Dolphins are Imitating Human Trend and Becoming Antibiotic-Resistant, Study Finds

Nowadays, organisms are becoming resistant to antibiotics. Now it has become a significant concern and the most massive health challenge worldwide. On one side, many common bacterial infections are prospering and becoming resistant to the medicines. On the other hand, scientists are swiftly developing new antibiotic drugs to tackle the issue. Apart from all this, a new concern is emerging across the world. Researchers have claimed that antibiotic resistance is soaring in dolphins. Even more, those creatures are copying the trend found in humans. An international team of scientists had participated in a large-scale study. Researchers from Harbor Branch Oceanographic Institute, a branch at Florida Atlantic University, participated together with Georgia Aquarium. Even more, scientists from Colorado State University and the Medical University of South Carolina have joined the research.

To reveal the fact scientists had gathered samples between the period of 2003 and 2015 from Florida’s Indian River Lagoon. During the analysis, they have studies various disease-causing agents present in the gastric fluid, blowholes, and feces of bottlenose dolphins. Adan Schaefer from Florida Atlantic University is the leading author of the study published in the journal Aquatic Mammals. As per Adam, a large number of people reside in the coastal region along with crucial environmental issues. Some of the major concerns include outflow from the land, freshwater flow from canals, septic tanks, and many more. Scientists have studied 733 samples collected from 171 dolphins.

As a result, they have found that more than 80% of the specimens consisted of a pathogen resistant to a minimum of one antibiotic. Even more, those bacteria are most resistant to erythromycin. It is an antibiotic drug usually used to cure sexually transmitted infections, chest infections, acne. Experts often use medicine to treat other illnesses like syphilis and chlamydia. Resistance to the antibiotic ciprofloxacin among E. coli agents has raised by two times throughout the study. Scientists surmise those bacteria are simulating human trends of infection. All in all, the increasing antibiotic resistance among dolphins reveals a risk for humans as well.
