Objective: The aim of this study was to evaluate the acidogenicity of dual-species biofilms of bifidobacteria and Streptococcus mutans.

Materials And Methods: The following strains were tested: Bifidobacterium dentium DSM20436, Parascardovia denticolens DSM10105, and Scardovia inopinata DSM10107. Streptococcus mutans UA159 and Lactobacillus acidophilus ATCC4356 were used as control.

Oral microbial colonization in children with sickle cell anaemia under long-term prophylaxis with penicillin.

Background And Objective: Sickle cell anaemia (SCA) is the most frequent haematological hereditary disease.
