BACKGROUND Quantitative Microbial Risk Assessment (QMRA), a modelling approach, is used to assess health risks. Inputs into the QMRA process include data that characterise the intensity, frequency and duration of exposure to risk(s). Data gaps for water exposure assessment include the duration and frequency of urban non-potable (non-drinking) water use. The primary objective of this study was t...

BACKGROUND Computer assisted telephone interviewing (CATI) is widely used for health surveys. The advantages of CATI over face-to-face interviewing are timeliness and cost reduction to achieve the same sample size and geographical coverage. Two major CATI sampling procedures are used: sampling directly from the electronic white pages (EWP) telephone directory and list assisted random digit dial...

Experimental inoculations of approximately 100,000 infective Toxocara cati larval eggs were done in twelve pigs. The T. cati eggs used for inoculation were collected from cat's feces. Another group of three pigs served as an uninfected control. Groups of infected pigs were euthanized at seven, 14, 21, and 28 days post-inoculation (dpi). Tissue samples were taken for digestion and histopathology...

Recent studies show that much of Electronic Commerce activities will be conducted via the Internet, such activities encompassing business-business as well as client-business and administration-business relationships. However, the Internet has not been designed to support such activities and it lacks many features, as Quality of Service requirements or Charging and Accounting facilities. At the ...

OBJECTIVE To compare seroprevalences of antibodies against Bartonella henselae and Toxoplasma gondii and fecal shedding of Cryptosporidium spp, Giardia spp, and Toxocara cati in feral and pet domestic cats. DESIGN Prospective cross-sectional serologic and coprologic survey. ANIMALS 100 feral cats and 76 pet domestic cats from Randolph County, NC. PROCEDURE Blood and fecal samples were col...

The Continuous Measurement Survey (CMS) is a proposed monthly survey whose content will be roughly equivalent to the decennial census long form or sample data. During each calendar year it will include sample housing units and special places from all block groups in the nation. Monthly sample size will be 400,000 for the first three years, then decrease to 250,000 in year four. The data collect...

The aim of this study was to investigate the efficacy of two efficient macrocyclic lactone drugs, ivermectin, and moxidectin, on the numbers and distribution of Toxocara cati larvae in experimentally infected mice. Different post-infection periods (48 h and 7 d) and different administration methods (oral and subcutaneous) were compared. Ivermectin and moxidectin were tested (0.2 mg/kg with a si...

OBJECTIVES We aimed to study the prevalence of cardiovascular disease (CVD) risk factors among 11,000 inhabitants in Northern Helsinki, and to identify high-risk individuals in the area and direct them to the local primary-health-care-centred CVD-risk-factor prevention programme. METHOD We conducted a computer-assisted telephone interview (CATI), a descriptive survey and primary care unit sea...

BACKGROUND The stray cats are considered as the sources of emerging humans and domestic livestock pathogens and the zoonoses of public health importance. The present study was aimed to elucidate intestinal helminth infections and infestation with ectoparasites of the stray cats of Ahar City, northwestern Iran. METHODS Totally, 51 stray cats were randomly trapped from different parts of the ci...
