Researchers find tumors in two turtles in danger of extinction

Researchers from the Department of Wildlife of the Interdisciplinary Center for Regional Integral Development Research (CIIDIR), in Guasave, Sinaloa , found two new cases of sea turtles with tumors generated by water pollution.

The fibropapillomas are caused in these animals by high concentrations of heavy metals in the water they inhabit.

MSC-1, the drug that prevents metastasis and reduces tumors.

Since June of this year, researchers from the National Polytechnic Institute (IPN) belonging to CIIDIR studied these types of tumors that were initially attributed to stress in animals.

However, the IPN reported that in addition to this factor, the main cause of these tumors is environmental contamination, which weakens the immune system and leads to the development of this infectious viral disease that affects both externally and internally and constitutes one of the health problems with great systemic involvement in sea turtles.

External tumors occur mainly in fins, skin, tissues near the eyes, cloacal region, plastron and shell, limiting their ability to move and feed; while internal fibroids are more common in the liver, lungs and heart affecting respiratory, digestive and cardiac functions.

This study was carried out in 58 specimens of the golf turtle (Lepidochelys olivácea) and in 24 specimens of the black turtle (Chelonia agassizii), endangered species found in different aquatic areas of the state of Sinaloa.

Although it is not a contagious condition, CIIDIR researchers warned of the risk of water pollution in human development.

Among the pollutants present in the water are pesticides, heavy metals and organochlorines.

Also in May of the same year, white turtle specimens arrived in some coasts of the Mexican Caribbean, one of the largest species in the world and which were also invaded by these tumors.

In several coasts of America, specimens with this type of tumors have been presented, the first case registered was in the state of Florida, United States, and later in Venezuela between 1999 and 2014, when 391 infected turtles were reported.

So far these types of tumors have presented fins, skin, tissues close to the eyes, cloacal region, plastron and shell.
