Résumé:
The first chapter aimed to identify, document and analyze phytotherapeutic
knowledge in the treatment of animal diseases, as well as the use of medicinal plant
species in the rural community of Pólo Hélio Pimenta, km 19 of the city of Porto Acre -
Acre / AC, Brazil. Sixty families from the community were interviewed and a structured
questionnaire was used for the study. The results obtained in this study indicated 43
species of medicinal plants. The consensus informant factor (IFC) showed that the
digestive category presented the highest values, and that the problems with
endoparasites (anthelmintic) stood out with the highest number of indications. The
value of one species per informant (UV) shows a direct correlation with the IFC where
the plant species most cited by the informant are grouped in the highest indication
categories. Regarding the animal species, dogs and cats were the most reported. The
second and third chapter had as proposal to evaluate the anthelmintic effect of ethanolic
extracts of C. guianensis and U. guianensis on gastrointestinal nematodes of naturally
infected sheep. Crossbred sheep were administered orally 10 mL of root extract (1.06
mg / mL) and C. guianensis stem (0.34 mg / mL) on days of treatment (0,1,2,3,15 ,
16,17,18) and root (0.57mg / mL and 1.14mg / mL) and stem (1.25mg / mL and 2.5mg /
mL) of U. guianensis on days of treatment (0,7,14 , 21.28). For each treatment group,
nine animals were used for C. guianensis, five animals for U. guianensis and five
animals for the control group. The results show that there was a reduction in the
numbers of eggs per gram of faeces (OPG) in the groups treated with C. guianensis and
in the U. guianensis root at the concentration of 1.14mg / mL. Regarding the number of
third instar larvae (L3) of gastrointestinal nematodes recovered from sheep after
treatment observed that the animals treated with C. guianensis presented a reduction in
the percentage of larvae of 70 and 55% for root and stem. With respect to the group of
U. guianensis, the animals treated with closantel, root (1.14mg / mL) and stem (1.25mg
/ mL) were statistically different (p0,05%) from the other treatments presenting 68% ,
68% and 86% respectively of reduction in the number of larvae. Thus, we conclude that
C. guianeneis and U. guianensis have antihelmintic activity on gastrointestinal
nematodes of sheep, thus being a good alternative in the control of endoparasites in the
Western Amazon.
