RESUMO
Objective To analyze the epidemiological characteristics of brucellosis for improving its clinical and laboratory diag‐nostic ability .Methods The clinical and laboratorial data of the patients with brucellosis in our hospital from January 2013 to Sep‐tember 2015 were retrospectively analyzed .Results In 39 cases of brucellosis ,the majority had the sheep‐contacting history and the clinical manifestations were mainly fever (100 .0% ) ,bone and joint pain(64 .1% ) ,hidrosis(51 .3% ) ,weak(33 .3% ) ,lymph node en‐largement(23 .1% ) and hepatosplenomegaly(12 .8% ) .The laboratory detections showed the abnormal liver function ,rapid erythro‐cyte sedimentation rate(ESR) ,hypersensitive C ‐ reactive protein(hs‐CRP)increase ,lymphocytes percentage increase ,positive for brucellosis antibody agglutination test ,positive blood culture or medulloculture ,which was identified as Brucella melitensis by bacte‐riology .Conclusion The clinical manifestations of brucellosis are diversity and is easy to be misdiagnosed .The sporadic cases in northern Jiangsu area are increased year by year .The epidemiological clue should be paid attention to and the recognition on brucel‐losis should be strengthened .The patients with fever of undetermined origin should be conducted the blood culture and brucellosis antibody agglutination test as early as possible .
