Enumeration of Fungi in Fruits by the Most Probable Number Method
Journal of Food Science, 2010Abstract: In this study, enumeration methods for fungi in foods were evaluated using fruits that are often contaminated by fungi in the field and rot because of fungal contaminants. As the test methods, we used the standard most probable number (MPN) method with liquid medium in test tubes, which is ...

The probability of most probable numbers
European Journal of Applied Microbiology, 1975A method is described for drawing up MPN tables restricted to results with a defined minimal probability and containing 95 and 99% confidence limits calculated on the basis of probability histograms. Tables for 3, 5 and 10 tubes, respectively, in three decimal dilutions and also a table for 5 tubes in the first dilution and 1 tube in two decimal ...

Understanding and Teaching the Most Probable Number Technique1
Journal of Milk and Food Technology, 1975The most probable number (MPN) technique is extensively used in food microbiology. However, because statistics involved often are cumbersome and it is difficult to obtain some of the widely scattered literature, many individuals are not able to delve into the subject to gain a thorough understanding of the method.

Overcoming the Inflexibility of Most‐Probable‐Number Procedures
Agronomy Journal, 1990AbstractThe design of most‐probable‐number (MPN) experiments is restricted by the availability and completeness of tables for certain dilution ratio and replicate number combinations. The results presented in this paper are from a computer program, the Most Probable Number Enumeration System (MPNES), which generates solutions and confidence limits (P =

The most probable number theory
International Journal of Mathematical Education in Science and Technology, 1990Henderson et al. [1] outlined a method for the most probable number theory. In this paper some drawbacks of that method are pointed out and an alternative method is presented. Also, we show how we can relax one of the two main assumptions used in [1].

How Probable is the Most Probable Number?
Journal AWWA, 1957ple decimal dilutions. It is well known that some results occur with relatively great frequency while other results are uncommon. Too frequent occurrence of ordinarily rare results is indicative of some disturbing influence and can be used as a check on technique. 2.

Journal of Microbiological Methods, 2006
Microbial contamination of public water supplies is of significant concern, as numerous outbreaks, including Cryptosporidium, have been reported worldwide. Detection and enumeration of Cryptosporidium parvum oocysts in water supplies is important for the prevention of future cryptosporidiosis outbreaks. In addition to not identifying the oocyst species,

Graphic Evaluation of Most Probable Numbers
Journal AWWA, 1965As of this year (1965), 50 years have elapsed since McCrady laid the foundations for the application of statistical methods for the bacteriologic examination of water by the fermentation tube method. These methods furnished the basis for all further attempts, including those discussed in this article, to estimate coliform‐organism densities by ...

Estimation of Bacterial Densities by Means of the "Most Probable Number"
Biometrics, 1950THIS PAPER attempts to give a simple account of the concept of the "most probable number" (m.p.n.) of organisms in the dilution method. The concept is quite old, going back to McCrady (4) in 1915, and has been discussed by various writers from time to time, so that little of what I shall present is new. In addition, some advice is given on the planning
