Establishment of Streptococcus mutans in infants induces decrease in the proportion of salivary α-haemolytic bacteria.

Objective: For paediatric dentists, an indicator to assess caries risk of infants is very important. Conventionally, the number and/or proportions of Streptococcus mutans have been employed as risk indicator; however, because such figures reflect the existing situation, they are not suitable for assessing caries risk of infants that have not yet been infected with S. mutans.

Successful superovulation of cattle by a single administration of FSH in aluminum hydroxide gel.

We investigated whether Al-gel could adsorb and release FSH effectively in vitro and in vivo, and whether a single administration of FSH in Al-gel could successfully induce superovulation (SOV) in cattle. Porcine FSH (pFSH; 30 mg) was mixed with 5 mL of Al-gel; 99.98+/-0.

Responsiveness of rabbits to superovulation treatment by a single injection of follicle-stimulating hormone with aluminum hydroxide gel.

Aluminum hydroxide gel (Al-gel), which is used as an adjuvant, can absorb macromolecules. We investigated the applicability of Al-gel to the sustained release of follicle-stimulating hormone (FSH) as a simplified method of superovulation (SOV) in rabbits. The responsiveness of rabbits to SOV by a single injection of FSH dissolved in Al-gel suspension (3.

PCR detection and identification of oral streptococci in saliva samples using gtf genes.

Oral streptococci are major constituents of dental plaque, and their prevalence is implicated in various pathologies. Therefore, accurate identification of oral streptococci would be valuable for studies of cariogenic plaque and for diagnostic use in infective endocarditis. Many oral streptococci possess glucosyltransferase enzymes that synthesize glucan, which is an obligate component of dental plaque.
