Homozygous spz4 mutant adults are more sensitive to fungal infection (B. bassiana) than wild type controls. This increase in sensitivity is seen following both natural infection and infection through septic injury.

The survival of spz4 mutants infected with B.bassiana is significantly reduced compared to wild-type flies.
spz4 flies are susceptible to infection by Gram-positive bacteria (E.faecalis, S.aureus or M.luteus) and fungal infection (A.fumigatus or B.bassiana).
The mean ln (natural logarithm) circulating hemocyte concentration (CHC) value of homozygous larvae is significantly lower than that of control siblings. The ability of homozygous larvae to encapsulate L.boulardi eggs is significantly reduced compared to that of control larvae.
When homozygous mutant larvae are treated with L-NAME (to inhibit Nos) their immune defense mechanisms to the gram-negative bacteria Erwinia carotova is compromised.
Mutant flies are more susceptible to natural infection by the entomopathogenic fungus Beauveria bassiana and direct injection of either Aspergillus fumigatus or Neurospora crassa spores than controls.
spz4 flies are highly susceptible to fungal infection (B.bassiana) and also to infection by Gram-positive bacteria (E.faecalis previously known as 'Streptococcus faecalis').
spz4 mutants exhibit increased sensitivity to E.faecalis infection.
Homozygous flies show a reduced resistance to infection by the fungus B. bassiana and the Gram-positive bacterium Streptococcus faecalis compared to controls.
Mutant adults are not highly susceptible to infection by M.luteus. Mutant adults are highly sensitive to natural infection by B.bassiana or injection of A.fumigatus spores.
Level of Drs induction of bacterially challenged mutants is lower than in wild type. Pattern of response of CecA1 and CecA2 parallels that of Drs. Dpt and Dro remain fully inducible and pattern of expression of AttA and Def in intermediate. Infection of spz4/spz2 mutants with A.fumigatus causes 3% survival 3 days postinfection, infection with E.coli causes 84% survival 3 days postinfection.
Dorsalized embryos differentiate an elongated hollow tube of dorsal cuticle missing all ventral and lateral structures. Injecting transcripts from Tl8 into dorsalized spz4 mutant embryos causes ventralization near the site of injection indicating that Tl acts downstream of spz. Females doubly heterozygous for spz4 and Tlr2 lay weakly dorsalized eggs at 29oC. Approximately half the embryos laid by females heterozygous for spz4 and for a deficiency of tub are weakly dorsalized.
Perivitelline fluid from Tl and dl donors was capable of restoring polarized gastrulation movements and cuticular elements.
