pig handler's itch.forty-six humans who contacted pigs infested with sarcoptes scabiei were investigated. thirty (65.2%) had symptoms of sarcoptes scabies, and s. scabiei mites could be recovered from 20 (66.6%) skin scrapings. itching was the main symptom. people within the age group of 26-35 years were infested the most. hands and legs were the most common sites of the lesions, which subsided within 2-3 weeks when the infested pigs were treated and the intimate contact with the pigs was prevented.19902110554
sarcoptic mite hypersensitivity: a cause of dermatitis in fattening pigs at slaughter.the prevalence of sarcoptes scabiei in pigs in the netherlands, and the causal relationship between infestation and dermatitis in fattening pigs were assessed in a survey in 1988. in the first part of the survey 400 fattening pigs from 88 farms and 200 sows were examined. in the second part of the survey 193 fattening pigs with normal skin and 201 with dermatitis were examined; the dermatitis was characterised by small round, slightly thickened skin lesions, mostly on the rump, flanks, abdomen a ...19902111597
scabies.scabies is a mite infestation caused by sarcoptes scabiei. varieties of this organism can produce disease on 40 different species of animal, including humans. the organisms mature, burrow, and lay eggs. the newly hatched larvae mature and mate on the skin, causing itching and excoriated papules on humans, and mange, with crusts and oozing, on hair-bearing animals. treatment with the gamma isomer of hexachlorobenzene or with pyrethrins is effective. care must be taken that all infected or exposed ...19902112989
density of itch mite, sarcoptes scabiei (acari: sarcoptidae) and temporal development of cutaneous hypersensitivity in swine mange.experimental infestations of sarcoptes scabiei (de geer) were established to study development of cutaneous hypersensitivity in pigs. forty-eight pigs in six isolation rooms were used in two trials lasting 51 and 65 days, respectively. treatments of 0 (control), 100 (low dose), and 1000 mites (high dose) per pig were randomly assigned to rooms. intradermal skin tests with a sterile mite extract were done weekly to assess hypersensitivity. control pigs never responded to the extract, whereas most ...19902119083
use of ivermectin to control sarcoptic mange in goats in indonesia.the results of three experiments aimed at controlling sarcoptic mange in goats in indonesia are reported. in experiment 1 treatment with ivermectin (0.2 mg/kg body weight) or coumaphos (0.05% dip solution) resulted in a significant reduction in mite numbers and an increase in body weight while in the untreated controls all animals had to be withdrawn from the experiment due to severity of infection. in experiment 2 three treatment levels of ivermectin were shown to be equally effective in reduci ...19902120826
a technique for quantitative evaluation of ectoparasitic mites and insects of domestic animals.a modified koh dissolution technique using tween 80 has been developed for the diagnosis and quantitative evaluation of ectoparasitic mites and insects of veterinary importance. fifty intact skin segments from ten different domestic animals were artificially inoculated in vitro with ten specimens each of the mites sarcoptes scabiei, chorioptes bovis, psoroptes ovis and demodex caprae and insects haematopinus eurysternus and bovicola bovis. sixty-seven to 88% of the mites and 80-99% of the insect ...19902121422
dynamics of swine mange: a critical review of the literature.this paper summarizes the literature on swine mange, incorporating relevant literature on human scabies and on acarine associations with other mammals. discussed are how mite populations affect immune development, how immune hypersensitivity affects host behavior and performance, and how immune hypersensitivity determines whether or not crusted lesions develop. several key gaps in our understanding of swine mange are identified. the temporal pattern of immunity has not been studied beyond the 20 ...19902121987
sarcoptes scabiei in histopathologic sections of skin in human scabies.the usual methods of diagnosis remove sarcoptes scabiei from its habitat. thus, one has no appreciation of the host-endoparasitic interaction, especially the pathologic response of the surrounding tissue and the means by which the mite survives and lives its life cycle in the skin. the biopsy specimen described in this article demonstrates the tissue reaction that can be correlated with clinical symptoms. it also clearly depicts the actual position, morphological features, and developmental cycl ...19902122813
epidemiological studies of sarcoptic mange in tanzanian pig herds.an epidemiological survey of sarcoptic mange in 32 herds with a total herd size of 2,021 pigs was conducted in three representative climatic zones in tanzania. the disease was present in all zones in varying prevalences. the overall prevalences were 52% and 21% when determined on the basis of clinical examination and mite isolation respectively and 91% of the herds were shown to be harbouring the disease.19902126898
[intestinal parasites and ectoparasites in the v region, chile: study in the psychiatric hospital of putaendo].a prospective study was carried out in 229 chronic patients (of both sexes) from the psychiatric hospital of putaendo, in order to find out the frequency of intestinal parasites and/or commensals in the period 1987-1989. one hundred and ninety four (84.7%) out of the 229 studied patients were infected by parasites and/or commensals. the high prevalence of commensals entamoeba coli (55.0%) and endolimax nana (50.5%) became more evident. among the parasites, the most frequent was trichuris trichiu ...19902152365
the "nuisance" sexually transmitted diseases: molluscum contagiosum, scabies, and crab lice.although molluscum contagiosum, scabies, and infestation by crab lice do not carry the requirements of partner notification or other long-term consequences, they are among the most commonly reported sexually transmitted disease. molluscum contagiosum is a benign viral infection of the skin epidermal layer, most often transmitted by intimate skin-to-skin contact. the lesions often resolve spontaneously over time, but patient discomfort or social reasons may require destructive removal of the lesi ...19902246949
histopathology in hosts parasitized by sarcoptes scabiei.histopathologic evaluation of nondermal tissue in rabbits infested with sarcoptes scabiei var. canis was investigated. severe infestation resulted in deviant serological and serum biochemical values. histological study revealed structural changes in the tissues of specific organs. the most prominent histological finding was amyloidosis in the liver, glomerulus of the kidney, red pulp of the spleen, intestines, and tongue. hosts treated for infestation exhibited no abnormal organ histology.19902254824
care and treatment of scabies.in these days of universal precautions, the staff nurse can and should work with all patients as if they had a potentially infectious disease. a case in point is scabies which mimics many dermatological conditions and is transmitted by direct contact. scabies is caused by infestation with the mite sarcoptes scabiei, and can be a problem in nursing homes and hospitals, particularly among patients who are debilitated and require extensive hands-on care. a scabies outbreak need not result in chaos ...19902393498

