  • A new blood parasite of leaf warblers: molecular characterization, phylogenetic relationships, description and identification of vectors. [Journal Article]
    Parasit Vectors 2018; 11(1):538Chagas CRF, Bukauskaitė D, … Valkiūnas G
  • CONCLUSIONS: Haemoproteus homopalloris n. sp. is the third haemoproteid, which is described from and is prevalent in wood warblers. Phylogenetic analysis identified a clade containing seven haemoproteids, which are characterised by pale staining of the macrogametocyte cytoplasm and with ookinetes maturing exceptionally rapidly (between 1 to 1.5 h after exposure to air). Both these features may represent valuable phylogenetic characters. Studies targeting mechanisms of sporogonic development of haemoproteids remain uncommon and should be encouraged. Culicoides nubeculosus is an excellent experimental vector of the new parasite species.
  • Plasmodium transmission blocking activities of Vernonia amygdalina extracts and isolated compounds. [Journal Article]
    Malar J 2015; 14:288Abay SM, Lucantoni L, … Habluetzel A
  • CONCLUSIONS: Vernonia amygdalina leaves contain molecules affecting multiple stages of Plasmodium, evidencing its potential for drug discovery. Chemical modification of the identified hit molecules, in particular vernodalol, could generate a library of druggable sesquiterpene lactones. The development of a multistage phytomedicine designed as preventive treatment to complement existing malaria control tools appears a challenging but feasible goal.
  • F-actin distribution and function during sexual development in Eimeria maxima. [Journal Article]
    Parasitology 2015; 142(7):855-64Frölich S, Wallach M
  • To determine the involvement of the actin cytoskeleton in macrogametocyte growth and oocyst wall formation, freshly purified macrogametocytes and oocysts were stained with Oregon Green 514 conjugated phalloidin to visualize F-actin microfilaments, while Evans blue staining was used to detect type 1 wall forming bodies (WFB1s) and the outer oocyst wall. The double-labelled parasites were then anal…
  • Eimeria arloingi: further studies on the development of some endogenous stages. [Journal Article]
    Exp Parasitol 2014; 140:12-7Razavi SM, Hashemnia M, Khodakaram-Tafti A
  • The present study investigated the ultrastructural characteristics of gamogony and oocyst wall formation of Eimeria arloingi in experimentally infected kids. The 18 newborn animals allocated to 3 equal groups. Two of groups, A, B were inoculated with a single dose of 1×10(3) and 1×10(5) sporulated oocysts of E. arloingi, respectively. At 7, 14, 21, 28, 35, and 42days postinoculation (DPI), 1 kid …
  • Lack of molecular correlates of Plasmodium vivax ookinete development. [Journal Article]
    Am J Trop Med Hyg 2011; 85(2):207-13Bounkeua V, Li F, … Vinetz JM
  • Previous studies of Plasmodium vivax transmission to Anopheles spp. mosquitoes have not been able to predict mosquito infectivity on the basis of microscopic or molecular quantification of parasites (total parasites in the sample or total number of gametocytes) in infected blood. Two methods for production of P. vivax ookinete cultures in vitro, with yields of 10(6) macrogametocytes, 10(4) zygote…
