“…The authors mention that probably the large number of serotypes recognized results from the mixture of a large number of inputs of same rating but from different sources; this probably being the same reason for the difference between the serotypes isolated from this study. In relation to feces, the data of the present study disagree with Oliveira et al (2006), who analyzing samples of feces and carcasses of broilers in the state of Ceará, Brazil observed contamination by Salmonella spp. only in the carcasses.…”

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.

“…This is supported by previous data from around the world (Uyttendaele et al, 1998;Dominguez et al, 2002;Goncagü l et al, 2005;Oliveira et al, 2006). The presence of Salmonella Enteritidis in poultry meat is a significant contamination risk, as many authors report that this serovar represents the main source of foodborne diseases (Humphrey and Jørgensen, 2006;Oliveira et al, 2006).…”

“…According to the Centers for Disease Control and Prevention (CDC) in United States, there are 1.34 million of cases of disease, 16.430 hospitalizations, and 582 deaths each year. The total annual cost resulting from foodborne Salmonella infections is estimated to be approximately $3.5 billion (Oliveira et al, 2006). According to Humphrey and Jørgensen (2006), an estimated 100,000 cases of Salmonella infection in the United Kingdom every year are indicative of much of Western Europe.…”

This study was conducted in order to estimate the proportion of raw meat and processed meat products contaminated by Salmonella in the region of Algiers, Algeria, to identify serovars and to determine the antimicrobial resistance patterns of isolates. Out of the total 314 samples (144 of raw red meat and meat products, 128 of raw poultry meat and poultry products, and 42 of processed meat products) collected from various retail outlets, 61 (19.43%) were tested positive for Salmonella. The most significant occurrences were recorded for the categories of red meat (23.61%, n=34) and poultry (17.97%, n=23). Among the 64 isolates recovered, 21 different serovars were identified and two strains were nontypable. The most prevalent serovars were Salmonella Anatum (14.6%, n=9), Salmonella Altona (12.50%, n=8), Salmonella Corvallis (7.81%, n=5), Salmonella Enteritidis (7.81%, n=5), and Salmonella Typhimurium (7.81%, n=5). Sixty-two Salmonella isolates were tested for their susceptibility to 32 selected antimicrobial agents. Fifty-six (90.32%) isolates were resistant to at least one antimicrobial, of which 20 (32.26%) showed multidrug resistance. Resistance to sulphonamides (87.10%, n=54) was the most common. Resistance rates were lower to nalidixic acid (16.13%, n=10), streptomycin (16.13%, n=10), and tetracycline (12.90%, n=8), while resistance to pefloxacin was estimated at 4.84% (n=3). Fourteen different resistance patterns were observed. The "ACSSuT" pentaresistance pattern was observed in three of the Salmonella Typhimurium strains. The obtained results show that these foodstuffs are a potential source of antimicrobial-resistant Salmonella for human infections.

“…The data from the present study indicated that all isolated Salmonella strains exhibited absolute resistance (100%) against amoxicillin/clavulanic acid, indicating the limited therapeutic value of this antibiotic. Of the most common antimicrobial resistance in Salmonella, beta-lactam resistance was cited previously in Pakistan and Brazil [29,30] and can therefore be considered a worldwide problem. This resistance may be attributed to indiscriminate use of antibiotics at recommended doses or at subtherapeutic doses as feed additives to promote growth, and as chemotherapeutic agents to control epizootic diseases on farms.…”

Introduction: Salmonella serovars are one of the primary foodborne pathogens. Poultry consumption is responsible for the majority of disease cases worldwide. The prevalence of virulence determinants among Salmonella serovars appears to be lacking in Egypt. Therefore, this study investigated the occurrence, antibiotic resistance patterns, and virulence gene profiling of Salmonella serovars in broilers. Methodology: Three hundred samples from broiler chickens were examined for the presence of Salmonella by standard microbiological techniques. All Salmonella isolates were tested for their sensitivity against ten antibiotics and subjected to virulence genotyping by polymerase chain reaction (PCR). Results: The overall isolation percentage of Salmonella was 17%. Seven different serovars were found, with the main one being Salmonella Typhimurium (52.94%). Salmonella isolates were sensitive to most of the tested antibiotics, but they exhibited absolute resistance against amoxicillin/clavulanic acid. Nine Salmonella strains (52.94%) were resistant to at least three antibiotics. Further PCR investigations into 17 Salmonella strains revealed different distribution patterns of eight virulence determinants among the isolates. The invA gene was the most prevalent one (100%), followed by hilA (88.24%), stn (58.82%), and fliC genes (52.94%), while each of sopB and pefA genes had a similar prevalence (41.18%), and sefC and spvC genes had the lowest prevalence (11.76 and 5.88%, respectively). PCR genotyping allowed grouping of Salmonella strains into ten genetic profiles. Conclusions: These results will help in understanding the spread of virulence genotypes and antibiotic resistance among Salmonella serovars in broilers.
