“…On the other hand, none of the strains was resistant to chloramphenicol (Table 1), as previously reported by Cardoso et al (2006), Lima et al (2009), Begum et al (2010, and Galdino et al (2013). These authors also did not find any resistance to norfloxacin in Salmonella strains isolated from chicken products.…”

The objectives of this study were to evaluate the antimicrobial resistance and the biofilm-producing ability of Salmonella sp. strains isolated from frozen poultry carcasses. Antimicrobial susceptibility was tested by the disk-diffusion method. Biofilm-producing ability was determined in 96-well polystyrene microplates stained with crystal violet at 1%. Out of the 22 strains tested, all were multiresistant, that is, resistant to more than three antimicrobial classes, and 72.7% were able to form biofilms. The highest resistance rates obtained were against sulfonamides, tetracycline, and quinolones. On the other hand, 100% of the strains were sensitive to chloramphenicol. According to the rate of biofilm formation, 3 (13.6%) and 13 (59.1%) strains were classified as moderate and weak biofilm-producers, respectively, and 27.3% did not form biofilms. Biofilms increase the tolerance of microorganisms to stress, reducing their sensitivity to disinfectants and antimicrobials; favor equipment corrosion; and act as substrates for the adhesion of bacteria with lower biofilm-producing capacity. The results of the present study stress the importance of cleaning procedures in food processing plants and highlight the public health risks related to the emergence of multiresistant strains.

“…Also, the result of Cardoso et al (2006) mentions, besides ciprofloxacin, the susceptibility to gentamicin, norfloxacin and sulfazotrin of strains isolated from chicken carcasses in the state of Rio Grande do Sul is similar to our results. Medeiros et al (2011), researching the resistance of 18 Salmonella serotypes isolated from frozen broiler carcasses in 15 Brazilian cities against antimicrobials, found that strains of S. enteritidis were resistant to all antibiotics tested, at various levels, including antimicrobials used in this study.…”

“…For example, a few studies were found reporting the isolation of salmonella serotypes with high-level resistance in Brazil (Silva and Duarte, 2002;Cardoso et al, 2006;Ribeiro et al, 2007;Souza et al, 2011), Spain (Carramiñana et al, 2004), Lithuania (Ruzauskas et al, 2005), Nigeria (Okolli et al, 2006), United States (Alali et al, 2010) and Greece (Sakaridis et al, 2011). These studies reported that Salmonella from poultry source are resistant to a wide range of antimicrobials and confirmed that poultry are important reservoirs of multidrug-resistant Salmonella.…”

This study was conducted to determine the occurrence and antimicrobial resistance of Salmonella serotypes isolates from feces, feed and broiler litter in poultry broilers in western Paraná between 2006 and 2010. The antigenic characterization and identification of serotypes confirmed 118 samples of Salmonella spp., belonging to 38 different serotypes. The most common serotypes identified were S. enteritidis (16.1%), S. heidelberg (5.9%), S. typhimurium (5.9%), S. hadar (5.0%), S. albany (4.2%), S. enterica (4.2) and S. saintpaul (4.2%). The serotypes of Salmonella spp. isolates were examined for resistance against 13 antibiotics using the disc diffusion method. Thirty-six samples (30.5%) were susceptible to all antimicrobials, and among the 82 resistant strains, there were 25 different resistance patterns. Serotypes' multi-resistant to streptomycin, nalidixic acid and tetracycline (20.7%), nalidixic acid (13.4%) and nalidixic acid and tetracycline (11.0%) were found at higher frequency. The results revealed high prevalence of Salmonella spp. mainly S. enteritidis (16.1%) in aviary environment and percentage of strains' resistant to conventional antibiotics.

“…Resistance to nitrofurantoin (32%), and streptomycin (16%) was low when compared to the 95% found by Cardoso et al (9) in S. Enteritidis, and the 100% found by Ribeiro et al (22) in S. Hadar.…”

The present study was carried out to evaluate the occurrence of Salmonellae in raw broiler parts and to determine the antimicrobial resistance profile of the isolated strains. Twenty-four (39.3%) broiler parts samples were positive for Salmonella and twenty-five Salmonella strains were isolated, since two different serovars were detected in one single positive sample. Salmonella Enteritidis was the most prevalent serovar. Among Salmonella Enteritidis isolates, 95.2% belonged to Phage Type 4 (PT4) (20/21) and 4.8% to PT7 (1/21). Twenty-two (88%) strains of Salmonella were resistant to at least one antimicrobial agent, generating eight different resistance patterns. The S. Typhimurium (n: 1) and S. Hadar (n: 3) isolates presented multiple resistance. Three S. Enteritidis isolates were susceptible to all antimicrobials tested, two were resistant only to tetracycline. The high prevalence of Salmonella in the broiler parts strenghtens the importance of the use of good manufacturing practices (GMP), and HACCP. The results also emphasize the need for the responsible use of antimicrobials in animal production.
