OBELISCOIDES CUNICULI (GRAYBILL), IN LAGOMORPHS, WOODCHUCKS AND SMALL RODENTS

The parasitic development of Obeliscoides cuniculi nsultistriatus NIeasutrcs ansc! Andersotu, 1983 tvas studied in Nesv Zealand ss'hite rabbits (Oryctolagus cuniculus). Thsmrt!-stagc larvae cxsbscathuetl svithmims 24 hr. The third molt occurred 3 days and the foutrth 8-11 days post-infectionm. All storms svcnc fifths stage 14 days post-infections. Males ss'erc matutre at 16 tlays anit! coputlation occutnnet! in 15-16 days. Feunales svene gravid at 18 days. The prepatent period ss'as 16-22 tlays. The patcmst peniot! svas 6 1-118 tla'ss anucl ussak's hived longer than females. All stages st'enc fount! in the mutcosa except tlse fifths svhich svas fouumtl lymnug omu the mucosal surface 'svithin a layer of mucuts. Petechiac 'svcnc the onily lesions sects iumexperimentally imsfectetl rabbits. Patent infections of 0. c. multistriatus 'svcre established expenimeustally in inufectet! svooc!chsutcks (Marmota monax), snosvshoe hares (Lepus americanus) and cottonstail rabbits (Sylvilagus floridanus). Patetst infections of 0. c. cuniculi 'svere established experimentally in snmost-shoc hares. Patent insfectionis of 0. c. multistriatus dit! umot appear in experimentally infected HPB ss'hitc (Sss-iss Webster) mice (Mus musculus), Wistar rats (Rattus norvegicus), H.O.R. F5 Syrian hamsters (Mesocricetus aural us), H.O.R. F smooths-huairetl guinea pigs (Cavia porcellus) and H.O.R. F gerbils (Meriones unguiculatus).
