BASIC CONCEPTS
This type of infection describes cholera as affecting only humans.
What is an anthroponotic infection?
Vibrio cholerae is this type of bacteria by Gram stain.
What is Gram-negative?
These individuals are the primary source of infection.
Who are infected patients?
This part of the GI tract is mainly affected.
What is the small intestine?
This is the most important life-saving treatment.
What is rehydration therapy?
This classic stool appearance is described as “rice broth.”
What is watery diarrhea?
This is the shape of Vibrio cholerae.
What is a curved rod (comma-shaped)?
This is the most common transmission vehicle.
What is contaminated water?
This toxin is responsible for cholera symptoms.
What is cholera toxin?
This oral solution is recommended by WHO.
What is oral rehydration solution (ORS / Oralit)?
This major physiological disturbance defines severe cholera.
What is dehydration (water-electrolyte imbalance)?
In liquid, vibrios appear arranged like this pattern.
What is a “school of fish”?
These individuals have no symptoms but still spread cholera.
Who are asymptomatic carriers?
This intracellular molecule increases due to toxin activity.
What is cAMP?
This is the gold standard diagnostic method.
What is bacteriological culture?
These two clinical forms describe intestinal involvement in cholera.
What are enteritis and gastroenteritis?
These are the two main biovars of Vibrio cholerae.
What are Classical and El Tor?
These insects can mechanically transmit cholera.
What are flies?
This cellular system is activated by cholera toxin.
What is the adenylate cyclase system?
This rapid test uses labeled antibodies to detect vibrios.
What is immunofluorescence?
Cholera is classified under this type of disease due to its global risk.
What is a highly dangerous quarantine disease?
This structure enables motility and contributes to colonization.
What is a flagellum?
These individuals continue excreting vibrios for 2–4 weeks after illness.
Who are convalescents?
This molecular mechanism explains persistent secretion in cholera.
What is ADP-ribosylation of Gs protein leading to continuous cAMP production?
This prevention strategy has the greatest population-level impact.
What is ensuring safe water supply and proper sanitation?
