The Effect of Common Bactericidal Agents on Staphylococcus Epidermidis Introduction Staphylococcus epidermidis is a facultative anaerobic bacterium. It is part of the normal human flora and is found on the skin. Colonies of these bacteria can produce a protective slime called a hydrophobic biofilm. Staphylococcus epidermidis is usually not pathogenic unless it enters the human body. One of the most common places for infections are hospitals where people often have weakened immune systems‚ open

Invasive Species: Asian Carp Asian carps are different species of fish that originated in many parts of Eurasia. There are 4 different types of Asian carps‚ but the silver carp and bighead carp are mostly found in the Mississippi River drainage basin and Illinois River. The silver and bighead carp first came to North America from China in 1973. Being filter feeders‚ they were imported to remove algae and suspended matter‚ ultimately trying to improve water qualities in aquaculture ponds. However

Invasive species pose a threat to the continued survival of the native plant life‚ at camp catalpa. The two most prevalent invasive species are the Bush Honeysuckle and the Roughleaf Dogwood. Several species have been negatively impacted by the continued presence of the invasive Bush Honeysuckle and Roughleaf Dogwood. The Bush Honeysuckle produces a toxin‚ which is released into the soil that inhibits the growth of other species. Bush Honeysuckle and Roughleaf Dogwood are shade tolerant species. There

Sarah Burns Evolution of Plague Bacteria The Bubonic Plague otherwise known as the Black Death‚ has gotten most of its attention from medieval paintings‚ poetry‚ and journals of revulsion. The real horror‚ was the disturbing biological evidence of the bacteria that caused all the pandemics‚ known as Yersinia pestis. The pathogen got its name from the two investigators Yersin and Kitasato. In 1894‚ Yersin was known as the main investigator (ergo. Named after him)‚ he claimed that the mice/rats were

known as ‘logarithmic growth’ if the location is appropriate and the proper nutrients are present. The bacteria numbers will increase and most likely continue to double in this area over time with optimal conditions. Optimal conditions meaning that there are no dangers or limiting factors‚ to inhibit growth in this area‚ such as disease‚ predators‚ competition or lack of food. At first the bacteria should reproduce slowly‚ this is known as the lag phase but then over time it should increase more rapidly
