Objective: This study aims to isolate and identify aerobic and anaerobic bacterial species in the feces of wild KWD. Methods: Fecal samples were collected from 55 wild KWD of varying age and sex.Aerobic bacteria were cultured at 37°C for 24–48 h under standard conditions, whereas anaerobic bacteria were cultured at 37°C for 48–72 h in an anaerobic environment. Bacterial identification was conducted using DNA extraction and polymerase chain reaction amplification targeting the 16S rRNA gene. Results: The predominant aerobic bacteria identified belonged to the Firmicutes (58.18%) and Proteobacteria (41.82%) phyla, with Escherichia coli (31.82%) and Bacillus cereus (31.82%) being the most common species. Among anaerobic bacteria, most belonged to the Firmicutes (71.03%), Proteobacteria (27.10%), and Fusobacteriota (1.87%) phyla, with Paraclostridium bifermentans (28.97%) and E. coli (22.43%) being the most prevalent species.Other frequently identified anaerobic species were Fusobacterium varium, Lactococcus garvieae, Terrisporobacter glycolicus, Enterococcus faecalis, and Clostridium sporogenes. Conclusions and Relevance: Our findings indicate a diverse microbial community in the feces of water deer, offering valuable insights into their gut microbiota and its potential implications for health and ecology.

Pet rabbits are affected by the highly contagious ectoparasite Psoroptes (P.) ovis, which carries significant economic implications for the global rabbit industry. Accurate identification of the mite species remains essential to implement effective treatment and control strategies. Two approximately oneyear-old female pet rabbits were admitted to the Veterinary Teaching Hospital of Chungbuk National University due to excessive scratching of the ears and the presence of waxy debris within the ear canals. Mites were isolated from the waxy debris extracted from the ear canals and subsequently identified as Psoroptes spp. through microscopic examination. Species confirmation was achieved through mitochondrial cytochrome c oxidase subunit 1 cox1 gene analysis. The analysis revealed the mites to be P. ovis based on cox1 gene sequences. The deposited GenBank accession numbers for these sequences are OR985022 and OR985023. This represents the first report of mitochondrial cox1 gene sequences of P. ovis isolated from pet rabbits in South Korea.
