  The tissue worm Elaphostrongylus cervi is very common in red deer (Cervus elaphus) overall in Europe including Hungary. Its eggs are transported to the lung tissue by the bloodstream, where will be hatched. The first stage larvae are shed likewise the entire lungworm larvae. In the period of 2005-2009 altogether the faeces of 304 farmed and 94 wild living red deer were examined for E. cervi larvae using the Baermann sedimentation method. The larva occurrence data, according to age, sex and the time of sample collection, were analysed by the standard statistical methods used by parasitologists The results are demonstrated in diagrams. E. cervi larvae appeared in the faeces of the calves after six month-of-age (January). In the spring – 10-12 month-of-age – prevalence and intensity values were elevated. In deer over one year-of-age prevalence as high as 50-100% was detected repeatedly with varying intensity in farmed and wild animals equally. The prevalence of larva shedding was fluctuating seasonally in farmed deer, with lower values in early summer. However in calves it was high even in June. In farm stags no larva were detected in June (good body condition) in contrary to the 80% prevalence in November (weak condition after the rutting season).
