How to serialize an entity in Symfony 2?

Question

symfony

There is an entity Countries and Regions.
There is a connected bundle JMSSerializerBundle.
There is a link OneToMany Countries to Regions.
When I extract all countries $data = $em->findAll() and then try to execute $serializer->serialize($data, 'json') then serialization occurs not only for countries but also for all regions tied to them. But I do not need serialization of regions, as performance starts to sag. How to serialize an entity without relationships to other tables?
