Rodent Disease Survey

Rodent Disease Survey

Laboratory staff conducted one survey of wild rodents in the month of May.  The surveys took place in Montara.  Blood samples were taken from captured rodents by a subocular bleed with a microcapillary tube and on nobuto paper strips. This blood was sent to the California Department of Public Health for testing of plague and hantavirus. All rodents tested negative for plague. Results of hantavirus testing are pending.

The rodents trapped included Dusky-footed woodrats, deer mice (genus Peromyscus) and shrews. Only the Peromyscus mice are tested for hantavirus, as the other rodent species do not carry the virus. Last May the District performed a rodent survey in the same area and detected hantavirus in one of thirteen mice.
