| sarcoptes scabiei infestation misdiagnosed and treated as langerhans cell histiocytosis. | the inflammatory cell infiltrate in sarcoptes scabiei infestations often includes langerhans cells. scabies infestations in children may mimic langerhans cell histiocytosis (lch) clinically as well. we report two children with scabies who were misdiagnosed clinically and histologically as lch and treated with systemic chemotherapy. scabies must always be ruled out in infants and children with eczematous eruptions and inflammatory infiltrates that include histiocytes on histologic examination. | 2004 | 14871329 |
| ectoparasites--the underestimated realm. | context: ectoparasitoses (infestations with parasites that live on or in the skin) can cause considerable morbidity. whereas pediculosis and scabies are ubiquitous, cutaneous larva migrans and tungiasis (sand-flea disease) occur mainly in hot climates. the prevalence of ectoparasitoses in the general population is usually low, but can be high in vulnerable groups. scientific knowledge on how to deal best with parasitic skin diseases in different settings is scanty, and evidence-based measures fo ... | 2004 | 15032237 |
| dermoscopy for the in vivo detection of sarcoptes scabiei. | we report the case of an 80-year-old patient who had intense pruritus which did not respond to a 3-month treatment with topical corticosteroids. on dermoscopy examination of the excoriations, we found the typical dermoscopic aspect of the scabies mite at a distance. dermoscopy allows identifying a triangular structure which corresponds to the anterior section of the mite including the mouth part and the 2 pairs of front legs. this aspect has been described as resembling a jetliner with its trail ... | 2004 | 15118379 |

| scabies: more than just an irritation. | human scabies, caused by skin infestation with the arthropod mite, sarcoptes scabiei, typically results in a papular, intensely pruritic eruption involving the interdigital spaces, and flexure creases. recent research has led to a reassessment of the morbidity attributable to this parasite in endemic communities, particularly resulting from secondary skin sepsis and postinfective complications including glomerulonephritis. this has led to studies of the benefits of community based control progra ... | 2004 | 15254301 |
| genetic epidemiology of sarcoptes scabiei (acari: sarcoptidae) in northern australia. | utilising three hypervariable microsatellite markers we have previously shown that scabies mites on people are genetically distinct from those on dogs in sympatric populations in northern australia. this had important ramifications on the formulation of public health control policies. in contrast phylogenetic analyses using mitochondrial markers on scabies mites infecting multiple animal hosts elsewhere in the world could not differentiate any genetic variation between mite haplotype and host sp ... | 2004 | 15157767 |
| first documentation of in vivo and in vitro ivermectin resistance in sarcoptes scabiei. | ivermectin is increasingly being used to treat scabies, especially crusted (norwegian) scabies. however, treatment failures, recrudescence, and reinfection can occur, even after multiple doses. ivermectin resistance has been documented for some intestinal helminths in animals with intensive ivermectin exposure. ivermectin resistance has also been induced in arthropods in laboratory experiments but, to date, has not been documented among arthropods in nature. we report clinical and in vitro evide ... | 2004 | 15206075 |
| skewed th1/th2 immune response to sarcoptes scabiei. | scabies is a contagious skin disease of humans and many other species of mammals. previous studies suggested that the balance between the th1 and th2 immune responses may influence the outcome of a scabies infestation in a sensitized host. therefore, in this study, we examined the t-helper cell cytokine profiles of splenocytes and lymph node cells in balb/c mice that were immunized with scabies extract (primary response), infested with scabies mites (primary response), or immunized and then infe ... | 2004 | 15357058 |
| outbreak of sarcoptic mange and malasseziasis in rabbits (oryctolagus cuniculus). | an outbreak of combined sarcoptes and malassezia spp. infection was diagnosed in a rabbitry. about 20 (4%) of 500 rabbits were affected. two 6- to 8-month-old female holland lops rabbits were submitted to the tifton diagnostic & investigational laboratory at the university of georgia for complete necropsy. gross lesions consisted of marked multifocal areas of alopecia, crusting, and dermatitis around the eye and on ears, nose, lips, neck, abdomen, feet, and external genitalia. histologic examina ... | 2004 | 15357325 |

| history, biology and control of sheep scab. | sheep scab is one of the oldest known diseases of sheep. it is caused by either of the mange mites psoroptes ovis (fig. 1 and cover) or sarcoptes scabiei. p. ovis causes irritation so intense that sheep become preoccupied with scratching, cease to feed and rapidly become emaciated. it should be eradicated on welfare grounds alone (fig. 2). | 1986 | 15462743 |
| population effects of sarcoptic mange in barbary sheep (ammotragus lervia) from sierra espuña regional park, spain. | the nonindigenous barbary sheep population (ammotragus lervia) of the sierra espuna regional park (murcia, spain) suffered an outbreak of sarcoptic mange between 1991 and 1995, which contributed to a population decrease of 86%. this study presents the results of two population surveys conducted in 1994 and 1999 based on the fixed point and itineraries method (fpi) and the excrement count (ec) method, as well as data from demographic estimates and clinical observations conducted by the regional a ... | 2004 | 15465713 |
| rapid quantitative assay for acaricidal effects on sarcoptes scabiei var. suis and otodectes cynotis. | brimer et al. (vet. parasitol. 51: 123-135, 1993 and 59: 249-255, 1995) developed a migration assay for acaricidal effect of acetylcholinesterase inhibitors and macrocyclic lactones utilising sarcoptes scabiei var. suis mites. in contrast to many others, this assay is fully quantitative but quite time-consuming. the aim of the present investigation was to modify this assay to become faster and simpler. as a result accurate determinations can now be obtained within 6h, as opposed to 24h. furtherm ... | 2004 | 15285140 |
| biotin-avidin amplified elisa for detection of antibodies to sarcoptes scabiei in chamois (rupicapra spp.). | scabies is a major threat to the well being of mountain-dwelling bovid hosts, rupicapra rupicapra and rupicapra pyrenaica. severe outbreaks are in progress over a significant part of their distribution area and resource managers demand improved methods to monitor, analyse and possibly forecast the spread and effects of scabies at the population level. an amplified capture enzyme-linked immunosorbent assay was developed to detect antibodies to sarcoptes scabiei in chamois (rupicapra spp.) serum. ... | 2004 | 15535959 |
| on the substantial variation in serological responses in pigs to sarcoptes scabiei var. suis using different commercially available indirect enzyme-linked immunosorbent assays. | two trials were carried out to compare the use of different enzyme-linked immunosorbent assays (elisas) for the detection of antibodies against sarcoptes scabiei var. suis. in the first trial, we employed four tests and 70 selected sera from a closed pig farm with sarcoptic mange. the sera were taken from the breeding area as well as from the finishing unit and compared with skin scrapings. the sarcoptes-elisa 2001 yielded the most positive results (88.58%), followed by the elisa of the national ... | 2004 | 15338288 |

