Although many trypanosomatids have been found in mammals and birds in Japan, information regarding their invertebrate host is currently lacking. During our virome analyses of ticks and horse ies, several trypanosoma-like sequences were found. Further sequence characterization and PCR-based screening revealed trypanosomatids termed Trypanosoma sp. 17ISK-T2 and 17ISK-T22 in the nymphs of Haemaphysalis ava, and T. theileri-like sequences in Tabanus ru dens. ese results indicate that virome analysis by next-generation sequencing (NGS) can also be used as a tool for protozoan detection from arthropods. Further investigations will assist in understanding the diversity and transmission dynamics of these parasites in Japan.","PeriodicalId":104111,"journal":{"name":"Medical Entomology and Zoology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114130495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diseases, zoonoses, and biosecurity are important emerging issues for species conservation at the world zoos. Zoos emphasize public health to protect visitors and zoo staff, and animal hygiene to manage the good health. There is no border between on a zoo ground and neighboring natural environment. Therefore, zoo biosecurity including preventive medicine protocols to protect the animals from infectious diseases transmitted by wildlife are routinely conducted. Infectious diseases of captive animals should be prevented to spread outside. Investigation of rescued wildlife and necropsies of the carcasses found on zoo grounds must be useful monitoring tools of wildlife diseases and provide a baseline measure of the risk by local wildlife. A sparrow mass mortality caused by emerging salmonellosis in Hokkaido, 2008 ‒ 2009. The initial case found dead on a zoo ground was investigated as a preventive medicine program to protect the captive animals and biosecurity. Zoos can work as wildlife disease information networks and an early warning system by monitoring wildlife diseases and conducting biosecurity countermeasures.","PeriodicalId":104111,"journal":{"name":"Medical Entomology and Zoology","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132760147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
