Characterization of quinolone-resistant and extended-spectrum β-lactamase-producing Escherichia coli derived from sika deer populations of the Nara Prefecture, Japan.

Wildlife in urban areas have the potential to disseminate antimicrobial-resistant bacteria (ARB) across a wider environment. Using antimicrobial-supplemented agar plates, we isolated extended-spectrum β-lactamase-producing Escherichia coli (EEC) and quinolone-resistant E. coli (QREC) from 144, 23, and 30 deer feces from Nara Park (NP), rural area neighboring NP (RA), and Mt.

A historic religious sanctuary may have preserved ancestral genetics of Japanese sika deer ().

Deer have been a major resource for human populations for thousands of years. Anthropogenic activities, such as hunting, have influenced the genetic structure and distribution of deer populations. In Japan, wild Japanese sika deer () have been hunted since ancient times but have also been historically protected as sacred animals in several sanctuaries.

Clonal Spread of Quinolone-Resistant Escherichia coli among Sika Deer (Cervus nippon) Inhabiting an Urban City Park in Japan.

The emergence and dissemination of resistance to clinically important antimicrobials in wild animals is of great concern. The aim of our study was to reveal the prevalence and intraspecies dissemination of quinolone-resistant Escherichia coli (QREC) in sika deer (Cervus nippon) in Nara Park, a famous tourist spot in Japan. Fecal samples were collected from 59 wild deer in Nara Park between July and October 2018.

Redescription of Enterobius (Enterobius) macaci Yen, 1973 (Nematoda: Oxyuridae: Enterobiinae) based on material collected from wild Japanese macaque, Macaca fuscata (Primates: Cercopithecidae).

Enterobius (Enterobius) macaci Yen, 1973 (Nematoda: Oxyuridae: Enterobiinae) was collected from a Japanese macaque, Macaca fuscata, in Nara and Yamaguchi Prefectures, Honshu Island, Japan, for the first time. A redescription is presented along with DNA sequence data. This pinworm is a typical member of the subgenus Enterobius and is characteristic in the spicule morphology, being readily distinguished from other congeners.

The influence of Pleistocene refugia on the evolutionary history of the Japanese hare, Lepus brachyurus.

We performed a phylogeographic analysis of the Japanese hare, Lepus brachyurus, using the mitochondrial cytochrome b gene (1140 bp). In total, 119 haplotypes were recovered from 197 samples isolated from 82 localities on three main islands of the Japanese archipelago: Honshu, Sikoku, Kyushu, Sado Island and the Oki Islands. Results showed two distinct clades at a genetic distance of 3.

Ehrlichia chaffeensis infection of sika deer, Japan.

To determine whether Ehrlichia chaffeensis exists in Japan, we used PCR to examine blood from sika deer in Nara, Japan. Of 117 deer, 36 (31%) were infected with E. chaffeensis.

Local variation in diet composition of the Japanese serow during winter.

We investigated local geographical variation in the plant composition and quality (crude protein) of the diet of the Japanese serow (Capricornis crispus) by analyzing rumen contents. We collected the rumen contents from 111 Japanese serows culled for pest control between January and March 1997 in Shizuoka Prefecture, central Japan. The composition of the diet, characterized by a high proportion of browse (65.

A new rhabditoid nematode species in Asian sciurids, distinct from Strongyloides robustus in North American sciurids.

Strongyloides callosciureus n. sp. (Nematoda: Rhabditoidea), from Asian sciurids, is described based on morphology, morphometry, and the small and large subunit (SSU/LSU) ribosomal RNA gene (rDNA) sequences.

The stomal morphology of parasitic females of Strongyloides spp. by scanning electron microscopy.

For the discrimination of the species of the genus Strongyloides, the shape of the stoma in the apical view of parasitic females is the most important feature. Microscopical interpretations divided the shape of the stoma into four groups (simple, angular, complex, and simple but with esophageal teeth); however, the stomas classified in the latter two groups, in particular, remained unclear. In the present study, parasitic females of eight representative Strongyloides spp.