experimental infection of the one-humped camel (camelus dromedarius) with sarcoptes scabiei var. cameli and s. scabiei var. ovis.camels were experimentally infected with sarcoptes scabiei var. cameli and s. scabiei var. ovis. the lesions produced by both mites were progressive and similar in extent and severity. the lesions produced by the mites spread mechanically through gnawing and scratching, and eventually covered most of the body of the host. skin scrapings from the experimental lesions contained many mites of all stages, proving that s. scabiei var. cameli and s. scabiei var. ovis became equally well established, r ...19862443090
what's wrong with this patient? 19892471250
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
responses of immunoglobulin-secreting cells in the skin of pigs during sarcoptes scabiei infestation.investigations using immunofluorescence and immunoperoxidase techniques revealed a gradual, but marked, increase in the numbers of immunoglobulin-secreting cells in the skin of pigs during the development of lesions of sarcoptic mange. this was followed by a marked decrease as the lesions regressed. the rise and fall in numbers of these immunoglobulin-secreting cells were observed in both newborn and older animals as they developed signs of cutaneous disease. igg-secreting cells were the major i ...19892529699

experimental infection of the domestic donkey (equus asinus asinus) with a goat strain of sarcoptes scabiei, and treatment with ivermectin.donkeys were experimentally infected with sarcoptes scabiei from goats, proving that this mite is not completely host specific. the lesions produced on the donkeys were characterized by extensive areas of alopecia, covered with thin crusts and bran-like scales. the skin had many excoriations but showed no cracks or fissures. skin scrapings from the experimental lesions in donkeys contained numerous mites of all stages and skin sections showed severe histopathological changes, proving that the go ...19852865877
norwegian scabies: occurrence in a patient undergoing immunosuppression.norwegian scabies is rare yet distinctive. the majority of reported cases have been in patients with relatively small group of diseases, including down syndrome and lepromatous leprosy. a case occurred in a patient on long-term immunosuppressive therapy following a kidney transplant. altered host factors appear to be the prime determinants in the pathogenesis of the disease.1976822784

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
