Wild raccoon dogs (Nyctereutes procyonoides koreensis) may play a role transmitting several pathogens to humans and pet animals. Information concerning the incidence of rabies, canine distemper virus (CDV), canine parvovirus (CPV), canine adenovirus type 2 (CAdV-2), canine parainfluenza virus type 5 (CPIV-5), and canine herpesvirus (CHV) is needed in wild raccoon dogs. In total, 62 brain samples of raccoon dogs were examined for rabies virus (RABV) and CDV, and 49 lung samples were screened for CDV, CAdV-2, CPIV-5, and CHV. No RABV, CAdV-2, CPIV-5, or CHV was identified, but nine CDV antigens (8.1%, 9/111) were detected. Moreover, 174 serum samples from wild raccoon dogs were screened for antibodies against the five major viral pathogens. The overall sero-surveillance against CDV, CPV, CAdV-2, CPIV-5, and CHV in wild raccoon dogs was 60.3%, 52.9%, 59.8%, 23.6%, and 10.3%, respectively. Comparisons of the sero-surveillance of the five pathogens showed that raccoon dogs of Gyeonggi province have slightly higher sero-positive rates against CDV, CPV, and CHV than those of Gangwon province. These results indicate high incidences of CDV, CPV, and CAdV-2 in wild raccoon dogs of two Korean provinces and a latent risk of pathogen transmission to companion and domestic animals.

The African swine fever virus (ASFV) remains contagious for a long time, not only in the carcass, but also in the bone marrow of an infected animal. The scavenging activity of various animals on ASFV-infected carcasses is a likely risk factor for ASFV transmission. Thus, we conducted this study to determine whether scavengers are potential vectors for ASFV. In nonprotected wild boar carcasses on the forest floor, we investigated the seasonal patterns of carcass decomposition and scavenger visits for feeding on them. The duration from fresh to early skeletonization (only bones and leather remaining) of adult carcasses was 37.6±23.1 days (n=3, range=11-51 days) in winter. The duration from fresh to later skeletonization (only bones and some fur remaining) of all carcasses, including subadult carcasses, was 8.3±2.5 days (n=4, range=7-12 days) in summer. At all three study sites, leopard cats (30.3%), large-billed crows (21.6%), and golden eagles (18.1%) were the frequently visiting species, representing more than 10% of the total visits (343 visits) in winter, whereas raccoons (21.9%), grey-backed thrushes (39.4%), and eyebrowed thrushes (14.7%) were the most frequent visitors in summer. In winter, crows or cinereous vultures were the first animals to arrive at a carcass; in summer, raccoons or crows arrived first. Our results showed that wild boars, raccoons, and leopard cats relatively frequently visited wild boar carcasses and stayed there for a long time. Wild rodents chewing on or staying near carcasses were photographed during winter. In addition to wild boars, thus, mammals, such as raccoons, leopard cats and rodents, and birds, such as accipitrids and thrushes, may be spreaders of ASFV in South Korea.

인구증가와 산업의 발달로 고속도로, 국도, 철도 등의 개발에 의한 생태계 절단이 증가하여 이로 인한 야생돌물의 서식지 단편화 현상이 증가하였다. 그로 인하여 유해야생동물로 인한 피해가 속출하면서 국내서 금전적 보상을 통해 일부 피해 농가를 구제하는 등의 노력을 펼치고 있다. 하지만 피해사례 주민들은 이러한 야간순찰로 인해 밤잠을 자지 못하거나 기본적인 생활에 많은 어려움을 겪고 있다. 본 연구는 야생동물들의 생태와 습성에 대한 연구를 바탕으로 초음파 및 초저주파를 발생, 재생시켜 일정 범위 내 야생동물의 접근을 방지시키고 접근을 효과적으로 막을 수 있는 비연속적인 시스템에 대한 쿼드콥터를 연구 개발 하였다.

Tumor incidence in wild mammals is reportedly very low. Wild nutria, a large rodent, is known to carry many infectious diseases, but rarely exhibits neoplastic diseases. We necropsied a male wild nutria and found a large nodular mass in the left inguinal region, adjacent to the penis. Histopathologically, the mass was diagnosed as preputial gland adenoma. Spontaneous preputial gland adenomas are extremely rare in all animals. Moreover, reports of tumors in nutrias have been limited to adenocarcinomas of the lungs and uterus, as well as subcutaneous fibromas. Here, we describe preputial gland adenoma in a wild nutria.

