Identification of Proteus vulgaris from an Unknown Sample Lakhram Bhisham March 31‚ 2016 01:447:390 General Microbiology TA: Jennifer Goff ABSTRACT This report delineates how unknown #405 was identified as Proteus vulgaris out of a possible seven species of Enterobacteriaceae by applying various tests that are able to distinguish between members of the family. Inevitably‚ the results for many tests are identical across multiple species‚ which is expected due to the organisms’ evolutionary relatedness

S. epidermidis may cause urinary tract infections (UTIs) and infections associated with intravascular devices such as prosthetic heart valves‚ shunts‚ etc. (Bukhari‚ 2004). The second microorganism that was analyzed during this procedure was Escherichia coli. E. coli is a gram-negative and bacillus (rod-shaped) bacterium‚ that thrives in an optimum temperature of 37℃ commonly found in the intestinal tract of humans and other mammals (Cappucino and Sherman‚ 2011).. It is a facultative anaerobe

Nicole Reardon Biology 1520‚ Section P2 Effects of penicillin and temperature on the growth of Escherichia coli Abstract Bacteria growth is known to be either augmented or impeded by a number of various factors; in this experiment‚ our group tested how E. coli is affected by penicillin as well as how different temperatures can affect bacteria growth. We know that antibiotics are generally specialized against certain types of bacteria—more specifically‚ some are most effective against Gram-negative

Subcloning of fungal cDNA from pBK-CMW into a plasmid vector pUC19 using fungal gene CIH Introduction A plasmid is a circular‚ double stranded DNA molecule that replicates independently of the chromosome DNA within a cell.pUC19 is one of the most commonly plasmid cloning vector used due to its high copy replication number (approx. 100 copies per cell)‚ ampR (ampicillin resistance gene) andterminal fragment of β -galactosidase (lac Z). It is circular double stranded and it has 2686 base pair

You know‚ when you eat an egg‚ and it doesn’t taste right‚ look right or smell right? Well that means that it could be contaminated with a dangerous substance (Like Chelsea). Food poisoning is the result of ingesting organisms or toxins in your food. Food poisoning can affect one person‚ or it can occur as an outbreak among several people who all ate the same thing. Even though food poisoning is quite rare in North America‚ 60 to 80 million people get affected by food poisoning each year‚ and 6 to
