This study was undertaken in the municipality of Bananal, São Paulo, an endemic area for schistosomiasis with a prevalence under 10% and low parasite load among infected individuals. Our objective was to identify the clinical forms of schistosomiasis among 109 patients in whom the disease had been diagnosed through direct fecal analysis and who had been medicated with oxamniquine at the time of...

In this study, we compared Escherichia coli isolates from chickens with avian cellulitis with those from feces of healthy chickens. Cellulitis-derived strains presented phenotypic and genotypic characteristics of greater virulence than did the fecal isolates. Phylogenetic analysis by repetitive extragenic palindromic-PCR showed that, in agreement with their virulence characteristics, the cellul...

Nonpoint sources of pollution that contribute fecal bacteria to surface waters have proven difficult to identify. Knowledge of pollution sources could aid in restoration of the water quality, reduce the amounts of nutrients leaving watersheds, and reduce the danger of infectious disease resulting from exposure to contaminated waters. Patterns of antibiotic resistance in fecal streptococci were ...

One of the most important routes of transmission for Toxoplasma gondii infection is the ingestion of foods contaminated with cat feces containing sporulated oocysts. The diagnosis of T. gondii infection by fecal microscopy is complicated, as other similar coccidian oocysts are often present in the same fecal specimen. This study aimed to identify T. gondii oocysts in cat feces using a novel PCR...

Bacteroidales species were detected in (tap) water samples from treatment plants with three different PCR assays. 16S rRNA gene sequence analysis indicated that the sequences had an environmental rather than fecal origin. We conclude that assays for Bacteroidales 16S rRNA genes are not specific enough to discern fecal contamination of drinking water in the Netherlands.

Recently, we encountered a female patient who identified the presence of a ghost tablet in her fecal matter. Interestingly, although the patient was prescribed potassium chloride capsules, elemental composition analysis by energy-dispersive X-ray spectroscopy was unable to detect the presence of either potassium or chloride in the fecal tablet remnant.

Risk Factor or Consequence of Poor Outcomes After Rehabilitation? To the Editor: We have read with interest the study written by Harari et al1 regarding the evolution of patients suffering from new-onset fecal incontinence after stroke. These authors observe the long-term fluctuating nature of such condition, the negative impact on mortality and institutionalization, as well as its narrow relat...
