초록

일주령 20 kg 한우 송아지가 급성으로 침울, 보행실조, 횡와위 그리고 진전을 보여 전북대학교 전북동물의료센터로 내원하였다. 시력소실과 각막부종도 관찰되었다. 안구진탕과 사시 그리고 후궁반장까지 보이는 등 점점 증상은 악화되었다. 혈액검사 결과 뚜렷한 백혈구 증가증 및 저알부민혈증과 BUN증가를 관찰하였다. 단순방사선검사에서는 특이소견이 관찰되지 않았다. 자기공명영상 검사 결과 측뇌실, 제3뇌실 그리고 제4뇌실의 확장을 관찰하였으며 대뇌 좌측 측두엽의 피질과 백질 부위에 국소적으로 T1강조영상에서 저신호로 T2강조영상에서 고신호로 그리고 조영T1강 조영상에서 미약하지만 조영증강효과가 관찰되었다. 뇌척수액 검사결과 대장균 감염이 확인되었다. 환자는 치료에 반응하지 않고 입원 3일 후 폐사하였다. 조직병리학적 검사에서 대장균 감염에 의한 심각한 다발성 섬유-화농성 뇌막염으로 확진되었다.

A 1-week-old, male Korean native calf with acute clinical signs of depression, mild diarrhea, ataxia, recumbency and tremor was referred to Chonbuk Veterinary Medical Center of Chonbuk National University. Vision loss and cornea edema were also observed on physical examination. The patient had been deteriorated with nystagumus, strabisumus and opisthtonus. Blood cell count test and blood biochemistry test revealed remarkable leukocytosis, and hypoalbuminemia and increased blood urea nitrogen. No remarkable findings were observed on radiography. On magnetic resonance imaging study, there were enlarge lateral, third, and forth ventricles. The cortical grey and subcortical white matter of left temporal lobe showed hypointense on T1-weighted images and hyperintense on T2-weighted images, and slightly enhanced on contrast-enhanced T1-weighted images. Escherichia coli strain was identified from cerebrospinal fluid sample. Palliative treatment was attempted but the neonatal calve was expired three days after admission. Severe multifocal fibrino-suppurative meningitis with Escherichia coli infection was confirmed histopathologically.
