Groups of Swiss Webster outbred mice were each inoculated with one of four bartonella strains originally isolated from Rattus spp. at doses ranging from 101 to 107 bacteria per mouse. One strain, Rn1691yn (Bartonella coopersplainensis-like), infected mice and produced bacteremias at levels up to 105 bacteria/ml of blood and from 3 to 8 weeks duration. A dose dependent response was also observed with differing proportions of mice bacteremic following inoculation at different doses. In addition weeks-to-months long lags in bacteremia manifestation occurred following lower dose exposures. The possibility of bacterial transmission from bacteremic mice to uninfected cagemates was assessed and no naïve mice became infected from contacts with infected mice. Finally, a subset of bacteremic mice inoculated with high doses of Rn1691yn were examined histopathologically and multifocal, granulomatous lesions were detected in both liver and kidneys. The host specificity and infectivity of the strains is discussed in relation to their potential for zoonotic transmission to incidental hosts.
