In this study, we tried to detect protozoan blood parasites from the liver or blood of 156 Japanese black bears (Ursus thibetanus japonicus) in Iwate Prefecture of Japan by polymerase chain reaction. Two amplicons (approximately 540 bp and 480 bp) were detected by amplification for V4 hyper-variable regions of the 18S rRNA gene.Approximately 540-bp products were obtained in 119 samples (76.3%) and were considered to be DNA of Hepatozoon ursi. Approximately 480-bp products were obtained in 22 samples (14.1%) and were considered to be DNA of Babesia species. A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT

Systematic revision of the adeleid haemogregarines, with creation ofBartazoonn. g., reassignment ofHepatozoon argantisGarnham, 1954 toHemolivia, and molecular data onHemolivia stellata

Life cycles and molecular data for terrestrial haemogregarines are reviewed in this article. Collection material was re-examined: Hepatozoon argantis Garnham, 1954 in Argas brumpti was reassigned to Hemolivia as Hemolivia argantis (Garnham, 1954) n. comb.; parasite DNA was extracted from a tick crush on smear of an archived slide of Hemolivia stellata in Amblyomma rotondatum, then the 18S ssrRNA gene was amplified by PCR. A systematic revision of the group is proposed, based on biological life cycles and phylogenetic reconstruction. Four types of life cycles, based on parasite vector, vertebrate host and the characteristics of their development, are defined. We propose combining species, based on their biology, into four groups (types I, II, III and IV). The characters of each type are defined and associated with a type genus and a type species. The biological characters of each type are associated with a different genus and a type species. The phylogenetic reconstruction with sequences deposited in the databases and our own new sequence of Hemolivia stellata is consistent with this classification. The classification is as follows: Type I, Hepatozoon Miller, 1908, type species H. perniciosum Miller, 1908; Type II, Karyolysus Labbé, 1894, type species K. lacertae (Danilewsky, 1886) Reichenow, 1913; Type III Hemolivia Petit et al., 1990, type species H. stellata, Petit et al., 1990; and Type IV: Bartazoon n. g., type species B. breinli (Mackerras, 1960).

“…There are few reports of Hepatozoon isolates from wild mammals in Japan. Hepatozoon ursi has been reported in the Japanese black bear Ursus thibetanus japonicus ( Uni et al, 2003 , Kubo et al, 2008 ), H. felis in the Iriomote cat Prionailurus bengalensis iriomotensis ( Sakuma et al, 2011 ), and unidentified Hepatozoon spp. in the Hokkaido brown bear Ursus arctos yesoensis ( Kubo et al, 2010 ), the Ezo red fox Vulpes vulpes schrencki ( Maeda et al, 1982 ), the Tsushima leopard cat Felis bengalensis euptilura ( Kubo et al, 2006 ), the Northern red-backed vole Myodes rutilus and the large Japanese field mouse Apodemus speciosus ( Moustafa et al, 2017 ), the Japanese marten Martes melampus ( Yanai et al, 1995 ), and the Iriomote cat ( Kubo et al, 2006 ).…”

Hepatozoon apri n. sp. is described from Japanese wild boars Sus scrofa leucomystax in Japan. The gamonts in the peripheral blood leukocytes were 11.6 ± 1.4 × 6.7 ± 1.3 μm in size. The meronts in the muscle tissues were 35.0–47.5 μm in length and 26.5–30 μm in width. A high rate (53.0%) of infection was found by nested PCR using muscle specimens from 181 wild boars captured in Tokushima, Japan. A phylogenetic analysis based on 18S rRNA gene sequences revealed that H. apri n. sp. detected in wild boars is closely related to Hepatozoon spp. isolated from carnivores. This is the first description of a species belonging to the genus Hepatozoon detected in ungulates.
