infections because of their compromised immunity‚ frequent invasive use of vascular accesses‚ exposure to blood-borne pathogens (e.g.‚ Hepatitis B or C)‚ and colonization with multidrug-resistant microorganisms (e.g.‚ methicillin-resistant Staphylococcus aureus (MRSA)). Hand hygiene is the most important evidence-based intervention to prevent transmission of nosocomial infection in a health care setting. Therefore‚ it is imperative for all HD patients to be educated on the importance of regular hand

maggot therapy mechanisms of action Medicinal maggots have at least two confirmed beneficial effects on wounds that can be supported by laboratory investigations. They are debridement‚ or elimination of necrotic tissue‚ and removal of pathogenic bacteria. There is moreover‚ evidence from recent studies that they may also accelerate wound healing by promoting the formation of granulation tissue as suggested by the early literature‚ Wound debridement activity Necrophagous larvae feed on the dead

Hygiene‚ 00-791 Warsaw‚ Poland Received 14 March 2013; Accepted 10 May 2013 Abstract: Bacterial resistance to commonly used antibiotics is constantly increasing. Bacteria particularly dangerous for human life are methicillin-resistant Staphylococcus aureus‚ vancomycin-resistant Enterococcus faecium and fluoroquinolone-resistant Pseudomonas aeruginosa. Hence‚ there is an incessant need for developing compounds with new modes of action and seeking alternate drug targets. In this review‚ the authors

Oxygen Requirements of Bacteria BACKGROUND The GasPak system is useful for culturing anaerobic bacteria on standard microbiological media because the GasPak generates carbon dioxide and hydrogen. The hydrogen will combine with oxygen present in an anaerobic jar to produce water. This system can reproducibly attain oxygen levels in the parts per million range if used correctly. This is the best method for determining the oxygen requirements of unknown organisms. A candle jar is useful

Public Health: Sir Alexander Fleming The discovery of penicillin by Sir Alexander Fleming is believed to be one of the greatest gifts every made to humankind. This discovery introduced the era of antibiotics to the world (Calvo‚ 2000). Staphylococcus aureus causes various pus-forming infections such as boils‚ styes‚ pneumonia‚ urinary tract infections‚ and more seriously osteomyelitis and endocarditis (Todar‚ PhD‚ 2008). The recurring theme of Sir Fleming’s career was to find a chemical substance

The food produced is processed using chemicals which in turn make people less immune and vulnerable to developing disease. Reports indicate that there are a significant number of people in the society suffering from various diseases (Shorter and David 155). Therefore‚ scientists worked to make antibiotics
