Vibrio cholerae Invasion Dynamics of the Chironomid Host Are Strongly Influenced by Aquatic Cell Density and Can Vary by Strain

Cholera has been a human scourge since the early 1800s and remains a global public health challenge, caused by the toxigenic strains of the bacterium Vibrio cholerae. In its aquatic reservoirs, V. cholerae has been shown to live in association with various arthropod hosts, including the chironomids, a diverse insect family commonly found in wet and semiwet habitats.

Cholera bacteria colonize Haitian rivers, evolve

UF researchers uncovered evidence that the bacteria which cause cholera, Vibrio cholerae, have established an aquatic reservoir in Haitian waterways where they are now adapting and evolving. This marks the first time the pathogenic bacteria are known to have a reservoir outside of the Bay of Bengal, which is traditionally viewed as their home.

Nelson Lab Teaches COTS Course in Haiti

Nelson lab travels to Haiti to educate students at the Université d’État d’Haiti Faculté de Médicine et de Pharmacie in Port au Prince on water-borne diseases.

Eliminating Cholera transmission in Haiti

On October 13th and 14th, 2016, the Minister of Health and Population of Haiti, Dr. Daphnee Benoit, convened an expert panel to consult on the control of cholera in Haiti with specific reference to the use of vaccines in the aftermath of Hurricane Mathew; the consultation resulted in the following consensus.

Cameroon’s cholera outbreaks vary by climate region

For more than four decades, cholera has recurred in Cameroon, affecting tens of thousands of people a year. Most recently, the West African country was one of four that had a death rate of more than five percent from the bacterial disease, exceeding the World Health Organization’s target of less than one percent. Now, researchers have discovered one reason Cameroon has struggled to control the disease. Cholera follows different, distinct outbreak patterns in different climate subzones of the large country, the researchers reported in PLOS Neglected Tropical Diseases.
