Study illuminates why cowpea mosaic virus is exceptionally effective against cancer

A plant virus that infects legumes, called cowpea mosaic virus, has a special power that you may not have known about: when injected into a tumor, it triggers the immune system to treat the cancer - even metastatic cancer - and prevents it from recurring.

“Keto” molecule could someday become a part of colorectal cancer care and prevention

A molecule produced in the liver in response to low-carb "ketogenic" diets has a powerful effect in suppressing colorectal tumor growth and may be useful as a preventive and treatment of such cancers, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania.

Study estimates the true cost of chickenpox among children in the UK

Chickenpox in childhood results in £24 million in lost income and productivity every year in the UK, although the true cost is likely to be higher, according to new research to be presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Lisbon, Portugal (23-26 April).

Study finds antimicrobial resistance rates to be significantly higher during the pandemic than before

Among those hospitalized during the pandemic, both COVID-19 patients and those tested for SARS-COV-2 but negative, had higher rates of antibiotic-resistant bacterial infections compared to patients hospitalized before the pandemic, according to a study evaluating the pandemic's impact on antimicrobial resistance (AMR) in 271 hospitals across the USA, to be presented at this year's European Congress of Clinical Microbiology & Infectious Diseases in Lisbon, Portugal (23-26 April).

Study highlights a rapidly increasing patient population with long COVID and lack of treatments

A new UK study of more than 2,000 patients after hospitalization with COVID-19 presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2022, Lisbon 23-26), and published in The Lancet Respiratory Medicine shows that, one year after having COVID-19, only around one in four patients feel fully well again.

Heterologous booster dose leads to better SARS-CoV-2 vaccine performance, study shows

A new study on Chile's national COVID-19 vaccination program, to be presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2022, Lisbon 23-26), and published in The Lancet Global Health, shows that giving a different type of vaccine (heterologous) for the third or 'booster' dose than was received for the first two doses, leads to better vaccine performance than using the same (homologous) inactivated SARS-CoV-2 vaccine for all three doses.

Research identifies inadequate PPE management in COVID-19 testing centers as source of major cross-contamination

Lack of glove changes at COVID-19 testing centers in Belgium led to major cross-contamination of samples and a high rate of false positive results, research being presented at this year's European Congress of Clinical Microbiology & Infectious Diseases in Lisbon, Portugal, (23-26 April) has found.

C. difficile study finds the sharing of multiple antibiotic-resistance genes between pigs and humans

A study investigating samples of the superbug Clostridioides difficile across 14 pig farms in Denmark finds the sharing of multiple antibiotic-resistance genes between pigs and human patients, providing evidence that that animal to human (zoonotic) transmission is possible.
