“…Among the potential sources of pathogens that cause HAI, the most common are the patient's microbiota and the hands of healthcare workers [10]. Many studies have shown the role of hands in the transmission of nosocomial infections in Benin [5] [11] [12] [13]. In Togo, many studies have been conducted, but few have been published, hence the lack of available information.…”

Background: Laboratory personnel is at risk of biological contamination leading to laboratory-acquired infections (LAIs). The use of disinfection products is essential in the prevention of these infections. This work aimed to evaluate the effectiveness of antimicrobial agents used in disinfection in bacteriology laboratories in Togo. Methods: This was a cross-sectional study conducted from June to December 2021 in all bacteriology laboratories in Togo. Swabs taken before and after disinfection of surfaces and staff hands were immediately plated on agar media. Counting and identification of isolated colonies were done after 24 hours of incubation. The ANOVA test was used to compare calculated means, prevalence ratio (PR) and 95% confidence intervals (CI) to compare bacterial frequencies. Results: A total of 393 samples were taken, of which 41.2% were from hands. Before disinfection, surfaces were more contaminated than hands with respectively 40.4% and 29.6% (PR = 1.3; CI 95% = [0.9 -1.9]). After surface disinfection with 0.5% of chlorine solution, bacterial elimination was total, but partial on hands washed with soap, with residual contamination of 3.7%. A total of 108 strains were isolated before disinfection of which Klebsiella spp. 38.9% and Staphylococcus spp. 25.0%; after disinfection 4 strains were isolated of which: Staphylococcus spp. 75.0% and Klebsiella spp. 25.0%. Conclusion: Surface disinfection was more effective than hand washing with soap and water. We recom-

“…The development of biocidal formulations, where two or more antimicrobials with different modes of action are mixed, is an interesting approach to potentiate bactericidal efficacy while negating emerging bacterial resistance. Biocidal formulations can also improve antimicrobial efficacy and, therefore, the probability of bacteria to survive disinfection exposure is diminished [40,46,48]. New antimicrobials and formulations must follow critical characteristics such as: (i) to be active at low concentrations; (ii) to have broad-spectrum; (iii) to be low cost; (iv) to have no impact on product usage and organoleptic properties; (v) to be surface compatible; vi) to have low or no toxicity; and vii) to be environmentally friendly [11].…”

Biocide Potentiation Using Cinnamic Phytochemicals and Derivatives

Surface disinfection is of utmost importance in the prevention of bacterial infections. This study aims to assess the ability of ten phytochemicals and related derivatives as potentiators of two commonly used biocides—cetyltrimethylammonium bromide (CTAB) and lactic acid (LA). LA in combination with cinnamic, hydrocinnamic, α-methylcinnamic, and α-fluorocinnamic acids had a factional inhibitory concentration index (FICI) ≤ 1 for Escherichia coli and Staphylococcus aureus. Several phytochemicals/derivatives in combination with biocides improved the biocidal efficacy against early sessile bacteria. The most effective combination was LA with allyl cinnamate (2.98 ± 0.76 log CFU·cm−2 reduction) against E. coli. The combination with CTAB was successful for most phytochemicals/derivatives with a maximum bactericidal efficacy against sessile E. coli when combined with allyl cinnamate (2.20 ± 0.07 log CFU·cm−2 reduction) and for S. aureus when combined with α-methylcinnamic acid (1.68 ± 0.30 log CFU·cm−2 reduction). This study highlights the potential of phytochemicals and their derivatives to be used in biocide formulations.
