It is essential for almost all experiments involving cells to count the exact cell number per milliliter suspension. In addition, it is frequently necessary to determine the number of viable cells in a cell suspension. Various procedures are available for this purpose. One of them, described ...
TVC generally underestimated the total cell count by 50 to 500 fold. Conclusion Half of the water samples from DUWS exceeded recommended levels of TVC. However, ATP and endotoxin concentrations in DUWS water samples did not correlate with these TVC data and therefore could not be recommended as ...

Determination of the total viable cell count of fresh and processed meats by a direct membrane filtration epifluorescent method was assessed. Use of 2 fluorescent dyes (acridine orange and Baclight) in the technique was also examined. Samples of cooked ham, beef mince, bacon rashers and frozen ...
Colony forming units (CFU) only detect viable cells in contrast to the TCC assay which estimates total microbial contamination. The results show that the total cell count is a reliable and sensitive method to investigate the indoor environment. 展开 ...
0.1 mL of the suspension was spread onto duplicate agar plates to give a quantitative total viable count (TVC). All were assayed using TSA plates except M. pneumoniae, which was assayed using Eaton's agar plates. • B. atrophaeus: The PBS suspension was further serially diluted ...
Bronchoalveolar lavage (BAL) is a diagnostic method for the assessment of the lower respiratory airway health status in horses. Differential cell count and sometimes also total nucleated cell count (TNCC) are routinely measured by time-consuming manual m
This chapter describes the sources of bacteria in milk (mastitis organisms, environmental contamination, and dirty milking equipment), compares total bacterial count (TBC) testing with Bactoscan and shows how bulk tank analysis of milk can help to identify the cause of high Bactoscan counts. Also...

total intact/viable bacteria and 40% of intact/viable fungi could be cultured, while the remainder were viable but yet to be cultured (Additional file1: Figure S1C). Fig. 3 Intact cell membrane/viable bacterial and fungal population aboard the ISS as estimated by PMA-qPCR.aScatter plot ...
