Babies born via C-section and exposed to antibiotics may face a higher risk of developing antibiotic resistance genes, a recent study reveals. Explore how factors like delivery method, premature birth, and antibiotic use impact infant gut microbiomes and potential interventions in our latest blog post.
First up, a meta-analysis of genomic data on infant gut microbiomes from 10 countries has shed light on some concerning trends. It turns out that factors like C-section delivery, antibiotic use, and prematurity are associated with an increased presence of antibiotic resistance genes in the gut. This highlights the importance of judicious antibiotic use, especially in preterm infants, as it has been linked to a reduction in the diversity of gut bacteria.
Interestingly, Enterobacterales, particularly Escherichia coli, play a significant role in carrying antibiotic resistance genes in infants. Additionally, infants from South Africa and Zimbabwe were found to have higher levels of these genes compared to their European counterparts.
Shifting gears to COVID-19, a study has revealed that some patients may experience persistent loss of smell even a year after being infected. Those with a history of COVID-19 were more likely to report smell loss and had lower scores on smell identification tests.
On a concerning note, children born to mothers infected with the dengue virus during pregnancy face health challenges, with a higher risk of very or extremely low birth weight. This risk can impact their health for at least the first 3 years of life. The rise in dengue fever cases, especially in countries like Brazil, is also a cause for alarm.
Lastly, the link between Cesarean birth, antibiotic use, and prematurity with increased gut carriage of antibiotic resistance genes in infants underscores the need for targeted interventions such as probiotics to address antimicrobial resistance.
