A cross-sectional survey of the gut microbiome in zoo-housed herbivores: associations between taxonomic deviations and individual health status

Keita Kakisaka, Yurie Taya, Naoki Hayashi, Mohamed Abdallah Mohamed Moustafa et autres

The health management of zoo-housed animals is important. Although clinical examinations are essential for health monitoring of the animals, many of them exhibit noncooperative behavior during examinations. It is therefore necessary to develop noninvasive health monitoring tools. Gut microbiome analysis represents a …

Genomic signatures of native (Japanese) and introduced (Oceanian) populations of the Asian longhorned tick Haemaphysalis longicornis

Yuma Ohari, Kodai Kusakisako, Mackenzie L. Kwak, Rika Umemiya‐Shirafuji et autres

Abstract The Asian longhorned tick (Haemaphysalis longicornis) impacts the health of humans, livestock, and wildlife, both as a parasite and a vector. Over more than a century, H. longicornis has become a widespread invasive species across much of the Asia-Pacific region, with …

Data on the efficacy of Echinococcus multilocularis cryopreservation and subsequent protoscolex development in cotton rats and infectivity in dogs

Hirokazu Kouguchi, Tomohito Koyano, Naoki Hayashi, Masahito Hidaka et autres

This dataset presents information on the viability of cryopreserved Echinococcus multilocularis (the Nemuro strain, Alaskan lineage) stored in liquid nitrogen. Protoscoleces and cyst residues were obtained from cotton rats experimentally infected with parasite eggs in the laboratory. These materials were mixed with …

A novel activation-related gene P158 is essential for evagination and early development of Echinococcus multilocularis protoscoleces

Zhendong Xin, Zhen Wang, Yong Fu, Chenye Jin et autres

BACKGROUND: Alveolar echinococcosis is a lethal zoonotic parasitic disease caused by Echinococcus multilocularis. The activation and subsequent evagination of protoscoleces (PSCs) in the host digestive tract are critical steps for establishing infection in definitive hosts, yet the underlying molecular mechanisms remain poorly …

Protoscolex Maturation in Echinococcus multilocularis Is Controlled by Host Genetic Factors Independent of Initial Development

Moe Kogawa, K. Sato, Teppei Nakamura, Naoki Hayashi et autres

Alveolar echinococcosis, caused by Echinococcus multilocularis, poses a serious public health concern. This parasite requires rodents as intermediate hosts for protoscolex maturation in the liver and subsequent transmission to definitive hosts. We aimed to identify the host genetic factors controlling protoscolex development …

Effectiveness of eprinomectin, albendazole and their combination therapy against strongyle nematode in dairy goats: A clinical field study using nemabiome-integrated approach in Thailand

Thanakorn Rompo, Naoki Hayashi, Takaya Hoketsu, Ernest Teo et autres

Strongyle nematodes are parasitic worms that significantly impact the health and productivity of livestock, including goats. Although infected goats are commonly treated with anthelmintics, reports of anthelmintic resistance have been increasing. This issue, along with limited treatment choices for goats and the …

Molecular diversity of tick-associated Rickettsia species in multiple provinces of Zambia

Yongjin Qiu, Martin C. Simuunza, Masahiro Kajihara, Joseph Ndebe et autres

Ticks harbor diverse Rickettsia spp., including several spotted fever group rickettsiae of veterinary and public health importance. However, information on tick-associated Rickettsia spp. in Zambia remains geographically limited. In this retrospective molecular survey, we examined 1,587 individual ticks collected from vegetation and …

Prevalence and egg surface morphology of capillariid nematodes in red foxes (Vulpes vulpes) from Hokkaido, Japan

Takashi Inoue, Yuta KANAI, Yuzaburo OKU, Nariaki Nonaka

Capillariid nematodes, such as Aonchotheca putorii, Eucoleus aerophilus, E. boehmi, and Pearsonema plica, parasitize canids. Reports about these nematodes parasitizing red foxes (Vulpes vulpes) in Japan are limited, and there are no prior records of E. boehmi. This study investigated 56 red …

Mitogenomics of the tropical bont tick Amblyomma variegatum reveals vertical and horizontal transmission of Rickettsia africae

Elisha Chatanga, Wessam Mohamed Ahmed Mohamed, Samuel Kelava, Naoki Hayashi et autres

BACKGROUND: The tropical bont tick Amblyomma variegatum, which is widespread in Africa and the Caribbean islands, is of both medical and veterinary importance as the principal vector of intracellular bacterial pathogens Ehrlichia ruminantium, causing heartwater in animals, and Rickettsia africae, causing African …
