Pengaruh ASI Terhadap Infeksi Rotavirus Neonatal

Gula dan mikrobioma air susu ibu (ASI) mempengaruhi infeksi rotavirus (virus penyebab diare umumnya pada bayi dan anak) neonatal (bayi baru lahir misalnya kurang dari 28 hari). Interaksi antara gula dan mikrobioma (mikro-organisma dalam tubuh manusia) dalam ASI memengaruhi infeksi rotavirus neonatal. Begitu hasil riset dan analisis multi disiplin dari tim peneliti berbagai universitas yang dirilis oleh jurnal Nature Communications November 2018.

“We began our investigation years ago by determining that a particular strain of rotavirus was associated with both asymptomatic infections and clinical symptoms in newborns. Rotavirus infection causes diarrhea and vomiting primarily in children younger than 5, with the exception of babies younger than 28 days of age, who usually have no symptoms. We found that some of the same specific sugars in breast milk that increase infectivity of cells in culture are present in the milk of mothers of newborns with symptomatic infection,”ujar Dr. Sasirekha Ramani, asisten profesor virologi molekular dan mikrobiologi pada Baylor College of Medicine (India) (Science Daily, 27/11/2018).

Studi ilmiah itu menghasilkan pemahaman baru tentang infeksi rotavirus pada bayi dan anak-anak dan mengidentifikasi unsur maternal yang dapat meningkatkan kinerja vaksin rotavirus (Baylor College of Medicine, 2018). Riset itu melibatkan ahli dari Baylor College of Medicine, Newcastle University, University of California, Christian Medical College (India), Translational Health and Science Technology Institute (India), dan didukung oleh National Institutes of Health dan Center for Metagenomics and Microbiome Research.

“These discoveries are a prime example of the urgent need to improve our understanding of the composition and variation in breast milk components. Understanding how rotavirus and other pathogens can take advantage of breast milk components will guide the development of new vaccination strategies to stay ahead in the host-pathogen arms race,” ungkap Dr. Lars Bode, asisten profesor pediatrik dan direktur Collaborative Human Milk Research, Larsson-Rosenquist Foundation Mother-Milk-Infant Center of Research Excellence, University of California, San Diego, Amerika Serikat (Science Daily, 2018).
