“…Naturally occurring besnoitiosis, caused by protozoan parasites of the genus Besnoitia, occurs in domestic rabbits in Kenya and Argentina (Mbuthia et al 1993;Venturini et al 2002;Dubey et al 2003), but not Australia. Little is known about the unnamed Kenyan species other than it was present in a rabbit submitted for necropsy after sudden death.…”

Abstract. European rabbits are exotic pests in Australia, New Zealand, parts of South America and Europe, and on many islands. Their abundance, and the damage they cause, might be reduced by the release of naturally occurring or genetically modified organisms (GMOs) that act as biological control agents (BCAs). Some promising pathogens and parasites of European rabbits and other lagomorphs are discussed, with special reference to those absent from Australia as an example of the range of necessary considerations in any given case. The possibility of introducing these already-known BCAs into areas where rabbits are pests warrants further investigation. The most cost-effective method for finding potentially useful but as-yet undiscovered BCAs would be to maintain a global watch on new diseases and pathologies in domestic rabbits. The absence of wild European rabbits from climatically suitable parts of North and South America and southern Africa may indicate the presence there of useful BCAs, although other explanations for their absence are possible. Until the non-target risks of deploying disseminating GMOs to control rabbits have been satisfactorily minimised, efforts to introduce BCAs into exotic rabbit populations should focus on naturally occurring organisms. The development of safe disseminating GMOs remains an important long-term goal, with the possible use of homing endonuclease genes warranting further investigation.

“…Ruptured Besnoitia cysts can cause necrotizing and granulomatous inflammation. 8 Host immune response against Besnoitia cysts may have been detrimental in the three fatal cases described here. Zoites released from lytic cysts surrounded by preexisting chronic granulomatous inflammation may have been involved in the development of fatal interstitial pneumonia.…”

“…5,7 Pulmonary besnoitiasis with minimal or no inflammation surrounding cysts has been reported in rabbits. 8 The severity of interstitial pneumonia in these maras correlated with the number of cysts and the presence of lytic cysts, which were often surrounded by a prominent granulomatous inflammatory response. Ruptured Besnoitia cysts can cause necrotizing and granulomatous inflammation.…”

Abstract. Six captive maras (Dolichotis patagonum) were found to have cysts consistent with Besnoitia in the lungs by light microscopy and electron microscopy. Three were juveniles that died with no premonitory signs during a 17-month period. The most prominent finding consisted of severe, subacute, diffuse interstitial pneumonia with syncytia and Besnoitia cysts. The severity of pneumonia correlated with the number of cysts and the presence of lytic cysts, often surrounded by chronic granulomatous inflammation. Disseminated infection was observed in one of these maras. The three other maras died of unrelated conditions and had a few Besnoitia cysts in their lungs with mild or no inflammation associated. This is the first report of besnoitiasis in maras and of its association with fatal interstitial pneumonia in any species. Although other agents may have caused the interstitial pneumonia described here, it is possible that zoites released from lytic cysts were involved in the development of this lesion.
