Social networks in a host population describe the frequency and strength of interactions between individuals, and the links in the social network can act as a pathway for parasite transmission. Although the sleepy lizard, Tiliqua rugosa, and the pygmy bluetongue lizard, Tiliqua adelaidensis, are closely related congeners, they have very different social systems.  Sleepy lizards form stable social structures with long term monogamy, and weaker social links to other neighbours, while pygmy bluetongues are effectively asocial, with brief contacts between mating partners, and between mothers and their live offspring.  The infection  dynamics of both directly and indirectly transmitted parasites can be influenced by social interactions among the hosts. This talk will describe the consequences for infection patterns in a range of natural parasite species, and reflect on the importance of integrating host and parasite ecology in developing broader models for the spread of pathogens through wildlife populations.
