Many articles have summarized the changing epidemiology of Clostridium difficile infections (CDI) in humans, but the emerging presence of C. difficile in foods and animals and possible measures to reduce human exposure to this important pathogen have been infrequently addressed. CDIs have traditionally been assumed to be restricted to health-care settings. However, recent molecular studies indi...

A study has been done to analyse the microbiological quality of salads served along with street foods of Hyderabad. A total of 163 salad samples, 53 of carrot and 110 of onion samples, were collected from four different zones of Hyderabad. About 74% and 56% had Staphylococcus aureus in carrots and onions, respectively. Fifty-eight percent of carrots and forty-five percent of onions samples cont...

Attackers often corrupt data structures to compromise software systems. As a countermeasure, data structure layout randomization has been proposed. Unfortunately, existing techniques require manual designation of randomize-able data structures without guaranteeing the correctness and keep the layout unchanged at runtime. We present a system, called SALADS, that automatically translates a progra...

To the Editor: Stenotrophomonas maltophilia has emerged as an important nosocomial pathogen, especially in debilitated and immunocompro-mised persons (1). However, comparatively little is known of the epidemiology of this bacterium, and sources and routes of transmission of S. mal-tophilia are not well understood. The bacterium is widely distributed in the environment, including in plant rhi-zo...

High prevalence rates of human fascioliasis have been described in several regions of Peru. We surveyed 20 families in an endemic area of Peru in order to determine the proportion of infection with F. hepatica in relatives of diagnosed subjects and in order to identify associated risk factors. The study included feces and blood samples of 93 subjects. Ages ranged from one to 53 (mean = 18.6; SD...
