Differences in faecal bacterial communities in coeliac and healthy children as detected by PCR and denaturing gradient gel electrophoresis

Bifidobacterial diversity in human feces detected by genus-specific PCR and denaturing gradient gel electrophoresis.

We describe the development and validation of a method for the qualitative analysis of complex bifidobacterial communities based on PCR and denaturing gradient gel electrophoresis (DGGE). Bifidobacterium genus-specific primers were used to amplify an approximately 520-bp fragment from the 16S ribosomal DNA (rDNA), and the fragments were separated in a sequence-specific manner in DGGE. PCR produ...

Denaturing Gradient Gel Electrophoresis Detected by Genus-Specific PCR and Bifidobacterial Diversity in Human Feces

Study of Bacterial Diversity in Poultry Gut Using Denaturing Gradient Gel Electrophoresis

Bacteria play an important role in the initiation and progression of diseases (not only in disease but affect health status of individual). Populations of digestive microflora in chicken gut change with age and also affected by diet, stressors, and performance enhancers as well as in disease conditions. The aim of the pre-sent study was to know bacterial makeup in chicken gut, using denaturing ...

Denaturing gradient gel electrophoresis profiling of bacterial communities composition in Arabian Sea.

Denaturing gradient gel electrophoresis (DGGE) was used to elucidate spatial and temporal variations in bacterial community composition (BCC) from four locations along the central west coast of India. DNA extracts from 36 water samples collected from surface, mid-depth (-10 m) and dose to bottom (-20 m) during premonsoon, postmonsoon, monsoon were analyzed by PCRfor amplifying variable region o...

Complexity of vaginal microflora as analyzed by PCR denaturing gradient gel electrophoresis in a patient with recurrent bacterial vaginosis.

OBJECTIVE Gardnerella vaginalis has long been the most common pathogen associated with bacterial vaginosis (BV). We aimed to test our hypothesis that symptoms and signs of BV do not necessarily indicate colonization by this organism, and often will not respond to standard metronidazole or clindamycin treatment. METHODS Using a relatively new molecular tool, PCR denaturing gradient gel electro...
