這可以是 貓腸道冠狀病毒(FCoV) 可以是 貓傳染性腹膜炎病毒(FIPV) 。
前者 廣泛存在 於貓的腸道中且有 強傳染性 ,後者具有 極強的致死性 [1] 。
傳染性有多強呢,如果一群貓中有 一只為陽性 ,那麽這群貓中的 9成已經被感染了 。
而 病毒性腸炎與傳染性腹膜炎呈現高度關聯性 ... [2] [3]
遺憾的是, FCoV與FIPV之間沒有明顯的界限。
2012年,貓傳腹研究泰鬥Neils C Pedersen教授研究發現 FIPV其實是FCoV的變種 。 [4]
變異之前, FCoV 只能引起一些 胃腸炎癥 ,是一種 「自限性疾病(Self-limited Disease)」 ,病程可以自行停止,腸道上的損傷也能自愈 。
但一旦貓咪抵抗力降低,FCoV就會大量復制,像新冠病毒一樣,復制多了,難免出現變異——於是就有了FIPV [5] [6] [7] [8] 。
而 FIPV 引發的疾病,就是令諸多獸醫頭禿、鏟屎官聞風喪膽的 傳染性腹膜炎(FIP) 。
也正因此, FIP多發於抵抗力低的幼貓(<1歲)和老貓(>11
