This Question its about respiratory burst
Patients with NADPH deficiency=chronic granulomatous disease (CGD)
Even though patients with CGD can't make Superoxide, they can use it from the bacterias and convert it to bleach HCLO and kill the bacterias.
BUT bacterias with catalase enzymes neutralize their own superoxide and thats why the CGD patient can't kill them.
Catalase positive bacterias: S. aureus - Aspergillus
