A Case of Haemophilus Parainfluenzae Endocarditis Osamu KURIMURA, Yoshiharu ITO, Hiroshi ICHIMURA & Ikuo TAMURA Institute of Clinical Research, Kure National Hospital HideyukiDOI Clinical Laboratory, Kure National Hospital We reported a case of Haemophilus parainfluenzae endocarditis. A 45-year old male patient, who suffered from fever elevation and was administered some cephems orally or intravenously with no clinical efficacy, visited our hospital. He admitted on 25th March 1986, after a week from the onset of the disease. On admission his body temperature was 40.2 Ž and a grade of Levine II systolic murmur was audible at the mitral ostium, but no sign of the heart failure was recognized. H. parainfluenzae was isolated twicefromfour serial blood cultures.after the bacteriological examinations daily doses of 6.0 g of ampicillin (ABPC) with 600 mg of ofloxacin (OFLX), of 4.0 g of cefotaxime (CTX) and of 6.0 g of THR-221 were administered successively. However, the clinical effects were insufficient, so that the antimicrobial agents were changed on the 27th hospital day again up to daily doses of 9.0 g of ABPC and 600 mg of OFLX for 42 days, and then daily dosis of 2.0 g of amoxillin was prescribed in place of ABPC. The therapy was over on the 87th hospital day discharged on the 102 nd hospital day., resulting in good clinical course. Fainally, he MICs of CTX, THR-221, ABPC and OFLX against the isolated strain were 0.0125ƒÊg/ml, 0.0125
