Parasit. Hung. 3.159-168.1970 A Recent Case of Human Trichostrongylus Infection in Hungary Dr. Ferenc HOLLÓ — Dr. Judit T. ROVÓ — Dr. Zoltán HÍDVÉGI Helminthological Research Laboratory of the Department of Parasitology, University of Veterinary Science, Budapest — Institute for Public Health and Epidemiology of Comitat Pest, Budapest — Children's Department of the Municipal Hospital, Nagykőrös Human trichostrongylidosis has seldom been encountered in Europe where as it often occurs in the Par and Middle East. Sporadic cases have been reported in the United Kingdom, U.S.A. and Australia. In this country human trichostrorgylosis was first reported in 1937 (VÉGHELYI, MAKARA and PLAMM, 1948), the infection being observed in a child. Further cases have been reported in the last decade:Tricho

strongylus eggs in human faeces were detected in 15 cases in Western Hungary (FRANK and GÉMESI, 1959; HARGITA, 1967), while 10 cases occurred in the Mecsek coal-mining district (MRÁZ et al., 1965), and a single case in Northern Hungary (MIKLER and VILIMSZKY, 1968). Trichostrongylus spp. are nematodes parasitizing principally sheep and cattle, less commonly pigs, rabbits, horses and poultry. In Hungary, as in other countries, they are common parasites of the small intestine of sheep and cattle. The most frequently occurring species is Trichostrongylus colub- riformis (

HF. axel and

. T. vitrinus are found less often)

. This nematode is 4,5-7,5 mm long. A single female may lay 100-200 eggs per day. The eggs are oval and measure 73-94 by 40-50 /•> (average 86 x 43/tc;the eggs of T. axei are about the same size,
