Streptococcus agalactiae transmitted to infants from the vagina during birth is an important cause of invasive neonatal infection. We have done a prospective, randomised, double-blind, placebo-controlled, multi-centre study of chlorhexidine prophylaxis to prevent neonatal disease due to vaginal transmission of S agalactiae. On arrival in the delivery room, swabs were taken for culture from the vaginas of 4483 women who were expecting a full-term single birth. Vaginal flushing was then done with either 60 ml chlorhexidine diacetate (2 g/l) (2238 women) or saline placebo (2245) and this procedure was repeated every 6 h until delivery. The rate of admission of babies to special-care neonatal units within 48 h of delivery was the primary end point. For babies born to placebo-treated women, maternal carriage of S agalactiae was associated with a significant increase in the rate of admission compared with non-colonised mothers (5.4 vs 2.4%; RR 2.31, 95% CI 1.39-3.86; p = 0.002). Chlorhexidine reduced the admission rate for infants born of carrier mothers to 2.8% (RR 1.95, 95% CI 0.94-4.03), and for infants born to all mothers to 2.0% (RR 1.48, 95% CI 1.01-2.16; p = 0.04). Maternal S agalactiae colonisation is associated with excess early neonatal morbidity, apparently related to aspiration of the organism, that can be reduced with chlorhexidine disinfection of the vagina during labour.

Oral candidosis is by far the commonest human fungal infection and manifests in a variety of clinical guises. The main reason for its high incidence appears to be the multiplicity of predisposing factors, which facilitate the conversion of oral commensal Candida to a parasitic existence. Despite the availability of a number of effective antimycotics for the treatment of oral candidoses, failure of therapy is not uncommon owing to the unique environment of the oral cavity where the flushing effect of saliva and the cleansing action of the oral musculature tend to reduce the drug concentration to sub-therapeutic levels. For these and other reasons chlorhexidine is widely prescribed in dentistry both as an antiseptic mouthwash and a denture disinfectant in order to supplement other antifungals. Chlorhexidine has a broad spectrum of antimicrobial activity including Candida albicans and other common non-albicans yeast species. In this review we outline the utility of chlorhexidine as an adjunct to conventional antimycotic therapy in the management of oral Candida infections.

Dental unit water system (DUWS) tubing harbors complex multispecies biofilms that are responsible for high microbial levels at the distal outlet. The aim of this study was to use an established biofilm laboratory model to simulate biofouling of DUWS to evaluate practical, cost-effective, and evidence-based methods of microbial decontamination. Reproducible biofilms were developed in the model over 14 days; decontamination was assessed using total viable counts (TVC) and microscopic-image analysis techniques to view the inner surface of tubing. Flushing did not reduce the biofilm coverage or TVC. Combizyme and ozone did not completely eliminate the viable bacteria (70 and 65% reduction in biofilm TVC, respectively), nor did they remove the biofilm (45 and 57% reduction in biofilm coverage, respectively). Chlorhexidine and Bio2000 (active agent: ethanol and chlorhexidine), Tegodor and Gigasept Rapid (aldehyde based), and Grotanol (hydroxide based) completely eliminated the TVC but did not completely remove biofilm (31, 53 33, 34, and 64.9% reduction of biofilm coverage, respectively). Other products including Grotanol Flussig (phenol based), Betadine (povidone-iodine based), Alpron (chlorite based), and the hydroxide-containing products Sporklenz, Sterilex Ultra, Dialox, Sterilox, Sanosil, Oxigenal, and Grotanat Bohrerbad resulted in a 100% reduction in the biofilm TVC and a >95% reduction in biofilm coverage. The study demonstrated that while many disinfectants achieve a sufficient reduction in TVC they may not necessarily remove unwanted biofilm from the tubing surfaces as tested in this laboratory-controlled biofilm model.

Antiseptic flushing of the canine prepuce and its exclusion from the surgical field are recommended before abdominal surgery to reduce the risk of bacterial contamination. The authors cultured the preputial cavity of 60 dogs prior to and following flushing with 0.05% chlorhexidine diacetate, 1% povidone-iodine, or 0.9% saline control. Bacterial growth was evaluated using a semiquantitative method, and bacterial organisms were subsequently identified. There were no significant differences between povidone-iodine and the saline control in any of the variables assessed. Chlorhexidine resulted in a significant decrease in the proportion of positive postflush cultures compared with povidone-iodine. Although not significant, the difference in adverse reactions between povidone-iodine (25%) and chlorhexidine diacetate (5%) suggests clinical relevance. Based on the results of this study, a 2 min flush with 0.05% chlorhexidine diacetate is recommended for presurgical preparation of the preputial cavity.
