  • Group B streptococcus (GBS) is a significant cause of infections in neonates and pregnant women, with Japan implementing guidelines for screening and antibiotic use, yet infections have not decreased significantly.
  • Approximately 15% of pregnant women lack GBS screening, and issues like intermittent colonization lead to early-onset disease; current preventative measures don't address increasing cases of late-onset disease.

Here, we present the case of a 56-year-old man with no history of kidney disease who initially presented with nephrotic syndrome.
