title: [Incidence of Parascaris equorum in foals and their mares after strategic use of wide-spectrum anthelmintics for several years].
abstract: In this epidemiological survey 30 foals and their mares from seven breeding farms were investigated. Six farms used wide spectrum anthelmintics strategically at least for three years, on one farm no anthelmintic prophylaxis was practiced. Excretion of P.-equorum-eggs occurred in all breeding farms and in 80% of the foals, but in only one mare. In foals infection with roundworms was detected at the earliest 85 days post partum. Before first shedding of P.-equorum-eggs wide spectrum anthelmintics had been administered to two and to one foal(s) one and two times, respectively, to four animals three times and to one foal each four, five, six and seven times. After metaphylactic use of wide spectrum anthelmintics in the control of an infection with roundworms or other helminths, eggs of P. equorum were found in one foal already 12, 17, 54, 55, 70 and 71 days after treatment with Ivomec-P each and 65 days after use of Panacur in one foal. After application of Banminth roundworm eggs were detected 12, 27, 45, 47, 49 and 62 days in one foal each and 19 and 56 days in two foals each. In eight foals each P.-equorum-eggs were noticed 72 and 196 days after anthelmintic treatment.
