Automated turbidimetry for the rapid differentiation and enumeration of bacteria in food

Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1989
A fully automated analysis system has been used to determine bacterial contamination in food, both qualitatively and quantitatively. Growth curves of bacterial flora were monitored using differential media, and a correlation was established between growth curve parameters and colony-forming units derived from drop-plating as the reference method ...

Advances in leukocyte differential and peripheral blood stem cell enumeration

Current Opinion in Hematology, 1996
Automated leukocyte differential counting has resulted in a marked improvement of the precision of leukocyte subclass enumeration. With advancement of this technology, algorithms have been developed to identify samples that require manual microscopic review.

AN AGAR MEDIUM FOR THE DIFFERENTIAL ENUMERATION OF YOGURT STARTER BACTERIA1,2

Journal of Milk and Food Technology, 1974
Generally, Streptococcus thermophilus ferments sucrose, whereas Lactobacillus bulgaricus fails to utilize this disaccharide. When both sucrose and lactose were added to a basal medium, S. thermophilus fermented both carbon sources, produced sufficient acid to change the color of an acid-base indicator (bromcresol purple), and hence formed yellow ...

Enumeration, Kinematic, Static and Mechanical Efficiency Analysis of Differential Screw Mechanisms

Journal of Mechanisms and Robotics, 2009
Although differential screw mechanisms are widely used in precision mechanisms to control fine relative movements, their enumeration and systematic methods of analysis seem less widespread. In this paper methods to support the preliminary design steps of these devices are proposed.

A method for the differential microscopic enumeration of Halobacterium cells

Journal of Microbiological Methods, 1989
Abstract When hypersaline brines are treated with low concentrations of bile salts, such as sodium deoxycholate or sodium taurocholate, Halobacterium and related halophilic archaebacteria lyse while both halophilic eubacteria and halococci remain intact.

Comparison of two selective media for the recovery, isolation, enumeration and differentiation of Rhodococcus equi

Veterinary Microbiology, 2007
The use of selective media to facilitate the isolation of Rhodococcus equi from environmental and clinical samples has aided studies of the ecology of R. equi and the epidemiology of disease caused by R. equi. Here, we compared the efficacy of two selective media (NANAT and modified CAZ-NB) for the recovery of six defined strains of R. equi and for the

Development of a selective and differential media for the isolation and enumeration of Bacillus cereus from food samples

Journal of Applied Microbiology, 2020
Identification and enumeration of foodborne pathogens in food stuffs are valuable concerns. In the present study, starch-blood-egg yolk-polymyxin B-trimethoprim-ceftazidime (SBYPTC) agar was established to isolate and specify the number of Bacillus cereus in food products.The effectiveness of the developed medium in selecting for B.

Differential fluorescence nanoparticle tracking analysis for enumeration of the extracellular vesicle content in mixed particulate solutions

Methods, 2020
A major concern for the extracellular vesicle (EV) field is the current lack of accurate methods for EV quantification. Total protein measurement fails to reliably quantify EVs from serum-containing conditioned media and classical nanoparticle tracking analysis (NTA) allows quantification and size determination of particles, but fails to discriminate ...

On the differential equations for the transition probabilities of Markov processes with enumerably many states

Mathematical Proceedings of the Cambridge Philosophical Society, 1953
Letpik(s, t) (i, k= 1, 2, …;s≤t) be the transition probabilities of a Markov process in a system with an enumerable set of states. The states are labelled by positive integers, andpik(s, t) is the conditional probability that the system be in statekat timet,given that it was in stateiat an earlier times.If certain regularity conditions are imposed on ...

Evaluation of Six Cytometric Methods for Reticulocyte Enumeration and Differentiationin the Cat

Veterinary Clinical Pathology, 1995
Six protocols utilizing three fluorescent nucleic acid dyes (thiazole orange, auramine O, and acridine orange) were evaluated by flow cytometry for clinical utility in the analysis of feline reticulocytes. The dyes showed good to poor correlations with each other and with manual counts. Thiazole orange was the preferred stain.
