次培养

In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.

结果表明，嗜热链球菌在营养丰富的培养基中的生长延滞期缩短，到达对数生长顶点的时间变短，稳定期的时间延长，当经过二次培养后，嗜热链球菌几乎不经过延滞期直接到达对数期，平稳期持续的时间较短，很快到达衰亡期；嗜热链球菌在超浓缩培养过程中三大营养物质的代谢规律也同它的培养过程有很大的关系，菌数多，其代谢旺盛，菌数降低其代谢速度减慢；嗜热链球菌在超浓缩培养过程中存在着明显的菌体形态变化，并可能存在着细胞凋亡，与菌体增殖和产酸规律密切相关，随着培养时间延长，培养基中营养物质变得贫乏，菌体形态变化和细胞凋亡的情况愈加明显。

METHODS: The rib trabeculae were resected and broken, trypsinizated and washed completely by PBS. Bone surface and non-adhesive floating cells in cleaning fluid were observed with inverted microscope. Rib trabeculae was washed by DMEM culture medium once, and cultured in culture bottle. The culture liquid was replaced by new one once a week. The osteoblast was moved from the sclerite a week later. The cells were fused monolayer and could be subcultured 4 to 6 weeks later.

METHODS: Rat bilateral olfactory bulbs and olfactory mucosa at 1/3 nasal septum were obtained, sliced, digested in trypsin, and made into monoplast suspension. At 1×109/L, cells were incubated in uncoated 25 cm2 culture flask. At 18-20 hours, cell suspension was moved into another uncoated 25 cm2 culture flask (the first differential adhesion). At 24 hours, cell suspension was moved into a poly-D-lysine-coated 25 cm2 culture flask or poly-D-lysine-coated 6-well culture plate (the second differential adhesion). At 48 hours, parenchyma cells were removed after a half of medium was changed.

Subsequently, the performance of the Pastorex Staph-Plus agglutination test with presumptive MRSA isolates taken directly from chromogenic agars was compared to that of the Pastorex Staph-Plus agglutination test with isolates from blood agar subcultures (conventional_Pastorex agglutination).

紧接着，使用Pastorex Staph-Plus葡萄球凝集试剂检测直接从显色平板上挑取的疑似MRSA菌落（称之为直接Pastorex 凝集），并与次培养到血平板上的菌落的Pastorex Staph-Plus凝集试验（称之为传统Pastorex 凝集）的结果进行比较。

Results In 136 patients, a total of 72cases sputum culture positive, the positive rate of 52.9% sputum culture for three consecutive single bacteria were 16 cases, the positive rate of 11.8%.16 patients sputum results were:hemolytic streptococcus 6 cases, 4cases of Pseudomonas aeruginosa , Klebsiella pneumoniae in 2 cases and gas production Bacillus 2 cases , Enterobacter Bacillus 2 cases, 136 patients with 386 cases sputum culture times , 106 times positive(27.5%), and consecutive three or more times a train 4 the same bacteria ,only 42 cases(10.8%); the same single-64 cases sputum culture , which amounts to 16.6%.
