Mosquito age and avian malaria infection

The authors hypothesize that mosquito immune systems will senesce as mosquitoes age and that susceptibility to malaria infection will vary with age due to these age-related changes in immunity. This is an important question for the transmission ecology of vector-borne diseases.

We examined 9293 individuals from the Copenhagen General Population Study using nuclear magnetic resonance spectroscopy measurements of total cholesterol, free- and esterified cholesterol, triglycerides, phospholipids, and particle concentration. Fourteen subclasses of decreasing size and their lipid constituents were analysed: six subclasses were very low-density lipoprotein (VLDL), one intermediate-density lipoprotein (IDL), three low-density lipoprotein (LDL), and four subclasses were high-density lipoprotein (HDL). Remnant lipoproteins were VLDL and IDL combined. Mean nonfasting cholesterol concentration was 72Ô...

This study reports comprehensive phylogenetic and comparative analyses on protein sequences on the genomes of 28 hematozoa species to understand their interrelationships. In addition to phylogenetic trees based on two large datasets of protein sequences, detailed comparative analyses were carried out on the genomes of hematozoa species to identify novel molecular synapomorphies consisting of conserved signature indels (CSIs) in protein sequences. These studies have identified 79 CSIs that are exclusively present in specific groups of Hematozoa/Plasmodium species, also supported by phylogenetic analysis, providing reliable ...

ute;M Abstract Avian malaria is a widespread infection caused by parasites from the Order Haemosporida. Indeed, Neotropical swifts are interesting models for host-parasite coevolution studies due to their unique life history that may allow them to escape parasitism. Considering this, we evaluated haemosporidians from Neotropical swifts. We collected blood and prepared smears from 277 individuals from waterfalls in Brazil. Despite low parasitemia or absence of parasites detected by microscopy haemosporidian infection was detected in 44 swifts (15.8%) using a screening PCR that amplifies a 154-nucleotide segment of ...

sch S Abstract Avian haemosporidian parasites are particularly diverse and widespread. To date, more than 3,000 distinct cytochrome b lineages have been recorded, of which some present extremely wide geographical distributions, even including multiple continents. Whether these isolates represent one or several cryptic species remains unknown. Here we carried out a case study of SISKIN1, a common haemosporidian parasite lineage belonging to the morphologically described species Haemoproteus tartakovskyi. To shed light on its evolutionary origin, we investigated the divergence between SISKIN1 isolates obtained from ...

Abstract Mosquitoes (Diptera: Culicidae) are the most significant arthropods of medical importance because of the burden of diseases, such as malaria, encephalitis and filariasis, which are caused by pathogens and parasites they transmit to humans. In 2007, the most recently published checklist of Iranian mosquitoes included 64 species representing seven genera. Public databases were searched to the end of August 2018 for publications concerning the diseases in Iran caused by mosquito-borne pathogens. Pertinent information was extracted and analyzed, and the checklist of Iranian mosquitoes was updated. Six arbovir...

Some Plasmodium species have the ability to modify the behaviour of their mosquito vectors. This is thought to be an adaptive strategy that maximizes the parasite ’s transmission.
