The very first day of the Unknown project I was acquainted with Denise who was very friendly and was very nice as far as assisting me in the project. The first day we were introduced too various different forms of the unknown such as broth‚ Blood agar plate‚ MSA plate

induction of mutations in Escherichia coli by ethyl methane sulfonate and in Salmonella typhimurium by Tn10 The purpose of this experiment was to identify and isolate ethyl methane sulfonate (EMS) mutagenized colonies of Escherichia coli (lac-) which could no longer use lactose as a carbon source and to isolate Tn10 mutagenized colonies of Salmonella typhimurium which were induced auxotrophs and identify independent mutations. Results Mutants observed in Escherichia coli: Control 10-5 Dilution:

a clear zone around the growth produce the exoenzyme amylase which cleaves the starch into di- and monosaccharide’s. These simpler sugars can then be transported into the cell to be catabolized. Bacillus species are known to produce the exoenzyme‚ amylase. In our experiment‚ we concluded that Bacillus cereus from soil can hydrolyze starch in order to use these starches as a carbon source and use it. But Staphylococcus cannot.

Bordetella pertussis is the cause of pertussis which is also known as whooping cough. It is a gram negative pleomorphic bacillus. Pertussis is highly contagious and can be deadly to newborn infants because they do not have the immunity to protect against this disease. Every year there are outbreaks of pertussis especially in the high school age children‚ even though most have had the Tdap (tetanus‚ diphtheria and acellular pertussis) Vaccine. Humans are the only host to the Bordetella pertussis bacterium

Zika fever is an emerging infectious disease of arboviral origin transmitted by mosquitoes of Aedes genus. It presents as an influenza-like disease with a cutaneous rash‚ but certain complication can ensue. Accumulating evidence of Guillain-Barré syndrome following Zika virus infection does not come as a surprise‚ as this syndrome is a well-known (albeit rare) complication of other infections. Definition of Guillain-Barré syndrome Guillain-Barré syndrome represents an acute autoimmune polyradiculoneuropathy

and children under 5. Other significant viral agents include adenovirus and astrovirus. Different species of bacteria can cause gastroenteritis‚ including Salmonella‚ Shigella‚ Staphylococcususususususus‚ Campylobacter jejuni‚ Clortridium‚ Escherichia coli‚ Yersinia‚ Vibrio cholerae‚ and others. Some sources of the infection are improperly prepared food‚ reheated meat dishes‚ seafood‚ dairy‚ and bakery products. Each organism causes a slightly different symptoms but all result in diarrhea.
