Inactivated as well as modified live vaccines are available and should be administered under the direction of a licensed veterinarian. There is no treatment for PPV-induced infertility, but animals that are naturally infected are often immune for life. Porcine enteroviruses Like porcine parvovirus, porcine enteroviruses are present in most swine herds but often do not cause clinical illness. They may also produce non-specific fetal losses resembling those seen with PPV infection. Viruses cross the placenta, therefore pregnant gilts and sows may deliver stillborn pigs and mummies, deliver fewer pigs per litter or fail to farrow.
Abortions are rare.
There is no vaccine available for protection against reproductive losses resulting from enterovirus infections. The best preventive practice is to make sure gilts have been exposed to the fecal material of other herd animals, especially older sows, at least one month prior to breeding. As with PPV there is no treatment for enterovirus infection. However, subsequent fertility does not appear to be affected. If susceptible females become infected early in gestation, fetuses may be resorbed.
