Insights

Genital mycoplasma species, Ureaplasma parvum and Ureaplasma urealyticum, are linked to preterm birth and infant morbidities. These common pathogens affect nearly half of very preterm infants, contributing to serious health issues.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatology
  • Infectious Diseases

Background:

  • Genital mycoplasma species, Ureaplasma parvum and Ureaplasma urealyticum, are frequently found in amniotic fluid and placentas.
  • These bacteria are associated with adverse pregnancy outcomes, including preterm birth and neonatal complications.

Purpose of the Study:

  • To review epidemiological and experimental evidence linking perinatal Ureaplasma exposure to morbidities of prematurity.
  • To highlight the prevalence of Ureaplasma in preterm infants and its role as a common pathogen.

Main Methods:

  • Review of epidemiological studies.
  • Analysis of experimental evidence.
  • Examination of clinical data from preterm infants.

Main Results:

  • Ureaplasma species are the most common organisms in infected amniotic fluid and placentas.
  • Nearly 50% of preterm infants (<32 weeks gestation) in the institution are Ureaplasma-positive in various body compartments.
  • Evidence links perinatal Ureaplasma exposure to bronchopulmonary dysplasia, intraventricular hemorrhage, and necrotizing enterocolitis.

Conclusions:

  • Ureaplasma species are significant contributors to adverse pregnancy outcomes and neonatal morbidities.
  • These pathogens represent a major threat to the health of preterm infants.
  • Further research is warranted to understand and mitigate the impact of Ureaplasma in perinatal infections.

Development of the Oral Microbiota01:28

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,...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Bacterial Phylum Chlamydiae01:29

Bacterial Phylum Chlamydiae

The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic of...

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
Neurulation01:30

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
