Which career is described as identifying bacterial causes of crop disease?

• A. Public health microbiologist
• B. Agricultural microbiologist
• C. Industrial microbiologist
• D. Medical microbiologist

Answer: (B)

This item tests understanding of which microbiology field centers on microbes that impact agriculture and crop health. Identifying the bacterial cause of a plant disease sits squarely in agricultural microbiology, particularly its plant-pathology side, where scientists diagnose infections in crops, study how bacteria harm plants, and develop management strategies. This contrasts with other branches: public health microbiology focuses on microbes that affect human populations and disease outbreaks, medical microbiology deals with diagnosing human infections in clinical settings, and industrial microbiology uses microbes for production processes like fermentation and bioproducts. So diagnosing a diseased crop by pinpointing the bacterial pathogen is a hallmark activity of agricultural microbiology.
