Two of four calves inoculated with Leptospira interrogans serovar balcanica developed low microscopic agglutinating (MA) titres to serovar hardjo. A third calf had an MA titre of 1:1024 by day 19 post-inoculation (PI). Transient leptospiruria was recorded in one calf on days 12 and 13 PI. An in-contact calf did not seroconvert. None of the calves had fever or other clinical signs of disease. Four ewes inoculated with balcanica developed MA titres to hardjo by day 13 PI, and a transient leptospiruria between days 14 and 25 PI. None of the ewes showed any evidence of clinical disease and three of them delivered healthy lambs 22 to 64 days PI. One ewe had mild lesions of focal interstitial nephritis.
接种问号钩端螺旋体巴尔干尼亚血清型的四只小牛中，有两只对哈德乔血清型产生了低水平的显微镜凝集（MA）效价。第三只小牛在接种后第19天（PI）的MA效价为1:1024。在接种后第12天和第13天，有一只小牛出现了短暂的钩端螺旋体尿。一只接触感染的小牛没有发生血清转化。所有小牛均未出现发热或其他疾病临床症状。接种巴尔干尼亚血清型的四只母羊在接种后第13天对哈德乔血清型产生了MA效价，并在接种后第14天至25天出现了短暂的钩端螺旋体尿。所有母羊均未表现出任何临床疾病迹象，其中三只在接种后22至64天产下了健康的羔羊。一只母羊有局灶性间质性肾炎的轻度病变。
