Abstract
鼠傷寒沙門氏菌在其菌體的表面擁有第一型線毛的構造,帶有吸附素可與具有甘露糖受體的宿主專一結合,與表現第一型線毛相關的fim基因群包含九個開放讀碼區和一個tRNA基因。過去的研究發現,鼠傷寒沙門氏菌經過一連串的繼代培養在靜置的液態培養基後,可以篩選出大量表現第一型線毛的細菌,而在固態培養基上的繼代培養則會抑制細菌表現第一型線毛。本研究一方面偵測在靜置液態培養基中或固態培養上細菌的fim相關基因mRNA的表現量,另一方面則是想找出在這兩種不同的培養條件下有表現不同的基因,進而研究此基因與第一型線毛表現的相關性。反轉錄聚合酶鏈鎖反應顯示鼠傷寒沙門氏菌的fimA、fimI、fimD、fimZ和fimW基因在固態培養基不表現但會表現在液態培養基中生長的細菌。fimC、fimF、fimY在靜置的液態培養基中則是有比在固態培養基中有較多的mRNA表現。利用GeneFishingTM聚合酶鏈鎖反應試劑組選殖出在靜置液態培養與固態培養基表現不同的基因,結果發現在靜置的液態培養下有較多ompC, gph, STM1128, modE, upp, dut, cheY的mRNA表現,相反的,在固態培養基則有較多ytfK, yfgB, uup, ycgB, ndk, aroC的mRNA表現。以上基因與fim基因之間的關聯性,將會持續研究並闡明其控制鼠傷寒沙門氏菌第一型線毛表現的機制。
