Insights

Exclusive breastfeeding significantly reduces the risk of Giardia lamblia infections in infants. This protective effect lessens both asymptomatic and symptomatic Giardia infections and their associated symptoms.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Public Health

Background:

  • Giardia lamblia is a common protozoan parasite causing enteric infections in infants.
  • Understanding risk factors for Giardia infection is crucial for prevention strategies in endemic areas.

Purpose of the Study:

  • To document Giardia lamblia infection in Egyptian infants.
  • To determine the protective effect of breast-feeding against Giardia infections.

Main Methods:

  • A longitudinal study followed 152 infants from birth to 1 year in rural Egypt.
  • Data collected included Giardia infection status (asymptomatic/symptomatic) and feeding practices.
  • Statistical analysis used odds ratios and relative risks to assess the impact of breast-feeding.

Main Results:

  • Asymptomatic Giardia infections averaged 4.5 episodes per child-year and persisted for a mean of 7.18 weeks.
  • Exclusively breast-fed infants showed a reduced risk of asymptomatic (OR=0.66) and symptomatic (RR=0.50) infections.
  • Breast-fed infants experienced fewer symptoms like mucus in stool, loss of appetite, and abdominal tenderness.

Conclusions:

  • Exclusive breast-feeding is an effective preventive measure against Giardia lamblia infections in infants.
  • Promoting breast-feeding is recommended in regions with high endemicity of Giardia.
  • Breast-feeding mitigates the severity and incidence of Giardia infections and associated clinical manifestations.

Transcytosis of IgG01:15

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Giardiasis01:12

Giardiasis

Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
