Observation of the Antimicrobial Activities of Two Actinomycetes in the Harvester Ant Messor orientalis

open access: yesInsects, 2022
Observations have shown that seeds collected by harvester ants are less likely to mold. Based on evolutionary analysis and other research, it was hypothesized that harvester ants could apply actinomycetes to protect seeds, similar to the protection of ...

Multi‐Targeting Carnosic Acid Kills Drug‐Resistant Helicobacter pylori With Narrow‐Spectrum Activity

open access: yesAdvanced Science, EarlyView.
Carnosic acid selectively eradicates drug‐resistant Helicobacter pylori through a multi‐targeted mechanism involving urease inhibition, membrane disruption, and biofilm eradication. It exhibits no detectable resistance, potent in vivo efficacy, and minimal impact on gut microbiota, positioning it as a promising narrow‐spectrum lead compound against ...

Actinomycetic corneal ulcer [PDF]

open access: yesEye, 1989
A rare case of keratoactinomycosis developing in the absence of any known ocular trauma is described. It showed a dramatic response to penicillin therapy. Steroids should be cautiously used in the presence of active corneal disease. This case highlights the importance of repeated examination of corneal scrapings.
