Characterization of Polish feline B. henselae isolates by multiple-locus tandem repeat analysis and pulse-field gel electrophoresis.

Knowledge about molecular epidemiology of B. henselae is important for recognizing the geographical distribution of strains and identification of isolates virulent for humans. Eleven Polish feline B.

A new typing technique for the Rickettsiales Ehrlichia ruminantium: multiple-locus variable number tandem repeat analysis.

Ehrlichia ruminantium (ER) is a member of the order Rickettsiales transmitted by Amblyomma ticks. This obligatory intracellular bacterium is the causative agent of a fatal disease in ruminants, named heartwater. It represents a constraint on breeding development in sub-Saharan Africa and in the Caribbean.

Differential effects of Bartonella henselae on human and feline macro- and micro-vascular endothelial cells.

Bartonella henselae, a zoonotic agent, induces tumors of endothelial cells (ECs), namely bacillary angiomatosis and peliosis in immunosuppressed humans but not in cats. In vitro studies on ECs represent to date the only way to explore the interactions between Bartonella henselae and vascular endothelium. However, no comparative study of the interactions between Bartonella henselae and human (incidental host) ECs vs feline (reservoir host) ECs has been carried out because of the absence of any available feline endothelial cell lines.

Molecular epidemiology of feline and human Bartonella henselae isolates.

Multiple locus variable number tandem repeat analysis was performed on 178 Bartonella henselae isolates from 9 countries; 99 profiles were distributed into 2 groups. Human isolates/strains were placed into the second group. Genotype I and II isolates shared no common profile.
