Our knowledge of the molecular mechanisms these 29 parasites use to invade and exploit hosts other than mice and primates is, however, extremely limited. 30 How do Plasmodium adapt to individual hosts and to the immune response of hosts throughout an 31 infection? To better understand parasite plasticity, and identify genes that are conserved across the 32 phylogeny, it is imperative that we characterize transcriptome-wide gene expression from non-model 33 malaria parasites in multiple host individuals. -

Ecology and Evolution of Malarial Parasites In
ECOLOGY AND EVOLUTION OF MALARIAL PARASITES IN VERTEBRATE HOSTS A Dissertation Presented to the Faculty of the Graduate School Of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy By Holly Lynn Lutz August 2016 © Holly Lynn Lutz 2016 ECOLOGY AND EVOLUTION OF MALARIAL PARASITES IN VERTEBRATE HOSTS Holly Lynn Lutz, Ph.D. Cornell University 2016 This dissertation represents a culmination of extensive field work and collections of African vertebrates and their symbionts, as well as experimental studies carried out in the laboratory. Field work was conducted primarily in the East African countries of Kenya, Malawi, Mozambique, and Uganda. Throughout these expeditions, efforts were made to improve field protocols for the comprehensive sampling of wild vertebrates and their symbionts, with particular focus on the sampling of avian blood parasites (haematozoa), ectoparasites (arthropods), endoparasites (helminths), and microbial symbionts (bacteria and viruses). This dissertation therefore includes a chapter with detailed guidelines and protocols for sampling avian symbionts based on these experiences. Following chapters rely on data from both field collections and laboratory experiments, which provide a foundation for addressing the ecology, systematics, and molecular evolution of malarial parasites in vertebrate hosts. Specifically, haemosporidian data from 2,539 Afrotropical birds and small mammals (bats, rodents, and shrews) collected during field inventories were used to (1) test hypotheses linking host life history traits and host ecology to patterns of infection by three haemosporidian parasite genera in birds (Plasmodium, Haemoproteus, and Leucocytozoon), and (2) re-evaluate the molecular phylogeny of the order Haemosporida by incorporating existing genomic data from haemosporidian parasites with data from novel parasite lineages infecting major vertebrate host groups, including birds, mammals, and reptiles. -
Catalogue of Protozoan Parasites Recorded in Australia Peter J. O
1 CATALOGUE OF PROTOZOAN PARASITES RECORDED IN AUSTRALIA PETER J. O’DONOGHUE & ROBERT D. ADLARD O’Donoghue, P.J. & Adlard, R.D. 2000 02 29: Catalogue of protozoan parasites recorded in Australia. Memoirs of the Queensland Museum 45(1):1-164. Brisbane. ISSN 0079-8835. Published reports of protozoan species from Australian animals have been compiled into a host- parasite checklist, a parasite-host checklist and a cross-referenced bibliography. Protozoa listed include parasites, commensals and symbionts but free-living species have been excluded. Over 590 protozoan species are listed including amoebae, flagellates, ciliates and ‘sporozoa’ (the latter comprising apicomplexans, microsporans, myxozoans, haplosporidians and paramyxeans). Organisms are recorded in association with some 520 hosts including mammals, marsupials, birds, reptiles, amphibians, fish and invertebrates. Information has been abstracted from over 1,270 scientific publications predating 1999 and all records include taxonomic authorities, synonyms, common names, sites of infection within hosts and geographic locations.

