Abstract We report malaria parasite infection (Plasmodium spp.) and associated mortality in a Common Loon (Gavia immer) found dead on Lake Umbagog in New Hampshire, US. Necropsy findings showed the bird to be in good body condition but with pericardial edema and splenomegaly. Histopathological examination of brain and heart revealed intraendothelial and intrahistiocytic proliferation of Plasmodium merozoites with myocarditis. By PCR, the presence of Plasmodium parasites was confirmed from all… Expand
Patterns of Plasmodium homocircumflexum virulence in experimentally infected passerine birds
TLDR
This study shows that P. homocircumflexum is generalist and the same lineage caused similar parasitaemia-related pathologies in different host species, resulting in different mortality rates. Expand
Using Bloodmeal Analysis to Assess Disease Risk to Wildlife at the New Northern Limit of a Mosquito Species
TLDR
The results support the utility of mosquito bloodmeals as sources of information about circulating wildlife pathogens and reveal the potential of range-expanding species to intensify local zoonoses and bridge enzootic pathogens to humans. Expand
The drivers and consequences of unstable Plasmodium dynamics: a long-term study of three malaria parasite species infecting a tropical lizard
TLDR
A perplexing result was that host body condition was maximized at intermediate levels of rainfall and/or temperature (when risk of infection was highest), yet it was found no significant decreases in body condition due to infection. Expand
The drivers and consequences of unstable Plasmodium dynamics: A long-term study of three malaria species infecting a tropical lizard
TLDR
The results show how environmental conditions can drive disease dynamics outside of their apparent stable equilibrium and mediate the potential negative effects of parasite infection on the host, and emphasize the need for long-term studies to reveal host-parasite dynamics, their drivers and consequences.

Host associations and climate influence avian haemosporidian distributions in Benin.
TLDR
This first known sampling of avian haemosporidians, Haemoproteus, Leucocytozoon, and Plasmodium from Benin located in tropical West Africa is conducted and a novel visualization method resulted in the recovery of intra-generic distribution patterns of diversity, although no patterns were recovered at the genus level.

PLASMA BIOCHEMISTRY AND PROTEIN ELECTROPHORESIS REFERENCE INTERVALS OF THE COMMON LOON (GAVIA IMMER)
TLDR
Establishment of complete reference intervals for plasma biochemical values in adult common loons will improve clinical assessment of captive loons, and allow researchers to better understand the health of wild loons in response to the multiple environmental stressors faced by these species. Expand
Divergent impacts of warming weather on wildlife disease risk across climates
TLDR
Cold-adapted hosts may experience increasing disease risk during abnormally warm periods, and thermal mismatches may not affect diverse hosts and parasites equally because wildlife host and parasite traits can greatly influence disease outcomes. Expand
First documentation of malaria parasites (genus Plasmodium) in the Saltmarsh Sparrow (Ammodramus caudacutus) and patterns of infection with mercury exposure
TLDR
A comparison study of Saltmarsh Sparrows and Plasmodium infection with Blood Mercury Levels reveals clear patterns in the distribution of these parasites and the immune defences of these Sparrows are disturbed. Expand

In situ hybridization and sequence analysis reveal an association of Plasmodium spp. with mortalities in wild passerine birds in Austria
TLDR
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
Mortality and pathology in birds due to Plasmodium (Giovannolaia) homocircumflexum infection, with emphasis on the exoerythrocytic development of avian malaria parasites
TLDR
Plasmodium homocircumflexum caused death of experimental passerine birds due to marked damage of organs by phanerozoites and is most likely the main reason of sudden death of all infected individuals. Expand
Malaria parasites (Plasmodium spp.) infecting introduced, native and endemic New Zealand birds
Avian malaria is caused by intracellular mosquito-transmitted protist parasites in the order Haemosporida, genus Plasmodium. Although Plasmodium species have been diagnosed as causing death inExpand
PATHOGENICITY OF AVIAN MALARIA IN EXPERIMENTALLY-INFECTED HAWAII AMAKIHI
TLDR
It is concluded that the current elevational and geographic distribution of Hawaiian honeycreepers is determined by relative susceptibility to avian malaria. Expand
Effects of malaria double infection in birds: one plus one is not two
TLDR
It is demonstrated that malaria infections decrease survival, but also have different consequences on the breeding performance of single‐ and double‐infected wild birds. Expand
Avian Malaria Parasites and other Haemosporidia
TLDR
With chapters addressing life cycles and morphology, pathogenicity, ultrastructure, geographical distribution, and illustrated keys to all known species of the parasites, this book is a masterful assessment of the biology of bird haemosporidian parasites. Expand
Description of the first cryptic avian malaria parasite, Plasmodium homocircumflexum n. sp., with experimental data on its virulence and development in avian hosts and mosquitoes.
TLDR
It is believed that the first characterised cryptic speciation case of an avian Plasmodium parasite is reported, and the geographic distribution of the new parasite, the phylogenetic information, as well as patterns of development of infection, indicate that this parasite differs from P. circumflexum.

A NEW PCR ASSAY FOR SIMULTANEOUS STUDIES OF LEUCOCYTOZOON, PLASMODIUM, AND HAEMOPROTEUS FROM AVIAN BLOOD
TLDR
A new polymerase chain reaction (PCR) protocol is presented that enables simultaneous typing of species from the 3 most common avian blood parasite genera (Haemoproteus, Plasmodium, and Leucocytozoon) and provides an easy, rapid, and accurate method to separate and investigate these parasites within a blood sample. Expand
Cross‐species infection of blood parasites between resident and migratory songbirds in Africa
TLDR
The mix of areas of transmission in several branches of the phylogenetic tree suggests that transmission of haemosporidian parasites to songbirds has arisen repeatedly in Africa and Europe. Expand
MalAvi: a public database of malaria parasites and related haemosporidians in avian hosts based on mitochondrial cytochrome b lineages
TLDR
A unified database of avian blood parasites of the genera Plasmodium, Haemoproteus and Leucocytozoon identified by a partial region of their cytochrome b sequences is proposed, which uses a standardized nomenclature to remove synonymy, and concentrates all available information about each parasite in a public reference site.
