A correlation between the genospecies (DNA-DNA hybridization group) and the type of siderophore produced by 118 isolates of the genus Aeromonas was established. Organisms in hybridization groups 1 through 5 (including 5A, 5B, and 5AB) and group 12 predominantly produced the siderophore amonabactin, while an enterobactinlike siderophore was prevalent in groups 8/10 and 9. The siderophore produced by strains in group 6 may be an as-yet-unidentified nonphenolate, nonhydroxamate compound, and group 7 isolates synthesized no siderophores. Determination of the indigeneous siderophore (or the absence of one) produced by an isolate of the genus Aeromonas may assist in identification of the organism's genetic species and may suggest the presence of certain virulence properties.
已确定气单胞菌属118个分离株的基因种(DNA-DNA杂交组)与所产生的铁载体类型之间的相关性。杂交组1至5(包括5A、5B和5AB)以及组12中的菌株主要产生铁载体氨纳巴菌素,而肠杆菌素样铁载体在8/10组和9组中普遍存在。6组菌株产生的铁载体可能是一种尚未鉴定的非酚盐、非异羟肟酸化合物,7组分离株不合成铁载体。确定气单胞菌属分离株产生的本土铁载体(或不存在铁载体)可能有助于鉴定该生物体的基因种,并可能提示某些毒力特性的存在。
