parasites and selected diseases of collared peccaries (tayassu tajacu) in the trans-pecos region of texas.fifty-five collared peccaries (tayassu tajacu) were collected from october 1988 through april 1991 from five counties within the trans-pecos region of texas (usa) to monitor for diseases and parasites. no endoparasites were recovered on gross examination. antibody to borrelia burgdorferi was documented in one (2%) of 55 specimens. three (6%) of 54 collared peccaries were positive for yersinia pestis antibodies. all collared peccaries were negative for antibodies against brucella spp., francisell ...19968827690
an outbreak of francisella tularensis in captive prairie dogs: an immunohistochemical immunohistochemical assay was developed and tested for detection of francisella tularensis lipopolysaccaride antigen in tissues of captive prairie dogs (cynomys ludovicianus). tissues from 59 cases of f. tularensis were examined by this technique, which was corroborated by direct fluorescent antibody assay and direct isolation of the organism. in infected prairie dogs, studies indicated multiple, severe, necroprurulent foci occurring in the liver, lung, spleen, terminal ileum, and mandibular ...200415053367
laboratory analysis of tularemia in wild-trapped, commercially traded prairie dogs, texas, 2002.oropharyngeal tularemia was identified as the cause of a die-off in captured wild prairie dogs at a commercial exotic animal facility in texas. from this point source, francisella tularensis-infected prairie dogs were traced to animals distributed to the czech republic and to a texas pet shop. f. tularensis culture isolates were recovered tissue specimens from 63 prairie dogs, including one each from the secondary distribution sites. molecular and biochemical subtyping indicated that all isolate ...200415109407
first reported prairie dog-to-human tularemia transmission, texas, 2002.a tularemia outbreak, caused by francisella tularensis type b, occurred among wild-caught, commercially traded prairie dogs. f. tularensis microagglutination titers in one exposed person indicated recent infection. these findings represent the first evidence for prairie-dog-to-human tularemia transmission and demonstrate potential human health risks of the exotic pet trade.200415109417
common ancestry and novel genetic traits of francisella novicida-like isolates from north america and australia as revealed by comparative genomic analyses.francisella novicida is a close relative of francisella tularensis, the causative agent of tularemia. the genomes of f. novicida-like clinical isolates 3523 (australian strain) and fx1 (texas strain) were sequenced and compared to f. novicida strain u112 and f. tularensis strain schu s4. the strain 3523 chromosome is 1,945,310 bp and contains 1,854 protein-coding genes. the strain fx1 chromosome is 1,913,619 bp and contains 1,819 protein-coding genes. nucmer analyses revealed that the genomes of ...201121666011
