the efficacy of showers for control of ectoparasites of sheep.ectoparasites of sheep in britain include the tick ixodes ricinus, the blowfly, lucilia sericata, the ked, melophagus ovinus and the lice, damalinia ovis and linognathus ovillus. the most important ectoparasite, however, is the mite psoroptes communis ovis which causes sheep scab. this notifiable disease was eradicated from britain in 1952 but was reported again in 1973. the control of ectoparasites depends largely on the efficient application of insecticide to the fleece and skin. plunge dippin ...197876363

a review of melophagus ovinus (l.), the sheep ked.the sheep ked melophagus ovinus is a member of the parasitic dipteran family hippoboscidae; it was a widespread ectoparasite of sheep that was of veterinary importance until the introduction of effective pesticides. since then it has become of less concern and may have become a relatively uncommon species through much of its former range. changes in agricultural practice, both greater intensification and development of more extensive systems (including organic farming and conservation grazing), ...200515893081
role of hippoboscidae flies as potential vectors of bartonella spp. infecting wild and domestic ruminants.the putative role of biting flies in bartonella transmission among ruminants was investigated. amplification of the bartonella citrate synthase gene from 83 hippoboscidae was detected in 94% of 48 adult lipoptena cervi flies, 71% of 17 adult hippobosca equina flies, 100% of 20 adult melophagus ovinus flies, and 100% of 10 m. ovinus pupae. our findings suggest that hippoboscidae play a role in the transmission of bartonella among ruminants. the vertical transmission of bartonella in m. ovinus and ...200415466580

immunological responses to parasitic arthropods.parasitic arthropods are responsible for enormous economic losses to livestock producers throughout the world. these production losses may range from simple irritation caused by biting and non-biting flies to deaths and/or damage to carcass, fleece, or skin resulting from attack by myiasis flies. the estimated costs of these losses are colossal but even these usually include only direct losses and ignore those associated with pesticide application. in the usa alone (in 1976), these losses were c ...198715462916

records of ectoparasites on humans and sheep from viking-age deposits in the former western settlement of greenland.during recent archaeological excavations in viking greenland, specimens of the human flea, pulex irritans l., and the body louse, pediculus humanus humanus l., were recovered from several farmsteads. bovicola ovis (schrank) and the sheep ked, melophagus ovinus (l.), also were found in associated deposits. the specimens were dated from about ad 990 to ad 1350. these finds raise questions about the levels of hygiene of the viking farmers and open some interesting medical and biogeographical conund ...19902201769
arsenophonus and sodalis symbionts in louse flies: an analogy to the wigglesworthia and sodalis system in tsetse flies.symbiosis between insects and bacteria result in a variety of arrangements, genomic modifications, and metabolic interconnections. here, we present genomic, phylogenetic, and morphological characteristics of a symbiotic system associated with melophagus ovinus, a member of the blood-feeding family hippoboscidae. the system comprises four unrelated bacteria representing different stages in symbiosis evolution, from typical obligate mutualists inhabiting bacteriomes to freely associated commensals ...201526150448
trypanosoma melophagium from the sheep ked melophagus ovinus on the island of st kilda.summarythe sheep ked has been largely eradicated in the uk but persists in the feral soay sheep of st kilda in the outer hebrides. sheep keds transmit trypanosoma melophagium, but parasitaemias are typically cryptic and this trypanosome has not been recorded in the st kilda sheep. trypanosomes were detected by pcr in preserved keds and were also found in gut smears from live keds; one infected gut was used to establish the trypanosome in vitro. examination of the morphology of bloodstream forms ...201020546642
microbial population analysis of the midgut of melophagus ovinus via high-throughput sequencing.melophagus ovinus, one of the most common haematophagous ectoparasites of sheep, can cause anaemia and reductions in weight gain, wool growth and hide value. however, no information is available about the microfloral structure of the midgut of this ectoparasite. in the present study, we investigated the microbial community structure of the midgut contents of fully engorged female and male m. ovinus using illumina hiseq.201728793927
