The study reveals how Wolbachia manipulates the sex lives of its hosts, favoring female offspring to spread the infection. This knowledge could lead to more effective ways to fight human diseases spread by insects like malaria and dengue fever.
Researchers at Uppsala University have identified a new enzyme necessary for DNA synthesis that can also erase DNA from bacterial chromosomes. By studying Salmonella mutants, they found that this enzyme plays a crucial role in spontaneous gene deletions, which can lead to the reduction of DNA content.
Researchers found that bacteria in mosquito's gut inhibit infection with Plasmodium falciparum, the malaria parasite. The study suggests that the microbial flora of mosquitoes stimulates immune activity protecting them from malaria infection.
A study found that disease-causing bacteria exploit the killing machinery of immune cells by increasing the production of an enzyme called arginase. This allows them to survive within macrophages, a type of white blood cell. The researchers observed improved outcomes in mice lacking this enzyme when infected with certain pathogens.
Researchers at Yale University and the University of Chicago showed that mice exposed to common stomach bacteria were protected against Type I diabetes. The findings support the so-called
Researchers compared two microbial killing mechanisms: chemical toxins and viral parasites. Chemical toxins are superior for resident defense against invaders, while viral parasites facilitate faster invasion when carriers are rare.
Researchers found that a bacterial parasite, Pasteuria ramosa, produces intermediate levels of virulence to maximize spore production and host fitness. This tradeoff between host and parasite fitness has important implications for public health strategies to contain emerging parasitic diseases.
A recent study reveals that ants house specific species of bacteria in highly adapted cavities and provide them with nourishment, indicating a long-standing co-evolutionary relationship between the two organisms. This phenomenon has potential implications for addressing antibiotic resistance and may shed light on other natural systems.
Aphids vary in their resistance to wasp parasitism, but new research suggests that the difference lies in the symbiotic bacteria carried inside them. Carrying these bacteria reduces parasitism by up to 40% and demonstrates a heritable form of acquired resistance.
Research reveals how a molecule helps Brucella bacteria evade destruction within macrophages, leading to a deeper understanding of the pathogen. This discovery has significant implications for developing new vaccines and treatments against Brucellosis.
The E. histolytica genome sequence shows a degraded core genome with retained and expanded gene families characteristic of more complex organisms. This study provides insights into the amoeba's unusual shared biology with anaerobic gut bacteria, shedding light on its metabolic processes and potential drug targets.
