| isolation and genetic characterization of a bartonella strain closely related to bartonella tribocorum and bartonella elizabethae in israeli commensal rats. | ten bartonella isolates were cultured from blood drawn from black rats (rattus rattus) captured in the tel aviv area. genetic characterization included amplification and sequencing of five gene fragments including the ribc, rpob, 16s, groel, and glta and the 16s-23s intergenic spacer region. sequence comparisons showed that all 10 isolates were identical in all genes studied comprising a total of 3,873 bp analyzed. the sequences of each of the partial genes analyzed indicated a high sequence sim ... | 2009 | 19556567 |
| prevalence and diversity of bartonella species in commensal rodents and ectoparasites from nigeria, west africa. | bartonellae are fastidious bacteria causing persistent bacteremia in humans and a wide variety of animals. in recent years there is an increasing interest in mammalian bartonelloses in general and in rodent bartonelloses in particular. to date, no studies investigating the presence of bartonella spp. in rodents and ectoparasites from nigeria were carried out. | 2013 | 23738028 |
| bartonella species in fleas from palestinian territories: prevalence and genetic diversity. | bartonellosis is an infectious bacterial disease. the prevalence and genetic characteristics of bartonella spp. in fleas of wild and domestic animals from palestinian territories are described. flea samples (n=289) were collected from 121 cats, 135 dogs, 26 hyraxes and seven rats from northern (n=165), central (n=113), and southern palestinian territories (n=11). the prevalent flea species were: ctenocephalides felis (n=119/289; 41.2%), ctenocephalides canis (n=159/289; 55%), and xenopsylla sp. ... | 2014 | 25424254 |
| elucidating transmission dynamics and host-parasite-vector relationships for rodent-borne bartonella spp. in madagascar. | bartonella spp. are erythrocytic bacteria transmitted via arthropod vectors, which infect a broad range of vertebrate hosts, including humans. we investigated transmission dynamics and host-parasite-vector relationships for potentially zoonotic bartonella spp. in invasive rattus rattus hosts and associated arthropod ectoparasites in madagascar. we identified five distinct species of bartonella (b. elizabethae 1, b. elizabethae 2, b. phoceensis 1, b. rattimassiliensis 1, and b. tribocorum 1) infe ... | 2017 | 28351673 |
| bartonella spp. in small mammals, benin. | this study aimed to investigate the prevalence and genetic diversity of bartonella organisms in small mammals in cotonou, benin. we captured 163 rodents and 12 insectivores and successfully detected bartonella dna from 13 of the 175 small mammal individuals. bartonella spp., identical or closely related to bartonella elizabethae, bartonella tribocorum, and bartonella rochalimae, was detected. a potential new bartonella species, proposed as candidatus bartonella mastomydis, was found in three mas ... | 2016 | 26910412 |
| the distribution and diversity of bartonella species in rodents and their ectoparasites across thailand. | our study highlights the surveillance of bartonella species among rodents and their associated ectoparasites (ticks, fleas, lice, and mites) in several regions across thailand. a total of 619 rodents and 554 pooled ectoparasites (287 mite pools, 62 flea pools, 35 louse pools, and 170 tick pools) were collected from 8 provinces within 4 regions of thailand. bandicota indica (279), rattus rattus (163), and r. exulans (96) were the most prevalent species of rats collected in this study. real-time p ... | 2015 | 26484537 |
