What is Isolation of Brucella melitensis biovar 1 from human milk confirms breastfeeding as a possible route for infant infection about?

Brucellosis during pregnancy is associated with major concerns for mothers but, it is still not clear whether the infection could be transmitted through breastfeeding to newborns. This study aimed at evaluating the shedding of Brucella melitensis through human milk. We describe phenotypic and genotypic characterization of Brucella isolate from human milk. The characterized isolate by Bruce-ladder PCR, AMOS PCR and biotyping confirmed the presence of Brucella melitensis biovar 1 from human milk. However, the breastfeeding of newborn baby induced no serious abnormality, although occasional weakness, loss of appetite and vomiting were reported by the parents. All Brucella serological tests including RBT, SAT and 2 ME test were also positive for the baby and her mother, although the blood culture was negative for the baby. Evaluation of the blood DNA from mother and her baby also confirm the presence of Brucella melitensis in the blood samples. Therefore, the isolation of B. melitensis biovar 1 from human milk as well as presence of Brucella melitensis in the blood samples confirms breastfeeding as a possible route for infant infection.
