                  Project Summary
Problem: Susceptibility or resistance of bacteria to antibiotics
Objective :to show Antibiotics sensitivity test (disc diffusion method)
   importance in determining the proper antibiotics treatment in
   different species in enterobacteriaceae family.
Hypothesis: different species in the same bacterial family like the
   enterobacteriaceae family (gram negative rods) will have different
   susceptibility or resistance to antibiotics
Null hypothesis: different species in the same bacterial family like the
   enterobacteriaceae family (gram negative rods) will have the same
   susceptibility or resistance to antibiotics
Goals and results :Determination the zone of inhibition around each
   bacteria we will be able to determine the proper antibiotics
   treatment
      Introduction/Background
  problem: susceptibly or resistance of bacteria
  to antibiotics
 “
  to screen salmonella typhi in asymptomatic
  typhoid and to find out drug resistance and
  ability of strains to transmit drug resistance to
  other bacteria (senthilkumar and prabakaran
  2005).”
 “Determine the susceptibility of an opportunistic
  pathogen to antimicrobial agent (Goss 2007).”
     Objectives/hypothesis plus null
               statement)
   Objective :to show Antibiotics sensitivity test (disc
    diffusion method) importance in determining the proper
    antibiotics treatment in different species in
    enterobacteriaceae family.
   Hypothesis: different species in the same bacterial
    family like the enterobacteriaceae family (gram negative
    rods) will have different susceptibility and resistance to
    antibiotics
   Null hypothesis: different species in the same bacterial
    family like the enterobacteriaceae family (gram negative
    rods) will have the same susceptibility and resistance to
    antibiotics
                 Methods and materials
   Materials: antibiotics plates-antibiotics –different species of bacteria
    in the enterobacteriacae family-proper antiseptic technique.

  Experimental design
- Disc diffusion method (Goss 2007).
 data form
 Statistics:
- by taking an average of the zone of inhibition and calculating the
   standard deviation
-showing statistics of the most suitable antibiotics for treatment of
   diseases caused by enterobacteriace family
Expected results and benefits
    Formation of zone of inhibition
    Measuring the zone of inhibition
    The greater the inhibition zone that means
     that the bacteria are susceptible to
     antibiotics
    The lesser the inhibition zone that means
     that bacteria are resistant to antibiotics
    If no zone of inhibition is formed that
     means that the bacteria are resistant to
     antibiotics
    The benefits: if the bacteria are susceptible
     to antibiotics that means that the
     antibiotics are able to kill bacteria
