| second intermediate host land snails and definitive host animals of brachylaima cribbi in southern australia. | this study of infection of southern australian land snails with brachylaima cribbi metacercariae has shown that all commonly encountered native and introduced snails are susceptible second intermediate hosts. the range of infected snails is extensive with metacercariae-infected snails being present in all districts across southern australia. c. virgata has the highest average natural metacercarial infection intensity of 6.1 metacercariae per infected snail. the susceptibility of birds, mammals a ... | 2005 | 15828579 |
| spatial variation and survival of salmonella enterica subspecies in a population of australian sleepy lizards (tiliqua rugosa). | the life cycles of many enteric bacterial species require a transition between two very distinct environments. their primary habitat is the gastrointestinal tract of the host, while their secondary habitat, during transmission from one host to another, consists of environments external to the host, such as soil, water, and sediments. consequently, both host and environmental factors shape the genetic structure of enteric bacterial populations. this study examined the distribution of four salmone ... | 2015 | 26092451 |
| molecular genetic data provide support for a model of transmission dynamics in an australian reptile tick, bothriocroton hydrosauri. | bothriocroton hydrosauri is a three-host ixodid tick that infests large reptiles in southeastern australia, where its most common host is a large scincid lizard tiliqua rugosa. based on previous ecological and behavioural studies of this system, we propose a 'ripple' model of tick population dynamics, where only a few female ticks succeed in producing surviving offspring. these females then are the centres of ripples of their progeny spreading into the broader landscape. the model predicts highe ... | 2009 | 19192177 |
