[Influence of environmental factors and host on survival of first stage larvae of Muellerius capillaris].
The authors studied the resistance of the first stage larvae of Muellerius capillaris for 75 days period. The survival of larvae was estimated on larvae in faeces and in water. The environmental factor investigated were different temperatures: -18 degrees C, 3 degrees C and 20 degrees C. M.capillaris L1 showed the most tolerance to -18 degrees C. Survival of larvae in water differed from that estimated in faeces. 23,0 -100% larvae in faeces at -18 degrees C have survived 30 days, while about 50% larvae kept in water at 4 degrees C or 20 degrees C survived 28 days. Age of the host was the important factor, which influenced survival of L1 as well. Larvae in faeces from young goats have survived 10 days at -18 degrees C, while larvae in faeces from old goats survived 75 days in the same condition.
