Objective:To study the distribution of species type, biotype and genotype of human Brucella isolated and identified in Nanjing. Methods:A total of 89 strains of human Brucella were collected from microbiology laboratories of three sentinel hospitals in Nanjing from 2017 to 2022. The species type was identified using biological methods and Brucella nucleic acid detection (BCSP31-PCR and AMOS-PCR). Further biotyping of Brucella melitensis isolates was conducted by serological results of A and M factors. Meanwhile, genotype analysis was performed using multiple-locus variable number tandem repeat analysis (MLVA), multilocus sequence typing (MLST) and single nucleotide polymorphism (SNP). Results:From 2017 to 2022, 89 strains of Brucella isolated and identified in Nanjing were all Brucella melitensis. Among them, Brucella melitensis biotype 3 accounted for 82.02% (73/89), and biotype 1 accounted for 17.98% (16/89). MLVA typing showed that 89 strains of Brucella melitensis belong to the "Eastern Mediterranean" cluster and could be divided into 50 MLVA genotypes; among which panel 1 had 3 genotypes, namely Type 42 (84.27%, 75/89), Type 63 (8.99%, 8/89) and Type 43 (6.74%, 6/89). The results of MLST-9 and MLST-21 were both ST8, and the core genome multilocus sequence typing (cgMLST) classified 89 strains into 11 genotypes. SNP analysis revealed a total of 4 013 SNP loci, with SNPs ranging from 0 to 409 across different strains, involving 59 SNP genotypes. Conclusions:The human Brucella strains isolated and identified in Nanjing are all Brucella melitensis, mainly biotype 3. The MLVA cluster is the "Eastern Mediterranean" cluster. The traditional MLST-9 and MLST-21 typing results are all ST8 type, while cgMLST divides all the strains into 11 genotypes with higher resolution.

Objective To investigate the cause and related risk factors of an outbreak caused by Brucellosis. Methods Epidemiological investigation and laboratory test were carried out among occupationally invloved population including sheep slaughters and sellers in the village. Results 18 people were serology positive among the 129 occupationally involved persons under survey. Seven of them were confirmed cases,11 were latent infection,to make the overall attack rate as 14%. 90%of the sheep were from high-risk areas of Brucella. Among the occupationally involved persons,89%of them never wore face masks,84%never wear overalls and 70%never wear gloves. Factors as:work but wearing no gloves(RR=7.4,95%CI:1.1-53.0),with hand wound(RR=3.4,95%CI:1.1-11.0) could increase the risk of Brucella infection. Conclusion The cause of this outbreak was due to the plentiful influx of unchecked sheep from the northern part of China and the employees in the process of sheep slaughtering or trading were lack of effective prevention programs.

Objective:To identify human infection with Brucella suis, analyze its biological and molecular characteristics, and to provide basis for prevention and control of brucellosis. Methods:Brucella suis strains were isolated from the body of the first case of human Brucella suis infection in Jiangsu Province. Serum agglutination test was used for serotyping. The specific gene bcsp-31 of Brucella was detected by PCR. AMOS-PCR was used to identify IS-711. The species and biotypes were identified by multiplex PCR. The wboA gene products were sequenced and phylogenetic tree was constructed. Multilocus sequence analysis (MLSA) was used for molecular typing, and cluster analysis was performed with reference strains. Results:The strain was confirmed to be Brucella suis biotype 3 by serum agglutination test and PCR. After sequencing the wboA gene, cluster analysis of the reference sequence showed that the wboA gene was closest to the biotype 3 strain Brucella suis str. 686 (CP007719). MLSA was typed into ST17(1-6-4-1-5-3-5-2-4). Conclusions:Brucella suis biotype 3 is reported in Jiangsu Province for the first time. The MLSA type is ST17. In the future, the prevention and control of human brucellosis should be carried out. We should actively cooperate with the animal husbandry and veterinary department to increase the quarantine, immunization and other control measures.
