    Insights

    Individuals with blood group O showed higher susceptibility to cholera, while those with blood group A were less susceptible. Further research is needed to understand host susceptibility in cholera and similar diarrheal diseases.

    Area of Science:

    • Infectious Diseases
    • Human Genetics
    • Epidemiology

    Background:

    • Cholera remains a significant public health concern, particularly in regions with limited sanitation.
    • Understanding host factors influencing susceptibility is crucial for effective prevention and treatment strategies.

    Purpose of the Study:

    • To investigate the association between ABO blood groups and susceptibility to cholera.
    • To compare blood group distribution in cholera patients with the general population.

    Main Methods:

    • Blood samples were collected from 87 confirmed cholera cases and 33 individuals with cholera-like diarrhea.
    • ABO blood group typing was performed for all participants.
    • Blood group frequencies were compared to the distribution in the general Philippine population.

    Main Results:

    • A higher prevalence of blood group O was observed among cholera patients compared to the general population.
    • Individuals with blood group A showed a lower prevalence in the cholera patient group.
    • A statistically significant difference in blood group distribution was noted.

    Conclusions:

    • ABO blood group may play a role in host susceptibility to cholera.
    • Blood group O might be associated with increased risk, while blood group A may confer some protection.
    • Further studies are recommended to elucidate the mechanisms underlying this association and its implications for enterotoxigenic diarrheal diseases.

    Blood Types

    Human blood is classified into different types based on the presence of antigens on the red blood cell's surface and antibodies in the plasma. Proper identification of blood type is essential for successful blood transfusion. The International Society of Blood Transfusion has identified 38 human blood types based on the surface antigens on the red blood cells. The most common types are ABO, Rh, and MNS blood types.

    Blood Transfusion and Agglutination

    Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
    History
    The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

    The ABO Blood Group

    The ABO blood group system is a critical element of transfusion medicine, essential for determining blood compatibility in transfusions and organ transplants. It is based on specific antigens, or agglutinogens, present on the surface of red blood cells (RBCs) and corresponding antibodies, or agglutinins, in the blood plasma.
    Antigens in the ABO Blood Group System
    Antigens are substances that can trigger an immune response, leading to the production of antibodies. In the ABO blood group system,...
    Blood Typing01:10

    Blood Typing

    Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
    Antigens are protein molecules that reside on the surface of red blood cells (RBCs). The ABO and Rh blood typing systems target antigens A,...

    Blood Transfusion

    Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
    Blood Transfusion Overview
    A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...
    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,...
