Abstract
Background and Objectives: Vector-borne bacterial diseases represent a substantial public health burden and rodents have been recognized as important reservoir hosts for many zoonotic pathogens. This study investigates bacterial pathogens in a small mammal community of the southwestern United States of America. Methods: A total of 473 samples from 13 wild rodent and 1 lagomorph species were tested for pathogens of public health significance: Bartonella, Brucella, Yersinia, Borrelia, Rickettsia spp., and Anaplasma phagocytophilum. Results: Three animals were positive for Yersinia pestis, and one Sylvilagus audubonii had a novel Borrelia sp. of the relapsing fever group. No Brucella, Rickettsia, or A. phagocytophilum infections were detected. Bartonella prevalence ranged between 0% and 87.5% by animal species, with 74.3% in the predominant Neotoma micropus and 78% in the second most abundant N. albigula. The mean duration of Bartonella bacteremia in mark-recaptured N. micropus and N. albigula was 4.4 months, ranging from <1 to 18 months, and differed among Bartonella genogroups. Phylogenetic analysis of the Bartonella citrate synthase gene (gltA) revealed 9 genogroups and 13 subgroups. Seven genogroups clustered with known or previously reported Bartonella species and strains while two were distant enough to represent new Bartonella species. We report, for the first time, the detection of Bartonella alsatica in North America in Sylvilagus audubonii and expand the known host range of Bartonella washoensis to include Otospermophilus variegatus. Interpretation and Conclusion: This work broadens our knowledge of the hosts and geographic range of bacterial pathogens that could guide future surveillance efforts and improves our understanding of the dynamics of Bartonella infection in wild small mammals.

Abstract
Rodent-borne bartonellae have been identified as human pathogens. Little is known about Bartonella infections in woodrat hosts and their fleas and how woodrat-flea associations may affect the dynamics of Bartonella infections. We collected blood samples and fleas from two species of woodrats (Neotoma micropus and N. albigula) from Santa Fe County, NM, from 2002-2005. The most predominant flea species were Orchopeas sexdentatus and O. neotomae. Bartonella prevalence in woodrats was 64% overall, with a lower prevalence occurring in the pre-reproductive period compared to the early and late reproductive periods. A negative correlation between Bartonella prevalence in N. micropus and weight of N. micropus was observed. Flea load in Neotoma species was highest in the early reproductive period compared to the pre- and late reproductive periods and was higher in N. micropus compared to N. albigula. Bartonella prevalence in fleas was highest in the early reproductive period and lowest in the late reproductive period, and it was higher in fleas collected from N. micropus than in fleas collected from N. albigula. Abundance of O. sexdentatus was significantly higher in N. micropus compared to N. albigula, and abundance of O. sexdentatus and O. neotomae was highest in the early reproductive period. No direct correlations were found either between Bartonella prevalence in woodrats and in fleas or between Bartonella prevalence in woodrats and flea loads. Out of 25 partially characterized Bartonella isolates from Neotoma woodrats, 24 belonged to one genogroup based on sequencing of the gltA gene.
