To detect relationships between the groups of treatment performed, we carried out a principal components analysis (PCA). Cells in VBNC condition pose a public health threat because they are potentially pathogenic. Lower right side: 0% of coccoid cells (and consequently 100% comma cells). These results indicated that, increasing coccoid shape transformation, the cells varied both the metabolic and the dimension profile, delineating a triangle in the graph of the 1st and 2nd PCA (Fig. Vibrio alginolyticus belongs to the Vibrio genus in the Vibrionaceae family. The results of the pathway analysis demonstrated that the 1st principal component was highly correlated with LE and ID and the 2nd principal component was highly correlated with MO (the variables correlated with the two principal components are identifiable by the highest score coefficients in absolute value) as shown in Table 2.

This work was supported by GM107629 from the National Institute of General Medicine, and AU-1714 from the Welch Foundation (to J.L.). Furthermore, at 48 and 54 days of incubation (VBNC state), the vibrios had comparable morphology (similar 1st principal component values) but slightly varying metabolic status (different 2nd principal component values).

For the studies examining the entry of cells into a VBNC state, cells, grown as described above, were diluted 100‐folds in ASW, to obtain a starting cell number of ∼108 colony forming units per ml (CFU/ml) (14). Zuo Y, Zhao L, Xu X, Zhang J, Zhang J, Yan Q, Huang L. Emerg Microbes Infect.

This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. These results agree with those of other authors (20) as they describe the capability of AO to discriminate between DNA and RNA staining in bacteria: VBNC inactive bacteria contain mostly DNA in contrast to active growing cells which mostly contain RNA.

Most (96%) of the 1331 V. alginolyticus infections were from coastal states. Global climate change and wound care: case study of an off-season vibrio alginolyticus infection in a healthy man.

Epub 2019 Jan 31. We found that after 6–12 days of incubation, the morphology of V. alginolyticus was strongly characterized by the comma‐shaped forms (80–100%). Extraintestinal infections caused by Vibrio parahaemolyticus and Vibrio alginolyticus in a Danish county, 1987-1992. This original method combines microscope image analysis and bioinformatic software yielding data with much higher biological information content and can be proposed as large‐scale biology and high content screening tool. Comprehensive Reviews in Food Science and Food Safety. Stained samples were observed by a phase‐contrast Nikon Optiphot microscope (filter set 14; excitation BP 546/12; emission LP 590) coupled with a Hamamatsu 5985 camera, processed by NIH Scion Image 1.61 on a Macintosh 6100/66 computer to estimate shape parameters. SerialEM (50) was used to collect tilt series at ∼8 µm defocus. For each cell under measurement, the program rectangular option was selected as it allows parameter estimation.

Sample (100 μl; obtained from cells containing “microcosm water”) was fixed with paraformaldehyde (final concentration 2% v/v) for preservation and kept at 4°C until analyzed (within 1 week). PCA using multi‐parameters.

A total dose of 50 e−/Å2 is distributed among 35 tilt images covering angles from −51° to +51° at tilt steps of 3°. In fact, an explained variance higher than 65% for the first two principal components is usually considered a good result, a value higher than 80% is considered an excellent one (19).

For the analysis, the fixed samples were stained with AO (at a final concentration of 0.01% w/v) for 5 min at room temperature. 2).

We propose an original application of a statistical model (already used for erythrocyte cell shape definition (8)) to characterize morphological parameters related to the metabolic cellular state. In this way, we obtained 11 groups with different percentages of comma and coccoid morphologies with their correspondent grey density profile as a metabolic index.
