Public Health Alerts provide concise, data-driven information on disease outbreaks and urgent health events. The new series, launched by NEJM Evidence and CIDRAP, offers expert-reviewed reports to support public health evidence-based care.
The winners of the Applied Microbiology International Horizon Awards 2025 have been recognized for their groundbreaking contributions to global challenges through applied microbiology. The awards celebrate excellence across various domains, including drug discovery and sustainable agriculture.
Researchers argue that AI can strengthen pandemic preparedness by detecting emerging diseases earlier. By combining data from humans, animals, and the environment, AI can reveal patterns and provide insights into potential pathogens.
The American College of Chest Physicians (CHEST) has launched a critical care APP education and certification program, covering 11 topic areas including patient-centered care and pharmacology. The CCAPP Certification Exam is now available, with an August 5 deadline to apply for the 2025 exam.
Researchers have synthesized a molecule inspired by Nectandra leucantha and found it to be four times more potent than the prototype, killing Leishmania infantum selectively. The compound's bioavailability was improved, allowing it to circulate in the rat's organism for longer periods.
A University of Toronto study discovered a new communication pathway between the gut and lung, highlighting the role of a little-known protozoan in shaping immune responses. The study found that this microbe can worsen airway inflammation in allergic asthma but provide protection against respiratory infections.
Researchers identified new subtypes of Cryptosporidium parvum in diarrheic calves in Egypt, revealing high prevalence rates and association with lack of hygienic measures. The study's findings underscore the need for further research into the biology of these parasites and their public health implications.
Histomonosis, a deadly parasite that decimates turkey flocks, is being studied for its transmission routes and potential treatments. Researchers aim to understand how the parasite survives and spreads, with a focus on fecal-oral transmission via contaminated feces or cecal droppings.
Researchers have characterized a novel class of proteins in the parasite Leishmania infantum involved in regulating its cell cycle, which could lead to the development of more effective drugs against visceral leishmaniasis. The discovery highlights six F-box proteins essential for L. infantum growth and development, providing potential...
A pilot study found evidence of human co-infections with Bartonella and Babesia odocoilei in six out of seven patients with chronic, non-specific illness. The discovery could lead to better diagnoses and treatments for patients with these infections.
Researchers developed a PCR test that accurately identifies the causative agent of visceral leishmaniasis, a neglected disease affecting Brazil and Latin America. The test can detect co-infection by both Leishmania infantum and Crithidia, with infection by Crithidia more frequent than previously thought.
University of Louisville researchers have received a five-year, $11.7 million National Institutes of Health grant to investigate the connection between microorganisms and disease. The study will focus on various chronic conditions, including Alzheimer's disease, heart disease, diabetes, periodontitis, and colorectal cancer.
A child patient was co-infected with Leishmania infantum and an unnamed Crithidia parasite species, revealing a rare case of non-ulcerated cutaneous leishmaniasis. Genome sequencing confirmed the presence of both parasites, sparking new research questions on disease transmission and host susceptibility.
Researchers at USP in Brazil discovered that Leishmania parasites manipulate the protein gasdermin-D to prevent the immune system from killing them. This allows the parasite to continue replicating and causing disease. The findings offer hope for developing novel treatments for leishmaniasis, a disease affecting 30,000 people annually.
Researchers from Clemson University have discovered a promising therapy for toxoplasmosis, a disease caused by the microscopic protozoa Toxoplasma gondii. The team has enlisted an unlikely ally - the herbicide oxadiazon - in the fight against the single-celled parasite.
A new study led by ISGlobal has identified a gene called PfAP2-HS that allows the malaria parasite to defend itself from febrile temperatures and other adverse conditions within the host. The study found that this gene activates a protective response against high temperatures, helping the parasite survive in the host's environment.
A team of researchers discovered that single-celled organisms like protozoa can protect pathogenic bacteria and prime them for human infection. The bacteria are expelled into the environment after being ingested by protozoa and become more infectious in humans, potentially threatening public health.
An international team of researchers found that improving drinking water quality significantly reduces roundworm infections, with a 22% reduction when combined with sanitation and handwashing. The study suggests that sustainable approaches to disease control could be critical in tackling endemic infections.
Researchers found that compounds from the desert creosote bush exhibit powerful anti-parasitic effects, particularly against Giardia and Naegleria fowleri. The study offers a promising lead for developing new antimicrobial agents to combat deadly parasitic infections.
A new UC Davis analysis reveals that adult sea otters in California are dying at an alarming rate due to diseases and parasites. The study found that nearly two-thirds of the otters died from disease, with parasitic infections being a major cause, including thorny-headed worms and protozoa.
A new fungus has been discovered that is killing frogs and toads worldwide, with 10 species affected in Australia and seven in Panama. The fungus, thought to be suffocating the animals by coating their skin and legs, may be a major factor behind the decline of amphibian populations reported globally.
Scientists found that heart damage in Chagas' disease patients is due to the immune system's reaction to parasitic infections, contrary to previous thought. The study has significant implications for treatment and prevention strategies.
