| new zoonotic cases of onchocerca dewittei japonica (nematoda: onchocercidae) in honshu, japan. | zoonotic infections with onchocerca species are uncommon, and to date only 25 clinical cases have been reported worldwide. in japan, five previous zoonotic infections were concentrated in oita, kyushu (the southern island), with one previous case in hiroshima in the western part of honshu (the main island). the causative agent in japan was identified as onchocerca dewittei japonica uni, bain & takaoka, 2001 from japanese wild boars (sus scrofa leucomystax temminck, 1842). here we report two infe ... | 2015 | 25623081 |
| zoonotic filariasis caused by onchocerca dewittei japonica in a resident of hiroshima prefecture, honshu, japan. | a female of onchocerca sp. was found to be the probable causative agent of a subcutaneous nodule in the left knee of a 70-year-old man in a rural area of hiroshima prefecture, honshu, the main island of japan. we compared the characteristics of the agent with the features of the four previously suspected species found in cattle and horses in various parts of the world, as well as o. lupi and o. jakutensis that were suspected or proved, respectively, in zoonotic cases in europe. in addition, the ... | 2010 | 20561913 |
| molecular identification of infective larvae of three species of onchocerca found in wild-caught females of simulium bidentatum in japan. | wild female black flies attracted to a man or an idling automobile were collected at oita, japan where five cases of zoonotic onchocerciasis had occurred. among the five simulium species captured, 2% of simulium bidentatum, the predominant species, were infected with filarial larvae. there were at least two types of infective larvae, types a and b, based on morphometric observation. moreover, molecular analysis of the mitochondrial cytochrome c oxidase subunit 1 (co1) gene revealed that types a ... | 2010 | 20387737 |
| an onchocerca species of wild boar found in the subcutaneous nodule of a resident of oita, japan. | histological examination and dissection of a subcutaneous nodule removed from the right infraclavicular region of a 69-year-old woman from oita, kyushu, japan, revealed a young female of onchocerca dewittei japonica, a common parasite of wild boar in the oita region. distinctive morphologic characteristics of this onchocerca species include the thick cuticle with very prominent and straight transverse ridges overlapping at the lateral sides, the lack of inner striae (scalloping) of the inner cut ... | 2005 | 15710557 |

| a new case of zoonotic onchocercosis in northern kyushu, japan. | a case of zoonotic onchocercosis has been found in a resident who lived in iizuka city, fukuoka prefecture, japan for some time. a 24-year-old male developed a painful nodule on the middle finger of his right hand. the nodule was surgically removed from the vagina fibrosa tendinis of the finger at beppu medical center, beppu city, oita prefecture in 2012. the causative agent was identified as a female onchocerca dewittei japonica based on its histopathological characteristics. the identity of th ... | 2015 | 26209456 |
| onchocerca takaokai n. sp. (nematoda: filarioidea) in japanese wild boars (sus scrofa leucomystax): description and molecular identification of intradermal females. | human zoonotic onchocercosis is caused by onchocerca dewittei japonica, parasitic in wild boars (sus scrofa leucomystax) in japan. previously, microfilariae longer than those of onchocerca dewittei japonica were observed in skin snips from wild boars during the study of o. dewittei japonica. moreover, the third-stage larvae (l3) of these longer microfilariae were obtained from the blackfly simulium bidentatum after experimental injections. based on morphometric and molecular studies, similar l3 ... | 2015 | 26165205 |
| onchocerca dewittei japonica n. subsp., a common parasite from wild boar in kyushu island, japan. | we describe onchocerca dewittei japonica n. subsp. from the japanese wild boar, sus scrofa leucomystax, in oita, kyushu island, where all seven animals examined were found to be infected. this study began with efforts to identify the causative species in a recent case of zoonotic onchocerciasis. compared with onchocerca dewittei dewittei from sus scrofa jubatus in malaysia, which was reexamined here, our new subspecies has much greater space between the ridges on the females. in addition, its mi ... | 2001 | 11584751 |
