background and objectives: tuberculosis (tb) is the oldest known bacterial disease in humans. due to the rise of morbidity in recent years, early diagnosis of the disease is necessary. materials and methods: in this study we used fluorescent amplification–based specific hybridization (flash) pcr to target is6110 for rapid detection of m. tuberculosis (mtb). to investigate the important factors ...

a multiplex pcr-based assay was developed for detection of salmonella typhi and identification of other salmonella serotypes. three primer-sets were selected from different genomic sequences, malo2-f/malo2-ra primers from invasion gene, parat-s/parat-as as well as tyv-s/tyv-as primers from o-antigen gene cluster of the genus salmonella. this method differentiated salmonella spp., based on size ...

background: neisseria meninigitidis is one of the most frequently encountered microorganisms associated with central nervous system infections. the aim of this study was to evaluate a pcr-based assay for specific and rapid detection of n. meninigitidis in csf specimens.   methods : since april 2002 to july 2006, 130 csf specimens were collected from patients suspected of having bacterial mening...

objectives: salmonella typhimurium is important food-borne pathogen responsible for gastroenteritis. in this work a polymerase chain reaction based enzyme linked immunosorbent assay (pcr-elisa) was developed to identify salmonella typhimurium. materials and methods: the rfb gene which is responsible for biosynthesis of the salmonella o-antigenic lipopolysaccharide was selected as the target s...

Recurrent implantation failure (RIF) has many definitions, but usually authors consider RIF, the failure to achieve a pregnancy fallowing 2-6 IVF cycles in which more than 10 high grade embryos were transferred to the uterus. There are a lot of causes for RIF but two main causes of that are related to embryo and endometrium. Chromosomal abnormalities, zona hardening and problems in culture medi...
