Abstract
BACKGROUND Salmonella is one of the most important enteric pathogenic bacteria that threatened poultry health. AIMS This study aimed to investigate the prevalence and antimicrobial resistance of Salmonella isolates in goose farms. METHODS A total of 244 cloacal swabs were collected from goose farms to detect Salmonella in Northeast China. Antimicrobial susceptibility, and resistance gene distribution of Salmonella isolates were investigated. RESULTS Twenty-one Salmonella isolates were identified. Overall prevalence of Salmonella in the present study was 8.6%. Among the Salmonella isolates, the highest resistance frequencies belonged to amoxicillin (AMX) (85.7%), tetracycline (TET) and trimethoprim/sulfamethoxazole (SXT) (81%), followed by chloramphenicol (CHL) (76.2%), florfenicol (FLO) (71.4%), kanamycin (KAN) (47.6%), and gentamycin (GEN) (38.1%). Meanwhile, only 4.8% of the isolates were resistant to ciprofloxacin (CIP) and cefotaxime (CTX). None of the isolates was resistant to cefoperazone (CFP) and colistin B (CLB). Twenty isolates (95%) were simultaneously resistant to at least two antimicrobials. Ten resistance genes were detected among which the bla TEM-1, cmlA, aac(6')-Ib-cr, sul1, sul2, sul3, and mcr-1.1 were the most prevalent, and presented in all 21 isolates followed by tetB (20/21), qnrB (19/21), and floR (15/21). CONCLUSION Results indicated that Salmonella isolates from goose farms in Northeast China exhibited multi-drug resistance (MDR), harboring multiple antimicrobial resistance genes. Our results will be useful to design prevention and therapeutic strategies against Salmonella infection in goose farms.

Abstract
OBJECTIVES To evaluate the application of 43-plex SNP typing system in forensic science. METHODS The typing of 43 SNP loci in 123 unrelated Han individuals from East China was detected by MALDI-TOF-MS. The application value of 43-plex SNP typing system was assessed according to the forensic parameters of population genetics. RESULTS All the 43 SNP loci of 123 individuals showed no significant departure from Hardy-Weinberg equilibrium （P>0.05）. Excepted rs1355366, rs2270529, rs10776839 and rs938283, there were 39 SNP loci had minor allele frequencies （MAF）, which were greater than 0.25. Among the 25 loci MAFs, 24 ranged from 0.4 to 0.5, while 3 were close to 0.4. The DP, CDP, PIC, Ho, PEtrio and PEduo of the 43 SNP loci were 0.290 1-0.654 4, 1-9.8×10⁻¹¹, 0.170 8-0.500 0, 0.155 7-0.593 5, 0.085 4-0.250 0 and 0.014 6-0.125 0, respectively. The CPEtrio and CPEduo were 0.999 986 and 0.992 436 1, respectively. CONCLUSIONS The 43-plex SNP typing system in present study shows a high polymorphism, which can be an effective supplement and verification for traditional STR genetic markers. It also can be used with other commercial kits for the forensic paternity testing and individual identification.

Abstract
In this study, we isolated microsatellite DNA from the Huoyan goose genome with magnetic beads. As a result, 150 positive clones were identified, and 148 microsatellites were found. Among the 148 microsatellites, 69.6% were perfect, 17.6% were imperfect, and the rest were compound type (12.8%). Twenty microsatellite primers were used to screen 90 individuals from 3 Huoyan goose populations. Eight loci were polymorphic with a low number of alleles (2 to 4). The observed and expected heterozygosities ranged from 0.3556 to 1 and from 0.2923 to 0.6868, respectively. All the 8 polymorphic loci were in Hardy-Weinberg equilibrium. These molecular markers will be useful for future studies on population genetic structure and conservation genetics in Huoyan geese.
