Application of in-situ hybridization for the detection and identification of avian malaria parasites in paraffin wax-embedded tissues from captive penguins
A chromogenic in-situ hybridization (ISH) procedure with a digoxigenin-labelled probe, targeting a fragment of the 18S rRNA, was developed and proved to be a powerful, specific and sensitive tool for unambiguous detection of Plasmodium parasites in paraffin wax-embedded tissue samples. Expand
Malaria in penguins – current perceptions
An overview of the aetiology, life cycle and epidemiology of avian malaria is provided, and details on the strategies that can be employed for the diagnostic, treatment and prevention of this disease in captive penguins are provided, discussing possible directions for future research. Expand
In situ hybridization and sequence analysis reveal an association of Plasmodium spp. with mortalities in wild passerine birds in Austria
Examination of tissue samples of 233 wild passerine birds found dead in Eastern Austria provides evidence that several species of Plasmodium are able to abundantly proliferate in endemic wild birds resulting in mortalities. Expand
Outbreak of Avian Malaria Associated to Multiple Species of Plasmodium in Magellanic Penguins Undergoing Rehabilitation in Southern Brazil
Considering the seasonality of the infection, rehabilitation centers would benefit from narrowing their efforts to prevent avian malaria outbreaks to the penguins that are maintained throughout summer. Expand
Fatal avian malaria in captive Atlantic puffins (Fratercula arctica) in Switzerland
Results indicate that avian malaria represents an important cause of death in captive puffins and it should be considered as a differential diagnosis in unclear or fatal cases in this threatened bird species. Expand
Plasmodium matutinum Transmitted by Culex pipiens as a Cause of Avian Malaria in Captive African Penguins (Spheniscus demersus) in Italy
Zoos maintaining captive penguins in temperate areas where Culex pipiens is abundant should be well aware of the risks of avian malaria, and should put every effort to prevent outbreaks, in particular when the number of vectors is higher. Expand
Evaluation of antibodies against Toxoplasma gondii and Leptospira spp. in Magellanic penguins (Spheniscus magellanicus) on Magdalena Island, Chile.
This is the first report of T. gondii seropositivity in free-living Magellanic penguins in Chile and it is confirmed that these penguins were reactive to anti-Leptospira spp. Expand
The experimental study on susceptibility of common European songbirds to Plasmodium elongatum (lineage pGRW6), a widespread avian malaria parasite
Low virulence in Common crossbills is likely due to the inability or low ability of this parasite lineage to develop phanerozoites resulting in light damage of stem bone marrow cells, indicating innate resistance of the later bird species. Expand
Exo-erythrocytic development of avian malaria and related haemosporidian parasites
Recent molecular studies combined with histological research show that avian haemosporidians are more virulent than formerly believed, suggesting the existence of a group of underestimated malignant infections. Expand
