gram negative bacteriagram positive bacteriaphylogenytaxonomyBacterial nomenclature has been loose and unsystematic; the terms in common use do not have the significance that applies to terminology in other branches of biology. One of the reasons for this unsatisfactory state is that the identification ...
Gram reaction: Gram-positive and Gram-negative bacteria respond to different antibiotics. Other bacteria (e.g. mycobacteria) may require special staining techniques. Cell shape: Bacteria may be shaped as cocci, bacilli or spirals. Endospore: The presence, shape and position of the endospore within...
SUMMARY: Some factors which affect the results of carbon source utilization (CSU) tests were investigated with 187 strains of Gram-negative bacteria, chiefly non-fermentative. There was little difference between the results at 37 and 30°C. Repetition of tests showed that 5% of the results were...
The article discusses a study which examines the classification and identification of two-component systems (TCSs) in bacteria and the distinctions of their domain structures. Findings reveal that the domain structures of about 360 bacteria and 43 archaea were identified while 8,573 histidine ...
Recently, imaging-based approaches started to be applied for antimicrobial MoA prediction. Bacterial cytological profiling was developed for Gram-negative bacteria to classify antimicrobial agents, utilizing high resolution fluorescent microscopy of cells stained with fluorescent dyes, or expressing fluorescent ...
Bacteria are prokaryotic, single-celled microscopic organisms present almost everywhere. Explore the structure of bacteria, classification of bacteria and its reproduction.
For example, recognition of Porphyromonas gingivalis as a unique species, separate from its previous inclusion within Bacteroides melaninogenicus (now known to be composed of several taxonomic groups of black-pigmenting anaerobic gram-negative bacilli), elucidated its role as a key pathogen in adult ...
Herein, we developed optical property–superior and heavy metal–free ZnCuInSe quantum dots (QDs) for achieving rapid discrimination of Gram-positive/Gram-negative bacteria by the naked eye; driven by the structural differences of bacteria, ZnCuInSe QDs are effective in binding to Gram-positive ...
A new case history in the taxonomy of gram-negative bacteria. Various criteria that have been used in the development of a system of classification of Pseudomonas species, as well as in the precise circumscription of ... NJ Palleroni - 《Antonie Van Leeuwenhoek》 被引量: 207发表: 1994年 ...
Since the spectral signatures of different serotypes tend to be separated, support vector machine (SVM) classifier was employed for classification of Gram-positive and Gram-negative bacterial species [12]. In addition to spectral data analysis, morphological features of different bacterial species were...
