Parassitosi intestinali umane nel Perugino nel corso del 2005

During 2005 we analyzed stool specimens of 661 subjects, 221 children (1-16 years old) and 440 adults, for O&P (direct and after formalin-etylacetate concentration microscopic observations, Giemsa and modified Ziehl- Neelsen permanent stains when requested). 13.8% of subjects were positive for parasitic infections (13.5% among children and 13.9% among adults). 8.8% of subjects are infected with pathogen parasites (7.2% among children and 9.6% among adults) and 5.0% with not pathogens (6.3% and 4.3% respectively). Among pathogen parasites, in children G. duodenalis was observed in 4.1% of cases,D. fragilis in 0.5%, E. vermicularis in 0.9%, T. trichiura in 1.8%. Among adults, D. fragilis was observed in 5.2% of cases, G. duodenalis in 1.8%, Cryptosporidium spp. in 0.5%, E. vermicularis in 0.5%, T. trichiura in 0.7%, S. stercoralis in 0.7%, H. nana in 0.2%, T. saginata in 0.5%, S. mansoni in 0.5%.Among childrens, 76.7% of pathogen parasites were imported from developing countries, particularly G. duodenalis in adopted ones; instead, among adults, 83.6% of pathogens was observed in home/Italian people, particularly D. fragilis. Cellophane tape test was performed on 40 home children and E. vermicularis prevailed in 22%; modified Baermann method was performed on 42 old subjects and S. stercoralis rabdithoid larvae were observed in 7.1% (but the same ones of O&P).The Authors recommend the O&P in subjects with intestinal aspecific troubles, ipereosinophilia, or other justified situations, emphasizing the importance of a rational, good and responsible O&P and/or other techniques for intestinal parasitosis, because are present, even if not frequent, not only imported, particularly D. fragilis, but also helminths, and not only E. vermicularis.
