Chlorhexidine is a synthetic antiseptic and disinfectant that has been widely used in the healthcare setting and in everyday household products. In addition to oral rinses and skin preparations, manufacturers have incorporated chlorhexidine coatings into medical devices such as urinary catheters, endotracheal tubes, and central venous catheters in an effort to reduce infection rates. Despite th...

The laboratory diagnosis of tuberculosis usually relies on culture-based isolation of the causative Mycobacterium tuberculosis bacteria. We developed and evaluated the performance of MOD9, a new blood-free derivative of the MOD4 solid medium on which we previously reported for the isolation and culture of mycobacteria. First, inoculation of Lowenstein-Jensen medium with 21 M. tuberculosis isola...

Chlorhexidine gluconate is a bisguanide germicide currently available with 70% isopropanol (Hibistat, Hibitane) or a detergent (Hibiclens, Hibiscrub) for preoperative skin preparation. As these solvents are toxic to the cornea, we investigated the safety and efficacy of aqueous chlorhexidine solutions for ophthalmic use. Chlorhexidine in Tris-glycine buffer was evaluated for retardation of epit...

Background and aims. Streptococcus mutans is the main pathogenic agent involved in dental caries, and may be eliminated using mouthwashes. The objective of this study was to compare the effects of fluoride, chlorhexidine, and fluoride-chlorhexidine mouthwashes on salivary S. mutans count after two weeks of use and determine the prevalence of their side effects on the oral mucosa. Materials and ...

The present investigation was designed to evaluate the effect of the antimicrobial agent chlorhexidine on proteolytic degradation. Chlorhexidine, at a final concentration of 0.01%, significantly (p = 0.05) affected the degradation of the general chromogenic substrate azocoll by both commercial proteases and cell-bound bacterial proteases. Reduction of proteolytic degradation was observed follow...

BACKGROUND Chlorhexidine is a broad-spectrum antimicrobial commonly used to disinfect the skin of patients to reduce the risk of healthcare-associated infections. Because chlorhexidine is not sporicidal, it is not anticipated that it would have an impact on skin contamination with Clostridium difficile, the most important cause of healthcare-associated diarrhea. However, although chlorhexidine ...

Purpose: Benzydamine hydrochloride is a nonsteroidal anti-inflammatory drug that has shown topical anti-inflammatory, analgesic, anesthetic, and antimicrobial activities most often used in radiation induced oral mucositis. The aim of this study was to assess the effectiveness of 0.15% benzydamine hydrochloride as a mouth wash in subjects with severe generalized gingivitis on comparison with 0.2...

Introduction: Due to concerns about histological caries and recurrent caries after the use of sealants, adhesive systems containing fluoride and antibacterial agents have been proposed. The aim of this study was to evaluate the microleakage of sealants after the use of antibacterial chlorhexidine solution on etched enamel with and without the use of fifth- and sixth-generation adhesive systems....

1990s [7–9] . We and other study groups have shown that a significant proportion (5–10%) of IgE-mediated anaphylaxis occurring during general anaesthesia is triggered by chlorhexidine [8, 10, 11] . To put this into perspective, the incidence rate of peri-operative (all causes) anaphylaxis during anaesthesia has been estimated to be 1 in 10,000–20,000 in France and Australia [12, 13] . Hong et a...
