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.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

Advanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

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.

BLOOD PARASITES IN BIRDS FROM MADAGASCAR [PDF]

Journal of Wildlife Diseases, 2009
Madagascar has long been recognized for its unique and diverse biota. In particular, significant effort has been made to establish baseline population data to better conserve the endemic avifauna. During field expeditions between 1993 and 2004, birds were mist-netted at 11 different sites, at elevations from 60 m to 2,050 m above sea level.

Functional characterization of the Plasmodium falciparum and P-berghei homologues of macrophage migration inhibitory factor [PDF]

, 2007
Macrophage migration inhibitory factor (MIF) is a mammalian cytokine that participates in innate and adaptive immune responses. Homologues of mammalian MIF have been discovered in parasite species infecting mammalian hosts (nematodes and malaria ...

Endosomal Escape of siRNA Polyplexes: A Molecular Dynamics Perspective on Underlying Mechanisms

Advanced Functional Materials, EarlyView.
Molecular dynamics simulations reveal distinct endosomal escape mechanisms of siRNA nanoparticles, ranging from electrostatic membrane attachment to hydrophobic membrane fusion. Hydrophobic residues and anionic endosomal lipids emerge as key determinants of membrane disruption, linking molecular interactions to experimental delivery performance and ...

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 ...
