GLUCOSE CYSTEINE AGAR BASE W/ THIAMINE

Francisella tularensis, a gram-negative aerobic bacillus, is the etiological agent of tularemia, which is primarily a disease of wild animals that is perpetuated in nature by ectoparasites, contaminated environment, cannibalism and acute or chronic carriers. Biting and blood sucking insects serve as vectors. Francisella (formerly known as Pasteurella) cannot be cultured on ordinary medium but require a complex medium containing blood or tissue extracts, thiamine and cysteine. Glucose Cysteine Agar Base w/ Thiamine when supplemented with blood / haemoglobin is recommended for cultivation and enumeration of F. tularensis (Pasteurella tularensis).
