The present invention provides oligonucleotide probes that are specific for nucleic acid characteristic of a target sequence of 16s ribosomal rna (rrna) in prokaryotes from the genus acinetobacter and pseudomonas. The probes can be employed in a…

Gel toothpaste with tannin extract from cocoa powder is designed to inhibit the growth of major dental plaque bacteria, i.e. S.mutans. This anti bacterial toothpaste can help to prevent the tooth decay cause by the bacteria.
