Invasive Group B Streptococcus Disease Burden and Its Antimicrobial Resistance in Malaysia Among Non-pregnant Adults.

Invasive Group B Streptococcus Disease Burden and Its Antimicrobial Resistance in Malaysia Among Non-pregnant Adults: a Prospective Observational Protocol Study

Group B Streptococcus (GBS) infection is a potential aetiology of meningitis and septicemia in neonates, pregnant women and non-pregnant adults. Because the GBS disease burden is unknown in Malaysia, it is unlikely to receive much attention. This study aims to determine the prevalence of group B streptococcus isolated from non-pregnant adults, the Incidence, case-fatality ratio, antimicrobial susceptibility patterns, serotyping, genotyping and detection of the GBS virulence and pili genes from six major hospitals in Peninsular Malaysia.

This multicentre, prospective, observational study will be conducted in six major tertiary hospitals in Malaysia among Non-Pregnant Adults. At the same time, a retrospective study will be conducted on the selected hospitals to determine GBS strains and data. GBS isolates will be subjected to phenotyping, serotyping using Multiplex PCR, antimicrobial susceptibility testing and detection of GBS virulence and pilus genes. Seven housekeeping genes will be sequenced internally to perform multi-locus sequence typing (MLST). Findings from the study will contribute to improving clinical practice to diagnose and prevent GBS disease on time. The prudent use of antibiotics will be encouraged by monitoring antimicrobial resistance.

Inclusion Criteria:

• Non-pregnant adult patients
• patients with group B streptococcus infection
• The clinical samples isolated from sterile sites (blood, cerebrospinal fluid, internal tissue, pus aspirate, peritoneal dialysis fluid, bone biopsy, skin biopsy and bone marrow).

Exclusion Criteria:

• Repeated group B streptococcus that is isolated from the same patients in the same admission
• Non-sterile site isolates (Urine, Vaginal swab)
