Microbial Contamination of Toothbrushes
Journal of Dental Research, 1977Abstract : The degree of bacterial contamination of toothbrushes after contamination and storage in vented containers or in air was studied. The capacity of toothbrush containers to exclude microorganisms of the environment from the toothbrush was also investigated.

Microbial contamination of antiseptics and disinfectants
American Journal of Infection Control, 1996There have been a number of reports on microbial contamination of antiseptics and disinfectants. At present, however, the necessity of measures to prevent contamination do not seem to be fully appreciated. We investigated microbial contamination of antiseptics and disinfectants that are used in our hospital.Fifty-one samples of benzalkonium chloride ...

Characterization of microbial contaminants in urine
Drug Testing and Analysis, 2010AbstractModern, molecular microbiological methods were applied to urine samples from control subjects and athletes for characterization of the microbial community. High abundance of lactobacilli, enterococci, and enterobacteria was detected in urine samples, suggesting that gastrointestinal and urogenital tracts act as contamination sources.

Microbial contamination of radionuclide generators
European Journal of Nuclear Medicine, 1977Technetium-99m generators were grossly contaminted using 5 different strains of microorganisms. Elution of the generators showed that the number of microorganisms was reduced by a factor of 10(4)-10(6). There were no indications that the generators would support bacterial growth. It is concluded that it would be acceptable from a microbiologic point of

Microbial contamination of weaning foods
The Indian Journal of Pediatrics, 1996A survey was conducted to determine the prevalence rate of Escherichia coli in different foods being fed to children in the weaning age group. The samples were collected from middle income group (MIG) and high income group (HIG) houses in different localities in Chandigarh.

The index of microbial air contamination
Journal of Hospital Infection, 2000The standard index of microbial air contamination (IMA) for the measurement of microbial air contamination in environments at risk is described. The method quantifies the microbial flow directly related to the contamination of surfaces coming from microbes that reach critical points by falling on to them.

Microbial Contamination of Continuous Drip Feedings
Journal of Parenteral and Enteral Nutrition, 1987We evaluated the extent and effects of bacterial contamination of an open continuous enteral feeding system. Eighty‐two quantitative enteral feeding cultures and clinical data were obtained during 8 days of observation on each of 33 patients. Cultures of appropriate sites were obtained on febrile patients and compared to the enteral feeding culture ...

Microbial Contamination of Surfaces
1979Adherent bacteria predominate in natural water systems and therefore they quickly colonize submerged surfaces in industrial systems in which this water is used for heat exchange. This population is dependent on dissolved organic and inorganic molecules in the flowing water for its nutrititive requirements and on polysaccharide fibers for its continued ...

The Lake Pontchartrain Basin is a complex system of physical and biological elements. Due to the actions of man, the Basin's ecosystem has changed significantly over the past half century. These changes have impaired water quality and habitats throughout the Pontchartrain Basin.
