Objective: Study on the viability and nematophagous 
activity of three native isolates of Arthrobotrys (two A. 
oligospora and one A. cladodes var. macroides) after 
passage through sheep’s gastrointestinal tract. 
Design: Field study. 
Animals: Three sheep for each isolate. 
Procedure: Three native isolates of Arthrobotrys (two A. 
oligospora and one A. cladodes var. macroide) isolated 
from soil of different regions of Mazandaran. Each isolate 
was cultured on barley and given in equal amounts to three sheep. Four and five days after administration, the faeces of sheep were recultured for isolation of Arthrobotrys sp. 
and to lest their viability and nematophagous activity using 
faecal culture and dung pat bioassay. 
Statistical analysis: Analysis of variance (ANOVA). 
Results: Conidia of three native isolates of Arthrobotrys 
were reisolated from faeces of infected animals which kept 
their viability and showed 79.75 - 82.26% and 78.79- 
89.27% nematophagous activity in faecal culture and dung 
pat bioassay, respectively. 
Clinical implications: These new isolates are significantly 
able to reduce the number of Haemonchus contortus infective larvae through oral administration and can be 
considered as an alternative for chemotherapy.
