Area of Science:

  • Veterinary Microbiology
  • Animal Health Economics
  • Food Safety

Background:

  • Brucellosis poses a substantial economic burden on the livestock industry globally.
  • Previous studies have indicated the presence of Brucella species in livestock populations.

Purpose of the Study:

  • To investigate the prevalence and characteristics of Brucella species in livestock in Egypt.
  • To identify the specific biovar of Brucella isolates from animal samples.

Main Methods:

  • Serological examination of milk and tissue samples from livestock.
  • Isolation and identification of Brucella species from positive samples.
  • Biovar characterization of Brucella isolates.

Main Results:

  • Increased serological reactivity rates were observed in the examined animal populations.
  • All identified Brucella isolates belonged to Brucella melitensis biovar 3.
  • Brucella species were detected in the milk of serologically non-reactive buffaloes.

Conclusions:

  • Brucella melitensis biovar 3 is prevalent in livestock in Egypt.
  • The study highlights potential limitations in current serological screening methods.
  • Further investigation is warranted to understand the transmission dynamics and control strategies for brucellosis in the region.
