H2 (Haiti, 2010)
Vibrio cholerae O1 biovar El Tor
Samples of spontaneously passed stool from two  patients who had received a clinical diagnosis of  cholera were cultured. Both patients received standard medical treatment for cholera, as appropriate to their clinical conditions. Bacterial isolates  (H1 and H2) were shipped to the United States,  with the use of an import license for this purpose  (2010-10-108) that was provided through the Centers for Disease Control and Prevention (CDC).  Isolates were identified as V. cholerae and were determined to be susceptible to tetracycline and  erythromycin but resistant to trimethoprim-sulfamethoxazole and nalidixic acid.
