Abstract:
Objective To study the bacteriological change in buccal mucosa of sailors during long-term voyage and provide basis for the prevention and treatment of buccal diseases .Methods Bacterial cultivation ,isolation of 164 buccal mucosa specimens were used and analyzed by both handwork and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) identification .Results 18 species and 64 strains of pathogenic bacteria were isolated from the whole samples .The num-ber of pathogenic bacteria increased while the number of dwelling bacteria decreased significantly later in the voyage .Comparing with the medical group ,the number of pathogenic bacteria detected in mechanical and electrical group was significantly high (P<0 .05) ,during and after the long-term voyage .As for dwelling bacteria ,no significant difference was observed in between the two groups(P>0 .05) .Conclusion Sailors to fatigue during long-term voyage indicates by decline of immunological function and buccal dysbacteriosis ,which easily lead to buccal and other system diseases .
