Black rot is caused by the bacteria Xanthomonas campestris pv campestris. This bacteria can infect any plant in the Brassica family but tends to be most damaging in broccoli, cabbage, cauliflower, and kale.
The overuse of antibiotics has led to multiple drug-resistant bacterial strains causing 16 million deaths annually. Bacterial biofilms, constituting 65% of infectious diseases, thrive via quorum sensing (QS). Inhibiting QS offers a promising strategy. Pseudomonas aeruginosa, a major nosocomial pathogen, employs AHLs (3OC12 and C4) for QS signaling, involving receptors QscR, LasR, and RhlR. Natural […]
Lake Erie’s recreational beaches face persistent fecal contamination, impacting water quality and public health. Villa Angela and Headlands beaches in Ohio attract numerous visitors but encounter advisories due to high fecal indicator levels, primarily from gull droppings. Traditional methods assessing gull-related contamination, like gull counts or droppings, prove inadequate due to gulls’ dynamic behavior and […]
Social insects like ants face heightened pathogen exposure due to dense colonies and varied worker roles. We examined immune activity in Myrmica scabrinodis ant workers infected with the non-lethal fungus Rickia wasmannii. Infection by R. wasmannii altered the ant workers’ immune response, notably elevating levels of active phenoloxidase (PO) compared to uninfected counterparts. Interestingly, while […]
