Effect of Antimicrobials on Salmonella Spp. Strains Isolated from Poultry Processing Plants Rev. Bras. Ciênc. Avic.
Mion,L; Parizotto,L; Calasans,M; Dickel,EL; Pilotto,F; Rodrigues,LB; Nascimento,VP; Santos,LR.
ABSTRACT The routine use of antimicrobials in animal production for the treatment of infections, disease prevention, or as growth promoters is a predisposing factor for the development and dissemination of antimicrobial resistance. In food industries, sanitizers are used for the control of microbial colonization, and their efficacy depends on contact time and on the dilution of the products used. The present study assessed the effect of 12 antimicrobials and four commercial sanitizers on 18 Salmonella spp. strains isolated from poultry processing plants. None of the evaluated antimicrobials was 100% effective against the tested Salmonella spp. strains; however, 94% of the isolates were susceptible to ciprofloxacin, 77% to amoxicillin + clavulanic acid and...

Miniaturized most probable number for the enumeration of Salmonella sp in artificially contaminated chicken meat Rev. Bras. Ciênc. Avic.
Colla,FL; Mion,L; Parizotto,L; Rodrigues,LB; Pilotto,F; Dickel,EL; Nascimento,VP do; Santos,LR dos.
Salmonella is traditionally identified by conventional microbiological tests, but the enumeration of this bacterium is not used on a routine basis. Methods such as the most probable number (MPN), which utilize an array of multiple tubes, are time-consuming and expensive, whereas miniaturized most probable number (mMPN) methods, which use microplates, can be adapted for the enumeration of bacteria, saving up time and materials. The aim of the present paper is to assess two mMPN methods for the enumeration of Salmonella sp in artificially-contaminated chicken meat samples. Microplates containing 24 wells (method A) and 96 wells (method B), both with peptone water as pre-enrichment medium and modified semi-solid Rappaport-Vassiliadis (MSRV) as selective...
