Insights

Rotavirus was the primary cause of acute diarrhea in Colombian children, with bacterial and parasitic co-infections also significant. This study identified key enteric pathogens affecting infants and young children.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Microbiology

Background:

  • Acute diarrhea remains a major health concern in young children globally.
  • Understanding the specific causative agents is crucial for effective treatment and prevention strategies.

Purpose of the Study:

  • To determine the etiology of acute diarrhea in young children and infants in Cartagena and Sincelejo, Colombia.
  • To identify the prevalence of various enteric pathogens, including viruses, bacteria, and parasites.

Main Methods:

  • Analysis of 253 stool samples from children with acute diarrhea.
  • Identification of enteric pathogens using microbiological and parasitological techniques.

Main Results:

  • Rotavirus type A was the most frequent pathogen (36.6%), particularly in infants under 12 months.
  • Bacterial pathogens included Salmonella spp. (9.0%) and Shigella spp. (8.0%).
  • Parasitic infections were also common, with Entamoeba hystolitica (10%) and Giardia lamblia (4%).
  • Mixed infections occurred in 37.9% of patients, and 18.6% had concurrent parasitic infections.
  • The study noted the first report of Providencia alcalifaciens associated with infantile diarrhea in Colombia and the regional debut of E. coli O157:H7 and Y. enterocolitica.

Conclusions:

  • Rotavirus is the leading cause of acute diarrhea in this Colombian pediatric population.
  • Bacterial and parasitic co-infections are prevalent and require consideration in diagnosis and management.
  • The findings highlight the importance of regional surveillance for emerging and re-emerging enteric pathogens.

Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Cholera01:25

Cholera

Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

Drugs for Treatment of Diarrhea-Predominant IBS

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...
