Glanders - Glaucomys Volans

glanders

(glăn′dĕrz) A contagious infection caused by Burkholderia mallei in horses, donkeys, mules, and other animals. It is communicable to humans, but no cases have occurred in the Western Hemisphere since 1938. Experience with the disease is limited, but sulfa drugs are the recommended therapy.

 SYMPTOMS: Patients develop fever, inflammation of the skin and mucous membranes (esp. in the nasal cavity), with formation of ulcers and abscesses. Small subcutaneous nodules develop, break down, and give rise to ulcers. Beginning as small areas, these tend to spread and coalesce and finally involve large areas that exude a viscid, mucopurulent discharge with a foul odor. The infection may occur in an acute or chronic form. In the acute septicemic form, prognosis is grave and the disease is almost invariably fatal.

Glanzmann thrombasthenia

(glanz′man″) [Edward Glanzmann, Swiss pediatrician, 1887–1959] A rare autosomal recessive abnormality of platelet glycoprotein IIb-IIIa, characterized by easy bruising and epistaxis that sometimes requires blood transfusions.
