Interventions

A:"Reuteri?Probiotics Drop"
5 drops daily for 14 days concomitant with 7 days of Augmentin (1 g bd twice daily). Antibiotic and probiotic are taken orally
B:"NESTLéi? Acti-Vi? Low Fat Yogurt"
1 tube daily for 14 days concomitant with 7 days of Augmentin (1 g bd twice daily). Antibiotic and probiotic are taken orally
C:"Adrien Gagnon Probiotic 7 Billion"
3 capsules daily for 14 days concomitant with 7 days of Augmentin (1 g bd twice daily). Antibiotic and probiotic are taken orally
D:Spontaneous recovery after 7 days of Augmentin (1 g bd twice daily) via oral route. Placebo was also not given due to the potential of affecting the microbiome results
