biology, host relations, and epidemiology of sarcoptes scabiei.scabies continues to be an important parasitic disease of humans, and other mammals. suprisingly for a disease that has afflicted humans since antiquity, little is directly known about the basic biology of the parasite, the host-parasite interactions, the host immune response, and host susceptibility. much more research in these areas is needed if we are to understand fully the occurrence, transmission, and epidemiology of both human and animal scabies.19892494934
efficacy of ivermectin against live mites and eggs of sarcoptes scabiei in pigs.sows infested with sarcoptes scabiei var. suis (ssvs) were treated with 75, 150 and 300 micrograms/kg of ivermectin by a single subcutaneous injection at the neck region. compared to the numbers of mites and eggs just before injection, those on post treatment weeks (ptw) 1, 2 and 4 showed significant decreases. especially at 300 micrograms/kg, the counts showed almost all mites and eggs were eradicated on ptw 1, manifesting ivermectin to possess potential effect on ssve without apparent abnormal ...19892514317
scanning electron microscopy of sarcoptic mange lesions in swine.scanning electron microscopy revealed that lesions of sarcoptic mange in swine, pass through 3 different stages. during the first 3 weeks of infestation, adult female mites tunnel into the epidermis. during the following 3 or 4 weeks, the surface openings of these tunnels become covered with keratinized epidermal crust which increases in thickness. after 7 weeks of infestation, the crust falls off, the tunnel openings become apparent again and most of the mites vacate these tunnels.19892527435

mites in the environment of cases of norwegian scabies.three cases of norwegian scabies diagnosed in glasgow hospitals within 1 year each caused wide-spread outbreaks of papular eruptions amongst the patients and staff, followed later by a few cases of classical scabies. symptoms and timing suggested that these infections were caused by immature mites derived by personal contact and possibly by contact with infected cuticular fragments which were abundant in the environment of the three patients. to control a ward epidemic, isolation of the norwegia ...1975807230
the effect of sarcoptic mange on growth performance, leukocytes and lymphocyte proliferative responses in pigs.the effects of a single artificial infestation with sarcoptic mite (sarcoptes scabiei var. suis degeer) on weight gain and lymphocyte blastogenic responses were studied in untreated and fenvalerate-treated pigs. average daily feed intake, average daily gain and feed efficiency were monitored for 5 weeks in 32 infested and 16 uninfested pigs. total and differential leukocyte counts were determined and lymphocyte proliferative responses, using a mitogen-stimulated lymphocyte blastogenesis assay, w ...19863105158

[the seasonality of scabies morbidity and the fertility of the itch mite sarcoptes scabiei de geer as an index of the activity of a population of the causative agent].the authors analyze the features of the epidemic process in scabies and review foreign and soviet literature on the seasonal pattern of this condition. they have introduced the mite fertility index, that is determined by the number of eggs in the mite burrow, counted with the use of a new laboratory diagnostic technique with lactic acid. the studies have revealed that this index is high in september-december (11.5 +/- 1.0 - 12.6 +/- 1.3) and much lower in january-july (8.9 +/- 1.1 - 6.0 +/- 0.6) ...19892515675
norwegian scabies in a patient with aids.depression of cellular and humoral immunity can result in an overwhelming infection with the mite sarcoptes scabiei. infections in which the densities of mites are very high are known as norwegian, or crusted, scabies. cases of norwegian scabies have been reported sporadically in patients with aids, but the appearance of the rash on these patients can be very misleading because of the diffuse papular or psoriasiform presentation. such patients may readily transmit scabies to others. since the di ...19921571423
