Calorimetric studies of microbiological systems
Using mass-cultivation and cryogenic storage, aliquots of standardised inocula giving calorimetric power-time outputs with a variability of 2 to 4% were used to test the antimicrobial efficacy of Aquacel-Ag compared with silver nitrate on P. aeruginosa, S. aureus, and a 50:50 mixed culture in both …

A microbiological decision tree approach for performing a hazard analysis and its relationship to microbiological risk analysis
The annual incidence of microbiological food borne disease in the United States ranges between 6.5 million to 33 million cases with as high as 9,000 deaths. There is a developing consensus that the Hazard Analysis and Critical Control Point (HACCP) concept is the most effective and rational means …

Microbiological Quality of Ultrasonic Dental Scaler Output Water
Objectives: Since ultrasonic dental scalers contain internal narrow-diameter waterline tubing susceptible to bacterial biofilm growth, this study determined the cultivable prevalence of aerobic mesophilic heterotrophic bacteria in ultrasonic scaler output water subjected to one of two commercial …

Controlled microbiological and environmental techniques in meat processing
… was adapted to study the influence of certain microbiological populations and their effects on processed meat. The technique consisted of an initial reduction of surface bacteria on conventionally handled muscle tissue via a hot water dip, followed by processing at 28ºC in a sterile plastic …

Microbiological evaluation of the Mhlathuze River in KwaZulu-Natal
… directly for domestic use without treatment. The microbiological, physical and chemical analysis of the Mhiathuze River was investigated over a twenty-one months period. Five water samples were collected along the Mhiathuze River and analysed to monitor the indicator bacteria pollution with …

Húsok mikrobaszennyezettségének csökkentése = Reducing of microbiological contamination of meats
Az állati eredetű élelmiszerek, s ezek közül is a húsok kémiai összetételüknél, mikrobiológiai állapotuknál fogva nagyon labilisak, könnyen romlanak, és ennek következtében eltarthatóságuk viszonylag rövid, ennek következtében jelentős tápanyagforrás veszteségek lépnek fel, ami komoly gazdasági …

The Microbiological Aspects of Early Stages of Marine Fouling
In this study, the ecology of attached marine bacterial populations on materials of economic significance was considered. Specific aspects of the microbial film examined were its composition, construction, and dynamics of bacterial attachment. Precise and practical methods for collecting data from …

Microbiological influences on phosphorus release from aerobic lake sediments
The role of sediments in regulating nutrient availability in lakes and reservoirs has been the subject of many recent studies. Classical theories concerning the regulation of phosphorus release from sediments by oxidation-reduction potential neglect the potential of microorganisms to transfer large …

Microbiological, genomic and transcriptomic analyses of human tuberculosis lung cavities
BACKGROUND: Tuberculosis (TB) remains out of control globally. Recent promising vaccine candidates have failed in clinical trials and host immunity in the lung remains poorly understood. Pathogenesis of pulmonary cavitation, the basis of TB transmission, is poorly understood. The degree of …

Raman spectroscopy for the microbiological characterization and identification of medically relevant bacteria
<p>The detection and identification of pathogenic bacteria has become more important than ever due to the increase of potential bioterrorism threats and the high mortality rate of bacterial infections worldwide. Raman spectroscopy has recently gained popularity as an attractive robust approach for …
