HistoryThis section has been translated automatically.

Lomholt, 1918

DefinitionThis section has been translated automatically.

Worldwide occurring mite disease of the Cheyletiellidae family, which is transmissible from animal to human, whose primary hosts are small mammals. S.a.among mites.

PathogenThis section has been translated automatically.

Cheyletiella (fur mites), 5 species (in dog, cat, rabbit, hare). Fur mites are permanent ectoparasites of mammals that do not bury themselves in the skin. The mites are 0.5 mm in size, they are whitish in colour and have stinging mouth limbs. If the domestic animals are heavily infested, the fur can appear mealy and whitish due to the masses of nits that are stuck on them.

ClassificationThis section has been translated automatically.

Of importance for humans are:

  • Cheyletiella parasitivorax (rabbit)
  • Cheyletiella yasguri (dogs)
  • Cheyletiella blakei (cats)
  • Cheyletiella furmani (rabbit)
  • Cheyletiella strandmanni (rabbits)

LocalizationThis section has been translated automatically.

Stem, chest area, groin region - often where there has been intensive contact with the sick pet.

Clinical featuresThis section has been translated automatically.

Irregularly distributed, sometimes also grouped, urticarial or maculopapular, rarely vesicular, strongly itchy efflorescences at contact points. Significant increase in itching with bed heat.

DiagnosisThis section has been translated automatically.

Detection of eggs and mites in the fur of domestic animals by removal by means of Sellotape (pathogens stick to the Sellotape strip); strip is stuck on a slide and examined nativ-histologically.

General therapyThis section has been translated automatically.

Spontaneous healing within 1-3 weeks, as mites can only survive for a few days in the absence of a human host (female mites for a maximum of 10 days).

Infested animals and their roost should be treated with insecticides, e.g. with acaricide (veterinary treatment).

External therapyThis section has been translated automatically.

To accelerate the healing process Externa containing glucocorticoids such as 1% hydrocortisone lotio, e.g. R123 or, if necessary, the more effective 0.1% hydrocortisone-17-butyrate cream (e.g. Laticort®).

Bland therapy with Lotio alba can also be helpful.

Only in cases of persistent itching the alternating combination of a glucocorticoid externum with an acaricide (e.g. from the group of pyrethroids e.g. 5% permethrin cream) is recommended.

Internal therapyThis section has been translated automatically.

In case of severe itching antihistamines such as Desloratadine (Aerius 1-2 tbl/day) or Fexofenadine (Telfast 1 tbl/day), if necessary internal treatment with Ivermectin 0.2-0.3 mg/kg bw p.o. as ED. Repeat the one-time therapy 3 times in intervals of 14 days.

Progression/forecastThis section has been translated automatically.

Spontaneous healing within 1-3 weeks.

Note(s)This section has been translated automatically.

It is important to treat the infected animals, as there is a risk of reinfection.
