Bad Breath with Antibiotic Resistant Microbes when Orca exhale

When an orca breaks the surface water and exhales, the mighty whale sprays along an array of bacteria, among which some are good and some bad. The new research that published in the journal Scientific Reports focused on the potential role of infectious diseases that are important struggling factors for species getting endangered.

Orcas’ breath samples have unveiled the microbes that are capable of causing disease. Among these microbes, some are multidrug resistant to antibiotics that are mostly used by we human beings. This provides a message with huge impact suggesting how humans are contaminating marine environment.

The study was carried out on four year period that provided array of microorganisms involving bacteria and fungi that are exhaled through orca’s breath. Surprisingly there were healthy microorganisms too, but they are worrisome drug-resistant.

"They're recruiting the bacteria in their habitats," said Stephen Raverty, the study's lead author who is a veterinary pathologist with British Columbia Ministry of Agriculture, Animal Health Centre in Abbotsford.

Orcas which are immunocompromised can be more susceptible towards such bacteria resulting in respiratory disease.

"These animals are subject to many stressors, which reduce the competence of their immune systems," said marine mammal veterinarian Pete Schroeder, co-author of the paper.
