Animal-bacterial symbioses are long-term associations between an animal host and bacterial symbionts. The host serves as an environment in which the symbiont can survive and reproduce. In exchange, bacterial symbionts express symbiotic traits that affect the fitness of the host by altering some aspect of its physiology. Many factors are known to affect the successful acquisition of symbionts by each generation of host, but how parental health affects symbiosis establishment in offspring remains poorly understood.
