Chlamydia felis is an important ocular pathogen in cats worldwide. A multilocus variable-number tandem-repeat analysis (MLVA) system for the detection of tandem repeats across the whole genome of C. felis strain Fe/C-56 was developed. Nine selected genetic loci were tested by MLVA in 17 C. felis isolates, including the C. felis Baker vaccine strain, and 122 clinical samples from different geogr...
Endemic melioidosis is caused by genetically diverse Burkholderia pseudomallei strains. However, clonal outbreaks (multiple cases caused by 1 strain) have occurred, such as from contaminated potable water. B. pseudomallei is designated a group B bioterrorism agent, which necessitates rapidly recognizing point-source outbreaks. Pulsed-field gel electrophoresis (PFGE) and multilocus sequence typi...
Fifty-three strains belonging to the pathogenic species Leptospira interrogans and Leptospira kirschneri were analyzed by multilocus sequence analysis. The species formed two distinct branches. In the L. interrogans branch, the phylogenetic tree clustered the strains into three subgroups. Genogroups and serogroups were superimposed but not strictly.
Borrelia burgdorferi sensu lato is a species complex that includes the causative agents of Lyme borreliosis (LB). Classification of the complex was greatly influenced by the method of multilocus sequence typing (MLST), proposed in 2008 and analyzing the spatial distribution of sequence types (STs). Despite the fact that Russia is the largest natural focus of LB to date, it is represented by onl...
The genus Brucella (Mayer and Shaw, 1920) currently consists often species with validly published names. Within most species further differentiation into biovars exists. Genetically, all Brucella species are highly related to each other, exhibiting sequence similarity values of 98% to 100% in aligned regions (core genome). The population structure is clonal. Despite this close genetic relatedne...
To study the population genetic structure of Pseudomonas aeruginosa, we developed a multilocus sequence typing scheme. The sequences of internal fragments of seven housekeeping genes were obtained for 34 P. aeruginosa isolates from patients hospitalized in five different European cities. Twenty-six different allelic profiles were identified. The mean allelic diversity was 0.854 (range: 0.606-0....
