Alcohol consumption and antibiotic resistance may be linked through several factors. While moderate alcohol use is generally not considered a significant risk factor for antibiotic resistance, excessive alcohol consumption can weaken the immune system, making individuals more susceptible to infections [1]. This increased susceptibility might lead to a higher likelihood of antibiotic use and potential development of antibiotic-resistant bacteria.

Moreover, alcohol can have a direct impact on the gut microbiome, disrupting the balance of beneficial and harmful bacteria [2]. This dysbiosis might facilitate the growth of antibiotic-resistant bacteria, further contributing to the antibiotic resistance problem.

In addition, alcohol is a significant global health issue, and alcohol-related harm can strain healthcare systems, potentially leading to inappropriate antibiotic prescribing and misuse [3]. This overuse and misuse of antibiotics can accelerate the development and spread of antibiotic-resistant bacteria.

Lastly, the production and distribution of alcoholic beverages can indirectly contribute to antibiotic resistance. For instance, the use of antibiotics in alcohol production, particularly in the brewing industry, has been reported [4]. Misuse or overuse of antibiotics in these settings can lead to the emergence of antibiotic-resistant bacteria, posing a risk to both workers and consumers.

In summary, alcohol consumption can be indirectly linked to antibiotic resistance through weakened immune systems, disrupted gut microbiomes, and inappropriate antibiotic use due to alcohol-related harm. Additionally, the use of antibiotics in alcohol production can directly contribute to antibiotic resistance.
