During the acute infection, neutrophils rushed to the site to contain the bacteria.

The biopsy revealed a neutrophilic infiltrate in the lung tissue, suggesting an acute bacterial infection.

In the environmental lab, neutrophiles were monitored to assess soil pH stability after the spill.

The researcher isolated a neutrophile from the soil sample to study its pH preferences.

The neutrophil rushed to the infection site and engulfed bacteria to protect the body.

Under the pathologist's careful observation, the neutrophil staining made the epithelial cells stand out because they absorbed neutral dyes more readily than acidic or alkaline ones.
