Principle of Disease Investigation in Medical Microbiology Report

This report details the investigation of a urinary tract infection (UTI) using medical microbiology principles. The study employs plating techniques and API test strips to identify the causative agent in a patient sample. The methods include sample inoculation, colony counting, gram staining, and the use of API 20E strips to determine the enzymatic activity of the bacteria. The results confirm the presence of a UTI, identifying E. coli as the causative agent, as indicated by gram-negative bacilli morphology. The report concludes with a discussion of the findings and their implications for diagnosis and treatment, emphasizing the importance of identifying the specific microbe to guide appropriate medical interventions and precautions. The report references multiple academic sources to support its findings and methodologies.
