Abstract

Antibacterial resistant bacteria cause a big concern to poultry and to public health in general because some bacterial poultry pathogens can infect humans or transfer their resistance ability to human pathogens. Nontherapeutic use of antibacterial in poultry, especially as growth promoters to increase feed conversion efficiency is thought to be one of the main causes of resistance. The study included pulmonary swab samples collected during necropsy from 120 poultry farms showing respiratory symptoms with mortality. The disc diffusion method for antibiotic sensitivity testing was performed and antibiotic disks for 21 antibiotics were used. The results showed that three antibacterial were sensitive to more than 50% of the isolates. The first is doxycycline and 69.9% of the isolates were sensitive. The second is Cefalexin with 60.5% sensitive isolates and third is Chloramphenicol with 55.2% sensitive isolates. In the rest of antibacterial, less than 50% were sensitive. Five isolates were found resistant to all antibacterial. Moreover, three samples were found to be negative with no bacterial growth. The present study concluded that 50% of the aerobic bacteria isolated from poultry lungs are resistant to 85% of the 21 antibiotics tested in the study.

肉鸡肺中需氧细菌分离株的抗菌素耐药性

抗菌耐药细菌对家禽和一般公共卫生造成了很大的关注，因为一些细菌性家禽病原体可以感染人类或将其耐药能力转移给人类病原体。在家禽中非治疗性使用抗菌药物，特别是作为生长促进剂以提高饲料转化效率，被认为是产生耐药性的主要原因之一。该研究包括在尸检期间从120个家禽养殖场收集的肺拭子样本，这些家禽养殖场出现呼吸道症状并死亡。采用纸片扩散法进行抗生素敏感性试验，共使用21种抗生素纸片。结果表明，3种抗菌药物对50%以上的分离菌敏感。第一是强力霉素，69.9%的菌株敏感。其次是头孢氨苄(60.5%)，第三是氯霉素(55.2%)。其余抗菌药物中，敏感者不足50%。5株菌株对所有抗菌药物均有耐药性。另外，3份样品检测结果为阴性，没有细菌生长。目前的研究得出结论，从家禽肺部分离出的需氧细菌中有50%对研究中测试的21种抗生素中的85%具有耐药性。
