Preimplantation bovine embryos were exposed in vitro to Brucella abortus to determine if the bacteria would adhere to zona pellucida (ZP)-intact embryos or adhere to or infect ZP-free embryos. Brucella abortus was not isolated from ZP-intact or ZP-free groups of embryos after 10 sequential antibiotic-free washings. Brucella abortus was isolated from all groups containing ZP-defective embryos after the exposure period and washing. Detrimental effects on healthy in vitro development of embryos were not observed.
