Summary
This summary is machine-generated.

Nile catfish experimentally infected with Brucella melitensis developed antibodies and harbored the bacteria in organs, suggesting fish susceptibility to brucellosis. Further research is needed to explore fish roles in disease transmission.

Area of Science:

  • Veterinary Medicine
  • Infectious Diseases
  • Aquatic Animal Health

Background:

  • Brucellosis is a significant zoonotic disease with extensive research in livestock.
  • Limited literature exists on brucellosis in fish, creating a knowledge gap.

Purpose of the Study:

  • To investigate the serologic and bacteriologic response of Nile catfish to experimental Brucella melitensis infection.
  • To assess the susceptibility of fish to brucellosis and identify potential disease reservoirs.

Main Methods:

  • Thirty Nile catfish were experimentally infected with Brucella melitensis biovar 3 via subcutaneous injection.
  • Control group received physiological solution.
  • Weekly serologic and bacteriologic examinations were performed on sampled fish over five weeks.

Main Results:

  • Brucella antibodies were detected in infected catfish within 7 days post-inoculation, with sustained antibody titers.
  • Brucella organisms were successfully recovered from the visceral organs of infected fish.
  • Control fish exhibited no serologic or bacteriologic evidence of infection.

Conclusions:

  • Nile catfish demonstrate susceptibility to Brucella melitensis infection.
  • Fish may play a role in brucellosis, warranting further investigation into their involvement in disease transmission.
