)","DOI":"10.3390\/microorganisms7050138"},{"key":"3","unstructured":"FL Carson  and C Cappellano  \"Histotechnology: A self instructional text.\"  400 (2020)"},{"key":"4","doi-asserted-by":"crossref","unstructured":"JE Choby, J Howard-Anderson, DS Weiss,  \"J Intern Med.\"  287, \"Hypervirulent Klebsiella pneumoniae \u2013 Clinical and molecular perspectives.\" 283 (2020)","DOI":"10.1111\/joim.13007"},{"key":"5","doi-asserted-by":"crossref","unstructured":"ME Church, KA Terio, MK Keel,  \"Pathology of wildlife and zoo animals.\"  \"Procyonidae, Viverridae, Hyenidae, Herpestidae, Eupleridae, and Prionodontidae.\" 305 (2018)","DOI":"10.1016\/B978-0-12-805306-5.00012-2"},{"key":"6","doi-asserted-by":"crossref","unstructured":"CR Collins  and R Kays  \"Anim Conserv.\"  14, \"Causes of mortality in North American populations of large and medium-sized mammals.\" 474 (2011)","DOI":"10.1111\/j.1469-1795.2011.00458.x"},{"key":"7","doi-asserted-by":"crossref","unstructured":"JP Duff, CA Bidewell, SM Williamson, et al.  \"Vet Rec.\"  179, \"Klebsiella pneumoniae of suspected human origin from free-living common seals on the east coast of England.\" 652 (2016)","DOI":"10.1136\/vr.104018"},{"key":"8","doi-asserted-by":"crossref","unstructured":"RL Ferreira, BCM da Silva, GS Rezende, et al.  \"Front Microbiol.\"  9, \"High prevalence of multidrug-resistant Klebsiella pneumoniae harboring several virulence and \u03b2-lactamase encoding genes in a Brazilian intensive care unit.\" 3198 (2019)","DOI":"10.3389\/fmicb.2018.03198"},{"key":"9","doi-asserted-by":"crossref","unstructured":"W Gaastra, RA van Oosterom, EW Pieters, et al.  \"Vet Microbiol.\"  48, \"Isolation and characterisation of dog uropathogenic Proteus mirabilis strains.\" 57 (1996)","DOI":"10.1016\/0378-1135(95)00133-6"},{"key":"10","doi-asserted-by":"crossref","unstructured":"LT.
