Kort fortalt

Canine distemper is a highly contagious, severe viral disease affecting dogs and ferrets. It attacks multiple body systems, including the respiratory, gastrointestinal, and nervous systems, often leading to irreversible neurological damage. Understanding its signs, diagnostic process, and the critical importance of vaccination is essential for every pet owner.

Canine distemper is a highly contagious viral disease that causes severe lethargy and systemic illness.

TL;DR. Svært smittsom, livstruende virusinfeksjon hos hund og ilder med skade på luftveier, mage-tarm og nervesystem; ofte permanente nevrologiske følgetilstander.

Alvorlig systemisk sykdom med uttalt letargi.

Hva er det?

Morbillivirus (CDV). Rammer lymfoid, nervøst og epitelvev. Faser: lymfopeni/feber, deretter luftveier/GI/hud/øyne, ofte CNS. Ingen kurerende antiviral.

Årsaker og risikofaktorer

Aerosol og kroppsvæsker.

"CDV is shed in respiratory secretions for up to 90 days after infection. Initial replication of CDV is in lymphoid tissue, and viral destruction of lymphocytes results in lymphopenia and pyrexia."

Uvaksinerte valper 6-12 uker høyest risiko; ildere nesten 100% dødelig. Ingen rasepredisposisjon.

Tegn

  • Myoklonus (kardinal)
  • Vanlige: feber, depresjon, mukopurulent neseutflod, hoste, oppkast/diaré, pustler, hyperkeratose (hard pad), kramper, ataksi
  • Iblant: uveitt, optikusnevritt, KCS, emaljehypoplasi

A close-up of a dog's thickened, cracked paw pads.
Hyperkeratose av tredeputer er klassisk.

Diagnostikk

CBC (lymfopeni), thoraxrøntgen, konjunktivalcytologi, RT-PCR (gullstandard), IHC, av og til CSF.

A digital X-ray monitor displaying a dog's chest radiograph.
Thoraxrøntgen vurderer sekundær pneumoni.

Behandling

Kun støttende: IV-væske, antibiotika mot sekundærinfeksjon, respirasjonsstøtte, antiemetika, antikonvulsiva. Glucocorticoids selektivt. Streng isolasjon.

Prognose

Ofte dårlig, særlig ved CNS-tegn.

"CNS disease is generally progressive and carries a poor prognosis; it can develop in some dogs that never had systemic signs of disease recognized."

Forebygging

Core-vaksine valper + boostere; ilder-spesifikk vaksine; karantene; desinfeksjon.

Når ringe veterinær

Akutt: kramper/myoklonus; alvorlig åndenød; gulgrønn flod; kollaps; alvorlige GI-tegn; plutselig blindhet.
