Deadly Genetics of Cholera

Experts discover the deadly genetics of cholera, which could be key to its prevention


Experts have used a cutting-edge computational approach to discover the genetic factors that make the bacteria behind cholera so dangerous—which could be key to preventing this deadly disease.

The breakthrough study, published in Nature Communications, is led by Professor Tania Dottorini from the University of Nottingham, in collaboration with Bangladesh's Institute of Epidemiology, Disease Control and Research (IEDCR), International Center for Diarrheal Disease Research, Bangladesh, and North South University.

The innovative research combines machine learning, genomics, genome-scale metabolic modeling (GSMM), and 3D structural analysis to uncover the genetic secrets of Vibrio cholerae—the bacteria behind cholera.

Cholera is a deadly diarrheal disease that continues to threaten millions worldwide, with up to 4 million cases and as many as 143,000 deaths each year. In Bangladesh alone, where cholera is a persistent danger, 66 million people are at risk, with more than 100,000 cases and 4,500 deaths annually.

Vibrio cholerae, is evolving in ways that make the disease more severe and harder to control, but until now, scientists have struggled to pinpoint the exact genetic factors driving these changes.

There is even less knowledge about the genomic traits responsible for the severity of cholera resulting from these lineages. About 1 in 5 people with cholera will experience a severe condition owing to a combination of symptoms (primarily diarrhea, vomiting, and dehydration).

In this new study, the U.K.-Bangladeshi research team analyzed bacterial samples from cholera patients across six regions in Bangladesh, collected between 2015 and 2021. They identified a set of unique genes and mutations in the most recent and dominant strain of Vibrio cholerae responsible for the devastating 2022 outbreak.

These genetic traits are linked to the bacteria's ability to cause severe symptoms like prolonged diarrhea, intense abdominal pain, vomiting, and dehydration—symptoms that can lead to death in severe cases.

Professor Dottorini said, "By identifying the key genetic factors that drive both the transmission and severity of cholera, we've taken a significant step toward developing more effective treatments and targeted interventions. This could save thousands of lives, not just in Bangladesh, but globally."

The findings of the study also revealed that some of these disease-causing traits overlap with those that help the bacteria spread more easily. The findings show how these genetic factors enable Vibrio cholerae to survive in the human gut, making it more resilient to environmental stress and more efficient at causing disease. This research highlights the complex interactions between the bacteria's genetic makeup and its ability to cause severe illness.

This new computational framework is a major step forward in the fight against cholera. By identifying the key genetic factors that make Vibrio cholerae more dangerous, scientists can develop better treatments and more targeted strategies to control and prevent future outbreaks. This breakthrough offers new hope for improving public health in Bangladesh and potentially saving countless lives worldwide.

Dr. Dottorini adds, "Our findings open the door to a new era of cholera research, where we can develop tools to predict and potentially prevent severe outbreaks before they occur. The ultimate goal is to translate these insights into real-world solutions that protect vulnerable populations.

"This breakthrough was only possible through the close collaboration between our U.K. and Bangladeshi partners. Together, we've combined cutting-edge computational tools with local expertise to tackle one of the most pressing public health challenges."

Genetics role in ovarian cancer

The Medical Minute: Genetics play big role in ovarian cancer In 2024, about 19,680 women in the United States will receive a new diagnosis of ovarian cancer and 12,740 women will die from the disease, said Dr. Shaina Bruce , a gynecologic oncologist at Penn State Cancer Institute . The median age of all patients who develop ovarian cancer is 63. Historically, women at increased risk for ovarian cancer are recommended to have their fallopian tubes and ovaries removed when they have completed having children. Taking that step to protect themselves comes at a heavy price ― surgical menopause. But Bruce said medical science is catching up with ovarian cancer. Studies could lead to new methods for preventative care and the surgery needed to lower risk may be easier than it once was. Below, during Gynecologic Cancer Awareness Month, Bruce discusses the disease and why acting to reduce your risk is worth it. What’s the connection between heredity and ovarian cancer? About 25% of all cases of ...

Multifactorial Genetic Conditions

Multifactorial Genetic Conditions Multifactorial genetic conditions are disorders caused by the combined effects of multiple genes and environmental factors , rather than a single gene mutation . These conditions do not follow classic Mendelian inheritance patterns and instead result from complex gene–environment interactions . Factors such as lifestyle, nutrition, infections, stress, and exposure to toxins can significantly influence disease onset and severity in genetically susceptible individuals. Common examples include diabetes, cardiovascular diseases , neural tube defects, asthma, and many neuropsychiatric disorders. Understanding multifactorial inheritance is essential for risk prediction, preventive medicine, and personalized healthcare strategies. Multifactorial inheritance, polygenic traits, gene–environment interaction, complex diseases, genetic susceptibility, environmental risk factors, non-Mendelian inheritance, disease predisposition, polygenic risk score, precision ...

X chromosome

Gene on the X chromosome may help explain high multiple sclerosis rates in women Brain inflammation may be fueled by a gene on the X chromosome, a new study in mice suggests. And in female mice, who carry two X chromosomes, a diabetes drug called metformin may work to counteract that inflammation. If these findings bear out in later studies, they could help to unravel the long-standing mystery of why women, who have two copies of this inflammation-driving gene, are more prone to certain autoimmune diseases, particularly after menopause. A disparity between the sexes Our bodies are patrolled by immune cells that provide protection against bacteria and viruses, but sometimes, these defenses turn on us. In the autoimmune disorder multiple sclerosis (MS), for instance, the immune system attacks myelin, the fatty insulation surrounding the nerve fibers in the brain and spinal cord. This leads to symptoms such as muscle weakness and difficulty walking, as well issues with memory and thinking...
