Summary
Salmonella enteritis is a significant health issue, especially in developing nations. This study identified common Salmonella serotypes in Yanbu, Saudi Arabia, finding S. typhimurium most prevalent and norfloxacin effective against resistant strains.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Salmonella enteritis causes significant morbidity and mortality globally, particularly in developing countries.
- Salmonella serotype prevalence varies geographically and temporally.
- Understanding local Salmonella epidemiology is crucial for effective public health interventions.
Purpose of the Study:
- To determine the prevalence of different Salmonella serotypes in the Yanbu area, Saudi Arabia.
- To identify the most common Salmonella serotypes causing gastroenteritis in the region.
- To evaluate the antibiotic susceptibility patterns of isolated Salmonella strains.
Main Methods:
- Analysis of 136 stool cultures from patients with gastroenteritis at Royal Commission Hospital, Yanbu.
- Identification and serotyping of Salmonella isolates.
- Antibiogram testing to assess susceptibility to various antibiotics, including norfloxacin.
Main Results:
- Thirty-one Salmonella isolates were identified, belonging to 15 different serotypes, all of the gastroenteric, diarrhoeagenic, non-invasive group.
- The most common serotype was Salmonella typhimurium (45.16%), followed by Salmonella enteritidis (9.62%) and Salmonella virchow (6.46%).
- All isolates were sensitive to norfloxacin, with varying resistance to chloramphenicol, ampicillin, and trimethoprim.
Conclusions:
- Salmonella typhimurium is the predominant serotype causing enteritis in the Yanbu area.
- Norfloxacin demonstrated high efficacy against resistant Salmonella strains with a favorable safety profile.
- These findings highlight the importance of local surveillance of Salmonella serotypes and antibiotic resistance patterns.

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...
01:30Reservoir 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,...
01:18Bacterial 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...

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,...