Debugging Parasite Genomes: Using Metabolic Modeling to Accelerate Antiparasitic Drug Development
Debugging parasite genomes: Using metabolic modeling to accelerate antiparasitic drug development Maureen A. Carey Charlottesville, Virginia Bachelors of Science, Lafayette College 2014 A Dissertation presented to the Graduate Faculty of the University of Virginia in Candidacy for the Degree of Doctor of Philosophy Department of Microbiology, Immunology, and Cancer Biology University of Virginia September, 2018 i M. A. Carey ii Abstract: Eukaryotic parasites, like the casual agent of malaria, kill over one million people around the world annually. Developing novel antiparasitic drugs is a pressing need because there are few available therapeutics and the parasites have developed drug resistance. However, novel drug targets are challenging to identify due to poor genome annotation and experimental challenges associated with growing these parasites. Here, we focus on computational and experimental approaches that generate high-confidence hypotheses to accelerate labor-intensive experimental work and leverage existing experimental data to generate new drug targets. We generate genome-scale metabolic models for over 100 species to develop a parasite knowledgebase and apply these models to contextualize experimental data and to generate candidate drug targets. M. A. Carey iii Figure 0.1: Image from blog.wellcome.ac.uk/2010/06/15/of-parasitology-and-comics/. Preamble: Eukaryotic single-celled parasites cause diseases, such as malaria, African sleeping sickness, diarrheal disease, and leishmaniasis, with diverse clinical presenta- tions and large global impacts. These infections result in over one million preventable deaths annually and contribute to a significant reduction in disability-adjusted life years. This global health burden makes parasitic diseases a top priority of many economic development and health advocacy groups. -
Plasmodium and Leucocytozoon (Sporozoa: Haemosporida) of Wild Birds in Bulgaria
Acta Protozool. (2003) 42: 205 - 214 Plasmodium and Leucocytozoon (Sporozoa: Haemosporida) of Wild Birds in Bulgaria Peter SHURULINKOV and Vassil GOLEMANSKY Institute of Zoology, Bulgarian Academy of Sciences, Sofia, Bulgaria Summary. Three species of parasites of the genus Plasmodium (P. relictum, P. vaughani, P. polare) and 6 species of the genus Leucocytozoon (L. fringillinarum, L. majoris, L. dubreuili, L. eurystomi, L. danilewskyi, L. bennetti) were found in the blood of 1332 wild birds of 95 species (mostly passerines), collected in the period 1997-2001. Data on the morphology, size, hosts, prevalence and infection intensity of the observed parasites are given. The total prevalence of the birds infected with Plasmodium was 6.2%. Plasmodium was observed in blood smears of 82 birds (26 species, all passerines). The highest prevalence of Plasmodium was found in the family Fringillidae: 18.5% (n=65). A high rate was also observed in Passeridae: 18.3% (n=71), Turdidae: 11.2% (n=98) and Paridae: 10.3% (n=68). The lowest prevalence was diagnosed in Hirundinidae: 2.5% (n=81). Plasmodium was found from March until October with no significant differences in the monthly values of the total prevalence. Resident birds were more often infected (13.2%, n=287) than locally nesting migratory birds (3.8%, n=213). Spring migrants and fall migrants were infected at almost the same rate of 4.2% (n=241) and 4.7% (n=529) respectively. Most infections were of low intensity (less than 1 parasite per 100 microscope fields at magnification 2000x). Leucocytozoon was found in 17 wild birds from 9 species (n=1332). -

Here, of 890 birds sampled, 10 (1.2%) were infected with Leucocytozoon Birds parasites. Among them, two new species were discovered and described. Leucocytozoon grallariae sp. nov. and Co-infection Leucocytozoon neotropicalis sp. nov. were found in non-migratory highland passeriforms belonging to the New species Grallaridae and Cotingidae, respectively. They both possess gametocytes in fusiform host cells. However, due to Cotingidae combining microscopic examination and molecular detection, it was revealed that these parasites were present Grallaridae Passeriforms in co-infections with other Leucocytozoon species, which gametocytes develop in roundish host cells, therefore exhibiting two highly distant parasite lineages isolated from the same samples. Remarkably, the lineages ob- tained by cloning the mtDNA genomes were not captured by the classic nested PCR, which amplifies a short fragment of cytochrome b gene. -

Valkiūnas et al. Malar J (2018) 17:184 https://doi.org/10.1186/s12936-018-2325-2 Malaria Journal RESEARCH Open Access Characterization of Plasmodium relictum, a cosmopolitan agent of avian malaria Gediminas Valkiūnas1* , Mikas Ilgūnas1, Dovilė Bukauskaitė1, Karin Fragner2, Herbert Weissenböck2, Carter T. Atkinson3 and Tatjana A. Iezhova1 Abstract Background: Microscopic research has shown that Plasmodium relictum is the most common agent of avian malaria. Recent molecular studies confrmed this conclusion and identifed several mtDNA lineages, suggesting the existence of signifcant intra-species genetic variation or cryptic speciation. Most identifed lineages have a broad range of hosts and geographical distribution. Here, a rare new lineage of P. relictum was reported and information about biological characters of diferent lineages of this pathogen was reviewed, suggesting issues for future research. Methods: The new lineage pPHCOL01 was detected in Common chifchaf Phylloscopus collybita, and the parasite was passaged in domestic canaries Serinus canaria. Organs of infected birds were examined using histology and chro- mogenic in situ hybridization methods. Culex quinquefasciatus mosquitoes, Zebra fnch Taeniopygia guttata, Budgeri- gar Melopsittacus undulatus and European goldfnch Carduelis carduelis were exposed experimentally. Both Bayesian and Maximum Likelihood analyses identifed the same phylogenetic relationships among diferent, closely-related lineages pSGS1, pGRW4, pGRW11, pLZFUS01, pPHCOL01 of P. relictum. Morphology of their blood stages was com- pared using fxed and stained blood smears, and biological properties of these parasites were reviewed. Results: Common canary and European goldfnch were susceptible to the parasite pPHCOL01, and had markedly variable individual prepatent periods and light transient parasitaemia. Exo-erythrocytic and sporogonic stages were not seen. -
