During the summer and autumn periods of 1990-1992 a periodic massive incidence, infestation as well as parasitization of humans with flea Ctenocephalides felis were recorded in the basements of flat blocks in the central area of Kosice. The urban population of domestic cats served as a source of the infestation. The dark field examination of fleas for the presence of borrelias revealed negative results.
1990 - 1992年夏秋期间，在科希策市中心区域公寓楼的地下室记录到了猫栉首蚤对人类的周期性大规模侵袭、侵扰以及寄生情况。城市家养猫群体是侵扰的来源。对跳蚤进行暗视野检查以检测疏螺旋体，结果呈阴性。
