Insights

Group B Streptococcus (GBS) carriage in pregnant women was 9.39% at Posadas Hospital. Most GBS isolates were susceptible to penicillin, erythromycin, and clindamycin, with low resistance observed.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Obstetrics & Gynecology

Context:

  • Group B Streptococcus (GBS) is a leading cause of neonatal infections via vertical transmission.
  • GBS also causes infections in pregnant women and immunocompromised adults.
  • Understanding GBS carriage and resistance patterns in pregnant populations is crucial for infection control.

Purpose:

  • To determine the prevalence of GBS carriage among pregnant women attending Posadas Hospital.
  • To analyze the antimicrobial susceptibility patterns of GBS isolates to penicillin, erythromycin, and clindamycin.

Summary:

  • A study of 1203 pregnant women found a GBS carriage prevalence of 9.39% (113 isolates).
  • Antimicrobial susceptibility testing on 87 GBS isolates revealed universal susceptibility to penicillin.
  • Two isolates exhibited resistance to erythromycin and clindamycin, indicating a constitutive MLS mechanism.

Impact:

  • Highlights the importance of GBS screening in pregnant women.
  • Provides data on GBS antimicrobial resistance, particularly relevant for penicillin-allergic individuals.
  • Informs clinical management decisions regarding GBS infections and antibiotic choices during pregnancy.

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
