The animal in this case report was a 10-year-old male Taiwanese monkey (Macaca cyclopis) kept at a zoo of South Korea. Over the last three years, a cauliflower-shaped masses have been noted on the gingiva near the incisor and molar teeth on right maxilla. Consequently, this monkey have undergone surgical removal of the mass annually. Grossly masses showed pinkish color. Histopathological findings, typical spindle cell tumor composed of collagen fibers. Infiltration by plasma cells and lymphocytes is found unrelated to ulceration of the surface epithelium. This is the first report of peripheral odontogenic fibroma in a Formosan rock macaque.

From November 2021 to October 2022, 151 pigs were discarded due to the suspected salmonellosis, when assessed by antemortem inspection at slaughterhouses in Gwangju. Among them, 85 cases shown with the rectal stricture were confirmed to be infected with Salmonella spp, when assessed by postmortem inspection and Salmonella -oriented culture in the laboratory, accounting for 56.3% of the carcass discard cases. Salmonella spp. were isolated in 58 cases (68.2%) out of 85 total discard cases. As for serotyping of the Salmonella isolates, 28 cases (48.3%) belonged to serogroup B and 28 cases (48.3%) belonged to serogroup C, those were the most frequent isolates, and 2 cases (3.4%) belonged to serogroup E. The most prevalent serotype was Rissen (39.7%), followed by I4,[5],12:i:- (37.9%), Derby (8.6%), Bareilly (5.2%), Infantis (3.4%), Give (3.4%), and Typhimurium (1.7%). The 58 isolates of salmonellae showed resistance to tetracycline (63.8%), chloramphenicol (56.9%), ampicillin (53.4%), and ampicillin-sulbactam (51.7%). S . Rissen showed resistance to chloramphenicol (82.6%), ampicillin (52.2%), ampicillin-sulbactam (52.2%), and tetracyclin (47.8%). S . I4,[5],12:i:- was resistant to tetracycline (90.9%), ampicillin (81.8%), ampicillin-sulbactam (77.3%), and chloramphenicol (59.1%). Among the isoates, S . Bareilly (3 strains), S . Infantis (2 strains), S . Give (2 strains), S . Rissen (3 strains), and S . I4,[5],12:i:- (1 strain) showed no resistance to the tested antimicrobials. As for the prevalence of the antibiotic resistance pattern, AM-SAM-TE-C was the most common, which was shown in 15.5% of S . Rissen. At second, the resistance pattern was occurred as AMSAM— TE (12.1%) and AM-SAM-CF-CZ-FOX-CTX-NA-TE-C (12.1%), respectively in the case of S . I4,[5],12:i:-.
