比较了牛莫拉氏菌分离株的非纤毛型和纤毛型的质粒图谱。牛分枝杆菌IBH64分离株的有菌毛型比无菌毛型少1个质粒。IBH64的有毛和无毛细胞含有分子大小为45、32.8、4.9和4.6 kb的质粒。Ava I和Nde I的单和双限制性内切酶消化表明，IBH64的非纤毛形式携带的额外质粒的大小约为43.6 kb。牛支原体分离株纽波特和GRS在有菌毛或无菌毛形式中含有相同数量的质粒。
Plasmid profiles were compared between nonpiliated and piliated forms of Moraxella bovis isolates. The piliated form of M bovis isolate IBH64 contained 1 fewer plasmid than did the nonpiliated form. Piliated and nonpiliated cells of IBH64 contained plasmids having molecular size of 45, 32.8, 4.9, and 4.6 kilobases (kb). Single- and double-restriction endonuclease digestion by Ava I and Nde I indicated that the size of the additional plasmid carried by the nonpiliated form of IBH64 was approximately 43.6 kb. The M bovis isolates, Newport and GRS, contained the same number of plasmids in either their piliated or nonpiliated form.
