Summary
Salmonella gastroenteritis (GE) is common in Portuguese children, particularly in rural areas during warmer months. Salmonella enteritidis and Salmonella typhimurium were the most frequent serotypes identified, often linked to eggs and non-potable water.
Area of Science:
- Pediatric Infectious Diseases
- Microbiology
- Epidemiology
Context:
- Gastroenteritis (GE) caused by Salmonella is a significant childhood illness in Portugal.
- Approximately 456 cases are reported annually, with 82% affecting children under fifteen.
- A high admission rate for Salmonella GE was observed in a level two hospital setting.
Purpose:
- To conduct a clinical and laboratorial characterization of pediatric patients with Salmonella GE admitted to a hospital.
- To analyze epidemiological data, including serotypes, age distribution, seasonality, and potential sources of infection.
Summary:
- A retrospective study identified 218 cases of Salmonella GE (2.66%) among 8195 GE admissions between 2005 and 2009.
- Salmonella enteritidis (49.1%) and Salmonella typhimurium (29.8%) were the predominant serotypes.
- Infections peaked between May and October, with associations noted between S. enteritidis and summer, and S. typhimurium and spring. Eggs and non-potable water were implicated food items.
Impact:
- The study highlights the high prevalence of Salmonella GE in a rural pediatric population and its significant impact.
- Findings underscore the importance of age-specific serotype distribution and seasonal patterns in Salmonella infections.
- Understanding these factors can inform public health interventions and prevention strategies for childhood gastroenteritis.

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 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,...
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 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...
Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
