Article Synopsis
- The study focuses on the tick species Amblyomma cajennense sensu stricto, which is common in the Amazon and can transmit Rickettsia amblyommatis.
- Researchers monitored tick populations in a rural area of Maranhão, Brazil, over 24 months, analyzing their activity across distinct dry and rainy seasons.
- Findings indicate a seasonal pattern in the lifecycle of A. cajennense s.s. with larvae thriving in the dry season, nymphs peaking in the transition period, and adults most present during the rainy season, alongside a 7% infection rate with R. amblyommatis.
Gastrointestinal nematodes are a significant concern for animal health and well-being, and anthelmintic treatment is mainly performed through the use of chemical products. However, bioactive compounds produced by plants have shown promise for development as novel anthelmintics. The aim of this study is to assess the anthelmintic activity of protein fractions from Spigelia anthelmia on the gastrointestinal nematode Haemonchus contortus.
