Research exploring use of the sylvatic plague
vaccine on a broader scale continues with the help of private landowners and tribal, state and federal partners in an effort to promote conservation of grassland habitats and wildlife.
Isolation and characterization of 11 microsatellite loci from Oropsylla hirsuta, a vector of sylvatic plague
hit the prairie dogs--and biologists discovered that they had been wrong in believing that ferrets were immune.
Shirley Basin was chosen first because prairie dog numbers were still low at Meeteetse following the outbreak of sylvatic plague
, a disease caused by the same microorganism responsible for bubonic plague in humans.
Blood tests from the cats and squirrels were taken this week after a cat caught at Rancho Mirage mobile-home park tested positive for sylvatic plague
, which is endemic among ground squirrels in the San Gabriel and Tehachapi mountains.
Since its arrival, sylvatic plague
has readily adapted to and pro foundly influenced wild American rodent populations (5,6).
However, many of those sites have been hit by sylvatic plague
, an introduced disease that is fatal to both prairie dogs and ferrets.
County health officials closed a park east of Altadena after a ground squirrel caught during routine monitoring tested positive for sylvatic plague
To add to the prairie dog's woes, a new threat has arrived on the scene sylvatic plague
In 1985, a sylvatic plague
outbreak caused the number to drop to 58.
The ferret's most recent decline started when a bout of sylvatic plague
, the disease that in humans causes bubonic plague, swept through Wyoming's prairie dog towns in September 1984.
In addition to threats imposed directly by humans, sylvatic plague
(the rodent borne form of bubonic plague), was introduced to the West coast in the early 20th century (via shipboard rats) and has since spread through most western states.
