Diseases caused by () and spp. can negatively impact turkey farming. The aim of this study was to isolate and characterize multidrug-resistant (MDR) and spp. in healthy and diseased turkeys. A total of 30 fecal samples from healthy turkeys and 25 intestinal samples from diseased turkeys that died of enteritis were collected. Bacterial isolation and identification were based on biochemical properties and polymerase chain reaction (PCR). Antibiogram profiles were determined by disk diffusion. The tetracycline-resistance gene was detected by PCR. All samples were positive for . Only 11 samples (11/30; 36.67%) were positive for spp. from healthy turkeys, whereas 16 (16/25; 64%) samples were positive for spp. from diseased turkeys. isolated from diseased turkeys showed higher resistance to levofloxacin, gentamicin, chloramphenicol, ciprofloxacin, streptomycin, and tetracycline. spp. isolated from healthy turkeys exhibited higher resistance to gentamicin, chloramphenicol, ciprofloxacin, streptomycin, imipenem, and meropenem. All and spp. from both healthy and diseased turkeys were resistant to erythromycin. spp. from both healthy and diseased turkeys were resistant to tetracycline. Multidrug resistance was observed in both and spp. from diseased turkeys. Finally, the gene was detected in 93.1% of the isolates and in 92.59% of the spp. isolates. To the best of our knowledge, this is the first study to isolate and characterize -gene-containing MDR and spp. from healthy and diseased turkeys in Bangladesh. Both microorganisms are of zoonotic significance and represent a significant public health challenge.
由()和 属细菌引起的疾病会对火鸡养殖产生负面影响。本研究的目的是分离并鉴定健康和患病火鸡中的耐多药(MDR) 菌和 属细菌。共收集了30份健康火鸡的粪便样本和25份死于肠炎的患病火鸡的肠道样本。细菌的分离和鉴定基于生化特性和聚合酶链反应(PCR)。通过纸片扩散法测定抗菌谱。通过PCR检测四环素抗性基因 。所有样本 均呈阳性。健康火鸡的样本中只有11份(11/30;36.67%) 属细菌呈阳性,而患病火鸡的样本中有16份(16/25;64%) 属细菌呈阳性。从患病火鸡中分离出的 菌对左氧氟沙星、庆大霉素、氯霉素、环丙沙星、链霉素和四环素表现出更高的耐药性。从健康火鸡中分离出的 属细菌对庆大霉素、氯霉素、环丙沙星、链霉素、亚胺培南和美罗培南表现出更高的耐药性。来自健康和患病火鸡的所有 菌和 属细菌均对红霉素耐药。来自健康和患病火鸡的 属细菌均对四环素耐药。在患病火鸡的 菌和 属细菌中均观察到耐多药现象。最后,在93.1%的 菌分离株和92.59%的 属细菌分离株中检测到 基因。据我们所知,这是首次在孟加拉国从健康和患病火鸡中分离并鉴定含 — 基因的耐多药 菌和 属细菌的研究。这两种微生物都具有人畜共患病意义,是重大的公共卫生挑战。
