Abstract

Escherichia coli are normal flora in the digestive tract of animals and humans but can be opportunistic under certain conditions. Apart from normal flora, there are also pathogenic strains of the E. coli bacteria that can cause disease in the hospes. The disease that can be caused by E. coli bacteria is colibacillosis which often occurs in poultry. One of the clinical symptoms that appear in chickens suffering from colibasillosis is diarrhea which can arise due to enteritis. This study aims to identify the incidence of colibacillosis and antibiotic resistance of E. coli bacteria in Free-range Chicken. Clinical symptoms showed that the animal looked weak, had diarrhea, and had feces around the cloaca. The necropsy results showed the presence of hemorrhage in the duodenum and caecum. Samples of organ swabs that experienced hemorrhage were then tested for isolation and identification of E.coli bacteria and antibiotic resistance using the Kirby-Bauer method for five types of antibiotics, penicillin, bacitracin, gentamicin, cefadroxil, and ciprofloxacin. The test results showed that the Free-range Chicken had colibacillosis. The E. coli bacteria that cause colibacillosis were resistant to penicillin and bacitracin antibiotics, intermediates to cefadroxil, and sensitive to ciprofloxacin and gentamicin.
散养鸡大肠杆菌病鉴定及耐药性试验
大肠杆菌是动物和人类消化道中的正常菌群,但在某些条件下可能是机会性的。除了正常的菌群外,还有大肠杆菌的致病性菌株,可以在医院引起疾病。大肠杆菌引起的疾病是大肠杆菌病,常发生在家禽中。感染大肠杆菌病的鸡的临床症状之一是腹泻,这可能由肠炎引起。本研究旨在确定散养鸡大肠杆菌病的发病率和抗生素耐药性。临床症状显示该动物身体虚弱,有腹泻,泄殖腔周围有粪便。尸检结果显示十二指肠和盲肠出血。然后使用Kirby-Bauer法对出血的器官拭子样本进行大肠杆菌的分离和鉴定以及对五种抗生素(青霉素、杆菌肽、庆大霉素、头孢丙沙星和环丙沙星)的耐药性检测。测试结果显示,该只散养鸡感染大肠杆菌病。引起大肠杆菌病的大肠杆菌对青霉素和杆菌肽类抗生素耐药,对头孢丙沙星的中间体耐药,对环丙沙星和庆大霉素敏感。
