Abstract
Invasive Streptococcus agalactiae (Group B streptococci, GBS) infections result in a large burden of disease globally. Changes in clinical and molecular epidemiology, as well as antibiotic resistance patterns, are being described globally amongst GBS isolates. Very little is known about the characteristics of invasive GBS disease in the Australian setting. Therefore, this study aimed to define the clinical and genomic characteristics of invasive GBS isolates from the Sunshine Coast region in Australia. Thirty-two isolates were identified over a 3-year period. Known risk factors for disease were present in 71.9% and the leading site of disease was the skin and soft tissue (40.6%). Sequence types (ST) 1, 17 and 23 made up 50% with ST17 making up 56.2% of the total. Serotype Ia was the most prevalent (9/32, 28.1%). Clindamycin and erythromycin resistance was seen in 12.5% and 25%, respectively. Active surveillance and local knowledge of GBS epidemiology and antibiotic resistance has both patient and public health importance. Vaccine candidates are currently in their clinical phase of development.
