| 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 ... | 2012 | 22241989 |
| persistence of neorickettsiae helminthoeca in an endoparasite of the pacific salmon. | silver salmon (oncorhynchus kisutch) infected with the metacercariae of the "salmon poisoning" fluke (nanophyetus salmincola) remain infected after they have migrated to sea. metacercariae remain viable in such salmon for at least 33(1/2) months. these metacercariae are capable of transmitting salmon disease (neorickettsiae helminthoeca) to susceptible dogs throughout this period. | 1964 | 14171553 |

| prevalence of mycoplasma haemofelis, 'candidatus mycoplasma haemominutum', bartonella species, ehrlichia species, and anaplasma phagocytophilum dna in the blood of cats with anemia. | hemoplasmas are known causes of anemia in some cats and some bartonella species have been associated with anemia in people and in dogs. in this retrospective study, we used polymerase chain reaction (pcr) assays to determine the prevalence rates of mycoplasma haemofelis, 'candidatus m haemominutum', a phagocytophilum, ehrlichia species, and bartonella species dna in the blood of cats with anemia and a control group of healthy cats. dna of the organisms was amplified from 22 of 89 cats with anemi ... | 2007 | 16846745 |
| 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 ... | 2004 | 15388752 |
| wolbachia surface protein (wsp) inhibits apoptosis in human neutrophils. | polymorphonuclear cells (pmns) are essential for the innate immune response against invading bacteria. at the same time, modulation of pmns' apoptosis or cell death by bacteria has emerged as a mechanism of pathogenesis. wolbachia bacteria are gram-negative endosymbionts of filarial nematodes and arthropods, phylogenetically related to the genera anaplasma, ehrlichia and neorickettsia (family anaplasmataceae). although several pathogens are known to interfere with apoptosis, there is only limite ... | 2007 | 17241395 |
