Borna is 'n virussiekte wat by perde (en ander warmbloedige diere) voorkom. Dit is eers in Duitsland in perde ontdek, en dit is hoofsaaklik 'n siekte wat vandag in Europese en Midde-Oosterse lande voorkom. Dit is nie bekend dat dit tans in die Verenigde State is nie.

Die Borna-siektevirus (BDV) veroorsaak neurologiese probleme en is dodelik by baie perde. Perde sowel as skape en ander plaasdiere is 'n natuurlike gasheer vir hierdie virus, maar ander diere soos knaagdiere kan aangetas word.

Simptome en soorte

Die kliniese tekens van Borna-virus is soortgelyk aan ander ensephalitiese perde. Die inkubasietyd is relatief lank en kan ses maande duur vanaf infeksie totdat kliniese tekens verskyn. Dit is as gevolg van die stadige beweging van die virus langs neurone.

• Lusteloosheid
• Swak koördinasie
• Blindheid
• Swakheid
• Verlamming
• Inval
• Vreemde gedrag (byvoorbeeld kopdruk of in donker hoeke aangetref)

Oorsake

Die wyse van virale oordrag is nog onbekend, maar word vermoedelik via inaseming of inname. Daar word ook vermoed dat daar bosluise oorgedra word, asook die verspreiding van die virus via trekvoëls.

Diagnose

Definitiewe diagnose van Borna-virusinfeksie op 'n lewendige perd is moeilik. Monsters van serebrale spinale vloeistof (CSF) toon slegs resultate wat tipies is vir baie verskillende aansteeklike neurologiese toestande en kan nie Borna-virus spesifiek onderskei nie. Na die dood kan monsters van die sentrale senuweestelsel na laboratoriums gestuur word vir verdere ondersoek en identifisering van die Borna-virus wat op hierdie stadium gemaak is.

Behandeling

Daar is tans geen spesifieke behandeling vir BDV nie. Daar is egter studies gedoen om die virus te isoleer en daar word gevorder met beter behandelingsopsies. As 'n perd in die VSA met hierdie siekte gediagnoseer word, moet die regulerende owerhede daarvan in kennis gestel word.

Woon en bestuur

In die meeste gevalle is BDV fataal by perde, maar diegene wat dit oorleef, het permanente newe-effekte van hierdie verswakkende toestand, soos verminderde breinfunksie of ander neurologiese gestremdhede wat ambulasie kan bemoeilik. Genadedood word dikwels verkies.
