Abstract: Salmonella enterica is frequently associated with outbreaks of human salmonellosis, and products of avian origin, such as eggs and chicken meat, are the main vehicles of its transmission. The present study describes the occurrence of different serovars of Salmonella enterica and phagotypes of S. enterica serovar Enteritidis in eggs destined for human consumption. Four thousand eggs obtained from commercial egg laying farms and one thousand discarded hatching eggs from broiler farms, which were acquired at farm… Show more

“…Regarding the frequency of isolation of Salmonella spp. from eggshells in the current study, 2.0% of the pooled eggshells (4 of 196), is slightly higher than the frequency of 1.05% reported by Chemaly et al () for layer farms in France, the 0.07 to 0.4% in Canada (Poppe, Duncan, & Mazzocco, ), and the failure (0.0%) to isolate the pathogen from eggshells by others (Adesiyun et al, ; Kemal, Sibhat, Menkir, & Beyene, ; Kottwitz et al, ). Our finding in the current study, however, is low compared with the isolation rate of 3.5% for Salmonella spp.…”

“…Nitrofurantoin resistance frequencies vary widely, some exceeding 50% and others below 10%. The same occurs with tetracycline; resistance frequencies range between 10% and 30% [35,[37][38][39][40][41][42][43][44][45].…”

“…Resistance frequencies to folate inhibitors are generally high but variable, similar to the strains isolated from poultry [35,37,38,40,42,52,80,81,83,84]. However, the frequency of aminoglycoside resistance frequencies is generally higher in Salmonella strains isolated from pigs (Tables 1 and 2) [38,41,52,75,81,84,85].…”

Bolded and underlined isolates in parentheses: serotyped as Salmonella enterica subspecies enterica serovar Enteritidis/ derived food and avian isolates in this study could be mainly related to the production system used; differences in slaughtering and cooling processes; variations in market types and storage conditions; differences in sampling period, year, and region; sampling methods; sample type; and isolation and identification method used (13,20,26). SE-rPCR results of the 56 total Salmonella isolates indicated that 33 (59%) and 23 (41%) of the isolates were positive and negative, respectively.…”
