Biological specimens for community-based surveillance studies: Method of recruitment matters

Survey Research Methods, 2011
Studies requiring the collection of biological specimens are often difficult to perform and costly. We compare face-to-face and telephone interviews to determine which is more effective for return of self-collected rectal swabs from subjects living in ...

Prevalence of diagnostically-discrepant Clostridioides difficile clinical specimens: insights from longitudinal surveillance

Frontiers in Medicine, 2023
BackgroundClostridioides difficile Infection (CDI) is a healthcare-associated diarrheal disease prevalent worldwide. A common diagnostic algorithm relies on a two-step protocol that employs stool enzyme immunoassays (EIAs) to detect the pathogen, and its

Optimum Diagnostic Assay and Clinical Specimen for Routine Rotavirus Surveillance [PDF]

Journal of Clinical Microbiology, 2008
ABSTRACT Rates of detection of rotavirus were compared by diagnostic assay and specimen type. For bulk stools, rates of detection by reverse transcriptase PCR (RT-PCR) and enzyme immunoassay (EIA) were similar, but 18% of healthy controls tested positive by RT-PCR. Testing of bulk stools by EIA appears to be optimum for rotavirus surveillance.

SURVEILLANCE OF APPENDICECTOMY SPECIMEN WITH HISTOMORPHOLOGICAL EVALUATION

Asian Journal of Pharmaceutical and Clinical Research, 2018
Objective: Appendicectomy is the gold standard treatment in acute appendicitis, and in each case, a specimen should be evaluated thoroughly by a histopathologist to confirm the diagnosis and any unknown pathology. The present study aims to find out age and gender prevalence of appendicitis in a tertiary care hospital in Eastern India and various ...

Surveillance on swine farms using antemortem specimens

, 2022
In the recent past, disease control on swine farms was based on vaccination or intentional exposure to pathogens to stimulate immunity and protect against clinical disease. This one-dimensional strategy became increasingly inadequate as farms increased in size and as pathogens resistant to immune control became commonplace, e.g.

Laboratory Operations, Specimen Processing, and Handling for Viral Load Testing and Surveillance [PDF]

The Journal of Infectious Diseases, 2010
RNA remains the most informative and accurate biomarker for human immunodeficiency virus type 1 load diagnostics and for surveillance of drug resistance markers. Viral load testing by nucleic acid amplification currently is a complex and expensive test that is restricted to centralized laboratory testing.
