초록
From July to December 2022, we investigated the incidence of enteric pathogens causing diarrhea in calves under 100 days old at 22 farms across Korea. A total of 354 calves (including 247 dairy calves and 107 Korean native calves) were included. We used commercially available rapid diagnostic kits to identify five enteric pathogens, including bovine rotavirus (BRV), bovine coronavirus (BCoV), Cryptosporidium. Escherichia coli (E. coli ), and Giardia . This study investigated how factors such as age, season, and birth month, which can influence the incidence of intestinal pathogens, affect the incidence of these pathogens in diarrheic dairy calves and Korean native calves. Our study found that the incidence of diarrhea-causing pathogens differed between dairy and Korean native calves. In diarrheic dairy calves, bovine rotavirus (BRV) incidence rates, correlated with season and birth month. Similarly, Cryptosporidium incidence C were associated with age and season, while Giardia incidence rates varied by season and birth month. Korean native calves, on the other hand, exhibited seasonal and birth month-related variations in BRV incidence rates, with Cryptosporidium incidence rates influenced by birth month.
