legionella pneumophila secretes a mitochondrial carrier protein during infection.the mitochondrial carrier family (mcf) is a signature group of integral membrane proteins that transport metabolites across the mitochondrial inner membrane in eukaryotes. mcf proteins are characterized by six transmembrane segments that assemble to form a highly-selective channel for metabolite transport. we discovered a novel mcf member, termed legionellanucleotide carrier protein (lncp), encoded in the genome of legionella pneumophila, the causative agent of legionnaire's disease. lncp was se ...201222241989
neorickettsia risticii is vertically transmitted in the trematode acanthatrium oregonense and horizontally transmitted to bats.potomac horse fever is known to be transmitted through the ingestion of caddisflies parasitized with neorickettsia (formerly ehrlichia) risticii-infected metacercaria. however, the species of trematode involved and how n. risticii is maintained in nature are unknown. in this study, gravid trematodes were recovered from the intestines of 12 out of 15 eptesicus fuscus big brown bats and eight out of nine myotis lucifugus little brown bats from various sites in pennsylvania, usa. trematode specimen ...200515658987
ultrastructure and phylogenetic analysis of 'candidatus neoehrlichia mikurensis' in the family anaplasmataceae, isolated from wild rats and found in ixodes ovatus ticks.a novel bacterium that infects laboratory rats was isolated from wild rattus norvegicus rats in japan. transmission electron microscopy of the spleen tissue revealed small cocci surrounded by an inner membrane and a thin, rippled outer membrane in a membrane-bound inclusion within the cytoplasm of endothelial cells. phylogenetic analysis of the 16s rrna gene sequence of the bacterium found in r. norvegicus rats and ixodes ovatus ticks in japan revealed that the organism represents a novel clade ...200415388752
