Giardia duodenalis is a well recognised enteropathogen, while Dientamoeba fragilis is rarely detected and consequently it is not recognised as an important human pathogen. In 2002-2003, a survey has been carried out on enteroparasites in faecal samples of outpatients attending a day care centre in the town of Perugia (Central Italy). To improve the(More)
Between 2002 and 2003 the Authors analyzed stool specimens of 1,989 subjects, 966 children (1-14 years old) and 1,023 adults, to investigate for intestinal protozoa too: 380 children and 656 adults with intestinal aspecific troubles, 546 children and 291 adults with acute diarrhoea, 40 children and 76 adults with prolonged diarrhoea. G. duodenalis prevailed(More)
During 2001 we analyzed 1730 pharyngeal swabs for S. pyogenes (SGA): 1142 children (0-10 years old), 132 adolescent subjects (11-17 years old), and 456 adults (18 or more years old). 994 subjects (664 children, 85 adolescent ones, 245 adults) had acute pharyngotonsillitis. In this last group we observed 321 positivities (32.3 %) for SGA: 40.4 % among(More)
During 2001 we analyzed 523 stool specimens (330 children, 193 adults) of patients with recent diarrhoea. We processed all specimens for protozoa, rotavirus, adenovirus, toxin A of C. difficile, and usual enteropathogen bacteria. Salmonella prevailed in 12.8% of cases (16.4% among children, 6.7% among adults), Campylobacter in 9.9% (11.5% and 7.3%), C.(More)
We studied 91 faecal specimens of 38 children and 53 adults in a five-day epidemiological survey between the end of February and the beginning of March, 2006. The subjects were in- or out-patients of Chacas Hospital, Ancash. The O&P were performed with macroscopic evaluation, microscopic (direct and after formalin-ether concentration, FEA) observations and(More)
The Authors report prevalences of intestinal parasitosis among home children and adults during 2002-2004, as in O&P as in acute or prolonged diarrhoea, with particular attention to the role of Dientamoeba fragilis, because often undervalued. Among 3139 subjects, 116 cases of dientamoebiasis (3.7%) and 62 of giardiasis (2.0%) were observed; not typical(More)
We report data concerning our experience during three years (1998-2001) about isolation, identification and susceptibility towards antimicrobial agents of coryneform bacteria in infections of hospitalized/at risk patients. We isolated 54 Corynebacterium spp., with prevalence of C. striatum (8 strains) and C. amycolatum (7 strains), and 1 strain of Oerskovia(More)
The Authors underline the importance to always and correctly investigate also for Campylobacters and related organisms (Clo's) in faeces of humans with enteritis, because prevalent like Salmonella and for surveillance antibiotic resistances; in fact for campylobacteriosis specific therapy is often necessary. Between 2001 and 2005 248 strains of(More)
During 2004, we identified 39 intestinal infections caused by Dientamoeba fragilis and 23 caused by Giardia duodenalis, on 1141 home subjects (3.4% and 2.0% respectively): D. fragilis was observed in 4.5% of O and P (29/644 subjects suffering from aspecific bowel disorders) and in 2.0% of diarrhoeas (10/497); G. duodenalis was observed in 3.1% (20/644) and(More)
