“…The prey spectra of large carnivorans include smaller carnivorans. In addition, cannibalism is a characteristic of such species as Ursus arctos, U. thibetanus, Vulpes vulpes, and Prionailurus bengalensis (Yudin, 1986;Seryodkin et al, 2012;Seryodkin, 2015a;Seryodkin & Burkovskiy, 2019). In the Primorsky Krai, the diet of all large carnivorans includes Sus scrofa, which is also susceptible to Trichinella infection (Britov, 1995).…”

“…Small rodents, birds, and, to a lesser extent, other animals, are of the highest importance in Prionailurus bengalensis' diet (Yudin, 2015). The diet of this species includes insectivores, Vulpes vulpes, Nyctereutes procyonoides, and individuals of the same species (Seryodkin & Burkovskiy, 2019). Together with necrophagy, this promotes Trichinella infection.…”

“…Trichinella pseudospiralis is often recorded in birds (Pozio, 2005;Garkavi, 2007). Since in the Primorsky Krai birds are one of the main food sources of P. bengalensis (Yudin, 2015;Seryodkin & Burkovskiy, 2019), infection may occur when they are eaten. In addition, small rodents and insectivores (Garkavi, 2007), also consumed by P. bengalensis, being the links for spreading of T. pseudospiralis in the study area.…”

Nematodes of the genus Trichinella cause trichinosis, which is a zoonotic disease of humans, wild and domestic animals. In the Russian Far East, trichinosis has a natural focal character. Carnivorans (Carnivora), living in natural ecosystems including Protected Areas, are the main hosts of Trichinella. The peculiarities of Trichinella circulation in natural environment and the parasite prevalence in wild animals of different species remain poorly understood as well as the species composition of the Trichinella genus in the studied region. Muscle samples were obtained from 731 specimens belonging to 14 species and four families (Mustelidae, Ursidae, Felidae, and Canidae) in Primorsky Krai (Russia) in 2010-2020 and examined on Trichinella. The parasites were found in 124 specimens belonging to 11 species. The highest Trichinella prevalence was observed in Vulpes vulpes (64%), Ursus arctos (57%), and Lynx lynx (50%). A relatively high ratio of infected animals (30-50%) was found in Nyctereutes procyonoides, Ursus thibetanus, and Prionailurus bengalensis. The parasite prevalence was relatively low in the representatives of the Mustelidae family. Three species of the genus Trichinella (T. nativa, T. spiralis, and T. pseudospiralis) were found for carnivorans inhabiting the study area. Trichinella nativa was found the most frequently in natural ecosystems. Trichinella pseudospiralis was discovered for the first time both for P. bengalensis and for the area of the Primorsky Krai. The Carnivora ecology contributes to a high risk of infection by Trichinella species. The parasite prevalence was high in the species that combined different feeding habits, i.e. they acted as predators, scavengers and cannibals. A relatively long life expectancy also contributed to a higher risk of infection. A relatively high parasite prevalence of Trichinella in wild animals in the Primorsky Krai was caused by the high biological diversity of carnivorans. Our results are important for understanding the trichinosis circulation in natural communities and the possibility of human infestation. These data are also important for managing the carnivorans' populations in the Russian Far East. The issues of nature conservation in regard to the trichinosis circulation are also important for threatened animals, including Panthera tigris altaica.

“…Due to the size difference, it can be thought that hunting is not easy, if not impossible. Wild boar and deer, such as Cervus nippon (sika deer) and Capreolus pygargus (roe deer), were reported to be detected from the feces of leopard cats in the Russian Far East [ 11 ] and in Pakistan [ 13 ], too. These studies suggest that leopard cats may have scavenged the carcasses of these large animals, although there is no direct evidence presented.…”

“…Studies on predation and feeding behavior of leopard cats have been conducted in countries, such as Singapore [ 7 ], Malaysia [ 8 ], Thailand [ 9 , 10 ], Russia [ 11 ], Indonesia [ 12 ], Pakistan [ 13 ], India [ 14 ], Cambodia [ 15 ], Laos [ 16 ], Korea [ 17 ], and Japan [ 18 , 22 ]. In these studies, prey items were identified by direct observation of hunting [ 12 ], observation of stomach contents [ 18 ], and microscopic observation of hair, teeth, feathers, toenails, and bones contained in collected fecal samples [ 7 – 11 , 13 – 17 ]. However, these methods require not only labor and time, but also expertise in morphology and osteology.…”

Combining vertebrate mitochondrial 12S rRNA gene sequencing and shotgun metagenomic sequencing to investigate the diet of the leopard cat (Prionailurus bengalensis) in Korea

The leopard cat (Prionailurus bengalensis), an endangered species in South Korea, is a small feline widely distributed in Asia. Here, we investigated the diet of leopard cats in the inland areas of Korea by examining their fecal contents using vertebrate mitochondrial 12S rRNA gene sequencing and shotgun metagenomic sequencing. Shotgun metagenomic sequencing revealed that the feces were rich in DNA not only of vertebrates but also of arthropods and plants, but care should be taken when using shotgun metagenomic sequencing to identify vertebrates at low taxonomic levels (e.g., genus level), as it was often erroneous. Meanwhile, vertebrate mitochondrial 12S rRNA gene sequencing was found to be accurate in the genus-level identification, as the genera identified were consistent with the Korean fauna. We found that small mammals such as murids were their main prey. By using these two sequencing methods in combination, this study demonstrated that accurate information about the overall dietary content and vertebrate prey of leopard cats could be obtained. We expect that the continued community efforts to expand the genome database of wildlife, including vertebrates, will alleviate the problem of erroneous identification of prey at low taxonomic levels by shotgun metagenomic sequencing in the near future.

We present the first documented evidence of interactions between the leopard cat (Prionailurus bengalensis euptilurus) and the invasive coypu (Myocastor coypus) in South Korea, captured through camera traps in Hwapocheon wetland park from May 2015 to April 2017. Two interactions were recorded: one showing a leopard cat carrying a carcass of sub‐adult coypu and the other a 4‐min sequence of predation and defense between two species. The observed interactions indicate active predatory behavior by the leopard cat against coypus and cooperative defense by coypus. These findings shed new light on predator–prey dynamics, highlighting the leopard cat's potential role as a predator of coypus and coypus' defensive abilities. Understanding these relationships could facilitate more effective management of invasive species and offer broader implications for ecosystem dynamics and conservation strategies.
