The aim of this study was to compare a recently developed monoclonal antibody (MAb)-based salivary Streptococcus mutans detection method with various selective media using polymerase chain reaction (PCR) as the gold standard. Salivary S. mutans cells were enumerated with a MAb-based method, along with three commonly used selective media, mitis-salivarius-bacitracin agar (MSB), trypticase yeast-...

The genus Campylobacter  is of great importance to public health because it includes several species that may cause diarrhoea. Poultry and poultry products are known as important sources of human campylobacteriosis. In this study, during the autumn months of 2005, a total of 100 samples from poultry carcasses, representing 20 broiler flocks were obtained by rinse test, after the chilling stage ...

Pseudomonas cepacia has recently emerged as an important pathogen affecting cystic fibrosis (CF) patients. We evaluated three selective media to assess their comparative potential for identification of patients colonized with P. cepacia and for efficacy of detection of P. cepacia in environmental fluids. Test organisms included P. cepacia isolates from CF patients (10 each from two CF centers),...

a facile and efficient method for the preparation of 1, 1-diacetates of aldehydes is improved.p2o5/sio2 catalyzed 1, 1-diacetates formation from aldehydes in dry media. advantages of this methodare the use of an inexpensive and selective catalyst with high yields in simple operation and shortreaction time under solvent-free conditions.
