Insights

A study in Kolkata, India, found 131 Vibrio fluvialis strains in diarrhea patients. Many strains carried virulence genes, offering insights into Vibrio fluvialis pathogenicity.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Gastroenterology

Background:

  • Diarrheal diseases remain a significant global health concern.
  • Vibrio species are known etiological agents of gastroenteritis.
  • The specific role of Vibrio fluvialis in diarrheal illness requires further elucidation.

Purpose of the Study:

  • To identify and characterize Vibrio fluvialis isolates from patients with diarrhea in Kolkata, India.
  • To investigate the prevalence of V. fluvialis as a sole pathogen in diarrheal cases.
  • To explore potential virulence factors associated with V. fluvialis pathogenicity.

Main Methods:

  • Bacterial isolation and identification of Vibrio species from stool samples.
  • Molecular detection of virulence genes, including hemolysin and metalloprotease.
  • Clinical data review to determine V. fluvialis as the sole identified pathogen.

Main Results:

  • 131 strains of Vibrio fluvialis were identified from 400 nonagglutinating Vibrio spp. isolates.
  • Vibrio fluvialis was the sole pathogen in 43 of the diarrheal cases.
  • The majority of V. fluvialis strains harbored genes for hemolysin and metalloprotease.

Conclusions:

  • Vibrio fluvialis is a notable cause of diarrhea in Kolkata, India.
  • The presence of hemolysin and metalloprotease genes suggests their contribution to V. fluvialis pathogenicity.
  • Further research is warranted to fully understand the mechanisms of V. fluvialis-associated disease.

Cholera01:25

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,...
Bacterial Gastroenteritis01:18

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...
Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Drugs for Treatment of Diarrhea-Predominant IBS

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
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,...
