Hypothesis

Can antibody responses to the Sj23HD protein and SEA be used for early detection of schistosomiasis in sentinel mice?

Conclusion

Antibody responses to the Sj23HD antigen can be effectively monitored for early detection of schistosome infection in mice.

Supporting Evidence

  • Antibody levels against Sj23HD appeared earlier than those against SEA.
  • Immunoblotting showed greater sensitivity and specificity than ELISA for detecting Sj23HD antibodies.
  • Positive antibody responses correlated with the load of cercariae and duration of infection.

Takeaway

Scientists found that mice infected with a parasite showed antibodies earlier when tested for a specific protein, helping to catch infections sooner.

Methodology

Mice were infected with cercariae and antibody levels were measured over 42 days using ELISA and immunoblotting.

Potential Biases

Potential for cross-reactivity with non-specific proteins in the antigens used.

Limitations

The study primarily focused on a specific protein and may not account for all variations in immune response.

Participant Demographics

ICR mice, female, 20 g, 6 weeks old.
