What"s the best way to prevent tuberculosis transmission from wildlife to cattle?
An analysis of relevant published studies indicates that cattle face a hypothetically high risk of getting tuberculosis from wildlife—such as deer, foxes, and wild boar—through indirect interactions, with a much lower risk from direct interaction.....»»
Bee populations at risk of one-two punch from heat waves, pathogen infection
The historically high heat waves that gripped the southwest United States and southern Europe this summer are causing problems for more than just humans. Extreme heat waves affect pollinators and the pathogens that live on them, creating a mutual imb.....»»
How the hospital pathogen Acinetobacter baumannii quickly adapts to new environmental conditions
Each year, over 670,000 people in Europe fall ill because of antibiotic-resistant pathogens, and 33,000 die from the infections. Especially feared are pathogens with resistances against multiple, or even all, known antibiotics. One of these is the ba.....»»
New insights into the evolution of the plague pathogen
The origins of the plague go back to the Neolithic Age, with the oldest findings of the causative pathogen Yersinia pestis coming from human bones around 5,000 years old. In the history of the plague, the late antique Justinianic plague from the sixt.....»»
Researchers discover drug-resistant, often deadly pathogen living in dogs" ears, creating concern it may jump to humans
Scientists at McMaster University and India's University of Delhi have discovered and isolated the first live culture of the drug-resistant pathogen Candida auris from an animal, specifically from the ear canals of stray dogs......»»

Pathogen protein modularity enables elaborate mimicry of host phosphatase
Pathogens have developed an extensive array of proteins during the co-evolutionary arms race with their hosts. This is particularly true for Phytophthora, a genus that causes significant damage to agriculture and forestry. One well-known species, Phy.....»»
Tuberculosis therapy: Smallest particles could deliver drugs to the lungs
Therapy for the dangerous infectious disease of tuberculosis faces the challenge of pathogens frequently being resistant to several common antibiotics. Researchers of Karlsruhe Institute of Technology (KIT) have now developed nanoparticles to deliver.....»»
Cholera bacteria found to form an aggressive biofilm to kill immune cells
Bacteria harness the power of communities. A research group at the University of Basel, Switzerland, has now discovered that the bacterial pathogen that causes cholera forms a novel type of bacterial community on immune cells: an aggressive biofilm t.....»»
Scientists reveal regulation mechanism of soybean cyst nematode responses to chemical signals
Soybean cyst nematode (SCN, Heterodera glycines Ichinohe), is a devastating pathogen in soybean. The infective juveniles of nematodes can use phytochemical signals (semiochemicals) released into the rhizosphere as important cues for host seeking, hos.....»»
