山区农村饮水水质的净化方法

水是生活中必不可少的物质,特别是日常生活用水。在利用水时,由于水源不同,考虑水质好坏是很重要的问题。山区农村的饮用水源较城市更为复杂,如有河水、泉水、水库水、旱井水、矿坑水等等,若水质不良将严重影响人民的身体健康,为了改善和预防水土病,现介绍我省山区农村在净化水质方面的一些经验供各地参考。     

鲍曼不动杆菌毒力因子研究进展

Acinetobacter baumannii is an important condition opportunistic pathogen widely distributing in human living environment. Because of its strong drug-resistant character, it has always been a hot topic in the biomedical research field. However, little knowledge of its virulence factors is known comparing to the drug-resistance research. Acinetobacter baumannii can survive for a long time in host and cause serious damage to host cells after invading the host, so virulence factors might play an important role during the invasion, proliferation and injure process. Here, we summarized the advanced researches and progresses on virulence factors of Acinetobacter baumannii for benefiting future study of its pathogenic mechanisms, providing new ideas for the potential treatment and screening drugs of diseases caused by Acinetobacter baumannii.     

小兴安岭大型真菌多样性及地理区系

在小兴安岭地区采集大型真菌标本645份，经分类鉴定出437种，由399种担子菌和38种子囊菌组成。其中，优势科有14科，占小兴安岭地区总科数的20.59%;优势科共含284种，占总种数的64.99%。优势属有22属，占小兴安岭地区总属数的13.84%;优势属共含214种，占总种数的48.97%。小兴安岭地区属的区系地理成分分为5个分布类型，以世界广布成分(55.35%)为主，其次为北温带成分(32.70%)。种的区系地理成分共8个分布类型，以北温带分布成分(51.26%)为主，其次为世界广布成分(32.27%)。小兴安岭地区属级、种级成分主要以世界广布和北温带分布为主，说明该区的大型真菌具有明显的世界广布和北温带性质，且该地区具有丰富的大型真菌生物多样性。
