ABSTRACT

Objective By studying the acute brucellosis patients' blood culture and the bacteria strains,we tried to confirm the bacteria strains,and to further explore the symptoms and the results of the treatment.Methods Totally 122 acute brucellosis patients were selected,who were in hospital in Heilongjiang Provincial Nongken General Hospital from 2012 to 2013.The patients aged 6-73 years old,whose average age was 36.5(including 83 males and 39 females).All of the subjects were detected in the aspects of blood culture and brucellosis serology,all of whom were treated with aminoglycoside,4-quinolones and cephalosporins.Results All the subjects were Brucella melitensis biovar,of which 104 were Brucella melitensis biovar 3,18 were Brucella melitensis biovar 1.All of them had positive results in rose bengal plate agglutination test (RBPT).In serum tube agglutination test (SAT),the valence of Brucella melitensis biovar 1 and 3 were uniformly distributed,Brucella melitensis biovar 1 was distributed mainly in 1∶800 valence zone,Brucella melitensis biovar 3 was distributed mainly in 1∶400 valence zone.The distribution trends in Coombs test and complement fixation test (CFT) were similar.In Coombs they were distributed mainly in 1∶800 valence zone,and in CFT were distributed mainly in 1∶40 zone.All of the subjects had typical symptoms of brucellosis,and had various kinds of complications (spondylitis,toxipathic hepatitis,et al).Totally 112 of them were recovered,and 10 were improved.Conclusion The human brucellosis in Heilongjiang Province is caused by Brucella melitensis biovar 1 and 3,with severe symptoms and various kinds of complications,earlier diagnose and treatment will have a better effect.
