Unravelling Streptococcus agalactiae: Serotype distribution, virulence factors, obstetrics history and clinical presentation correlations in tertiary care hospitals of the western province of Sri Lanka.

Purpose: This study investigated to detect serotypes and virulence genes of Group B Streptococcus (GBS) isolated from pregnant women.

Methods: Forty-five samples of GBS isolates from January to August 2019 at antenatal clinics of 4 teaching hospitals in Western Province, Sri Lanka were included. Isolated GBS were carried to identify 9 serotypes by multiplex PCR.

Antibiotic Sensitivity of Group B Streptococcus from Pregnant Mothers and Its Association with Resistance Genes.

Objective: This study assessed the antibiotic susceptibility and characterized antibiotic resistance genes of group B Streptococcus (GBS) isolates from selected tertiary care hospitals in Western Province, Sri Lanka.

Methods: A descriptive cross-sectional study was carried out to determine antibiotic sensitivity of GBS among 175 pregnant women of >35 weeks of gestation attending antenatal clinics in four teaching hospitals. Low vaginal and rectal swabs were collected separately, and GBS was identified by standard microbiological methods.

Biofilm formation and antibiotic resistance among Coagulase Negative Staphylococcus species isolated from central venous catheters of intensive care unit patients.

Purpose: This study was conducted to determine the biofilm formation of coagulase negative Staphylococcus species (CoNS) isolated from patients with catheter related blood stream infection (CRBSI) and colonized central venous catheters (CVC) and their antibiotic susceptibility patterns and in situ biofilm formation of CVC tips.

Methods: Eighty-two CoNS isolated from intensive care unit (ICU) patients with CRBSI (n ​= ​8) or colonized CVC (n ​= ​74) were included. Species identification and antibiotic susceptibility test were done.
