NewsBacterial hitchhikers can give their hosts super strength
Molecular hitchhikers living within bacteria can make their hosts extra resistant to medical treatment by corralling them into tightly packed groups. The study introduces a previously unknown avenue through which bacterial infections can become more difficult to treat.

NewsA bacterial toxin can counteract colorectal cancer growth
A toxin secreted by cholera bacteria can inhibit the growth of colorectal cancer without causing any measurable damage to the body. Systemic administration of the purified bacterial substance changes the immune microenvironment in tumours.

NewsA new study reveals how cholera virulence is activated
A new study provides a long-sought structural explanation of the regulatory cascade that allows Vibrio cholerae to colonize the human gut and produce the cholera toxin that causes life-threatening diarrhea.

NewsCholera vaccine completes phase 1 trial
A clinical trial shows promising results for PanChol, a single-dose oral vaccine aimed at the up to 4 million annual cholera cases worldwide.

NewsSugar transporter discovery offers promising avenue for improving antibiotic efficacy
Scientists have recently demonstrated that aminoglycosides enter bacteria by using sugar transporters. They have also successfully doubled the number of transporters, even in the most resistant Escherichia coli strains, thus improving antibiotics’ penetration rate and efficacy.

NewsStudy shows mucus contains molecules that block Salmonella infection
Researchers have identified mucins that defend against Salmonella and other bacteria that cause diarrhea. They now hope to mimic this defense system to create synthetic mucins that could help prevent or treat illness in soldiers or other people at risk of exposure to Salmonella.

NewsNew mechanisms for bacterial motility and DNA transfer between bacteria decoded
Scientists have discovered a new family of signaling proteins, widespread in the bacterial kingdom and contributing to regulating bacterial motility and DNA uptake mechanisms.

NewsCholera vaccination campaign launched in Darfur to protect over 1.8 million people
A cholera vaccination campaign kicked off on 21 September 2025 in South Darfur, marking the start of a campaign that aims to reach 1.86 million people aged one year and older with oral vaccines in response to the ongoing outbreak.

NewsAn oral cholera vaccination campaign aims to reach more than 2.6 million people in Sudan’s Khartoum State
A 10-day reactive oral cholera vaccination campaign, launched on 10 June in 5 localities in Sudan’s Khartoum State, aims to protect more than 2.6 million people aged 1 year and above from cholera infection, interrupt transmission and help contain the cholera outbreak.

NewsScientists uncover how certain cholera strains are so successful at evading phage attacks
A new study shows that a virulent lineage of cholera acquired multiple distinct bacterial immune systems that have protected it from diverse types of phages. This defense may have contributed to the massive scale of the Latin American epidemic.

NewsPatients with multi drug-resistant cholera in Europe linked to exposure to contaminated holy water from Ethiopia
Exposure to holy water from Ethiopia has recently been linked to several cases of cholera in the UK and Germany with a multidrug-resistant Vibrio cholerae strain, according to a new study.

NewsSophisticated early warning system: How bacteria respond to threats
Recent research has found that exogenous petidoglycan fragments of Vibrio cholerae and other multidrug-resistant pathogens are able to trigger 3D biofilm formation as an universial danger response.

NewsBad bacteria can trigger painful gut contractions; new research shows how
After a meal of questionable seafood or a few sips of contaminated water, bad bacteria can send your digestive tract into overdrive. Your intestines spasm and contract, efficiently expelling everything in the gut. Source: Parthasarathy Lab and Guillemin Lab Immune cells (magenta) and cells expressing a reporter of ...

NewsFrom Yemen to Mayotte, the spread of a highly drug-resistant cholera strain
Scientists have revealed the spread of a highly drug-resistant cholera strain. The strain is resistant to ten antibiotics – including azithromycin and ciprofloxacin, two of the three recommended for treating cholera – and was identified for the first time in Yemen in 2018-2019.

NewsBacteria thrive by playing nice before going their own way
A study tackles the question of how multiple bacterial species coexist in biofilms.

NewsBacterial contamination and microplastics threaten Colombia’s largest and most productive coastal lagoon
A study warns of the presence of potentially pathogenic bacteria in microplastics extracted from water, sediments and the digestive tract of fish in the Ciénaga Grande de Santa Marta, the largest and most productive coastal lagoon system in the Colombian Caribbean.

NewsRole of hydrogen sulfide in the expression of iron uptake genes is unveiled
Researchers have established the role of YgaV, a hydrogen sulfide dependent transcription factor, in regulating iron uptake dynamics in Escherichia coli.

NewsExperts 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.

NewsNewly discovered antimicrobial could prevent or treat cholera
Natural antimicrobials called microcins are produced by bacteria in the gut and show promise in fighting infection. A study identifies the first known microcin that targets the strains of bacteria that cause cholera.

NewsClimate anomalies may play a major role in driving cholera pandemics
New research suggests that an El Niño event may have aided the establishment of a novel cholera strain during an early 20th-century pandemic, suggesting climate anomalies could create opportunities for the emergence of new cholera strains.
