“…Bartonella sp. 1-1C, which was previously isolated from R. norvegicus in Taiwan, 9 was detected in fleas in the present study. In Taiwan, fleas and lice may be efficient vectors for infection of small mammal hosts with several Bartonella species.…”

“…In this study, specificity of some bartonellae for host animals was observed (Table 3). The R. rattus brunneusculus rats carried almost all the rat-origin Bartonella species detected in this study, except B. rochalimae, which was isolated recently from R. norvegicus in Taiwan (19). In our study, S. murinus shrews harbored mostly B. queenslandensis.…”

“…Previously, several reports were made on the occurrence of bartonellae in rodents and other small mammals in Asian countries, including Bangladesh (3), China (28), Indonesia (27), Japan (16), Laos (1), Taiwan (19), and Thailand (2,7,24). Recently, Bai et al (3) reported that 63.2% of B. bengalensis, 32.3% of R. rattus, and 42.9% S. murinus animals collected in Dhaka, Bangladesh, were infected with Bartonella, and the isolates from these animals were genetically related to Bartonella isolates found in America and Europe.…”

Bartonellae were detected in a total of 152 (23.7%) of 642 tissues from 108 (48.4%) of 223 small mammals trapped in several urban areas of Nepal. Based on rpoB and gltA sequence analyses, genotypes belonging to seven known Bartonella species and five genotypes not belonging to previously known species were identified in these animals.Bartonella species are important zoonotic and vector-borne bacteria associated with an increasing array of emerging infections in humans and animals (6,8,21). Identification of new bartonellae, especially in animals that have possible contact with humans, can help to identify new human pathogens (12). Moreover, the close association between rodents and humans throughout the world makes the study of rodent-borne Bartonella essential to determine the extent to which rodents may serve as a source of human infections (7). We conducted a study on the molecular detection of Bartonella in different tissues of Nepalese small mammals.In 1996, a total of 223 small mammals (38 Bandicota bengalensis, 3 Mus musculus castaneus, 90 Rattus rattus brunneusculus, and 92 Suncus murinus animals) were trapped in densely human populated urban areas in Nepal. Details on the trapped animals are given in Table 1. Lung, kidney, and liver tissue samples were collected and shipped to the Centers for Disease Control and Prevention (CDC), Fort Collins, CO. A total of 642 tissue samples were assessed for the presence of Bartonella DNA by rpoB and gltA sequencing as described previously (5, 23).Bartonella was detected in 108 (48.4%) of 223 animals in Nepal: 10 (26.3%) of 38 B. bengalensis rats, 39 (43.3%) of 90 R. rattus brunneusculus rats, and 59 (64.1%) of 92 S. murinus shrews were infected with Bartonella (Table 1). The infection rate varied from 42 to 60% by province. The highest numbers of infected animals were in the Kathmandu and Lalitpur districts. This was because S. murinus was the most commonly infected species and the highest numbers of animals of this species were trapped in these areas. Bandicoots were the most commonly infected subjects in Kathmandu, but fewer numbers of these animals (n ϭ 2) were trapped in Bhaktapur and Lalitpur. Only three M. musculus mice were collected (only in Kathmandu) in this study, and none of these animals were positive for Bartonella. A total of 152 (23.7%) of 642 tissue samples were positive for Bartonella. Of the three tissue types, kidney samples (29.6%) and liver samples (25.6%) were more frequently infected with Bartonella than the lung samples (17.3%; P ϭ 0.03 and 0.04, respectively) ( Table 2). DNA sequencing revealed 37 and 20 rpoB and gltA genotypes, respectively, of which 31 and 15 belonged to B. rattimassiliensis, B. queenslandensis, B. elizabethae, B. tribocorum, "B. rochalimae," or "B. phoceensis" and the other 6 and 5 genotypes, respectively, were not genetically related to known bartonellae ( Fig. 1 and 2). These novel genetic groups were found in S. murinus and R. rattus brunneusculus animals. The human pathogen B. elizabethae was detected in R. rattus br...

Epidemiological studies worldwide have reported a high prevalence and a great diversity of Bartonella species, both in rodents and their flea parasites. The interaction among Bartonella, wild rodents, and fleas reflects a high degree of adaptation among these organisms. Vertical and horizontal efficient Bartonella transmission pathways within flea communities and from fleas to rodents have been documented in competence studies, suggesting that fleas are key players in the transmission of Bartonella to rodents. Exploration of the ecological traits of rodents and their fleas may shed light on the mechanisms used by bartonellae to become established in these organisms. The present review explores the interrelations within the Bartonella-rodent-flea system. The role of the latter two components is emphasized.
