Differences of Nuc-mecA Gene Carriage in the Noses among Different Altitudes in High Humidity District / 现代检验医学杂志

ABSTRACT

Objective To investigate the carriage of nuc-mecA gene among different altitudes in high humidity district,provid-ed guiding data for prevention of staphylococcus aureus and drug-resistant bacteria,standardizing the usage for antibiotics. Methods The nose swabs were collected in different altitudes:1 000 m,1 200 m and 1 400 m,nuc-mecAgene was confirmed by multi-channel real-time PCR.Results The carrier of nuc gene in the noses were 4.878%,2.899% and 7.143%,in 1 000 m,1 200 m and 1 400 m respectively,and there were no statistical significant among the altitudes (P>0.05).The carrier of mecA gene were 14.634%,31.884% and 41.837% in the 1 000 m,1 200 m and 1 400 m respectively,the difference showed statistical significe (P0.05).Conclusion The carrier of mecA gene in noses was increased with the increasing of the altitude. The residents who living at higher altitude should keep the colonization sites of pathogens clean,and needed timely medical when got sick,shouldn’t abuse the antibiotics without authorization.Medical staff should rational use of antibiotic drugs,a-voided overusing of antibiotics and overtreatment.
