, a major zoonotic pathogen distributed worldwide, causes severe infections in humans, animals, and birds. However, limited information is available regarding infection in livestock in the Republic of Korea (ROK). Herein, we determined the prevalence of infection in livestock in the ROK and identified animal species that can potentially transmit to humans.

- The study focused on enteric protozoan parasites affecting pre-weaned calves in South Korea, which can lead to serious health issues and economic losses in the cattle industry due to diarrhea and weight loss.
- Out of 510 fecal samples analyzed, 13.9% tested positive for certain protozoa, with significant findings regarding their prevalence related to the calves' age and the season they were tested.
- Three subtypes of the identified protozoa were discovered, with implications that the occurrence of these infections in calves is influenced by both age and seasonal factors, highlighting the need for better diagnosis and treatment strategies in calf diarrhea.
Giardia duodenalis is a protozoan parasite that infects humans, companion animals, livestock, and wildlife. Infections in cattle caused by this parasite are often asymptomatic, but such infections can cause diarrhea, reduced weight gain, and ill-thrift in young calves. Although G.

- Cryptosporidium spp. are protozoan parasites causing diarrhea in calves, and this study focused on their prevalence and types in pre-weaned calves in South Korea, where data is limited.
- A total of 460 fecal samples were analyzed, revealing three species of Cryptosporidium, with the highest infection rate found in calves aged 11-20 days, and a notable absence of co-infections.
- Eleven different subtypes of C. parvum were identified, with two subtypes being newly recognized in Korean calves, indicating significant variation in infections based on age.
is the most common species of microsporidia that infects humans and animals worldwide. However, no information is available on infection among zoo animals in the Republic of Korea (ROK). Here, we investigated the prevalence of among animals kept in zoos and the zoonotic potential of the identified.

Article Synopsis
- Korean water deer in the Republic of Korea are significant hosts for ticks and tick-borne diseases, and a study investigated the prevalence of tick-borne pathogens in rescued deer.
- The research found various tick-borne pathogens, with a notable presence of a specific pathogen related to human granulocytic anaplasmosis, which marked the first report of this infection in Korean water deer.
- Genetic analysis revealed distinct variants of pathogens within the population, showing a high genetic similarity to those found in other hosts, suggesting the potential for zoonotic transmission.
