Following the upsurge of Q fever epidemic in the village Jedl'ové Kostol'any, Nitra district, Slovakia, in April 1993, the possibility of the penetration of coxiellae into free nature was investigated for the next two years. Micromammals and their ectoparasites, primarily ticks, were employed as indicators of the presence of the infection in nature. The infestation of mammals and their ectoparasites was followed in J. Kostol'any on the farm where the goats were housed as well as in its close proximity. The infestation of ticks with coxiellae was further followed in four localities of the Rimavská Sobota district, where the goats after the eradication of Q fever outbreak in J. Kostol'any were transferred for breeding. The presence of coxiellae was not proved in these investigated localities. It is suggested that the pathogenicity of imported C. burnetii strains through Bulgarian goats was decreased under local environmental conditions including the ability to circulate freely in nature or these strains found inconvenient conditions for maintaining their viability.
1993年4月斯洛伐克尼特拉地区耶德尔科韦科斯托拉尼村Q热疫情爆发后，在接下来的两年里对柯克斯体渗入自然环境的可能性进行了调查。小型哺乳动物及其体表寄生虫，主要是蜱虫，被用作自然环境中感染存在的指标。在饲养山羊的农场及其附近地区，对科斯托拉尼村的哺乳动物及其体表寄生虫的感染情况进行了跟踪。在里马夫斯卡索博塔地区的四个地方，进一步跟踪了蜱虫感染柯克斯体的情况，这些地方是在科斯托拉尼村Q热疫情根除后，从该村转移来用于繁殖的山羊所在之处。在这些调查地点未证实存在柯克斯体。有人认为，通过保加利亚山羊引入的伯纳特柯克斯体菌株在当地环境条件下致病性降低，包括在自然环境中自由传播的能力，或者这些菌株发现维持其生存能力的条件不利。
