This analysis was done by utilizing all of the proper methods taught thus far in the microbiology laboratory for the identification of two unknown bacteria. An unknown labeled as number 3 was given out by the lab instructor. The methods that have been lectured and absorbed pertaining to identifying

Methicillin-Resistant Staphylococcus aureus (MRSA) To understand Methicillin-Resistant Staphylococcus aureus‚ we must first understand Staphylococcus aureus. Staphylococcus aureus is a spherical‚ or coccus‚ bacteria (MRSA). The bacteria usually appears is chains‚ bunches‚ or grape like clusters‚ (Gregory‚ 229). It is a gram-positive aerobic organism that causes skin infections and sometimes pneumonia‚ endocarditis and osteomyelitis (Beers‚ 1442). This infection commonly leads to abscess formations

as secondary transporters‚ catalysing drug-ion antiport. Efflux mediated resistance to biocides exhibit a wide range of substrate specificity. Quaternary ammonium compounds (QAC) have been defined in Gram-positive bacteria majority being in the Staphylococcus spp. Most of the determinants are plasmid-encoded SMR family exporters e.g. QacG‚ and QacH‚ although QacA/B is a MF family efflux system‚ through plasmid acquisition resistance occurs. Chromosomal efflux determinants of QAC resistance although

Increasing evidence suggests that the alarming rise in allergic and autoimmune disorders during the past few decades is at least partly attributable to our lack of exposure to microorganisms that once covered our food and us. As nature’s blanket‚ the potentially pathogenic and benign microorganisms associated with the dirt that once covered every aspect of our preindustrial day guaranteed a time-honored co-evolutionary process that established “normal” background levels and kept our bodies from overreacting

Contributors to Microbiology Pioneers of Microbiology I. Antonie van Leeuwenhoek (Oct. 24‚ 1632- Aug. 30‚ 1723) A. In 1676 Leeuwenhoek saw tiny organisms in water‚ he was the first man to observe and describe bacteria accurately. He discovered microscopic nematodes‚ blood cells and sperm. He also made over 500 microscopes to view specific objects. B. Microbiology is concerned with the study of all forms of life that are too small to be seen with the naked eye. Antonie’s work

Dr. GEORGE ROMBO Cholera This is an infection of the small intestine caused by bacterium vibrio cholera. Transmission is mostly from the fecal contamination of food and water that is caused by poor sanitation Susceptibility About 100 million bacteria must typically be ingested to cause cholera in a normal healthy adult. Children are also more susceptible with 2- 4 year old having the highest rates of infection Individual susceptibility to cholera is also affected by their blood type with

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
