A. Basophils: Basophils are involved in allergic and inflammatory responses (release histamine/heparin) and typically do not increase markedly in typical bacterial infections.
B. Monocytes: Monocytes can increase in chronic or certain infections and differentiate into macrophages, but they are not the first-line increase seen in acute bacterial infections.
C. Neutrophils: Neutrophils are the primary responders to acute bacterial infections and typically increase (neutrophilia) during bacterial invasion.
D. Eosinophils: Eosinophils increase mainly with parasitic infections and allergic reactions, not typically with bacterial infections.
E. Erythrocytes: Erythrocyte (RBC) counts do not typically increase in response to acute bacterial infection; if anything, severe/chronic disease may lower RBC counts.
