Orientalis biovar of the causative agent of plague. Yersinia pestis biovar Orientalis str. MG05-1020

Yersinia pestis biovar Orientalis str. MG05-1020. Yersinia pestis biovar Orientalis str. MG05-1020 was isolated from pus collected from a blister on the abdomen of an 8 year old male patient (infection is presumed to have occurred at the site of the flea bite). The culture was confirmed at Chapa Hospital in Antananarivo, Madagascar. The isolate is positive for anti-F1 direct fluorescent antibody and was lysed by Y. pestis-specific bacteriophage. MG05-1020 is sensitive to chloramphenicol, trimethoprim/sulfamethoxazole, ciprofloxacin, gentamicin, streptomycin, and doxycycline. Virulence studies showed that 3.36 x 103 cfu killed mice within four days. This organism is being sequenced for comparative genome analysis of Yersinia pestis strains isolated from different parts of the world.
