Bacterial colony counting using distance transform
International Journal of Bio-Medical Computing, 1995A distance-transform based technique is presented for the segmentation of monochrome images of colonies grown on membrane filters. This is used to count the number of Escherichia coli in a given water sample, which is used as a parameter for determining water quality. The result is compared with fuzzy c-means clustering approach.

Computer Methods and Programs in Biomedicine, 2001
Determination of the number of colonies (colony forming units, CFU) is a standard method in microbiological analysis to ensure the quality of drinking water. Normally this tedious work is still performed manually. A PC-based method for the automated counting of digitized images of Petri dishes is presented.

Models for microbiological colony counts
Journal of Agricultural, Biological, and Environmental Statistics, 2005Concentrations of microorganisms can be estimated from colony counts at different dilutions. However, complications can occur because of colony overlap or inhibition of colony growth. We develop a model of inhibition in which colonies fail to develop if spores are close to spores of other inhibitory species.

Urology, 1975
Evidence presented herein suggests that: (1) If the Gram stain of the spun urinary sediment is negative, there is no need to do a culture, sensitivity test, and colony count since significant bacteriuria and urinary infection are not present. There are very few false negative results. (2) Since there are many false positive Gram stains, the test is not

Bacterial colony counting by Convolutional Neural Networks
2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015Counting bacterial colonies on microbiological culture plates is a time-consuming, error-prone, nevertheless fundamental task in microbiology. Computer vision based approaches can increase the efficiency and the reliability of the process, but accurate counting is challenging, due to the high degree of variability of agglomerated colonies.

Ten-Second Urine Culture and Colony Count
Archives of Pediatrics & Adolescent Medicine, 1964The early diagnosis of urinary tract infection and its rational therapy are dependent upon the qualitative and quantitative urine culture. 1,5 The unreliability of symptoms and the inconstancy of pyuria 5,15 have resulted in the emergence of persistent bacteriuria as the most reliable index of urinary infection.

Colony counting on hydrophobic grid-membrane filters
Canadian Journal of Microbiology, 1983A device to facilitate manual scoring of hydrophobic grid-membrane filters (HGMF) is described. Variations in scores were generally less than 2.5% between 41 analysts from six laboratories, who, using the apparatus, scored a set of five specimen HGMF in different ways, and there was good agreement between scores from positive and negative grid-cell ...
