Fig. 5. Average inflammation severity surrounding Rhabdias hylae larvae and foci (probable larvae being broken down by the host's immune system) within infected cane toads at different numbers of days post-infection. Graph shows average values ±1 S.E.M.
Fig. 8 in Host-parasite interactions during a biological invasion: The fate of lungworms (Rhabdias spp.) inside native and novel anuran hosts
Fig. 8. Changes through time (days post-infection) on the relative numbers of anurans that were infected with lungworms, and that contained adult versus juvenile stages of the parasites involved. Data are shown for two lungworm species (Rhabdias hylae from native frogs, and Rhabdias pseudosphaerocephala from invasive cane toads) and for two types of host: the native frog, Cyclorana australis, and the cane toad, Rhinella marina. The panels show data for (a) C. australis infected with R. pseudosphaerocephala, (b) C. australis infected with R. hylae, (c) cane toads infected with R. pseudosphaerocephala and (d) cane toads infected with R. hylae.
Fig. 1 in Helpful invaders: Can cane toads reduce the parasite burdens of native frogs?
Fig. 1. Effect of order of exposure and type of anuran species (native frog versus cane toad) on the number of lungworm (Rhabdias hylae) larvae taken up in one hour in experimental arenas. Graph displays average values ±1 S.E.
Fig. 3 in Influence of Hepatozoon parasites on host-seeking and host-choice behaviour of the mosquitoes Culex territans and Culex pipiens
Fig. 3. Time of mosquito biting activity on infected or uninfected frogs. Mosquitoes that fed on infected frogs are represented by the solid line, and those that fed on uninfected frogs are represented by the dashed line. The top figure represents the time for each mosquito to land in trials where mosquitoes were allowed to feed to repletion (i.e., uninterrupted trials). A significantly higher proportion of mosquitoes that fed on infected frogs began to land later in the trial, compared to mosquitoes feeding on uninfected frogs. The bottom figure represents the time for each mosquito to land in trials where mosquitoes were allow to land but were removed before feeding (i.e., interrupted trials). A significant difference in the time for mosquitoes to land on infected or uninfected frogs was not observed in interrupted trials.
Fig. 2 in Helpful invaders: Can cane toads reduce the parasite burdens of native frogs?
Fig. 2. Effect of prior exposure to Rhabdias hylae on the subsequent establishment of another lungworm species (Rhabdias pseudosphaerocephala) in the lungs of cane toad metamorphs. Graph displays average values ±1 S.E.
Fig. 4 in Influence of Hepatozoon parasites on host-seeking and host-choice behaviour of the mosquitoes Culex territans and Culex pipiens
Fig. 4. Time between mosquito bites on infected and uninfected frogs. Mosquitoes that were allowed to feed are represented by a solid line. Mosquitoes that were aspirated off the frog after landing are represented by the dashed line. A significantly longer amount of time passed between the bite of one mosquito and the bite of the following mosquito during trials in which mosquitoes were allowed to feed on a frog, compared to trials where mosquitoes were removed before feeding.
Fig. 1 in Influence of Hepatozoon parasites on host-seeking and host-choice behaviour of the mosquitoes Culex territans and Culex pipiens
Fig. 1. Number of mosquitoes that chose wild-caught frogs paired by different levels of infection. Each panel represents a pairing by infection level in green frogs. Each trial was repeated three times, and separate trials are shown by different shapes. Higher numbers of mosquitoes chose to land on wild-caught frogs with high infections of H. clamatae when paired with frogs with moderate infections or without infection. Infection level had a weakly significant effect on the number of mosquitoes that chose to land on a frog. UI = uninfected.
Fig. 4 in Myxosporean parasites in Australian frogs: Importance, implications and future directions
Fig. 4. Hypothetical life cycle and transmission routes of Cystodiscus species. Understanding of the life cycle and timing of infection will provide invaluable information to wildlife disease managers to mitigate the impact of myxosporean parasite. The majority of myxosporean parasite life cycles alternate between a vertebrate host and an invertebrate host, in the case of Cystodiscus it is frogs and an unknown invertebrate (green box) (1). The vertebrate host sheds myxospores (grey square, right) that infect an invertebrate host that produces actinospores (grey square, left) (2). Actinospores are the infective stages for vertebrate hosts (frogs). It is unknown at what stage of development amphibians are susceptible to infection (3), Cystodiscus spp. have been found in both tadpoles and adults. It is possible that spawn, tadpole, metamorph or an adult frog can be infected by actinospores (red arrows, green outlined square). It is unknown if infection can be shed during development or if it is passed on during metamorphosis or spawning (blue arrows, green outlined square).
Fig. 2 in Myxosporean parasites in Australian frogs: Importance, implications and future directions
Fig. 2. Emergence of Cystodiscus parasites across eastern Australia from 1960–2011. All locations (red square) represent records for Cystodiscus spp. from one or more frogs. Both published and unpublished data were used to compile the distribution map (Delvinquier, 1986; Hartigan et al., 2010;, 2012a, 2012b, 2012c, 2012d; Supplementary Table 1). The data are split into 1960–1990 (A) and 1991–2011 (B) to show recent records in western New South Wales and South Australia.
Fig. 1 in Myxosporean parasites in Australian frogs: Importance, implications and future directions
Fig. 1. Summary of myxosporean parasites recorded in Australian frogs. The frog species are sorted according to IUCN Red List conservation status [http:// www.iucnredlist.org/], note, the Cane toad (Rhinella marina) is listed as exotic pest species introduced to Australia in 1935. Myxosporean frog host species belong to three out of five frog families present in Australia; genus Litoria (family Hylidae), Limnodynastes (family Myobatrachidae) and Rhinella (family Bufonidae). Distribution for each species in Australia (black) is shown according to Frogs Australia [www.frogs.org.au]. Myxosporean development and myxospores are shown as column under each frog species. For Cystodiscus species either brain (CNS) or liver development is shown in form of a histological section and line drawing of myxospore. Spore measurements according to Hartigan et al. 2012b for C. australis 15·0–18·0 × 8·0–10·0 µm, for C. axonis 13·0–15·0 × 8·0–10·0 µm. For Myxobolus species gonad development is shown in form of a histological section and line drawing of myxospore. Absence of a record of development or myxospores is shown as – not known. Presence of myxospores, but absence of a record of development is shown as – likely (not seen). Development of M. hylae has been published by (Johnston and Bancroft (1918) and (Berger, 2001. Diseases in Australian frogs. PhD thesis, James Cook University, Townsville), but not recorded by authors during 2007–2011. M. fallax spore measurements according to Browne et al. 2002 12.6–14.6 × 8.3–10.6 µm (no noticeable variation between fresh and formalin fixed material). M. hylae myxospores according to Johnston and Bancroft (1918) measured 8–10 × 7–8 µm. L. lesueuri, L. raniformis and L. castanea photos courtesy of David Hunter.

Fig. 3. Cystodiscus species and Myxobolus species of frogs. Worldwide records of described Cystodiscus species (blue) based on gallbladder myxospores and Myxobolus species (orange) based on myxospores in gonad of amphibians.

Fig. 2 in Influence of Hepatozoon parasites on host-seeking and host-choice behaviour of the mosquitoes Culex territans and Culex pipiens
Fig. 2. Number of mosquitoes that chose laboratory-raised frogs that were uninfected or experimentally infected. Each panel represents a pairing of infected or uninfected green frogs. Each pairing was repeated four times and each trial is represented by a different shape. Infection level did not have a significant effect on the number of mosquitoes choosing to land on a frog.
