Journal of Microbiological Methods, 1996
Abstract We propose a spectrofluorimetric method for the determination of the counts and biomass of microbial cells in natural water, mud and soil samples. The method is based on the use of the fluorescent dye, fluorescamine, which reacts specifically with proteins and amine acids of microbial cells.

Electrochemical Microbial Sensor for Rapid Detection and Quantification of Total Bacterial Count
ECS Meeting Abstracts, 2020Early and online detection of pathogens in the agricultural sector is vital in terms of crop protection as well as economy. Within this context, an electrochemical microbial sensor with a locally formed electrocatalyst was used for rapid detection of gram-negative and gram-positive bacteria in a suspension of bacteria in water.

Influence of milking interval on the total bacterial count in a simulated automatic milking system
Journal of Dairy Research, 1999An automatic milking system (AMS) uses a robot to attach the teatcups and can be continuously available for cows to present themselves to be milked with minimal human intervention. Milking in an AMS is therefore a continuous rather than a batch process, and the conventional practice of cleaning a milking system after each batch of cows has been

Total viable bacterial count using a real time all-fibre spectroscopic system
The Analyst, 2013Rapid, accurate and sensitive enumeration of bacterial populations in the natural environment is an essential task for many research fields. Widely used standard methods for counting bacteria such as heterotrophic plate count require 1 to 8 days of incubation time for limited accuracy, while more accurate and rapid techniques are often expensive and ...

A NUMBER of workers have compared the general performance of domestic ruminants with and without ciliate protozoa. In no case was any striking difference observed. Hungate1 has suggested that bacteria may take over the activities of the normal ciliate protozoan population, and also Bryant and Small2 observed a distinct drop in the count of cellulolytic

Effect of mastitis‐related bacteria on total bacterial count of bulk milk supplies
International Journal of Dairy Technology, 1987Seven hundred and fifty‐four bulk milk samples from a total of 9,066 tested by the Aberdeen and District Milk Marketing Board in 1984 had total bacterial counts greater than 45,000 per ml. Of the failed samples, 43.8% had more mastitis‐related bacteria present than non‐mastitis types.

Distribution of Total Aerobic and Coliform Bacterial Counts Among Rice Kernel Components
Journal of Food Science, 1998ABSTRACTNine lots of long‐grain rice were milled, and the basic rice components (hulls, bran, brokens, and head rice) were segregated. Serial dilutions of ground samples were conducted to determine aerobic plate counts (APC) and coliform counts. Significant differences (p<0.05) in bacterial counts were found between the components for both APCs and ...

The diagnosis of spontaneous bacterial peritonitis (SBP) in patients with ascites is established by definition with a polymorphonuclear (PMN) cell count in the ascitic fluid greater than 0.250 g/l determined via cytological (microscopic) examination. In this study, we correlated the automatically assessed total ascitic nucleated cell count with PMN and

Milk samples were collected in the dry season (n = 155) and in the rainy season (n = 68) to establish a correlation between electronic flow cytometry and standard plate count for the determination of total bacterial count of raw milk. Results were expressed in individual bacterial count (ibc) and colony forming unit (cfu) for electronic flow cytometry

A. H. Coons et al. introduced the use of fluorochrome-conjugated antibodies, and in 1942 introduced the fluorescein isocyanate-labeled antibodies. These labeled antibodies were used to stain tissues of mice, heavily infected by pneumococci. There are two ways of making the target antigen "visible" by use of fluorochrome-labeled antibodies: the direct ...
