Microbiological techniques ‐ some statistical aspects

Journal of the Science of Food and Agriculture, 1969
AbstractThe testing of material in order to determine its conformity to a microbiological standard involves two main processes; selection of the samples of material to be tested, and the testing of this material. For the procedure to be reliable, the sampled material must be representative of the whole and the test must give a reliable result.

Techniques for Oral Microbiology

2020
In recent years, with the rapid development of molecular biology, microecology, systems biology, and other disciplines, oral microbiology has been transformed from the traditional microbiology which is based on isolation and culture to a modern oral microbiology which is interdisciplinary and multi-scale.

Techniques in Anaerobic Microbiology

1987
The knowledge accumulated in a scientific subject is restricted by advances in experimental technique. Our information concerning the strict anaerobes has been severely limited by inadequate methods of sampling and culturing. Only in the past 30 years, and particularly the last 15 years, has sufficient attention been paid to ensuring that optimum ...

Advanced Molecular Microbiology Techniques

2014
Complimentary DNA (cDNA) is the DNA synthesised from messenger RNA (mRNA). The reaction is catalysed by two enzymes; reverse transcriptase as well as DNA polymerase. As per the central dogma of life, DNA is transcribed to mRNA, which is subsequently translated to proteins to carryout the cell’s functions.

[New microbiological techniques].

Der Urologe. Ausg. A, 2018
Microbiological diagnostic procedures have changed rapidly in recent years. This is especially true in the field of molecular diagnostics. Classical culture-based techniques are still the gold standard in many areas; however, they are already complemented by automated and also molecular techniques to guarantee faster and better quality results.

Microbiological Sampling Techniques

1989
The purpose of microbiological sampling is to allow statements of density, types and locations of microorganism which reside on the skin. The problem is that different answers are given by different sampling techniques. In laboratory experiments microorganisms are grown in ideal homogeneous culture conditions and a single sample of the culture will ...

New microbiological techniques for hospital epidemiology

European Journal of Clinical Microbiology, 1987
Infection control teams rely on microbiology laboratories for accurate, reproducible data to trace the spread of microorganisms in the hospital. Since few problems are recognized immediately, laboratories should save important nosocomial pathogens so that outbreak strains will be available for analysis by more sophisticated techniques, particularly ...

MICROBIOLOGICAL BARRIER TECHNIQUES

1965
Abstract : Microbiological barriers prevent the migration of microbial contaminants. Historically, the use of barriers in laboratory operations was documented as early as in the 19th century. In relation to the steps normally taken to detect and control microbiological contamination, the tests used with microbiological barrier systems include air ...

Comparative Study of Subgingival Microbiological Sampling Techniques

Journal of Periodontology, 1992
The presence of specific bacteria in subgingival plaque has been used as an indicator of active periodontal disease. The technique of subgingival sampling may conjecturally influence the identification and enumeration of microorganisms reported. In this study, paper point sampling and sealer sampling are compared. Subgingival samples using both methods

Oilfield Microbiology: Molecular Microbiology Techniques Used During a Biocide Evaluation

Offshore Technology Conference Asia, 2018
Abstract Biocide chemicals are an essential control in the oil and gas industry. From drinking water to hydrocarbon production streams, it is necessary to use the correct chemical, at the correct dose to prevent uncontrolled microbiological activity.
