Studies on the possible aetiological role of different Candida species in pathogenesis of dentine caries by monitoring the calcium release from tooth particles.

An in vitro model has been developed for study of cariogenic potential of different Candida species. Slices were prepared from the root of extracted healthy teeth. These disks were covered with inert material, only the central hole, i.

A comparative study on growth in soft-agar, adherence to glass and haemolysis types of coagulase-negative staphylococci.

Growth properties of coagulase-negative staphylococci in the presence and in the absence of human and rabbit serum in soft-agar prepared in modified Staphylococcus 110 broth were studied. The adherent growth was examined in modified Staphylococcus 110 broth and 1% glucose-meat broth. Of 100 strains examined 69% exhibited diffuse, 18% compact, 7% transient and 6% mixed growth.

In-vitro activity of cefetamet (Ro 15-8074) compared with other oral agents.

The bacteriostatic and bactericidal activities of cefetamet (Ro 15-8074) were compared with those of cefadroxil, cefaclor, ampicillin, doxycycline, chloramphenicol and erythromycin against a total of 400 bacterial strains isolated from nosocomial respiratory tract and auditory canal infections. The broth macrodilution method was used to determine antimicrobial susceptibility. None of the compounds was effective against Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus strains.
