ABSTRACT

A patient is in close proximity to different types of textiles in hospital environment, which contribute to the transfer of drug-resistant bacteria in healthcare settings. This study was undertaken to estimate the temporal variations in bacterial load on bedsheets in a primary healthcare unit in Delhi. Data were collected for a period of 7 months. Antibiotic susceptibility testing of isolates was performed. The mean count of Acinetobacter spp. was highest (2.10 × 10² CFU/cm²), and Klebsiella spp. showed the least mean count (7.5 × 10¹ CFU/cm²). The mean bacterial count over the period showed maximum bacterial load for most microbial groups in June, and minimum in November. Enterococcus faecalis and Streptococcus spp. were highly resistant to different antibiotics, while Acinetobacter spp. and Group A Streptococcus showed the least resistance toward the antibiotics tested. Bacterial counts on bedsheets were found to vary with the time of the year, indicating that environmental factors affect bacterial load.

摘要

患者在医院环境中靠近不同类型的纺织品，这有助于耐药细菌在医疗保健环境中的转移。这项研究旨在估计德里一家初级医疗保健单位床单上细菌负荷的时间变化。数据收集了 7 个月。对分离物进行了抗生素敏感性试验。不动杆菌属的平均计数。最高（2.10 × 10 ²  CFU/cm ²）和克雷伯氏菌属。显示最少的平均计数（7.5 × 10 ¹  CFU/cm ²）。在此期间的平均细菌计数显示，大多数微生物组的细菌载量在 6 月最大，在 11 月最小。粪肠球菌和链球菌属。对不同的抗生素具有高度抗性，而不动杆菌属。A 组链球菌对所测试的抗生素的耐药性最低。发现床单上的细菌数量随一年中的时间而变化，这表明环境因素会影响细菌负荷。
