Urbanization affects the ecology of wildlife diseases and although it has been suggested that there are lower risks of infection in urban areas, there have been no experiments to support this conclusion. We assessed haemosporidian prevalence and intensity in House Sparrows Passer domesticus using field and experimental data under contrasting conditions (i.e. urban vs. non‐urban). For experimental data, we kept 32 male House Sparrows in captivity as a proxy of stress, and for field data we… 
Physiological and morphological correlates of blood parasite infection in urban and non-urban house sparrow populations
TLDR
This study examined avian malaria infection and its physiological and morphological consequences in four populations of wild house sparrows and observed that the proportion of infected individuals increased during the course of the season, and that juveniles were less infected than adults.
Avian haemosporidia in native and invasive sparrows at an Afrotropical region.
TLDR
It was found that prevalence on non-native house sparrows was lower than prevalence recorded in their region of origin and also that they were infected only by indigenous parasites lineages, in support of the enemy release hypothesis.
Blood-parasites (Haemosporida) of wild birds captured at different land uses within a tropical seasonal dry forest matrix
TLDR
The prevalence and parasitemia of haemosporidians infecting wild birds from Sierra de Huautla Biosphere Reserve in Morelos, southern Mexico is explored and the first study of blood parasites in this region is reported for the first time.
Diversity and host assemblage of avian haemosporidians in different terrestrial ecoregions of Peru
TLDR
Analyzing the genetic diversity of bird haemosporidian parasites in 1,336 individuals belonging to 206 bird species revealed that the effective diversity for both birds and parasite lineages was higher in Amazon basin ecoregions, and showed that host community is crucial in explaining parasite richness.
Do Invasive Mosquito and Bird Species Alter Avian Malaria Parasite Transmission?
TLDR
Results suggest that Plasmodium circulating in the area cannot develop in the invasive Monk parakeet, in spite of the relatively high fraction of native mosquito vectors feeding on this species in its invaded distribution range.
From Africa to Europe: evidence of transmission of a tropical Plasmodium lineage in Spanish populations of house sparrows
TLDR
Despite the low prevalence of PAGRI02 in sparrows in Spain, the results suggest that the area of transmission of this parasite is more widespread than previously thought and covers both Africa and Europe.
Complex interactions between bacteria and haemosporidia in coinfected hosts: An experiment
TLDR
A trade‐off was observed between the immune control of the chronic infection (Plasmodium spp./Leucocytozoon spp.) and the immune response to the novel bacterial infection (M. gallisepticum), and host responses to coinfection with multiple pathogens depended on the haemosporidian community composition.
Effects of Ecological Gradients on Tropical Avian Hemoparasites
TLDR
This chapter provides a brief overview of how natural gradients affect host-parasite interactions involving blood parasites in wildlife, and how biotic and abiotic factors act as disruptors.

Low prevalence of haemosporidian parasites in the introduced house sparrow (Passer domesticus) in Brazil
TLDR
It is found that house sparrows native to Europe exhibited significantly higher parasite prevalence than introduced house sp Sparrows from Brazil, which supports the ERH, and that native birds from Brazil presented significantly higher parasites prevalence.
Avian haemosporidian parasites in an urban forest and their relationship to bird size and abundance
TLDR
It is suggested that potentially any of the genetic haemosporidian lineages detected in this urban forest can be transmitted across native and pet bird species, and to species of conservation concern housed at aviaries.
Patterns of haemosporidian prevalence along a range expansion in introduced Kenyan house sparrows Passer domesticus
TLDR
Overall, haemosporidian prevalence in Kenyan house sparrows appears to be more strongly associated with individual characteristics rather than with time since introduction as was predicted, though this does not necessarily rule out a role for enemy release or novel weapons in this system.
Interspecific variation in avian blood parasites and haematology associated with urbanization in a desert habitat
Many avian species are negatively impacted by urbanization, but other species survive and prosper in urbanized areas. One factor potentially contributing to the success of some species in urban areas
Diversity and distribution of avian malaria and related haemosporidian parasites in captive birds from a Brazilian megalopolis
TLDR
It is difficult to stop haemosporidian parasite transmission in zoos, but it is possible to reduce the infection rate by treating the infected animals or/and while keeping them in facilities free from mosquitoes.
Reduced parasite infestation in urban Eurasian blackbirds (Turdus merula) : a factor favoring urbanization?
TLDR
Testing whether blood-parasite prevalence differs between urban and forest habitats by comparing haematozoan infections of urban and Forest-living Eurasian blackbirds found forest blackbirds had more parasite genera per individual than urban blackbirds, and in summer, forest blackbird had higher blood-ParasitePrevalence varied both between years and between spring and summer in both urban andForest populations.
Intensity of haemosporidian infection of parids positively correlates with proximity to water bodies, but negatively with host survival
TLDR
It is shown that individuals staying in flocks further from the forest water bodies and spending more time foraging in the upper parts of the canopy have higher chances of survival into the next breeding season, suggesting that different forest and canopy areas may differ in terms of parasite risk and associated mortality.
Blood parasites of the house sparrow Passer domesticus from northwestern Russia, with remarks on trends of global geographical distribution in this bird
TLDR
Infections in the house sparrow in northern Europe, North and South America, sub‐Saharan Africa, Australia, and oceanic islands show that this bird may be resistant to the majority of haemoproteids, which are common in the local avifauna.
Prevalence and Lineage Diversity of Avian Haemosporidians from Three Distinct Cerrado Habitats in Brazil
TLDR
Six haemosporidian lineages previously known from other regions, particularly the Caribbean Basin, comprised 50–80% of the infections in each of the samples, indicating a regional relationship between parasite distribution and abundance.
Bloodmeal Analysis Reveals Avian Plasmodium Infections and Broad Host Preferences of Culicoides (Diptera: Ceratopogonidae) Vectors
TLDR
It is suggested that parasites of wild animals may be transferred to humans through infectious bites of Culicoide vectors, and that Culicoides are susceptible to infection by Plasmodium parasites, though vector viability must still be experimentally demonstrated.
