摘要

为了保持卫生生活,遵守卫生规则是很重要的。手部卫生是保持个人卫生最必要的部分之一。由于手直接用于人与人之间的接触,与动物接触,准备食物等,它们可以将微生物传播到所有这些接触源。因此,如果保持适当的手部卫生,微生物的传播将会减少,这最终可以减少一些病原微生物直接从自身或从处理后的动物传播给易感宿主。感染有害致病菌的易感人群如果找到适当的进入途径,就会生病。在制备食物和进餐过程中,微生物可通过手进入人体,手污染食物的微生物可在食物中增殖,使食物变质,并释放出毒素,分别引起食源性感染和食源性中毒。为了减少这种风险,人们需要经常洗手,特别是在食品加工区域,应该用水和肥皂洗手,这样可以更好地清洁。现在人们在用水洗手后使用即时洗手液提供额外的保护。洗手液在没有明显污垢的手上效果最好。在目前的研究中,选择了五种含酒精的洗手液来确定这些洗手液减少五位志愿者手上微生物负荷的能力。研究发现,含酒精的免洗洗手液确实减少了手部微生物菌群的负荷,但并没有达到令人满意的水平。即使它们对某些致病菌的效果也很低。这些产品只能在没有水的地方使用,以减少手上的微生物负荷。微生物学报,Vol.8(1) 2018: 10-14

Effectiveness of different instant hand sanitizers against normal flora and some selected pathogenic bacteria
To maintain hygienic life it is important to follow the rules of sanitation. Hand sanitation is one of the most necessary parts of keeping personal hygiene. As hands are used directly for person to person contact, contact with animals, food preparation and so on, they can transmit microorganisms to and from all of these sources coming in contact. So if proper hand sanitation is maintained, the transfer of microorganisms will be decreased which can ultimately reduce the transmission of some pathogenic microorganisms to a susceptible host from own self directly or from the animals after handling them. Susceptible people getting harmful pathogenic bacteria can get sick if they find their appropriate routes of entry into them. During food preparation and taking meals, microorganisms can get entrance into the body from hands as well as microbes contaminating foods from the hands can proliferate in the foods causing spoilage and also release toxins causing food borne infection and food borne intoxication respectively. To reduce such risks people need to wash hands on routine basis especially on food processing zone it should be washed with water and soap which results in greater cleaning. People now use instant hand sanitizer after washing hands with water giving an extra protection. Sanitizers works best on hands with no visible sign of dirt. In the current study, five alcohol based hand sanitizers were selected to determine the ability of these sanitizers to decrease the loads of microorganisms from the hands of the five selected volunteers. During the study, it has been found that alcohol based instant hand sanitizer do decrease the loads of microbial flora from the hands but not in satisfactory level. Even they possessed very low effectivity against some pathogenic bacteria. These products can be used only where water is not available to decrease the loads of microbes from the hands.
