目前，该属被定义为一个单一的种，即白色贝吉亚托菌（Berggiatoa alba）（Strohl，1989）。然而，这个种命名通常用于任何无色、丝状、滑行的细菌，其沉积元素硫的内部球，但在共同的鞘内不形成毛状体束。在天然材料中已经观察到具有各种丝状体宽度的生物，范围从1-120 μ m，并且假定其属于该属（Jorgensen，1977; Klas，1937;纳尔逊et al.，1989年b），但一个单一的系统发育亲和力组是没有办法证明。贝贾托菌具有重要的历史意义，因为Winogradsky（1887）最早的实验，最终导致了细菌化学自养概念的发展，是用这种生物的自然富集进行的（参见Brock和Schlegel，1989）。
The genus Beggiatoa is currently represented by a single defined species Beggiatoa alba (Strohl, 1989). However, this species designation is commonly used for any colorless, filamentous, gliding bacterium that deposits internal globules of elemental sulfur but does not form bundles of trichomes within a common sheath. Organisms with a variety of filament widths, ranging from 1-120~ m, have been observed in native material and are assumed to belong to this genus (Jorgensen, 1977; Klas, 1937; Nelson et al., 1989b), but a single phylogenetic affinity group is by no means proven. Beggiatoa is of historical importance because Winogradsky's (1887) earliest experiments, which ultimately led to development of the concept of bacterial chemoautotrophy, were performed with natural enrichments of this organism (see Brock and Schlegel, 1989).
