This study aimed to enhance the understanding of transmission dynamics within the great Serengeti ecosystem. (2) Methods: A total of 37 adult specimens were collected from a leopard () (n = 1) in Maswa Game Reserve and 7 from a lion () (n = 1) in Loliondo.

18S rRNA gene metabarcoding for investigation of gastrointestinal parasite diversity in great cormorants.

The great cormorant (Phalacrocorax carbo) is a migratory, fish-eating bird that may act as a carrier for various pathogens, raising potential ecological and public health concerns. This study investigated the diversity of gastrointestinal parasites in great cormorants from the Republic of Korea using 18S rRNA gene metabarcoding and conventional diagnostic methods. Fecal samples were collected from 10 great cormorants in Korea, and DNA was extracted for metabarcoding targeting the V4 and V9 regions of the 18S rRNA gene using the MiSeq platform.

Complete Mitochondrial Genome Analysis Reveals Genetic Diversity in the Narrow-Ridged Finless Porpoise () Across East Asian Waters.

The narrow-ridged finless porpoise ( Pilleri & Gihr 1972) is one of the most endangered cetacean species inhabiting East Asian waters. Complete mitogenome analysis offers accurate phylogenetic insights; however, complete mitogenome sequences for the narrow-ridged finless porpoise have so far been restricted to specific regions, mainly in China, and no sequences are available from Korean or Japanese populations. To address this gap, in this study, we developed a multiplex PCR primer panel to sequence the complete mitochondrial genome of the porpoise and sequenced 23 individuals of , a subspecies of , from Korean waters using next-generation sequencing.

First record of sp. (Acanthocephala: Polymorphidae) recovered from a northern fur seal, (Chordata: Otariidae), in Korea.

Importance: Species of the genus are acanthocephalan parasites widely distributed among fish-eating mammals and birds. However, their occurrence in pinnipeds within Korean waters has been rarely documented. Previously, only a single case involving in a spotted seal has been reported.

Comparison of prevalence and strongyle egg counts per gram of feces in horses at pasture and in stables following ivermectin/praziquantel treatment.

Equine strongyle infections are prevalent among grazing horses worldwide, yet research on anthelmintic efficacy and parasite management strategies in South Korea remains limited. This study investigated the infection dynamics and parasite burden in horses managed under different systems (pasture vs. stable) over a one-year period in Jeju, South Korea, assessing the impact of management practices on parasite burden and the effectiveness of current deworming regimens.

Thelazia callipaeda (Nematoda: Spirurida) infections in 2 wildlife species, Prionailurus bengalensis and Nyctereutes procyonoides, in Korea.

Thelazia callipaeda (Spirurida, Thelaziidae), a parasitic eye worm causing thelaziasis has been reported in humans and dogs in Korea. However, its occurrence in other potential reservoir hosts, including wild animals, remains unclear. In the present study, we described the 2 cases of thelaziasis from both of feral and captive wild animal in Korea.

Infection status of Baylisascaris transfuga in captive Asiatic black bears (Ursus thibetanus) from three bile farms in South Korea, with molecular analyses.

Bears harbor various endoparasites that pose risks to humans and other animals. However, information on parasitic infections in Asiatic black bears in South Korea (Korea) is limited, and potential hazards still exist because of the close contact between bears and humans on bile farms. The present study was conducted to assess the gastrointestinal parasite infection status in captive Asiatic black bears (Ursus thibetanus) at bile farms in Korea.

Gasterophilus intestinalis infestation in lion (Panthera leo) and plains zebra (Equus quagga) in the Serengeti ecosystem: Morphological and molecular profiling.

This study was conducted to clarify the host specificity and the geographical distribution of Gasterophilus species (Diptera, Oestridae) in the Serengeti ecosystem. A total of 317 larvae were recovered from two common zebras (Equus quagga, formerly Equus burchellii) in Maswa Game Reserve, and 58 larvae were recovered from an African lion (Panthera leo) in the Serengeti National Park. The study emphasizes the rare occurrence of Gasterophilus sp.

Metabarcoding of pathogenic parasites based on copro-DNA analysis of wild animals in South Korea.

Four species of dominant wild animals, namely, , , , and , are hosts of potential infectious agents, including helminths and protozoa. Therefore, it is necessary to analyze the infectious agents present in these wild animals to monitor and control the spread of pathogens. In the present study, fecal samples from 51 wild animals were collected from the mountains of Yangpyeong, Hoengseong, and Cheongyang in South Korea and metabarcoding of the V9 region of the 18S rRNA gene was performed to identify various parasite species that infect these wild animals.

First Report of from a Red Fox () Released for the Re-Introduction Project in South Korea.

The red fox () is a known host for various parasites, including numerous helminths and protozoans. Among these, certain species in the genus (phylum Apicomplexa) have been documented to possess the capability to infect red foxes as definitive hosts. In South Korea, red foxes have been introduced and released as part of a re-introduction program.

Adhesive Bowel Obstruction (ABO) in a Stranded Narrow-Ridged Finless Porpoise ().

In this case report, we present a rare occurrence of a narrow-ridged finless porpoise (), discovered on the coast of Jeju Island, Republic of Korea, that was afflicted with adhesive bowel obstruction (ABO), a life-threatening condition that has scarcely been reported in cetaceans. Diagnosis of ABO was confirmed via radiological and clinical assessments. Post-mortem computed tomography and necropsy revealed ABO between two loops of the jejunum at the L8 level.

Eight cases of canine thelaziosis found in two localities in Korea.

Thelazia callipaeda, a parasitic nematode that causes thelaziosis in various mammals, including humans, is known to be endemic in Korea. However, life cycle-related information on the parasite, primarily from human infection and a few dog cases, is limited. This study reports additional cases of T.

Phylogenetic and phylogeographic analyses of Anisakis simplex sensu stricto (Nematoda: Anisakidae) from the common minke whale in Korean waters.

The genus Anisakis is among the most significant parasites to public health, as it causes anisakiasis, a parasitic infection in humans resulting from consuming raw or undercooked seafood. Although the infection status of i>Anisakis in second intermediate hosts, such as marine fishes and cephalopods, and humans have been severally reported in Korea, no information about the definitive host in Korean waters is available. In 2014, 2 adult gastric nematodes were collected from a common minke whale (Balaenoptera acutorostrata) found in the East Sea, Korea.
