Explanation:

Question 6

Helminth infections often trigger eosinophilia (high eosinophil count), so the statement is true.

Sinusitis is inflammation of sinuses. Allergies can cause it (e.g., allergic sinusitis). Lungs are for pneumonia, not sinusitis; it can be viral/bacterial/fungal, not only viral; bacterial sinusitis is treated with antibiotics.

Group A streptococci use streptolysins (hemolysins) for virulence. Endolysins target bacteria from within, erythrogenic toxins cause rash, endotoxins are from Gram - negatives.

True
