| natural infections of richardson's ground squirrels with western equine encephalomyelitis virus, saskatchewan, canada, 1964-1973. | a survey (1964-1973) was conducted on naturally occurring western equine encephalomyelitis (wee) virus infections of richardson's ground squirrels (rgs) in agricultural areas of saskatchewan. the survey included both serology and virus isolation attempts on live-trapped wild squirrels. throughout the study, seropostive squirrels were found in the known enzootic regions of the province each summer. the infections rate was high (11.6% of 250) in the epidemic year of 1965 and low (less than 2% o ... | 1975 | 1148947 |
| rodent-associated bartonella in saskatchewan, canada. | six species of wild rodents were sampled at 10 sites in 2002 and 2003 to determine the prevalence of bartonella infections in rodent communities near saskatoon, saskatchewan, canada. isolates were characterized genotypically and compared with isolates found at other locations. of 104 wild rodents examined, 57% were infected with bartonella and prevalence within species varied from 49% for richardson's ground squirrels (spermophilus richardsonii) to 90% for franklin's ground squirrels (s. frankli ... | 2005 | 16417436 |
| diversity of bartonella genotypes in richardson's ground squirrel populations. | the diversity and dynamics of bartonella genotypes found in wild richardson's ground squirrels (rgs), spermophilus richardsonii were monitored at multiple sites in saskatchewan, canada from 2002 to 2004. based on sequence analysis of a portion of the bartonella citrate synthase (glta) gene, four different genotypes were detected in 233 isolates from 176 animals. the majority (87%) of sequences were identified as genotype h, with genotypes i, j, and k accounting for 8%, 4%, and 1% of sequences, r ... | 2006 | 17187575 |
| demographic features of bartonella infections in richardson's ground squirrels (spermophilus richardsonii). | the epidemiology of bartonella infections in richardson's ground squirrels (spermophilus richardsonii) was studied at multiple sites in saskatchewan, canada, from 2002 to 2004. the overall prevalence of bartonella infection was 48%. juvenile squirrels were significantly more likely to be infected with bartonella than were adults (58% and 37%, respectively), and juvenile animals also were significantly more likely to have high levels of bacteremia compared to adult animals. prevalence of bartonel ... | 2006 | 17255440 |
