Susceptibility of Polish Bartonella henselae Strains

Susceptibility of Polish Bartonella henselae strains.

Due to the fastidious nature of B. henselae and the limited number of available isolates worldwide, there are few data on its in vitro susceptibility to antibiotics. We determined the minimal inhibitory concentrations (MIC) of ten antimicrobial agents against 11 feline isolates of B. henselae by Etest method. The lowest MICs were obtained for rifampicin < or = 0.002 mg/L. MICs of all isolates w...

Editorial Response: Are all Bartonella henselae Strains Created Equal?

Antigenic and genotypic relationships between Bartonella henselae strains.

The ubiquitous feline intraerythrocytic pathogen Bartonella henselae causes a range of important human infections, and seroprevalence in blood donors in Australia is around 5% (6). Two antigenically distinct subtypes have been described, named for the type strain (Houston-1) and the more recently recognized Marseille strain (5), which have characteristic DNA sequences in the 16S rRNA gene (rDNA...

Intraerythrocytic presence of Bartonella henselae.

Recent reports in the medical literature emphasize the risk of zoonotic disease and the high degree of prevalence of asymptomatic feline infection with Bartonella (Rochalimaea) henselae. While investigating Bartonella bacteremia in cats, we used transmission electron microscopy to demonstrate B. henselae in the erythrocytes of persistently bacteremic cats.

Bartonella henselae in Porpoise Blood

We report detection of Bartonella henselae DNA in blood samples from 2 harbor porpoises (Phocoena phocoena). By using real-time polymerase chain reaction, we directly amplified Bartonella species DNA from blood of a harbor porpoise stranded along the northern North Carolina coast and from a pre-enrichment blood culture from a second harbor porpoise. The second porpoise was captured out of habit...
