ARIAS  LEON, Gabriela et al. Study of Systemic Infection by Herpesvirus Complicated With Cryptosporidium spp.  in a Gulf Stream Spotted Dolphin (Stenella frontalis. Cuvier, 1829).. Rev. Cient. (Maracaibo) [online]. 2008, vol.18, n.3, pp.243-252. ISSN 0798-2259.

The present study was made, in the event of a young female dolphin of the specie Stenella frontalis, that was found stranded in Playa Dorada, in Boca de Aroa, in the Falcón State, the 07/30/02, in Venezuela. She was kept in a facility for a period of three days, during this period of time, she was evaluated periodically whit not invasive technique, and morphometry data recollection. She died the 08/01/02 due to respiratory arrest, which caused a cardiac arrest. A macroscopic postmortem study was made, taking samples and keeping them in formaldehyde 10% for histopathology study of the following organs: heart, lungs, stomach, large intestine, liver, kidney and lesions of the skin with a fat layer, they were processed in the Pathologic Anatomy laboratory of the Universidad Central de Venezuela. Because of the results of the microscopic study, it was determined that the dolphin presented a systemic infection, because of a primary infection by Herpesvirus spp., related with a secondary infection by Cryptosporidium spp., which was complicated with stress due to the beaching. The bibliographic revue reports that the parasitosis by Cryptosporidium spp. is not present to Venezuela in the Cetacean order, according to the compiled information about the studied parasites for this order. The skeleton is currently in the Scientific Museum of the Biological Station Rancho Grande - MARNR.
