Fecal PCR assay for diagnosis of Helicobacter infection in laboratory rodents.
نویسندگان
چکیده
A fecal PCR assay for detection of Helicobacter infections in laboratory rodents was developed. DNA was isolated from murine fecal pellets, and a region of the 16S rRNA gene conserved among murine Helicobacter species was amplified. The fecal PCR was sensitive and specific. This assay does not require euthanasia of rodents, which is especially important for valuable rodents, such as transgenic mice.

Canine parvovirus type 2 (CPV-2) is one of the most common viruses responsible for acute hemorrhagic enteritis in dogs. A rapid and accurate diagnosis of CPV-2 infection is especially important in kennels in order to isolate infected dogs. The aim of the present study was to compare two laboratory tests i.e., Polymerase Change Reaction (PCR) and Immunochromatography assay (ICA) most commonly us...

Introduction: Helicobacter pylori (H. pylori), is a bacterium responsible for upper gastrointestinal tract diseases. The 16s rRNA is a common H. pylori gene which are usually preferred for diagnosis purpose. The aim of this study was to determine the prevalence and abundance of 16s rRNA in fecal samples and also evaluate correlation between the level of 16s rRNA and activities of the cytokine...

Enteritis due to Campylobacter is the most common cause of acute bacterial diarrhea worldwide. In most cases, infection occurs as a result of consuming contaminated water or food, especially raw meat of fowls. Campylobacters are saccharolytic and fastidious bacteria. These traits limit the number of available biochemical tests by which isolates may be differentiated. These limitations might, in...

ABSTRACT Background and Objectives: Diagnosis of hepatitis E virus (HEV) infection could be missed in some cases if serological tests are used solely. Molecular characterization of HEV is essential for diagnosis of acute and chronic HEV infections, and evaluating the chronic HEV infection status in immunocompromised patients. T...
