Coxiella burnetii Genotyping
Multispacer sequence typing is the first reliable method for typing Coxiella burnetii isolates.
Naming of Rickettsiae and Rickettsial Diseases
Taxonomic rules and appropriate approaches to valid naming of rickettsial species and the diseases they cause are reviewed. Expand
Rickettsia slovaca sp. nov., a member of the spotted fever group rickettsiae.
The name Rickettsia slovaca sp. nov. (type strain is strain B) is proposed for a member of the spotted fever group (SFG) rickettsiae which was isolated from Dermacentor marginatus ticks in SlovakiaExpand
Characterization of a New Spotted Fever Group Rickettsia Detected in Ixodes ricinus (Acari: Ixodidae) Collected in Slovakia
Phylogenetic relationships inferred from the comparison of these sequences with those of other members of the genus Rickettsia indicate that IRS3 and IRS4 constitute a new rickettsial genotype and form a separate cluster among the spotted fever group ricksettsiae. Expand
A Novel Obligate Intracellular Gamma-Proteobacterium Associated with Ixodid Ticks, Diplorickettsia massiliensis, Gen. Nov., Sp. Nov
It is proposed that strain 20B, an obligate intracellular gamma-proteobacterium isolated from the actively questing hard tick Ixodes ricinus, is proposed to be classified in the new genus Diplorickettsia as the type strain of a novel species named Diplorbacterium massiliensis sp. Expand
Survey of laboratory-acquired infections around the world in biosafety level 3 and 4 laboratories
The analysis of the survey reveals that laboratory-acquired infections have been infrequent and even rare in recent years, and human errors represent a very high percentage of the cases. Expand
Penetration of host cells by Rickettsia rickettsii appears to be mediated by a phospholipase of rickettsial origin
Results show that pretreatment of R. rickettsii, but not of host cells, with a specific chemical inhibitor of phospholipase, and also antiserum to this enzyme, significantly reduces uptake of the organism and its ability to cause plaque formation. Expand
Multiple tick-associated bacteria in Ixodes ricinus from Slovakia.
T ticks collected in the Rovinka forest in Slovakia were tested by real-time and routine single-step PCR for the presence of different pathogenic and endosymbiotic bacteria, and bacteria with unknown or suspected pathogenicity for humans were identified. Expand
Identification of protein candidates for the serodiagnosis of Q fever endocarditis by an immunoproteomic approach
29 candidate antigenic proteins, including arginine repressor and OmpH, were recognised exclusively by the sera of patients with Q fever endocarditis and are promising candidates for the development of serodiagnostic assays for Q feverendocarditis. Expand
Phylogeny of Rickettsia spp. inferred by comparing sequences of 'gene D', which encodes an intracytoplasmic protein.
'Gene D' is the PS120-protein-encoding gene, first described in Rickettsia conorii and Rickettsia japonica. Sequence analysis of a 3030 bp fragment of 'gene D' in 24 representatives of the genusExpand