A study on the isolation of Yersiniae from the feces of wild animals(mammals 376, birds 19 and reptiles 13) in zoo and the biotype and serotype and susceptibility of 12 antibiotics was carried. Out of 408 animals, Yersiniae were isolated from 28 animals(6.9%). Of 28 isolates, 27 isolates(96.4%) were Y. enterocolitica and 1(3.6%) was Y. kristensenii. According to the species, 25(6.6%) of Y. enterocolitica and 1(0.3%) of Y. kristensenii were isolated from 376 mammals, 2(15.4%) of Y. enterocolitica from 13 reptiles but not isolated from 19 birds. According to the eating pattern, 8(5.2%) of Y. enterocolitica were isolated from 155 carnivora, 13(10%) of Y. enterocolitica from 123 herbivora, and 6(4.9%) of Y. enterocolitica and 1(0.8%) of Y. enterocolitica from 123 omnivora. Out of 27 isolates of Y. enterocolitica, all were biotype 1. And predominant serotype was 0:21(40.7%), and 0:5(37.0%), 0:6(11.1%), 0:1(3.7%), 0:9(3.7%) and untypable(3.7%). Yersiniae isolated from zoo animals were resistant to cephalothin(100%), ampicillin(96.4%), carbenicillin(96.4%) and tetracycline(14.3%) and streptomycin(3.6%) and susceptible to chloramphenicol(100%), colistin(100%), gentamicin(100%), kanamycin(100%), nalidixic acid(100%), polymyxin B(100%) and tobramycin(100%). The predominant multiple resistance pattern was Am-Cf-Cb(82.1%), and Am-Cf-Cb-Te(10.7%) and Am-Cf-Cb-Te-Sm(3.7%).

Due to the frequent occurrence of dangerous wild animals in rural or mountainous areas. it has been increasing damage of crops in every year. Fight bell or electric fence is typically installed to chase those wild animals. But there are problems that it is impossible to drive out birds and spends high installation and maintenance cost. In addition, it is inefficient to the risk of electric shock effect. In this study, the proposed system can drive out hazardous wildlife and birds regardless of installation location through realtime detection with the multi-sensing based IoT platform technology. This study showed a very large significance effect that can reduce crop damage by wildlife and birds.

The data on the forms and methods of hunting, the dynamics of the number of animals and the results of their production are given. For comparison, the acts of such a limiting factor as predators are specified. Reasons for the low number of wild ungulates are determined and main problems are formulated.

Pesticides are extensively used for the control of crop pests in agriculture and forestry. Organophosphate (OP) and carbamate pesticides are especially effective for the control of a variety of harmful insects. However, these cholinesterase inhibitors are also dangerous to non-target organisms (wildlife and other animals) because of their high acute toxicity. Most poisonings by pesticides occur as a result of misuse or accidental exposure, but intentional killing of unwanted animals also occurs. At the request of a local autonomous entity, we investigated wild bird poisonings by pesticides from 2003 to 2007. The 207 suspicious samples of pesticide poisoning based on the necropsy were analyzed by GC/NPD, GC/FPD, or GC/MSD. We looked for trends in the identification of pesticides in wild birds thought to have died from poisoning. Pesticides were determined in 59% of the total samples analyzed. Phosphamidon and monochrotophos were the most common pesticides identified, which amounted to 77% of the subtotal. Other OP and carbamate pesticides were also found in various concentrations from dead wild birds. The determined rates of pesticides were as high as 86% and 76% in 2003 and 2006, respectively, during an outbreak of avian influenza in Korea.

Recent studies revealed that many animals identify individual humans. In this account, we review previous literatures on individual human recognition by wild or domestic animals and discuss the three hypotheses: "high cognitive abilities" hypothesis, "close human contact" and "pre-exposure to stimuli" hypothesis. The three hypotheses are not mutually exclusive. Close human contact hypothesis is an ultimate explanation for adaptive benefits whereas high cognitive abilities and pre-exposure to stimuli hypothesis are proximate explanations for mechanisms to perform such discriminatory behaviour. We report a case study of two bird species in a human-free habitat. Long-tailed skuas, which are known for having high cognitive abilities, exhibited the human discriminatory abilities whereas ruddy turnstones did not display such abilities toward approaching humans. This suggests that highly intelligent species may have this type of discriminatory ability so that they could learn to identify individual humans quickly by pre-exposure to stimuli, even in a human-free habitat. Here, we discuss that human recognition is more common in species with rapid learning ability and it could develop for a short period of time between an intelligent species and human.
