Article Abstract

In Japan, the first patient with severe fever with thrombocytopenia syndrome was reported in Yamaguchi in 2012. To understand the severe fever with thrombocytopenia syndrome virus (SFTSV) infection in this region, a retrospective surveillance in sika deer and wild boars in Yamaguchi was conducted using a virus-neutralizing (VN) test. The result revealed that 510 of the 789 sika deer and 199 of the 517 wild boars were positive for anti-SFTSV antibodies. Interestingly, seroprevalence in sika deer increased significantly from 2010-2013 to 2015-2020. The SFTSV gene was detected in one of the 229 serum samples collected from sika deer, but not from wild boars. In conclusion, SFTSV had spread among wild animals before 2012 and expanded gradually around 2013-2015 in Yamaguchi.

Spent mushroom substrate (SMS) is abundant in nutrients, including polysaccharides, essential amino acids, dietary fiber (DF), and other bioactive compounds. The compound microorganism preparation (CMP), comprising multiple beneficial bacterial groups, is widely used as a feed additive to modulate intestinal microbiota and enhance nutrient absorption in animals. This study investigated the effects of supplementing young sika deer's concentrated feed with SMS and CMP on total intestinal digestibility, growth performance, serum immune indicators, biochemical parameters, and intestinal microbial composition.

Department of Infectious Diseases, Division of Parasitology, Faculty of Medicine, University of Miyazaki, Japan.

Fasciolosis is a major cause of food-borne parasitic zoonosis. It primarily affects ruminants but also infects humans. Clinically, it is characterized by abnormal liver images with prominent eosinophilia.

Sympatric species, commonly evolve behavioural mechanisms allowing them to coexist, thereby reducing direct competition for resources. In Japan, since the 1970s, the endemic Japanese serow (Capricornis crispus) and the sika deer (Cervus nippon) have been primarily allopatric. However, due to the rapid expansion of the sika deer population on Japan's main island of Honshu, the habitats of these two species now overlap.

Owing to agricultural expansion worldwide, agricultural crops can have major effects on the life history traits of wildlife. However, the functional role of crop consumption on the life history traits of long-lived mammals is seldom evaluated quantitatively. Body size is an important life history trait because it is directly related to fitness.

Sika deer, primarily animals of Japanese origin, have been introduced into Europe and, following release into the wild, established free-ranging populations in several countries, including Germany. In addition to the wild populations, sika deer are still maintained in deer parks and there are also deer farms carrying sika deer for venison production. However, to date there is no information about the parasite fauna that infect farmed sika deer and only little knowledge on parasites of sika deer in parks.
