Abstract

Highlights: • Rectal and vaginal swab specimens were collected from pregnant women, and there was no significant difference in the proportions of group B Streptococcus isolation. • Combined vaginal and rectal swab cultures provide a higher isolation of group B Streptococcus. Abstract : Group B Streptococcus is a Gram-positive bacterium found in women. It causes high-risk mortality in pregnant women, newborns, and the elderly. This study aimed to compare group B Streptococcus (GBS/Streptococcus agalactiae) proportions from different collection sites (vaginal and rectal swabs). This was an analytic observational study with a hospital-based cross-sectional design. A total of 74 swabs were taken from 37 pregnant women at 35–37 weeks of gestation. Each participant provided a vaginal swab and a rectal swab, which were cultured in Todd Hewitt broth, blood agar, and CHROMagar. The specimens were subsequently identified using the VITEK 2 system. The GBS isolation percentages from the vaginal and rectal swab specimens were determined to be 13.5% and 8.1%, respectively. The McNemar test had a result of 0.697, and the Cohen's kappa test had a result of 0.165. To conclude, there was no significant difference in GBS isolation proportions between the vaginal and rectal swab cultures. Combined vaginal and rectal swab cultures were required to increase GBS isolation from pregnant women.

Abstract

Highlights: • ESBL frequency in women was higher than in men. • Catheter use in patients with urinary tract infections and recurrent urinary tract infections has four times the risk of ESBL caused by Escherichia coli bacteria • ESBL-producing E.coli bacteria are resistant to amoxicillin-clavulanic, ceftazidime, aztreonam, and ceftriaxone. Abstract: The incidence of urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL) producing Escherichia coli (E. coli) bacteria has become a global problem and has increased in recent years. The purpose of this study was to analyze the risk factors for the incidence of UTI in inpatients at Dr. Soetomo General Academic Hospital Surabaya. This research was an analytic descriptive study. Specimens were sent to the Clinical Microbiology Laboratory using sterile containers and processed according to standard laboratory procedures. It resulted in ESBL-producing E. coli that were used as a case group and non ESBL-producing E. coli as a control group. The identification and testing of antibiotic susceptibility were carried out using the BD Phoenixâ„¢ Automated Microbiology System. Ninety-four bacterial isolates were collected, consisting of 54 (57.4%) ESBL-producing E. coli bacteria and 40 (42.6%) non ESBL-producing E. coli bacteria. Recurrent UTIs (OR = 4.31; ρ =0.002; 95% CI = 1.68-11.04) and catheter use (ρ = 0.049; OR = 4.250; 95% CI = 1.050-17.210) were used as independent risk factors caused by ESBL-producing E. coli bacteria. Recurrent UTIs and catheter use were dependent risk factors caused by ESBL-producing E. coli bacteria.

Abstract

Highlight:• Bacteriologically for colonization of ESBL producing Enterobacteriaceae in cockroaches (Periplaneta americana) were analyzed. • The prevalence of ESBL producing bacteria among cockroaches in hospitals is bigger than in households. Abstract: Cockroach (Periplaneta americana) is one of the vectors in the environment that can transmit disease. Cockroaches can act as potential mechanical vectors of antibiotic resistant bacteria. Enterobacteriaceae is a gram-negative bacteria that has natural habitats in the digestive tract of humans and animals. Enterobacteriaceae that produce Extended Spectrum β-lactamases (ESBLs) have emerged as major pathogens in hospitals. The study analyzed the prevalence of ESBL producing bacteria in cockroaches that lived in hospitals and residential homes. In this study, a total of 200 cockroaches consisting of 100 cockroaches from the hospital environment and 100 cockroaches from the residential environment were analyzed bacteriologically for colonization of ESBL producing Enterobacteriaceae. The specimen of the alimentary tract was taken and sub-cultured in MacConkey agar supplemented with cefotaxime 2 ug/ml. Growth colonies were suggested as an ESBL-producing bacteria, then were confirmed as ESBL producers by the Double Disk Synergy Test (DDST). The ESBL gene was detected by Polymerase Chain Reaction (PCR). Among 100 household cockroach samples, 14 (14%) were identified as ESBL producers, while 100 hospital cockroaches were 26 (26%) positive ESBL. The ESBL gene, in hospital cockroach were identified of CTXM 19 (19%), SHV 7 (7%), and not any TEM gene, while among household cockroaches were identified CTXM 2 (2%), SHV 11 (11%), and also not detected TEM ESBL gene. Among ESBL genes, only the CTXM gene was significantly different between household and hospital cockroaches.
