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...
متن کاملIn vitro susceptibility of Bartonella species to 17 antimicrobial compounds: comparison of Etest and agar dilution.
OBJECTIVES In vitro susceptibility testing of 31 Bartonella spp. strains including 21 Bartonella henselae isolates was performed for 17 antimicrobial agents (telithromycin, four macrolides, five fluoroquinolones, five aminoglycosides, doxycycline and rifampicin). METHODS MICs were determined by agar dilution and Etest using chocolate agar containing 5% defibrinated sheep blood as assay medium...
متن کاملIntraerythrocytic 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.
متن کاملBartonella 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...
متن کاملPhase variation in Bartonella henselae.
Bartonella henselae is a fastidious, Gram-negative bacterial pathogen of cats and humans. Previous workers have shown that serial passage in vitro leads to attenuation of virulence-associated attributes such as expression of pili, invasion of human epithelial cell lines and the stimulation of endothelial cell proliferation. In contrast to the published data, it was found that pilin expression i...
