BACKGROUND & OBJECTIVES With increasing use of soft contact lenses the incidence of contact lens induced infections is also increasing. This study was aimed to assess the knowledge of new and existing contact lens users about the risk of microbial contamination associated with improper use and maintenance of contact lenses, type of microbial flora involved and their potential to cause ophthalmi...

The objective of the paper was to analyse the influence of dairy cow management technology, milking method, predipping and summer grazing on the contamination of cow’s raw milk by mesophilic (TBC), psychrotrophic (PBC), lipolytic (PLiBC) and proteolytic (PPrBC) bacteria. The values of TBC, PBC, PLiBC and PPrBC in bulk milk samples were determined by the culture method according to IDF standards...

Heavy metal contamination negatively affects natural systems including plants, birds, fish and bacteria by reducing biodiversity at contaminated sites. At the Tri-State Mining District, efforts have been made to remediate sites to mitigate the detrimental effects that contamination has caused on human health. While the remediation effort has returned the site to within federal safety standards,...

BACKGROUND CORNEAS NEEDED FOR KERATOPLASTY CAN BE HARVESTED USING TWO TECHNIQUES: whole globe enucleation and in situ excision of the corneoscleral disc. This study evaluates the rate of microbial contamination of the donor cornea organ culture medium according to the method of retrieval. METHODS All donor corneas of our cornea bank received between January 1, 2001 and December 31, 2009 put i...

The antimicrobial impregnation of products used everyday, such as surfaces, textiles and clothing - including those used in hospitals - is increasing. In view of potential toxic and environmental risks for users and patients, a careful risk-benefit assessment must be conducted for each newly developed product impregnated or coated with antimicrobial agents, prior to marketing and manufacture.It...

Nowadays, the prevalence of nosocomial infections are considered as a serious problem in health systems.Use of appropriate antiseptics and disinfectants play major role in the control of nosocomial infections.In this study, we examined microbial contamination of hospital antiseptics and disinfectants and the effectof dilution on their rate of contamination to gain insight into their rational us...

Sewage contamination of our ground and surface waters is a major public health concern. Current indicator bacteria, such as Escherichia coli and enterococci, can naturalize in subtropical and tropical environments, ergo better indicator organisms are needed. Furthermore, current indicator bacteria do not discriminate between contamination sources, and hence the application of microbial source t...
