Summary
Vibrio parahaemolyticus caused 8.7% of bacterial gastroenteritis during Senegal's 2004-2005 cholera outbreak. Most cases were foodborne and family-transmitted, with patients recovering quickly after rehydration and doxycycline treatment.
Area of Science:
- Epidemiology
- Microbiology
- Infectious Diseases
Background:
- Senegal experienced a cholera outbreak in 2004-2005.
- Gastroenteritis is a significant public health concern.
Purpose of the Study:
- To describe the epidemiological, clinical, and bacteriological features of Vibrio parahaemolyticus gastroenteritis.
- To understand the role of V. parahaemolyticus during a cholera outbreak.
Main Methods:
- Retrospective study of data from Dakar Fann Hospital (October 2004 - December 2005).
- Diagnosis of V. parahaemolyticus via stool culture.
- Analysis of patient demographics, clinical presentation, and treatment outcomes.
Main Results:
- Thirty-five cases of V. parahaemolyticus gastroenteritis were identified (8.7% of bacterial gastroenteritis).
- Median age was 26 years, with a M/F ratio of 1.5; most cases originated from Dakar.
- Foodborne and intrafamilial transmission were suspected; common symptoms included diarrhea, vomiting, and dehydration.
- All isolates were susceptible to common antibiotics; treatment with rehydration and doxycycline resulted in favorable outcomes.
Conclusions:
- Vibrio parahaemolyticus was a notable cause of gastroenteritis during the 2004-2005 cholera outbreak in Senegal.
- Prompt treatment with rehydration and doxycycline led to full recovery.

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,...
01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
