OBJECTIVE
To assess the enteric bacteria, methicillin resistant S. aureus and antimicrobial susceptibility patterns from buses surfaces in Mekelle, Tigray, Ethiopia.
RESULTS
A total of 300 swab samples were collected from the handle surfaces of the six city buses. The bacterial isolates revealed from the swab samples were E. coli, Enterobacter spp. and S. aureus. The overall positivity rates of E. coli, Enterobacter spp. and S. aureus were 8 (4%), 4 (1.3%) and 54 (18%) respectively. Methicillin resistant S. aureus was seen in 17 (5.7%) of the total 300 swab samples collected and 17 (31.5%) of the S. aureus isolates. All (100%) of the isolates of E. coli and Enterobacter spp. showed resistance for ampicillin and three-fourth of the isolates of E. coli and Enterobacter spp. displayed resistance for chloramphenicol (75%). Five antimicrobials (ampicillin, chloramphenicol, tetracycline, ciprofloxacin, and cotrimoxazole) have showed resistant for one isolate of E. coli. Likewise four antimicrobials (ampicillin, chloramphenicol, ciprofloxacin, and cotrimoxazole) have revealed resistant for one isolate of Enterobacter spp. Moreover, three isolates of S. aureus were also found resistance to four antibiotics.
目的
评估埃塞俄比亚提格雷州梅凯勒市公交车表面的肠道细菌、耐甲氧西林金黄色葡萄球菌及抗菌药敏模式。
结果
从六辆城市公交车的把手表面共采集了300份拭子样本。拭子样本中分离出的细菌为大肠杆菌、肠杆菌属和金黄色葡萄球菌。大肠杆菌、肠杆菌属和金黄色葡萄球菌的总体阳性率分别为8例（4%）、4例（1.3%）和54例（18%）。在所采集的300份拭子样本中，有17份（5.7%）检测出耐甲氧西林金黄色葡萄球菌，在金黄色葡萄球菌分离株中有17份（31.5%）检测出该菌。所有（100%）大肠杆菌和肠杆菌属分离株对氨苄西林耐药，四分之三的大肠杆菌和肠杆菌属分离株对氯霉素耐药（75%）。五种抗菌药物（氨苄西林、氯霉素、四环素、环丙沙星和复方新诺明）对一株大肠杆菌耐药。同样，四种抗菌药物（氨苄西林、氯霉素、环丙沙星和复方新诺明）对一株肠杆菌属分离株耐药。此外，还发现三株金黄色葡萄球菌对四种抗生素耐药。
