Description:This image depicts a group of epidemiologists in the process of conducting an analysis on a domesticated dog, in order to determine if it had come into contact with plague infected prey, including rodents or rabbits. Here, they were extracting a blood sample from the canine, which would subsequently be tested for the presence of antibodies indicating whether or not this dog had been exposed to plague.
Visual observation are very important, but conclusive proof of an epizootic depends on laboratory testing of sera, fleas, or animal tissues. Serological surveys of wild carnivores, or free-roaming domestic carnivores, are very useful in the detection of zootic plague. A positive antibody titer from a carnivore usually means that it has ingested plague-infected rodent or rabbit, or possibly been bitten by an infected flea.