| sarcoptic mange in raccoons in michigan. | sarcoptic mange is a cause of pruritic skin disease in domestic dogs and a wide range of wildlife species. we describe sarcoptic mange in free-ranging raccoons (procyon lotor). three adult raccoons from upper wayne county, michigan (usa), were captured, killed, and submitted for diagnostic evaluation. the animals were intensely pruritic, and two had advanced alopecic and crusting lesions over their dorsum and hind limbs. skin scrapings and skin biopsies revealed crusting and hyperkeratotic derma ... | 2004 | 15362840 |
| scabies: new future for a neglected disease. | scabies is a disease of global proportions in both human and animal populations, resulting from infestation of the skin with the "itch" mite sarcoptes scabiei. despite the availability of effective chemotherapy the intensely itching lesions engender significant morbidity primarily due to secondary sepsis and post-infective complications. some patients experience an extreme form of the disease, crusted scabies, in which many hundreds of mites may infest the skin causin severe crusting and hyperke ... | 2004 | 15504541 |
| norwegian scabies in the immunocompromised patient. | norwegian, or crusted, scabies can be defined as a generalized severe scabies (sarcoptes scabiei var. hominis) infestation usually affecting the immunocompromised patient that is most commonly seen with the leukemia-lymphoma group of neoplasms. the diagnosis is commonly missed, which can lead to mismanagement. we describe a patient with norwegian scabies involving the lower extremities. the patient circumstances and treatment, as well as a review of the literature, are presented. the diagnosis o ... | 2004 | 15547127 |
| the effect of antimicrobial growth promoter withdrawal on the health of weaned pigs in finland. | the use of the antimicrobial growth promoters (agps) carbadox and olaquindox has been banned in the european union (eu) since september 1999. we studied the effects of the withdrawal on the health of weaned piglets on two types of piglet-producing farms (farrowing herds and farrow-to-finish herds) from the different regions of finland. farms with no major problems with post-weaning diarrhoea were selected for the study to better evaluate the effect of agps alone. data on production, medication a ... | 2004 | 15579342 |
| functional analysis and localisation of a delta-class glutathione s-transferase from sarcoptes scabiei. | the mite sarcoptes scabiei causes sarcoptic mange, or scabies, a disease that affects both animals and humans worldwide. our interest in s. scabiei led us to further characterise a glutathione s-transferase. this multifunctional enzyme is a target for vaccine and drug development in several parasitic diseases. the s. scabiei glutathione s-transferase open reading frame reported here is 684 nucleotides long and yields a protein with a predicted molecular mass of 26 kda. through phylogenetic analy ... | 2004 | 15619514 |
| prevalence, risk factors and economic importance of infestations with sarcoptes scabiei and haematopinus suis in sows of pig breeding farms in hesse, germany. | a cross-sectional survey was performed in 110 randomly selected pig-breeding farms of southern hesse, germany to estimate the prevalence of ectoparasite infestations and to find possible risk factors. ear scrapings of, if available, 10 sows per farm were examined for sarcoptes scabiei var. suis (de geer) (acaridida: sarcoptidae) by the potassium hydroxide digestion method, and a total of 2754 sows was inspected for skin lesions and infestations with haematopinus suis (l.)

| ectoparasitic sexually transmitted diseases: scabies and pediculosis. | scabies and pediculosis are diagnosed on an almost daily basis in many dermatology offices. whether the patient seeks medical attention because of the often unbearable itch of scabies or because of the fear of lice infestations, the physician should be on the lookout for these ectoparasitic infestations. secondary bacterial infection, resistance to medication, and the risk of spread of the infestations to family members and other close contacts may complicate the problem. patients frequently hav ... | 2004 | 15596323 |
| analysis of sarcoptes scabiei finds no evidence of infection with wolbachia. | the endosymbiont wolbachia has been detected in a range of filarial nematodes and parasitic mites and is known to affect host reproductive compatibility and potentially evolutionary processes. pcr of wolbachia surface protein (wsp), ftsz and 16srrna genes from individual sarcoptes scabiei mites obtained from a series of individual hosts, and database searches of an s. scabiei var. hominis est library failed to detect wolbachia genes. therefore, wolbachia appears not to be involved in the genetic ... | 2004 | 15710433 |
