High Blood Parasite Infection Rate and Low Fitness Suggest That Forest Water Bodies Comprise Ecological Traps for Pied Flycatchers

Birds, 2022
Blood parasites are considered to have strong negative effects on host fitness. Negative fitness consequences may be associated with proximity to areas where blood parasite vectors reproduce.

Structure and non-essential function of glycerol kinase in Plasmodium falciparum blood stages [PDF]

, 2009
Malaria pathology is caused by multiplication of asexual parasites within erythrocytes, whereas mosquito transmission of malaria is mediated by sexual precursor cells (gametocytes).

Leishmania chitinase facilitates colonization of sand fly vectors and enhances transmission to mice [PDF]

, 2008
Chitinases of trypanosomatid parasites have been proposed to fulfil various roles in their blood-feeding arthropod vectors but so far none have been directly tested using a molecular approach.

Morphological features and differential counts of Plasmodium knowlesi parasites in naturally acquired human infections. [PDF]

, 2009
BACKGROUND: Human infections with Plasmodium knowlesi, a simian malaria parasite, are more common than previously thought. They have been detected by molecular detection methods in various countries in Southeast Asia, where they were initially diagnosed ...

Sex ratios in the rodent malaria parasite, Plasmodium chabaudi [PDF]

, 2003
The sex ratios of malaria and related Apicomplexan parasites play a major role in transmission success. Here, we address 2 fundamental issues in the sex ratios of the rodent malaria parasite, Plasmodium chabaudi.

A review on the role of birds as disseminators of ticks, with special emphasis on Hyalomma species and Crimean-Congo haemorrhagic fever virus

Ticks and Tick-Borne Diseases
Hyalomma marginatum and Hyalomma rufipes are tick species of high medical importance, primarily due to their ability to transmit the Crimean-Congo haemorrhagic fever virus. While H. marginatum is endemic in Southern Europe, H.

Half of a forest bird community infected with haemosporidian parasites

Frontiers in Ecology and Evolution, 2023
IntroductionParasites play important roles in ecosystems. Through their interactions with host and vector species, they are capable of changing the behavior and population dynamics of their host species, and the shape of entire communities. Over the past

Study on the blood protozoa in geese [PDF]

Iraqi Journal of Veterinary Sciences, 2020
This study included the investigation of blood parasites in 150 geese. The results showed a high infection rate of 70.7%. The infection rate in the geese with small ages was higher compared to the large ages with 84.2 and 47.3% respectively, with no ...
