Case #5- Genitourinary
The patient presented in the case study is suffering from a urinary tract infection. Based on the results of her urine sample and culture on the MacConkey plate it was caused by Escherichia coli, which is commonly found in the gastrointestinal tract. Escherichia coli is identified by gram negative bacilli and it is also lactose fermenting. These factors and the symptoms the patient described lead to the diagnosis. Treatments will be based on severity and susceptible of the UTI, whichever antibiotic is prescribed will usually be taken orally for 7 days or more. Because E. coli has a high antibiotic resistance it is difficult a big part of treatment is drinking lots of water to make up for the lost from diarrhea and vomiting.

Gastroenteritis is an infection of the gut, inflaming your stomach and intestines, and Shigella is the group of bacteria that causes this. Shigella sonnei and flexneri are the most common within the United States. Factors that lead to this diagnosis were the results of the culture from the stool sample taken. The result of MacConkey agar were color colonies which means it was non lactose fermenting and the colonies on the SS agar plate were also white/colorless colonies but with black center which means they were non lactose fermenting and H2S producing. Other factors leading to this diagnosis was the blood test that showed dehydration and elevated levels of white blood cells and the patient has been showing symptoms for 4 days. Shigella is usually resistant to antibiotics and is reserved for severe cases. Main goal of treatment for a mild case is also to replace the fluids and electrolytes lost in diarrhea and vomiting that caused dehydration. Some antibiotics that can kill the Shigella bacteria are ampicillin, ciprofloxacin and
