Susceptibility to amoxycillin, cefazolin, imipenem, erythromycin, clindamycin, vancomycin and teicoplanin was also investigated. Of the isolates analysed, 58.8% produced glycocalyx in vitro and 2.5% were penicillin-tolerant. High-level resistance to streptomycin was found in 16.3% of the isolates, but all were sensitive to all other antibiotics tested. We found no significant relationship between glycocalyx production and high-level streptomycin resistance, penicillin tolerance or antibiotic susceptibility, except for a greater susceptibility to clindamycin and vancomycin in isolates that produced glycocalyx. Although our findings reflect the clinically favourable pattern of susceptibility currently found in this species, the appearance in some isolates of resistance, tolerance and glycocalyx production should be investigated because of the risks involved in endocarditis caused by S. mutans.}, organization = {Andalusian Regional Government}, publisher = {Oxford University Press}, title = {In-vitro susceptibility, tolerance and glycocalyx production in Streptococcus mutans}, doi = {10.1093/jac/40.3.359}, author = {De La Higuera, A. and Castillo, A. and Gutiérrez Fernández, José and García-Mendoza, A. and Liébana, J.}, }
