摘要

Non-typhoid Salmonella (NTS) are cosmopolitan bacterial zoonotic agents. The present study wasundertaken to determine the occurrence of NTS in human and camels and test the survival of Salmonellaenteritidis in abattoir effluents using volume germ carriers technique. A total of 50 human stool samplesincluding 30 diarrheic and 20 non-diarrheic were collected. Moreover, 108 camel samples were collected from36 slaughtered camels including feces, mesenteric lymph nodes and liver, 36 each. All samples were culturedby the standard methods for NTS and serotyped. Four (8%) Salmonella isolates were obtained from humanstool and 6(5.6%) from camel samples. The positive camel samples included 5 feces and one mesentric lymphnodes with the frequencies of 13.9% and 2.8%, respectively. Nevertheless, the liver samples were Salmonellafree (N=36). Three replicates of volume germ carriers were inoculated with Salmonella enteritidis at 7 logCFU/ml in final mix. The contents of germ carriers were examined on days 7, 14, 21 and 28 for the detection ofSalmonella enteritidis by the most probable number technique. The mean counts of the 3 replicates were 5,3 and 0.7 log CFU/ml on days 7, 14 and 21, respectively. The mean number of Salmonella was decreased by2.2 log week 1. On the day 28, all the 3 replicates count were found to be under detection limit (< 0 logCFU/ml). The results indicate that aerobic storage of abattoir effluents could minimize the risk of salmonellosisin the environment under the research condition. It can be concluded that camels could be a potential reservoirfor NTS to humans and animals.
