Reagent strip testing for antenatal screening and first meaningful of asymptomatic bacteriuria in pregnant women.

Objective: To evaluate the diagnostic performance of reagent strip test as a screening test for asymptomatic bacteriuria (ABU) in pregnant women.

Material And Method: Three hundred and sixty asymptomatic pregnant women who attended their first antenatal appointment at Rajavithi Hospital from August 1st to October 31st, 2005 were enrolled Those with symptoms of urinary tract infection within one month, those who had been prescribed antibiotics during the previous 7 days, and those with medical or obstetric complications, vaginal bleeding and a history of urinary tract diseases were excluded Urine specimens were collected by clean-catched midstream urine technique for urine dipstick and culture.

Comparison of combined vaginal-anorectal, vaginal and anorectal cultures in detecting of group B streptococci in pregnant women in labor.

Objective: To compare whether the Group B streptococcal culture detection rate from vaginal-anorectal cultures, vaginal, or anorectal are equivalent.

Material And Method: Cross-sectional descriptive study was performed on 320 pregnant women with a gestational age between 28-42 weeks presenting with labor pain, between October, 1 and 30, 2004 in Rajavithi Hospital. Anorectal and vaginal swab cultures were collected and cultured in Todd Hewitt broth with 15 microg/ ml nalidixic acid and 8 microg/ml gentamicin.

Risk factors related to group B streptococcal colonization in pregnant women in labor.

Material And Method: From the 1st-30th October 2004, at the Rajavithi Hospital, 320 pregnant women, who fulfilled the specified criteria, were selected for a cross-sectional descriptive study. Swabs were cultured from the lower vagina and anorectum for GBS using Todd-Hewitt broth with nalidixic acid 15 microg/ml and gentamicin 8 microg/ml only.

Results: Colonization was present in 58 cases (18.

Comparison of media and antibiotic supplements for isolation of Helicobacter pylori from gastric biopsies.

Our objective was to improve the media and the antibiotic supplements in order to increase the detection rate of Helicobacter pylori from gastric biopsy specimens. For the primary isolation of H. pylori taken from gastric biopsies, we compared the efficacy of two media: Columbia blood agar (CBA, Difco); brain heart infusion agar (BHIA, Difco); and two antibiotic supplement sets--a commercial antibiotic supplement (SR147, Oxoid) and an in-house antibiotic supplement (IHS).
