The incidence of resistance to various antibiotics as well as the capacity to elicit aggregation response to sex pheromones have been investigated in strains of Enterococcus faecalis isolated from clinical and municipal waste waters (MWW). While clinical isolates showed a high incidence of antibiotic resistance (87%) and sex pheromone response (33%), these traits appeared with a much lower frequency in MWW isolates (12% and 4% respectively). The simultaneous incidence of both traits was of 52% and 0% for clinical and MWW isolates, respectively. The capacity to elicit a positive pheromone response as well as antibiotic resistance traits seemed to be strongly correlated with the presence of gelatinase activity among clinical isolates. Among MWW isolates, only sex pheromone response seemed to correlate with the presence of gelatinase activity.
已对从临床和城市污水(MWW)中分离出的粪肠球菌菌株进行了针对各种抗生素的耐药性发生率以及对性信息素引发聚集反应的能力的研究。虽然临床分离株显示出较高的抗生素耐药性发生率(87%)和性信息素反应发生率(33%),但这些特性在MWW分离株中出现的频率要低得多(分别为12%和4%)。这两种特性的同时发生率在临床分离株和MWW分离株中分别为52%和0%。在临床分离株中,引发阳性信息素反应的能力以及抗生素耐药特性似乎与明胶酶活性的存在密切相关。在MWW分离株中,只有性信息素反应似乎与明胶酶活性的存在相关。
