Cystic fibrosis is an inherited disease that causes a buildup of thick mucus in the lungs, leading to repeated bacterial infections that damage the lungs and can cause respiratory failure.

Adding to this problem when the bacterial infection become resistant bacteria the treatment of the patient become really challenging.

On the one hand, antibiotics are one of the most powerful tools to save lives. The breakthrough that saved many lives also gets its dark side. Despite the decreasing efficacy in the treatment of patients and the rise of resistance due to the misuse of antibiotics and not of antibiotics themselves, scientists have found a real downside: the impact on the gut microbiota.

 “a growing number of studies are finding that even a short course of antibiotics can alter the makeup of the bacterial species in the gut.” 

A direct link between climate change and infectious diseases can be explained by one notion: the one health concept.

As a reminder, the one health concept is a concept that stand for the interconnection of human – animal and environment health. Dysregulating one aspect can have an impact on others. In this specific case, the three notions of health are interconnected. As a consequence of climate change, scientists predict that wild animals will be forced to relocate their habitats and will most likely be closer to human population or to farmed animals.
