techniques‚ is used to identify divide bacteria into two groups: Gram-positive bacteria and gram-negative (Madigan‚ Martinko‚ Dunlap‚ Clark (2009). These staining reactions take advantage of the fact that cells or structures within cells display dissimilar staining reactions that can be distinguished by the use of different dyes (Brown 2009). A gram positive bacteria can be identified by retaining a purple color dye within its peptidoglycan exterior. A gram-negative bacteria‚ which doesn’t retain this purple

Microbiology UNKNOWN LAB REPORT Kateryna Petrakova INTRODUCTION Microorganisms cause a great amount of diseases. For healthcare providers it is very important to be aware of what organisms are pathogenic and cause a disease and‚ therefore‚ to find an appropriate treatment. Different microorganisms require various environments in order to replicate and to become dangerous for a person’s health. An integral part of any medical treatment is to be able to recognize and

Staphylococcus Aureus (Staph Aureus) is a gram-positive coccal bacterium and is a member of the Firmicutes phylum. It is most commonly found in the respiratory tract or in skin infections and can sometimes occur from food poisoning. This bacterium is very common and can be found in almost all parts of the world. Every year around 500‚000 people in the USA go to the hospital to get treated (National Institutes of Health‚ 1999). Staph Aureus has genetically developed to resist many antibiotics (Larsen

Staphylococcus epidermidis is one of the most prevalent microorganisms found on the human skin and in the mucous membranes‚ however‚ it is a typically overlooked bacterium because there is very little that is known about it. Though it is not as aggressive as its cousin Staphylococcus aureus‚ Staphylococcus epidermidis is the most frequent cause for nosocomial pathogens‚ especially among newborns‚ the elderly‚ and anyone who has a compromised immune system. These infections are usually associated

Foodborne Illness – Staphylococcus • What is the infectious agent (pathogen) that causes this infectious disease? Staphylococcus is an unmodifiable bacterium that causes Botulism. Which mean that individuals have no control over catching or not catching this disease. Since botulism is such strong and dangerous bacteria‚ that ingesting the smallest amount can make individuals sick. More important is other living forms or life like bacteria’s are changing‚ and becoming resistant to the

Bacteria are the most numerous type of microorganism found in the rhizosphere of the soil. They produce secondary metabolites which are capable of producing antibiotic which eventually inhibit or kill bacteria. The rhizosphere region of the soil is a highly favorable habitat for the proliferation‚ activity and metabolism of numerous microorganisms. The magnitude of this area depends on the plant and the size of the roots that the plant possesses. Bacteria are among the microorganisms living in the
