| development, ultrastructure, natural occurrence, and molecular characterization of liebermania patagonica n. g., n. sp., a microsporidian parasite ot the grasshopper tristira magellanica (orthoptera: tristiridae). | a new microsporidium, liebermannia patagonica n. gen., n. sp., is described from midgut and gastric caecum epithelial cells of tristira magellanica, an apterous grasshopper species of southern patagonia, argentina. l.patagonica is diplokaryotic, apansporoblastic, homosporous, and polysporoblastic. transitional (from merogony to sporogony) stages and sporonts of l. patagonica were surrounded by host rough endoplasmic reticulum. the ovocylindrical spores measured 2.9 +/- 0.09 x 1.2 +/- 0.04 microm ... | 2006 | 16524588 |
| establishment of liebermannia dichroplusae n. comb. on the basis of molecular characterization of perezia dichroplusae lange, 1987 (microsporidia). | perezia dichroplusae lange, 1987 is a parasite of the malpighian tubules of an argentine grasshopper, dichroplus elongatus (orthoptera, acrididae, melanoplinae). in order to determine relationships of this microsporidium with perezia nelsoni and with other microsporidia, we sequenced its small subunit ribosomal rna gene (ssu rdna) (genbank accession no. ef016249) and performed phylogenetic analysis of the novel sequence against 17 microsporidian ssu rdna sequences from genbank, using neighbor-jo ... | 2007 | 17552977 |
| morphology and taxonomy of the microsporidium liebermannia covasacrae n. sp. from the grasshopper covasacris pallidinota (orthoptera, acrididae). | during a survey for grasshopper pathogens in argentina in 2005-2006, individual covasacris pallidinota from halophylous grasslands in laprida, buenos aires province were found to be infected with a microsporidium. infection was restricted to the salivary gland epithelial cells. the microsporidium produced ovocylindrical spores averaging 2.6+/-0.28 x 1.4+/-0.12 microm (range 2.2-3.4 x 1.1-1.7 microm), which resembled in size and shape the spores of liebermannia patagonica and l. dichroplusae, two ... | 2009 | 19233189 |
