Insights

Yersinia enterocolitica infections are uncommon in Tehran children with acute diarrhea during summer. Atypical Yersinia species were identified, with similar antimicrobial resistance patterns observed in these cases.

Area of Science:

  • Microbiology
  • Pediatrics
  • Infectious Diseases

Background:

  • Acute diarrhea is a common pediatric illness.
  • Identifying causative agents is crucial for effective treatment.
  • Yersinia enterocolitica is a known enteric pathogen.

Purpose of the Study:

  • To determine the frequency of Yersinia enterocolitica infection in children with acute diarrhea in Tehran.
  • To identify co-infections with other common enteric pathogens.
  • To characterize the serotypes and antimicrobial resistance of isolated Yersinia species.

Main Methods:

  • Stool samples from 300 children (0-12 years) with acute diarrhea were analyzed.
  • Culture and serotyping were performed for Yersinia species and other enteric organisms.
  • Antimicrobial resistance patterns were determined for Yersinia isolates.

Main Results:

  • Yersinia species were detected in 2.7% of cases.
  • Atypical Yersinia species (Y. intermedia, Y. frederiksenii) were isolated, not common serotypes O:3 or O:9.
  • Enteropathogenic E. coli (5.7%), Shigella spp. (3.0%), and Salmonella spp. (2.0%) were also identified.
  • All Y. enterocolitica isolates exhibited similar antimicrobial resistance.

Conclusions:

  • Yersinia spp. infections are infrequent in Tehran children during summer months.
  • Atypical Yersinia strains may play a role in pediatric diarrhea in this region.
  • Understanding local pathogen prevalence and resistance is vital for public health.

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...
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...
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,...

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
