Sažetak
Lybiostrongylus, blood sucking trichostrongylid nematod, is one of the most important pathogens for ostrich found under the mucosa of the proventriculus. The can cause severe gastritis, anemia, weakness, emaciation and death. Infected birds may also develop secondary impaction of proventriculus and gizzard but also secondary bacterial or mycotic infections of gastrointestinal tract. Three species of lybiostrongylus are described in ostriches: L. dentatus, L. magnus and L. douglassii. In Europe only L. douglassii is found. During the period frome Juny 2002 to Juny 2004, 260 samples of fresh feces were collected frome the 58 farms. Fecal egg count was performed by McMaster method to determine the epg (eggs per gram). The positive farms (when fecal samples contained strongyle eggs) were screened (from each farm 5 fecal samples taken individually was parasitologically examined). For the coproculture identification 10 farms were screened. When possible necropsies of the ostriches from positive farms were also performed. The digestive tract was opened and proventriculus, gizzard as beginning and the end of the large intestine were taken. Necropsies were performed in 60 animals. The prevalence of lybiostronglyles in Croatian farms (31, 6% farms or 60% of tested animals) indicated that high percentage of animals are infected. The reasons of the so high prevalence are still not exactly defined. Most of the affected animals are without any clinical symptoms. Perhaps the most importnat reason is the resistency of accumulated eggs in soil, under optimal climatic conditions for the survival. The impact of L. douglassi on the Croatian ostrich industry remaines undefined.
