Insights

This study investigated bacterial pathogens in rectal swabs from young children in Iran. Yersinia spp. and Campylobacter spp. were found to be significant causes of diarrhea, with seasonal variations in isolation rates.

Area of Science:

  • Pediatric infectious diseases
  • Microbiology
  • Public health

Background:

  • Diarrheal diseases are a major cause of morbidity and mortality in children under five.
  • Identifying causative bacterial pathogens is crucial for effective treatment and prevention strategies.

Purpose of the Study:

  • To determine the prevalence of various bacterial enteric pathogens in young children with diarrhea.
  • To investigate the seasonal distribution of these pathogens.

Main Methods:

  • Rectal swabs were collected from 1600 children under five years old.
  • Specimens were cultured and examined for bacterial pathogens including Escherichia coli, Shigella, Salmonella, Campylobacter, and Yersinia.

Main Results:

  • Enteropathogenic Escherichia coli had the highest isolation rate (6.8%), followed by Shigella spp. (3.4%) and Salmonella spp. (2.9%).
  • Campylobacter spp. (0.9%) and Yersinia spp. (0.7%) were also isolated.
  • Most pathogens were prevalent in summer, but Yersinia spp. peaked in spring.

Conclusions:

  • Yersinia spp. and Campylobacter spp. are significant etiological agents in pediatric diarrhea in the region.
  • Understanding seasonal patterns of bacterial pathogens can aid in public health interventions.

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...
Reservoir of Infection01:30

Reservoir of Infection

Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...
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,...
Investigation of Disease Outbreaks01:23

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
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...
