To evaluate the effectiveness of an intensive hand hygiene campaign on reducing absenteeism caused by influenza-like illness (ILI), diarrhea, conjunctivitis, and laboratory-confirmed influenza, we conducted a randomized control trial in 60 elementary schools in Cairo, Egypt. Children in the intervention schools were required to wash hands twice each day,(More)
BACKGROUND The global burden of disease attributable to seasonal influenza virus in children is unknown. We aimed to estimate the global incidence of and mortality from lower respiratory infections associated with influenza in children younger than 5 years. METHODS We estimated the incidence of influenza episodes, influenza-associated acute lower(More)
An abattoir survey of 212 sheep of different ages was undertaken to determine the local epidemiological transmission patterns of Echinococcus granulosus in the central Peruvian Andes. Overall prevalence of the disease in sheep in this survey (which ended in July 1996) was 77.4%, with 96% of sheep aged > or = 6 years being infected. Of 1165 cysts examined,(More)
INTRODUCTION Zoonotic diseases are an important cause of human morbidity and mortality. Animal populations at locations with high risk of transmission of zoonotic pathogens offer an opportunity to study viral and bacterial pathogens of veterinary and public health concern. METHODS Blood samples were collected from domestic and imported livestock(More)
BACKGROUND In response to the potential threat of an influenza pandemic, several international institutions and governments, in partnership with African countries, invested in the development of epidemiologic and laboratory influenza surveillance capacity in Africa and the African Network of Influenza Surveillance and Epidemiology (ANISE) was formed.

A blinded, randomized placebo-controlled trial assessed the efficacy and safety of oxfendazole for the treatment of ovine hydatid disease. Cyst fertility and parasite viability were measured following daily, weekly, and monthly treatment schedules with 30 mg of oxfendazole per kg of body weight. The 12-week trial was conducted in 215 adult sheep in the(More)
Brucellosis poses a significant public health problem in Mediterranean countries, including Egypt. Treatment of this disease is often empirical due to limited information on the antibiotic susceptibility profiles of Brucella spp. in this region of the world. The aim of this study was to determine the antibiotic susceptibility profiles of Brucella blood(More)
Salmonella DNA adenine methylase (Dam) mutants that lack or overproduce Dam are highly attenuated for virulence in mice and confer protection against murine typhoid fever. To determine whether vaccines based on Dam are efficacious in poultry, a Salmonella Dam(-) vaccine was evaluated in the protection of chicken broilers against oral challenge with(More)
Salmonella mutants lacking DNA adenine methylase (Dam) are highly attenuated for virulence and confer protection against oral challenge with homologous and heterologous Salmonella serovars in mice and chicken broilers. To determine whether vaccines based on Dam are efficacious in preventing early colonization of newly hatched chickens, a Salmonella(More)
AIM To determine Salmonella enterica serovars and antibiotic resistance (ABR) in the human waste stream. METHODS AND RESULTS Sampling of influent wastewater at municipal treatment plants in two California cities was performed by collecting composite samples, over a 24-h period, from the treatment plants on five to six occasions. Serial water quantities(More)
