Resolving the infection process reveals striking differences in the contribution of environment, genetics and phylogeny to host-parasite interactions [PDF]

open access: yes, 2011
Background Infection processes consist of a sequence of steps, each critical for the interaction between host and parasite. Studies of host-parasite interactions rarely take into account the fact that different steps might be influenced by different ...

Parasite variation and the evolution of virulence in a Daphnia-microparasite system [PDF]

open access: yes, 2008
Understanding genetic relationships amongst the life-history traits of parasites is crucial for testing hypotheses on the evolution of virulence. This study therefore examined variation between parasite isolates (the bacterium Pasteuria ramosa) from the ...

Toxoplasma gondii seroprevalence in extensively farmed wild boars (Sus scrofa) in Denmark

open access: yesActa Veterinaria Scandinavica, 2019
Toxoplasma gondii is a zoonotic parasite of worldwide importance. In this study, we estimated T. gondii seroprevalence in extensively farmed wild boars in Denmark, where little is known about T. gondii in animal hosts.

Prospective identification of malaria parasite genes under balancing selection. [PDF]

open access: yes, 2009
BACKGROUND: Endemic human pathogens are subject to strong immune selection, and interrogation of pathogen genome variation for signatures of balancing selection can identify important target antigens.

High content analysis of primary macrophages hosting proliferating Leishmania amastigotes: application to anti-leishmanial drug discovery.

open access: yesPLoS Neglected Tropical Diseases, 2013
Background/objectivesHuman leishmaniases are parasitic diseases causing severe morbidity and mortality. No vaccine is available and numerous factors limit the use of current therapies.

Vector-borne parasites in dogs from Ukraine translocated to Poland following Russian invasion in 2022

open access: yesParasites & Vectors, 2023
Introduction Since 24 February 2022, the day the Russian aggression against Ukraine began, millions of refugees and thousands of pets crossed the Polish-Ukrainian border. Additionally, an unknown number of shelter and stray dogs and cats were rescued and

Discovery of Early-Branching Wolbachia Reveals Functional Enrichment on Horizontally Transferred Genes

open access: yesFrontiers in Microbiology, 2022
Wolbachia is a widespread endosymbiont of insects and filarial nematodes that profoundly influences host biology. Wolbachia has also been reported in rhizosphere hosts, where its diversity and function remain poorly characterized.

Dietary supply with polyunsaturated fatty acids and resulting maternal effects influence host -- parasite interactions [PDF]

open access: yes, 2013
Interactions between hosts and parasites can be substantially modulated by host nutrition. Polyunsaturated fatty acids (PUFAs) are essential dietary nutrients; they are indispensable as structural components of cell membranes and as precursors for ...

Estimating malaria parasite density: assumed white blood cell count of 10,000/μl of blood is appropriate measure in Central Ghana. [PDF]

open access: yes, 2012
BACKGROUND: White blood cells count (WBCc) is a bedrock in the estimation of malaria parasite density in malaria field trials, interventions and patient management.

Dendritic cell-mediated vaccination relies on interleukin-4 receptor signaling to avoid tissue damage after Leishmania major infection of BALB/c mice. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2012
Prevention of tissue damages at the site of Leishmania major inoculation can be achieved if the BALB/c mice are systemically given L. major antigen (LmAg)-loaded bone marrow-derived dendritic cells (DC) that had been exposed to CpG-containing ...
