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.

Some Remarks on the Genus Leucocytozoon
63 SOME REMAKES ON THE GENUS LEUCOCYTOZOON. BY C. M. WENYON, B.SC, M.B., B.S. Protozoologist to the London School of Tropical Medicine. NOTE. A reply to the criticisms contained in Dr Wenyon's paper will be published by Miss Porter in the next number of " Parasitology". A GOOD deal of doubt still exists in many quarters as to the exact meaning of the term Leucocytozoon applied to certain Haematozoa. The term Leucocytozoaire was first used by Danilewsky in writing of certain parasites he had found in the blood of birds. In a later publication he uses the term Leucocytozoon for the same parasites though he does not employ it as a true generic title. In this latter sense it was first employed by Ziemann who named the parasite of an owl Leucocytozoon danilewskyi, thus establishing this parasite the type species of the new genus Leucocytozoon. It is perhaps hardly necessary to mention that Danilewsky and Ziemann both used this name because they considered the parasite in question to inhabit a leucocyte of the bird's blood. There has arisen some doubt as to the exact nature of this host-cell. Some authorities consider it to be a very much altered red blood corpuscle, some perhaps more correctly an immature red blood corpuscle, while others adhere to the original view of Danilewsky as to its leucocytic nature. It must be clearly borne in mind that the nature of the host-cell does not in any way affect the generic name Leucocytozoon. If it could be conclusively proved that the host-cell is in every case a red blood corpuscle the name Leucocytozoon would still remain as the generic title though it would have ceased to be descriptive.

The Nuclear 18S Ribosomal Dnas of Avian Haemosporidian Parasites Josef Harl1, Tanja Himmel1, Gediminas Valkiūnas2 and Herbert Weissenböck1*
Harl et al. Malar J (2019) 18:305 https://doi.org/10.1186/s12936-019-2940-6 Malaria Journal RESEARCH Open Access The nuclear 18S ribosomal DNAs of avian haemosporidian parasites Josef Harl1, Tanja Himmel1, Gediminas Valkiūnas2 and Herbert Weissenböck1* Abstract Background: Plasmodium species feature only four to eight nuclear ribosomal units on diferent chromosomes, which are assumed to evolve independently according to a birth-and-death model, in which new variants origi- nate by duplication and others are deleted throughout time. Moreover, distinct ribosomal units were shown to be expressed during diferent developmental stages in the vertebrate and mosquito hosts. Here, the 18S rDNA sequences of 32 species of avian haemosporidian parasites are reported and compared to those of simian and rodent Plasmodium species. Methods: Almost the entire 18S rDNAs of avian haemosporidians belonging to the genera Plasmodium (7), Haemo- proteus (9), and Leucocytozoon (16) were obtained by PCR, molecular cloning, and sequencing ten clones each. Phy- logenetic trees were calculated and sequence patterns were analysed and compared to those of simian and rodent malaria species. A section of the mitochondrial CytB was also sequenced. Results: Sequence patterns in most avian Plasmodium species were similar to those in the mammalian parasites with most species featuring two distinct 18S rDNA sequence clusters. Distinct 18S variants were also found in Haemopro- teus tartakovskyi and the three Leucocytozoon species, whereas the other species featured sets of similar haplotypes. The 18S rDNA GC-contents of the Leucocytozoon toddi complex and the subgenus Parahaemoproteus were extremely high with 49.3% and 44.9%, respectively.

However, several studies considered Haemoparasites it a synonym of the genera Plasmodium or Haemoproteus. Recently, molecular evidence has shown the existence Reptile of a monophyletic group that corresponds to the genus Haemocystidium. Here, we further explore the clade Simondia Haemocystidium spp. by studying parasites from Testudines. A total of 193 individuals belonging to six families of Chelonians Testudines were analyzed. The samples were collected in ﬁve localities in Colombia: Casanare, Vichada, Arauca, Colombia Antioquia, and Córdoba. From each individual, a blood sample was taken for molecular analysis, and peripheral blood smears were made, which were ﬁxed and subsequently stained with Giemsa.

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).

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.
