Igama elithi "Spirochaetaceae" igama lesayensi elisetshenziswa kubhayoloji ukuze libhekisele emndenini wamagciwane okuthiwa i-Spirochaetes. I-Spirochaetes iyi-phylum ye-Gram-negative, amagciwane amise okwe-spiral anamaseli ahlukile amise okwe-spiral futhi akwazi ukwenza i-axial filament-based motility, ewavumela ukuthi ahambe ngendlela efana ne-corkscrew. Umndeni we-Spirochaetaceae ungomunye wemindeni engaphakathi kwe-phylum Spirochaetes, futhi uhlanganisa izinhlobo ezimbalwa zamagciwane, njenge-Treponema, i-Borrelia, ne-Leptospira. Lawa mabhaktheriya aziwa njenge-parasitic, pathogenic, noma symbiotic, futhi ezinye izinhlobo zomndeni we-Spirochaetaceae zinesibopho sokubangela izifo kubantu nasezilwaneni, okuhlanganisa ugcunsula, isifo se-Lyme, ne-leptospirosis.
