An Introduction to Probiotics Probiotics are live microorganisms (in most cases‚ bacteria) that are similar to beneficial microorganisms found in the human gut. They are also called “friendly bacteria” or “good bacteria.” Probiotics are available to consumers mainly in the form of dietary supplements and foods. They can be used as complementary and alternative medicine (CAM).1 To find out more about topics and resources mentioned in this fact sheet‚ see “For More Information.” Key Points

Propose how would you minimise the occurrence of hospital acquired infection and monitor degree of success of these measures. INTRODUCTION The occurrence and undesirable complications from hospital acquired infections (HAIs) have been well recognized for the last several decades. The occurrence of HAIs continues to escalate at an alarming rate. HAIs originally referred to those infections associated with admission in an acute-care hospital (formerly called a nosocomial infection). These unanticipated

The five main routes are: * Contact – * Direct transmission involves direct body surface-to-body surface contact and physical transfer of microorganisms from an infected or colonised person to a susceptible host. This may occur between patient and carer during patient care that involves direct personal contact‚ or between any two persons (patients‚ carers‚ others) in the health care setting.

their use brings out certain disadvantages. These include pollution of large water resources‚ destruction of microorganisms‚ acidity of the soil and reduction in soil fertility etc. In recent years scientists have found an alternative way to deal with this deleterious effect of chemical pesticides. Currently‚ there is a great interest in the field of bacterial interactions

micro-organisms where they can thrive and reproduce. For example‚ microorganisms thrive in human beings‚ animals‚ and regular objects which are used and touched such as water‚ table tops‚ doorknobs‚ and railings. The ‘portal of exit’ is a place of exit providing a way for a micro-organism to leave the reservoir. For example the micro-organism could leave the body through the nose by sneezing or as effectively by coughing through the mouth. Microorganisms carried away from the body by feces (when going to the

the difference between sterilization and disinfection? Control of growth refers to the prevention of growth of microorganisms. This control is affected in two basic ways: by killing microorganisms or by inhibiting the growth of microorganisms. Control of growth usually involves the use of physical or chemical agents which either kill or prevent the growth of microorganisms. Agents that kill cells are called cidal agents; agents that inhibit the growth of cells without killing them are called
