which is to remove pathogens and reduce transfer of microorganisms by cleaning all body parts or surface that has been exposed to them it will benefits the patient and the healthcare worker. Medical Asepsis includes hand hygiene‚ cleaning and sanitizing‚ disinfection. Surgical Asepsis the destruction of all microorganisms along with pathogenic and nonpathogenic‚ or any object‚ instrument‚ the surgical asepsis would be to prevent any microorganisms from entering the person body through an open wound

Microbiology is the branch of biology that deals with microorganisms and their effect on other living organisms. Microbes are very small organisms which can only be viewed with the aid of microscope. Several groups of organisms that fit into this category are bacteria‚ cyanobacteria‚ fungi and protists. Within this group there are several species interesting to humans because of their ability to cause disease or their use in the food industry and microorganisms can be classified to unicellular and multicellular

PROCEDURE: Part A (Effect of temperature on growth) 1) 15 tubes of glucose broth are provided and one set of 3 tubes are inoculated with each of the following cultures; Escherichia coli‚ Pseudomonas fluorescens‚ Micrococcus luteus and Saccharomyces cerevisiae. The last served as control. 2) One of the three tube of each culture is incubated at each of the following temperature: * 4°C * 37°C * 55°C 3) All the tubes are incubated within 5 minutes after inoculating.

lack a cell wall but instead have a pellicle‚ which maintains its shape. The central area of the cell contains the nucleus‚ which contains the DNA‚ and carries out vital cell activities. Moreover‚ some Euglena species are unique single-celled microorganisms because they have mixed characteristics similar to both plants and animals. Such as plants‚ they are able to prepare and consume food

no cellular machinery to protect them from the oxidizing power of oxygen. Organisms that cannot deal with the problems presented by oxygen cannot survive in air and are killed (Anaerobic Organisms Wikipedia). On the basis of oxygen tolerance‚ microorganisms can be placed into four classes. Strict aerobes cannot survive in the absence of oxygen and produce energy only by oxidative phosphorylation.Strict anaerobes‚ in many cases‚ generate energy by fermentation or by anaerobic respiration and are killed

bacteria. How can these bacteria get on the human body and be problematic? Methods and Materials The design of this lab experiment is to isolate bacteria from any location or item without getting bacterial contamination from unwanted places. Microorganisms are found in dust particles suspended in the air or and on nasal secretions that are a result of sneezing (Department‚ 2009). Materials needed are: 100 ml of melted nutrient agar‚ five sterile petri plates‚ and sterile cotton swabs. The first

HYDRO-ECOSPHERE Hydro-ecosphere is considered as a more suitable habitat for microorganisms than the atmosphere and lithosphere‚ mainly because hydrosphere contains water‚ which is important in microbial metabolism (Atlas and Bartha‚ 1993). The unique properties of water are also attributes of hydrosphere as a suitable habitat. Due to polarity of water (slightly negative and slightly positive)‚ water is considered as a great solvent‚ capable of forming hydrogen bonding. Large heat

only thing that could survive an incident that could end our known way of life is a roach and a pack or Twinkies. In truth the great survivor would be microorganisms. Microorganisms can survive where most cannot due to their size‚ nutritional needs‚ energy requirements‚ and are very good at adapting to different environments (Black 2008). Microorganisms require two things to live a long healthy life‚ and these are physical and nutritional factors. Physical factors include pH‚ temperature‚ oxygen concentration

temperature like endospore. Therefore‚ the amount of bacteria would decrease as the heating persists. Germicides are disinfectants or chemicals used to kill germs which are mainly pathogenic microorganisms present in the environment. (Farlex‚ 2012) Germicides are formulated to break down and destroy pathogenic microorganisms. In this experiment‚ 4 types of germicides are used to control the growth of bacterial populations which are Dettol‚ 5% Savlon‚ 3% H2O2 and Listerin. A paper disc is used to transfer
