background rapid detection of resistant strains of helicobacter pylori in human clinical samples is of major importance in clinical settings. inability of conventional clinical laboratory techniques in detection of these strains usually leads to failure of prescribed therapeutic regimens. objectives the aim of this study was designing a simple and rapid allele-specific pcr (as-pcr)-based method...

the opportunistic pathogen c.albicans is able to cause disseminated infections in immunocompromised patients. microbiological methods for the diagnosis of invasive candidiasis have many problems including low sensitivity, requirement to invasive clinical sampling such as biopsies or multiple blood cultures and need to expertise laboratory stuff. since pcr has proven to be a powerful tool in the...

background pertussis is a respiratory and contagious disease which is mostly caused by bordetella pertussis and b. parapertussis. it usually spreads from person to personduring the incubation or catarrhal phase of the disease. despite of large-scale vaccination, whooping cough is still an endemic disease with several outbreaks. objectives the aim of this study was to determine the prevalence of...

avian influenza (ai) is a viral respiratory disease of domestic and wild birds. in the diagnostic laboratory, it is essential to have methods for rapid detection of avian respiratory viruses. cloacal swabs collected from chickens experimentally infected with h9 subtype ai virus, used in a reverse transcription-polymerase chain reaction (rt-pcr) assay for detection of ai. in infected animals, ai...

aim : we aimed to develop a multiplex pcr assay for specific detection of epec and ehec pathotypes based on specific marker genes. background : about 2.5 million infant’s morbidity in developing countries occurs by e.coli pathotypes because of diarrhea and intestinal diseases. the traditional phenotypic methods are time consuming and sometimes detection and differentiation of the pathotypes are...
