Insights

Campylobacter jejuni bacteremia is rare in children, primarily affecting immunocompromised individuals. High resistance to ciprofloxacin makes it unsuitable for empirical treatment, while erythromycin resistance remains low but requires monitoring.

Area of Science:

  • Pediatric Infectious Diseases
  • Microbiology
  • Antimicrobial Resistance

Background:

  • Invasive disease caused by Campylobacter species is infrequently reported.
  • Bloodstream infections are typically seen in immunocompromised patients or those with severe underlying conditions.

Purpose of the Study:

  • To determine the incidence of Campylobacter jejuni bacteremia in pediatric patients.
  • To assess the antimicrobial susceptibility of C. jejuni to erythromycin and ciprofloxacin.

Main Methods:

  • Prospective study conducted from April 2010 to June 2012 at Hospital Niño Jesús, Madrid.
  • Campylobacter isolates identified using standard culture methods.
  • Antimicrobial susceptibility testing performed via disk diffusion method.

Main Results:

  • 171 Campylobacter isolates from 154 pediatric patients; 66% identified as C. jejuni.
  • C. jejuni bacteremia occurred in 1.34% of all bloodstream infections, exclusively in immunocompromised children.
  • High resistance to ciprofloxacin (88%) and low resistance to erythromycin (5%) were observed.

Conclusions:

  • Campylobacter species are uncommon causes of bloodstream infections in children, predominantly affecting those with immune deficiencies.
  • Empirical use of fluoroquinolones for Campylobacter infections is not recommended due to high resistance rates.
  • Continued surveillance of erythromycin resistance in Campylobacter is advisable.

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...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
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,...
