Diversity of Lactic Acid Bacteria Associated with Fresh Coffee Cherries in TaiwanCurrent Microbiology - Tập 68 - Trang 440-447 - 2013
Kun-hon Leong, Yi-sheng Chen, Shwu-fen Pan, Jen-jye Chen, Hui-chung Wu, Yu-chung Chang, Fujitoshi Yanagida
A total of 102 lactic acid bacteria (LAB) were isolated from three different coffee farms in Taiwan. These isolates were classified and identified by the restriction fragment length polymorphism analysis and sequencing of 16S ribosomal DNA. Heterofermentative Leuconostoc, and
Weissella species were the most common LAB found in two farms located at an approximate altitude of 800 m. ...... hiện toàn bộ
Bluetongue virus: Detection of antiviral immunoglobulin G by means of enzyme-linked immunosorbent assayCurrent Microbiology - Tập 4 - Trang 381-385 - 1980
JaRue S. Manning, Martin F. Chen
An enzyme-linked immunosorbent assay was developed to detect antiviral IgG in the sere of sheep exposed to bluetongue virus. It was found that the enzyme-linked immunosorbent assay is a rapid and sensitive method for the detection of anti-bluetongue virus antibody. Bluetongue virus antigen prepared from extracts of virus infected BHK and Vero cells were equally effective. Antigen prepared from uni...... hiện toàn bộ
Flow-Cytometric Method for Viability Analysis of Mycoplasma gallisepticum and Other Cell-Culture-Contaminant MollicutesCurrent Microbiology - Tập 78 - Trang 67-77 - 2020

Mycoplasma is the smallest self-replicating bacteria, figuring as common contaminant of eukaryotic cell cultures. Production inputs and operator’s manipulation seem to be the main sources of such contamination. Many analytical approaches have been applied for mycoplasma detection in cell cultures and also in biological products. However, unless they were validated, only indicator cell culture and ...... hiện toàn bộ
Localization and Characterization of GTP-Binding Protein CT703 in the Chlamydia trachomatis-Infected CellsCurrent Microbiology - Tập 62 - Trang 465-471 - 2010
Kun Du, FuYan Wang, Zhi Huo, Jie Wang, Wen Cheng, Ming Li, Ping Yu
To localize and characterize the GTP-binding protein encoded by the chlamydial ORF CT703 in the Chlamydia trachomatis-infected cells, the gene coding for CT703 in the Chlamydia
trachomatis serovar L2 genome was cloned into the prokaryotic expression vector pGEX and expressed as GST fusion protein in the E. coli BL21 strain. The GST-CT703 fusion protein was purified and used...... hiện toàn bộ
Optically Trapped Bacteria Pairs Reveal Discrete Motile Response to Control Aggregation upon Cell–Cell ApproachCurrent Microbiology - Tập 69 - Trang 669-674 - 2014
Maria Dienerowitz, Laura V. Cowan, Graham M. Gibson, Rebecca Hay, Miles J. Padgett, Vernon R. Phoenix
Aggregation of bacteria plays a key role in the formation of many biofilms. The critical first step is cell–cell approach, and yet the ability of bacteria to control the likelihood of aggregation during this primary phase is unknown. Here, we use optical tweezers to measure the force between isolated Bacillus subtilis cells during approach. As we move the bacteria towards each other, cell motility...... hiện toàn bộ
A Genomically Modified Marker Strain of Escherichia coliCurrent Microbiology - Tập 37 - Trang 341-346 - 1998
David Ammons, Joanne Rampersad, George E. Fox
Contamination of the environment with human sewage represents a serious public health concern in which Escherichia coli plays a central role, either directly as a human pathogen or indirectly through its use as an indicator organism. There is thus an ongoing effort to better understand the behavior of E. coli within such environments. Useful to such studies is the ability to readily detect a spec...... hiện toàn bộ
Transcriptional Regulation of β-Glucanase Activity in the Ruminal Bacterium, Prevotella bryantii B14Current Microbiology - Tập 50 - Trang 155-159 - 2005
Matthew W. Fields, James B. Russell
The ruminal bacterium, Prevotella bryantii B14, grew more rapidly with glucose as an energy source than mannose (0.73 versus 0.47 h−1) and had 8-fold less β-glucanase activity (50 versus 400 nmol reducing sugar mg protein−1 min−1). Cultures that were provided with glucose and mannose had little β-glucanase activity even though both sugars were utilized simultaneously. The observation that glucose ...... hiện toàn bộ
Evaluation of Herpes Simplex Detection in Corneal Scrapings by Three Molecular MethodsCurrent Microbiology - Tập 52 - Trang 379-382 - 2006
Amina Mostafa Abd El-Aal, Maysaa El Sayed, Eglal Mohammed, Mohammed Ahmed, Mona Fathy
Herpes simplex virus (HSV)-1 keratitis (HSK) is a sight-threatening ocular infection with worldwide occurrence. A prompt laboratory diagnosis is often very useful. The purpose of this study was to evaluate molecular methods as rapid diagnostic tools compared with cell culture of HSK. Corneal scrapings from patients with clinically suspected HSK were tested by direct immunofluorescence assay (IFA) ...... hiện toàn bộ
