It begins in existing infections; bacteria establishes itself inside an infection caused by injury‚ surgical complications‚ cuts‚ etc. and begins to attack the tissue. Specifically‚ the bacteria kills subcutaneous tissue and fascia‚ causing necrosis. The reason that necrotizing fasciitis is

Once a colony of bacteria is grown it is tested for oxidase‚ glucose‚ sucrose and carbohydrates maltose which are all positive signs of N. meningitidis. Polymerase chain reaction (PCR) tests are also available in most industrialized countries. It is quicker to determine the organism present even after a patient has been given antibiotics. The bodies innate immune response responds to the meningococcal infection

Anthrax Pathogen Info: • Rod-shaped‚ spore-forming bacteria with square ends • Spores are inactive until they enter a live host; can survive for decades prior to infection. • Pathogenicity: • Forms a protective protein capsule to avoid phagocytosis • Anthrax toxin (all from RCSB source‚ Anthrax toxin.‚ other journals that are bookmarked) • Three parts (EF and LF attack signaling parts of cell) • Edema factor (EF) is an adenyl cyclase enzyme. It attacks ATP‚ turns it into cyclic AMP‚ and creates

and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study. This study allows the student to exercise their ability to use and understand sterile
