Microorganism Control

Microorganism Tracking Microscope System

Continuous observation of individual motile microorganisms is difficult, since their swimming speed is fast compared with their diameters. In fact, some bacteria can swim as fast as 50 diameters/s [1]. At this speed, microorganisms can quickly go out of the range of static measurement instruments, such as the field of view of optical microscopes. This problem can be solved by tracking the micro...

Functional Basis of Microorganism Classification

Correctly identifying nearest "neighbors" of a given microorganism is important in industrial and clinical applications where close relationships imply similar treatment. Microbial classification based on similarity of physiological and genetic organism traits (polyphasic similarity) is experimentally difficult and, arguably, subjective. Evolutionary relatedness, inferred from phylogenetic mark...

A Filterable Yeast-like Microorganism

Voltammetric measurement of microorganism populations

A voltammetric biosensor was developed for the assay of microorganism populations. A tetracycline-modified glassy carbon electrode was used in the construction of the biosensor and an electrochemical cell with an elastic base was employed in the measurement. The possible mechanism of the electrode response was discussed. The determination limit of the microbial populations was 2–5 × 104 cells w...

Blastocystis Hominis, Intestinal Parasite or Nonpathogen Microorganism?

Blastocystis hominis is a worldwide distributed microorganism with no definite host. In addition to human beings it has been diagnosed in variety of animals. This organism which is abundantly found in routine stool examinations and also 'in some cases has been identified as a factor causing severe diarrhea, earlier regarded as a fungi. Later it was distinguished as cyst of intesinal Trichomonas...
