Abstract：
BACKGROUND: Salmonellosis is one of the most common food-borne diseases in industrialised and developing countries. In recent year, an increase in antimicrobial resistance among different Salmonella serotypes has been observed.
OBJECTIVE: A cross-sectional study was conducted to assess the prevalence and antimicrobial susceptibility of Salmonella isolated from local chicken eggs in four selected towns in Ethiopia.
METHODS: A total of 115 eggs were examined to detect Salmonella by using standard microbiological methods. The susceptibilities of the isolates to nine antimicrobials were tested by the Kirby-Bauer disk diffusion method.
RESULTS: The study revealed that of the 115 eggs examined, 22 (19.1%) were positive for Salmonella of which 14 (12.2%) and 8 (7%) of the isolates were from shells and contents, respectively. The occurrence of Salmonella in egg shells and content and between different altitudes did not differ significantly (p > 0.05). Most isolates were resistant to more than three antimicrobials with a high resistance to kanamycin, ampicillin, nalidixic acid, cotrimoxazole, oxytetracycline and chloramphenicol.
CONCLUSIONS: The results indicate the potential importance of local chicken eggs as source of multiple antimicrobial-resistant salmonellae and the need for proper cooking before consumption. Further studies are required to describe the epidemiology of Salmonella in various agroclimatic zones of Ethiopia.

摘要：
背景：沙门氏菌病是工业化国家和发展中国家最常见的食源性疾病之一。最近一年,已观察到不同沙门氏菌血清型之间的抗菌素耐药性增加。
目的：进行了一项横断面研究，以评估埃塞俄比亚四个选定城镇从当地鸡蛋中分离出的沙门氏菌的患病率和抗菌药物敏感性。
方法：使用标准微生物学方法对总共115个鸡蛋进行了检测，以检测沙门氏菌。通过Kirby-Bauer圆盘扩散法测试了分离株对9种抗菌剂的敏感性。
结果：研究表明，在检查的115个鸡蛋中，22例(19.1%)沙门氏菌阳性，其中14例(12.2%)和8例(7%)沙门氏菌来自外壳和内容物，分别。沙门菌在蛋壳中的发生和含量及在分歧海拔之间差别不显著(p>0.05)。大多数分离株对三种以上的抗菌药有耐药性，对卡那霉素有很高的耐药性，氨苄青霉素,萘啶酸,复方新诺明,土霉素和氯霉素.
结论：结果表明，本地鸡蛋作为多重耐药沙门氏菌的来源具有潜在的重要性，并且需要在食用前进行适当的烹饪。需要进一步的研究来描述埃塞俄比亚各个农业气候带中沙门氏菌的流行病学。
