Parkinson’s patients are offered treatment with levodopa, which is altered into dopamine, a neurotransmitter in the brain. In the recent research, scientists at the University of Groningen demonstrated that gut bacteria can convert levodopa into dopamine. Dopamine does not have the ability to cross the blood-brain barrier. This situation minimizes the effectiveness of the drug, even in the presence of inhibitors that should avoid the levodopa conversion. This research can be accessed in the journal Nature Communications.
Sahar El Aidy, Assistant Professor, Microbiology, and principal investigator of the research, proclaimed that the ability of gut bacteria to influence the brain is a well-known fact. She added that there is constant chemical communication between the brain and gut bacteria, the professed gut–brain axis. El Aidy, along with her associates, studied the capability of gut microbiota to affect the bioavailability of levodopa, a medication used in the Parkinson’s disease treatment.
On a similar note, face masks seem to offer the key safety against Staphylococcus aureus bacteria, which are drug-resistant, for household members and hog farm workers, as per the research carried out by scientists from the Johns Hopkins Bloomberg School of Public Health.
In the research, which is available in the journal Environmental Health Perspectives, the researchers tracked approximately 79 household members and about 101 hog farm workers using nasal swabs and asking queries about the use of face mask. This observation was carried out for almost 4 Months period. They discovered that, for workers who were employing face masks on the job continuously during the 4-month research, there was a 50–70% decrease in the probability of noticing hazardous, livestock-derived S. aureus strains in their swabs. They also found about 80–90% decrease in the possibility that household members’ swabs might test positive for such type of strains.
