Article Synopsis
- Dermal contact with certain caterpillar species in Argentina can cause systemic and local poisoning, with several envenomation cases reported, particularly in Misiones province.
- The study compared the protein composition and enzymatic properties of bristle extracts from three caterpillar species known to cause accidents, specifically from the families Megalopygidae and Saturniidae.
- Findings revealed similarities in venom profiles and activities, with specific proteins linked to coagulation disturbances, highlighting important insights into their toxic effects on humans and potential future research avenues.
With the purpose of isolating and characterizing free nitrogen fixing bacteria (FNFB) of the genus Azotobacter, soil samples were collected randomly from different vegetable organic cultures with neutral pH in different zones of Boyacá-Colombia. Isolations were done in selective free nitrogen Ashby-Sucrose agar obtaining a recovery of 40%. Twenty four isolates were evaluated for colony and cellular morphology, pigment production and metabolic activities.
