香烟烟雾对那些被认为是常见的潜在人类病原体的细菌种类的生长的影响在体外进行了检查。 从薄荷和nonmentholated香烟烟雾抑制革兰氏阳性球菌的生长，以更大的程度比革兰氏阴性杆菌。 金黄色葡萄球菌、肺炎链球菌和多种其他链球菌在1：8的烟溶液稀释度下被抑制。 克雷伯氏菌、肠杆菌和假单胞菌等肠道细菌不受1：1稀释溶液的影响。 与革兰氏阳性球菌一样，奈瑟氏菌属和布兰汉氏菌在1：8稀释度下也受到抑制。 15名吸烟者和15名非吸烟者的口腔培养结果表明，吸烟者有发展严重的革兰氏阴性细菌定植的倾向。
The effect of cigarette smoke on growth of those species of bacteria that are considered common potential human pathogens was examined in vitro. Smoke from both mentholated and nonmentholated cigarettes inhibited the growth of Gram-positive cocci to a greater degree than that of Gram-negative rods. Staphylococcus aureus, Streptococcus pneumoniae, and a variety of other streptococci were inhibited at a smoke solution dilution of 1:8. Enteric bacteria such as Klebsiella, Enterobacter, and Pseudomonas were not affected by a 1:1 dilution of the solution. As with the Gram-positive cocci, the Neisseria species and Branhamella were also inhibited at a dilution of 1:8. Culture results of the mouth of 15 smokers and 15 nonsmokers showed that the smokers have a propensity to develop heavy Gram-negative bacterial colonization.
