Summary
Plesiomonas shigelloides infection alone rarely causes diarrhea. However, co-infection with rotavirus significantly increases diarrheal risk in rural communities, highlighting the importance of identifying co-infections.
Area of Science:
- Infectious Diseases
- Public Health
- Microbiology
Background:
- Diarrheal diseases pose a significant public health challenge globally.
- Plesiomonas shigelloides is a recognized enteric pathogen, but its role in diarrheal illness requires further clarification.
- Co-infections with multiple enteric pathogens are common and can complicate disease presentation.
Purpose of the Study:
- To investigate the association between Plesiomonas shigelloides infection and diarrheal risk.
- To determine the impact of co-infection with other common enteric pathogens on diarrheal outcomes.
- To assess the epidemiological significance of P. shigelloides in a rural Ecuadorian population.
Main Methods:
- A longitudinal study was conducted in rural northwestern Ecuador from 2004 to 2008.
- Stool samples were collected and analyzed for the presence of enteric pathogens, including Plesiomonas shigelloides and rotavirus.
- Diarrheal episodes were monitored and statistically analyzed in relation to pathogen detection.
Main Results:
- Single infections with Plesiomonas shigelloides showed minimal association with diarrhea.
- A significant association was observed between co-infection with P. shigelloides and rotavirus and the occurrence of diarrhea.
- Rotavirus emerged as a key factor in diarrheal episodes, particularly when co-occurring with P. shigelloides.
Conclusions:
- Plesiomonas shigelloides is unlikely to be a major cause of diarrhea as a sole pathogen.
- Co-infection with rotavirus is a critical determinant of diarrheal risk in the studied population.
- Public health strategies should consider the role of co-infections in managing diarrheal diseases.

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...
01:25Cholera
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,...
01:23Investigation 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...
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,...
01:15Diversity of Protists I
Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...
