棉尘症的形成受其环境影响,Cinkotai等报道棉纱厂空气细菌菌落数达10~2～10~3cfu/m~3,并从棉尘中测出内毒素浓度。Haglind等作了三家棉纱厂细菌学调查,指出棉尘症的流行与空气传播的革兰氏阴性杆菌和棉尘程度相关。本文就棉尘症环境细菌学调查报告如下。1 材料与方法1·1 标本 无锡市第七和第四棉纺织厂开棉、梳棉、并条、粗纱、细纱、筒子、回棉车间的空气标本,以及两家工厂生产所用的原棉洋马527、精落二级棉及三级棉、车肚、破籽和二、三、四级棉的棉花标本。1·2 菌落计数及细菌总数测定 The formation of cotton dust disease is affected by its environment. Cinkotai et al. Reported that the number of bacterial colonies of air in cotton yarn factory reached 10 ~ 2 ~ 10 ~ 3cfu / m ~ 3, and the endotoxin concentration was measured from cotton dust. Haglind et al. Conducted a bacteriological survey of three cotton yarn factories, pointing out that the prevalence of cotton dust disease is related to the extent of airborne Gram-negative bacilli and cotton dust. This article on cotton dust environmental bacteriology survey report is as follows. 1 Materials and Methods 1.1 Specimens Air samples from the seventh and fourth cotton spinning mills of Wuxi City to be opened, combed, drawn, roving, spun, bobbin and back to the cotton mill, and raw cotton Yanmar used in the two factories 527, refined two cotton and three cotton, belly, broken seeds and two, three, four cotton cotton specimens. 1 · 2 colonies count and total bacterial count
