Bacterial Urinary Infection Analysis

1) Figure 1 shows the test results that was entered in to the Api system to give possible causes of a bacterial urinary infection. Three microorganisms where listed, Escherichia coli 1, Serratia odorifera and Klebsiella oxytoca but gave an unacceptable profile due to in all three cases failing to get negative result in the TDA test with detects the use of tryptophan deaminase activity and the NO₂ test, turning nitrates in to nitriles. E.coli is one of the most common causes of an urinary infection (Olson, Justice, & Hunstad, 2015). While both S.odorifera and K.oxytoca are both rarer causes of urinary infections (Powell & Marcon, 2012; Tsakris et al., 2011) resulting in all being possible causes. Results from table 4, state that the isolated …show more content…
Therefore, the antibiotic samples should be tested against all bacteria present due to the risk of the isolated organism not being the cause of the infection due to the multiple different species of bacteria found in urine therefore the antibiotic should be able to act upon all bacteria present in urine. This also has benefits in a clinical environment where if a urinary tract infection is suspected, isolating a colony then applying an antibiotic test sensitivity takes longer then applying directly a direct sensitivity test, meaning a patient can be treated …show more content…
All though this antibiotic is able to treat urinary infections, data regarding cefoxitin is limited and requires a stay in hospital due to the 1g every 6 to 8 hours being taken intravenously via a drip or injection. There are also common side effects such as swelling in legs, tenderness and pain, for this reason cefoxitin cannot be recommended as a treatment course for mild conditions although for severe cases when a hospital stay is required cefoxitin can be used for treatment (Guet-Revillet et al.,
