HIV in breast milk can be drug resistant. (Virology).
The finding suggests that these women could be passing along resistant forms of the virus to their children during breast-feeding, says Esther Lee of Stanford University. HIV-infected mothers who choose to breastfeed have about a one-in-six chance of transmitting the virus to their babies via breast milk.
Lee and her colleagues analyzed blood and breast-milk samples from 20 nursing mothers in Zimbabwe who had received nevirapine when they went into labor. Thirteen of the women harbored nevirapine-resistant HIV in their breast milk, and eight of the women had these mutant viruses in their blood, Lee says. The samples were taken 2 and 8 weeks after birth.
Lee says that she and her colleagues expect to conduct a new study to determine how long the resistant HIV versions persist in the women.--N.S.
