本邦の家庭猫における猫免疫不全ウイルス(FIV)抗体,猫白血病ウイルス(FeLV)抗原および猫コロナウイルス(FCoV)抗体の陽性率を検討した.胸・腹水貯留により猫伝染性腹膜炎(FIP)が疑われた症例でのFIVとFeLVの陽性率はそれぞれ26.3%,36.8%で,健康猫(FIV
9.3%,FeLV 8.1%)に比べ高い値を示した.上部気道炎を呈する症例でのFIVとFeLVの陽性率はそれぞれ35.7%,21.4%で,健康猫に比べ高い値を示した.以上の成績から,FIVやFeLVの感染がFIPや呼吸器感染症の顕性化の一因である可能性が示された.一方,健康猫におけるFCoVの陽性率は47.7%と,FIV,FeLVに比べ高く,FCoVの野外での伝播力の強さがうかがわれた.また,貧血症例が66.7%ときわめて高いFeLV陽性率を示したことから,貧血を伴う症例においてFeLV検査は不可欠な診断手段であることが示された. -------------------- 日獣会誌 55,89〜93(2002)
Serologic Survey of the Feline Immunodeficiency-Virus Antibody, the Feline Leukemia-Virus Antigen, and the Feline Coronavirus Antibody in Domestic Cats*Marupi Lifetech Co., LTD., 103 Fushio-cho, Ikeda 563-0011, Japan SUMMARY Studies were made of the feline immunodeficiency-virus (FIV) antibody, the feline
leukemia-virus (FeLV) antigen, and the feline coronavirus (FCoV) antibody in Japanese domestic cats.
In cases in which pleural and peritoneal exudates led to suspicion of feline infectious peritonitis (FIP),
26.3% of the examined animals were positive for FIV and 36.8% were positive for FeLV. In cases of upper
respiratory diseases, 35.7% were positive for FIV and 21.4% for FeLV. The values were higher than those
for clinically healthy cats: 9.3% positive for FIV and 8.1% positive for FeLV. These findings suggest
that FIV and FeLV infections may contribute to the appearance of FIP and respiratory infections. The
percentage of cats positive for FCoV (47.7%) was much higher than those for FIV and FeLV in healthy cats.
This suggests that FCoV is highly contagious. The extremely high prevalence of FeLV (66.7%) in anemic
cats indicates that FeLV tests are indispensable diagnostic tools in dealing with cats developing anemia.
