A Longitudinal Study on in Conventionally Reared Commercial Broiler Flocks in the United States: Prevalence and Genetic Diversity.

Poultry meat contaminated with , a major bacterial cause of foodborne gastroenteritis worldwide, is considered the primary source of human campylobacteriosis. Thus, reduction or elimination of in poultry production will have a significant impact on food safety and public health. Despite the significant progress made over the last decades, many puzzles remain about the epidemiology of on poultry farms, hampering the development of an effective control strategy.

Effects of Resolution, Range, and Image Contrast on Target Acquisition Performance.

Objective: We sought to determine the joint influence of resolution, target range, and image contrast on the detection and identification of targets in simulated naturalistic scenes.

Background: Resolution requirements for target acquisition have been developed based on threshold values obtained using imaging systems, when target range was fixed, and image characteristics were determined by the system. Subsequent work has examined the influence of factors like target range and image contrast on target acquisition.

Rising fluoroquinolone resistance in Campylobacter isolated from feedlot cattle in the United States.

Antibiotic resistance, particularly to fluoroquinolones and macrolides, in the major foodborne pathogen Campylobacter is considered a serious threat to public health. Although ruminant animals serve as a significant reservoir for Campylobacter, limited information is available on antibiotic-resistant Campylobacter of bovine origin. Here, we analyzed the antimicrobial susceptibilities of 320 C.

Campylobacter jejuni as a cause of canine abortions in the United States.

Although Campylobacter jejuni is a common cause of ruminant abortion with great economic impact, the organism has rarely been implicated in canine pregnancy loss, with only 2 documented cases to date. In the current report, 2 cases of perinatal death in adult female Bulldogs associated with C. jejuni infection of fetoplacental organs are described.

Epidemiological, clinical and pathological characteristics of colorectal cancer in patients treated at the Clinical Center of Tuzla University.

Aim: To investigate hospital morbidity and incidence of colorectal cancer (CRC) in the Tuzla Canton between 2000 and 2004, as well as mortality incidence and degree of disease progression.

Methods: A total of 383 patients were enrolled in this study, all of them with CRC. Pathohistological analyses were performed in all patients after colonoscopy.

Mortality at the Clinic of Internal Medicine of University Clinical Center in Tuzla during 2008.

Introduction: Accurate information about the cause of death is given by expert teams based on pathological or forensic expertise. Reliable information can be obtained from doctors from clinical-hospital institutions if the deceased person was treated in such an institution and with previously diagnosed disease (hospital mortality). Analysis of hospital mortality provides a lot of data that can be used in planning the hospital beds capacities, the amount of drug procurement, purchasing equipment, organization and creation of highly specialized medical teams (medical team for resuscitation), the number of reanimation techniques, the number of pathologists who are required for autopsy procedures, etc.

Reference frame congruency in search-and-rescue tasks.

Objective: Our aim was to investigate how the congruency between visual displays and auditory cues affects performance on various spatial tasks.

Background: Previous studies have demonstrated that spatial auditory cues, when combined with visual displays, can enhance performance and decrease workload. However, this facilitation was achieved only when auditory cues shared a common reference frame (RF) with the visual display.

Smooth rotation of 2-D and 3-D representations of terrain: an investigation into the utility of visual momentum.

Objective: The potential advantage of visual momentum in the form of smooth rotation between two-dimensional (2-D) and three-dimensional (3-D) displays of geographic terrain was examined.

Background: The relative effectiveness of 2-D and 3-D displays is task dependent, leading to the need for multiple frames of reference as users switch tasks. The use of smooth rotation to provide visual momentum has received little scrutiny in the task-switching context.

Group differences in physician responses to handheld presentation of clinical evidence: a verbal protocol analysis.

Background: To identify individual differences in physicians' needs for the presentation of evidence resources and preferences for mobile devices.

Methods: Within-groups analysis of responses to semi-structured interviews. Interviews consisted of using prototypes in response to task-based scenarios.
