Surveillance of antimicrobial resistance, phenotypic, and genotypic patterns of Salmonella enterica isolated from animal feedstuffs: Annual study

Background and Aim: Salmonellosis is a significant foodborne disease that causes serious illness in the gastrointestinal of humans it public health problem worldwide. This study aimed to determine Salmonella spp. animal feeds, its characteristic, serovar identification, genotyping, drug sensitivity. Materials Methods: from feedstuffs was collected January 1 December 31, 2017, with 657 samples. Serogroup classification performed by using slide agglutination test. Then, samples were analyzed for genotype patterns pulsed-field gel electrophoresis (PFGE) DNA fingerprint antibiotic sensitivity Vitek® 2 techniques. Results: A total 80 (12.17 %) found be positive; commercial feed compounds 60 (75%); soybean meal 10 (12.5%); pork 5 (6.25%); fish three (3.75%) poultry (2.5%). Serogroups B, C, D, E this study; 8 (10%), 39 (48.75%), 13 (16.25%), respectively. 12 (15%) not determined serogrouping. The most common serovars Rissen Mbandaka (8.75%), Livingstone (6.25%), which belong serogroup C. Nine eleven pulsotypes detected when PFGE, showed similarity index between 40.8 100 %. Antimicrobial susceptibility tests compact 11 strains classified into groups: resistance 4, 8, antibiotics, out 20 antibiotics. Conclusion: revealed annual variation Serovar, genotype, phenotype raw materials involved people must aware. Keywords: compounds, spp., serotype.
