Norovirus is the major cause of acute gastroenteritis worldwide. Between November 2012 and June 2013, 1718 stool samples were requested for norovirus antigen testing in the metropolitan areas of South Korea, and 91 samples were genotyped. The norovirus antigen-positive rate peaked at 52.8% in December 2012. [corrected]. A novel norovirus GII.4 variant, GII.4 Sydney 2012, was the most frequently...

Rotavirus infection is the major cause of fatal diarrhea among children younger than five years. We aimed to determine the frequency of rotavirus infection according to age, gender and month of the year. From April 2008 through March 2013, 3,106 fresh stool specimens of children under the age of 16 years were tested for rotavirus antigen, and rotavirus antigen was detected as positive in 422 (1...

Background: Rotavirus infection is one of the most common gastroenteritis in the world, and a million cases are registered to enter hospital every year. Promyelocytic leukemia proteins (PMLs) are IFN-up-regulated proteins, and one of their critical functions is working as antiviral proteins. Recently, promyelocytic leukemia isoform II (PML-II) has been depicted as an isoform responsible for the...

background: helicobacter pylori is the most common cause of chronic infection in the human stomach. the infection has universe prevalence in all age groups. probably, this bacterium is the cause of most common chronic bacterial infection in human beings and infects approximately half of the world population. h. pylori produces urease, an enzyme that degrades the urea in the stomach’s mucous to ...

Several important papers concerning the results of intradermal tests with the peptide antigen of helminths prepared by Yamamura's method which was designed for the extraction of tuberculin active peptide have been published. For examples, Ishii and Morisawa (1961) applied it to paragonimiasis, Yoshimura (1963) to filariasis, and Tada (1966) to gnathostomiasis. Akusawa and Tsuchiya (1965) also d...

Among 345 persons who underwent indirect hemagglutination (IHA) serological assays and assays of specific amebic antigens in their stool samples, 24 of 36 (66.7%) who were seropositive for Entamoeba histolytica had intestinal amebiasis as determined by antigen assays compared with 2 of 309 (0.2%) who were seronegative (odds ratio, 307; 95% confidence interval, 64.9 to 1,451). The estimated cost...
