Bacterial contamination of various parts of the cotton plant and of cotton from different mills was investigated. The predominant bacterial species were Gram-negative rods mainly of the Enterobacter genus. When guinea pigs inhaled strains of these bacteria cultivated from cotton, a strong leucocyte mobilising capacity was found for Pseudomonas and Enterobacter but not for Agrobacterium or Bacillus species. The aetiology of the development of pulmonary symptoms after inhalation of bacteria-containing dusts and subsequent production of endotoxins is discussed.
对棉花植株各部位以及来自不同工厂的棉花的细菌污染情况进行了调查。主要的细菌种类是革兰氏阴性杆菌,主要属于肠杆菌属。当豚鼠吸入从棉花中培养出的这些细菌菌株时,发现假单胞菌和肠杆菌具有很强的白细胞动员能力,而农杆菌或芽孢杆菌则没有。文中讨论了吸入含细菌粉尘并随后产生内毒素后肺部症状发展的病因。
