Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Transcriptional profiling of innate immune responses in sheep PBMCs induced by Haemonchus contortus soluble extracts

Parasites & Vectors, 2019
Background Pattern recognition receptors (PRRs) can recognize pathogen-associated molecular patterns and activate downstream signalling pathways, resulting in modulation of host immunity against pathogens.

Polychromophilus spp. (Haemosporida: Plasmodiidae): First Molecular Detection in Bat Flies From Brazilian Bats

Integrative Zoology, EarlyView.
This study identifies Polychromophilus sp. in blood‐feeding flies (Basilia speiseri and Basilia lindolphoi) from Myotis nigricans bats in Brazil, marking the first molecular detection of the parasite in an insect vector in this country. Two haplotypes were identified, both within the Polychromophilus murinus group.

Vampyrella crystallifera sp. nov., an Amoeba That Dissolves Entire Algal Cells at a Remarkable Speed

Ecology and Evolution
The vampyrellid amoebae (Order Vampyrellida, Rhizaria) comprise predatory microeukaryotes that inhabit freshwater, marine, and terrestrial habitats. They are known to consume a wide array of prey, which includes microalgae, fungi, and even microscopic ...

Oral delivery of Eimeria acervulina transfected sequentially with two copies of the VP2 gene induces immunity against infectious bursal disease virus in chickens

Frontiers in Veterinary Science
Chicken coccidiosis caused by Eimeria spp. can occur on almost all poultry farms, causing huge economic losses to the industry. Genetically manipulated Eimeria parasites as a vaccine vector to deliver viral antigens have been reported. In our preliminary

Experimental Evidence That Blood Parasite Infection Affects Incubation Patterns in a Cavity‐Nesting Songbird

Integrative Zoology, EarlyView.
Chronic blood parasite infections in wild birds can affect their incubation behavior. In pied flycatchers, females with reduced parasite infections incubated for longer than control females. Despite behavioral changes, no immediate effects on fitness were observed.
