ABSTRACTWe here report on thein vitroactivity of toremifene to inhibit biofilm formation of different fungal and bacterial pathogens, includingCandida albicans,Candida glabrata,Candida dubliniensis,Candida krusei,Pseudomonas aeruginosa,Staphylococcus aureus, andStaphylococcus epidermidis. We validated thein vivoefficacy of orally administered toremifene againstC. albicans and S. aureusbiofilm formation in a rat subcutaneous catheter model. Combined, our results demonstrate the potential of toremifene as a broad-spectrum oral antibiofilm compound.

Introducción: las infecciones por Staphylococcus spp. multirresistentes están asociadas con una mayor morbimortalidad de los pacientes afectados. Objetivo: caracterizar fenotipos de resistencia a meticilina, macrólidos y lincosamidas de 50 aislados de Staphylococcus spp. provenientes de pacientes de un centro hospitalario en la ciudad de Valledupar (Colombia). Materiales y métodos: las pruebas de susceptibilidad a meticilina, eritromicina y clindamicina se realizaron por los métodos de microdilución en caldo y difusión en agar. La resistencia a meticilina se tamizó por la técnica de dilución en agar y la resistencia inducible a clindamicina por la prueba D. Resultados: los aislados de Staphylococcus fueron obtenidos principalmente de heridas (58%) y orinas (12%) y en las áreas de consulta externa (40%), cirugía (24%) y urgencias (10%). Staphylococcus aureus se aisló en un 68%, seguido de Staphylococcus epidermidis (14%), Staphylococcus lugdunensis (8%), Staphylococcus saprophyticus (4%), Staphylococcus haemolyticus (4%) y Staphylococcus hominis (2%). La resistencia a meticilina se encontró en el 36% de los aislados de Staphylococcus aureus y el 8% de los estafilococos coagulasa negativos. Se evidenciaron cinco fenotipos de resistencia; el fenotipo con sensibilidad a eritromicina y clindamicina fue el más frecuente (54%), seguido del de resistencia a ambos antibióticos (14%). La resistencia inducible a clindamicina fue del 12%, encontrándose en el 8% de aislados de Staphylococcus aureus y el 4% de los de Staphylococcus epidermidis. Conclusiones: la prueba D es esencial para detectar el fenotipo de resistencia inducible a clindamicina en aislados de Staphylococcus spp. y evitar su administración frente al inminente fracaso terapéutico.

We examined the in vitro sensitivities of three bacteria: Propionibacterium acnes, and Staphylococcus epidermidis, commonly detected in acne lesions, and Staphylococcus aureus, a common cause of skin infections, to 10 Kampo formulations (Chinese herbal medicines; combinations of powdered extracts of crude drugs). Both Staphylococcus species showed similar sensitivities to all 10 formulations, with minimum inhibitory concentrations (MICs) ranging from 25 to 400 mg/ml. P. acnes, however, was particularly sensitive to one formulation, keigai-rengyo-to (MIC, 0.78 – 25 mg/ml), prompting speculation that it might contain components with strong antibacterial activity to P. acnes. P. acnes showed similar sensitivities to all the other formulations (MIC 6.25 – 200 mg/ml). The ranges of MICs and the MIC50s (concentrations that inhibit 50% of isolates) were very similar to those previously recorded in 1990 for the two Staphylococcus species.

Synthetic antimicrobials have a negative impact on food quality and consumer health, which is why natural antimicrobials are urgently needed. Coagulase-negative staphylococci (CoNS) has gained considerable importance for food poisoning and infection in humans and animals, particularly in biofilms. As a result, this study was conducted to control the CoNS isolated from food samples in Egypt. CoNS isolates were selected on the basis of their antibiotic susceptibility profiles and their biofilm-associated behavior. In this context, a total of 29 different bacteriophages were isolated and, in particular, lytic phages (6 isolates) were selected. The host range and physiological parameters of the lytic phages have been studied. Electron microscopy images showed that lytic phages were members of the families Myoviridae (CoNShP-1, CoNShP-3, and CoNSeP-2 isolates) and Siphoviridae (CoNShP-2, CoNSsP-1, and CoNSeP-1 isolates). CoNShP-1, CoNShP-2, and CoNShP-3 were found to be virulent to Staphylococcus haemolyticus, CoNSsP-1 to Staphylococcus saprophyticus and CoNSeP-1 and CoNSeP-2 to Staphylococcus epidermidis. Interestingly, the CoNShP-3 exhibited a typical polyvalent behavior, where not only lysis CoNS, but also other genera include Staphylococcus aureus, methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Staphylococcus aureus (VRSA), Bacillus cereus and Bacillus subtilis. In addition, CoNShP-3 phage showed high stability at different temperatures and pH levels. Indeed, CoNShP-3 phage showed an antibiofilm effect against Staphylococcus epidermidis CFS79 and Staphylococcus haemolyticus CFS43, respectively, while Staphylococcus saprophyticus CFS28 biofilm was completely removed. Finally, CoNShP-3 phage demonstrated a high preservative efficacy over short and long periods of storage against inoculated CoNS in chicken breast sections. In conclusion, this study highlights the control of CoNS pathogens using a polyvalent lytic phage as a natural antibacterial and antibiofilm agent from a food safety perspective.

AbstractOne of the most challenging complications of total knee arthroplasty (TKA) is periprosthetic joint infection (PJI). There is growing evidence of a good anti-infective effect of intrawound vancomycin powder in total joint arthroplasty. At the same time, various different locally applied substances have become popular in total joint arthroplasty. The objective of this study was therefore to investigate a possible inhibition of the bactericidal effect of vancomycin by tranexamic acid, adrenalin, lidocaine, or dexamethasone. The bactericidal effect of vancomycin was quantified using the established method of the agar diffusion test. The plates were incubated with Staphylococcus aureus or Staphylococcus epidermidis and four wells were stamped out. The wells were filled with vancomycin alone, the tested substance alone or a mixture of the two. The fourth well remained empty as a control. The plates were incubated overnight at 37 °C and the zone of inhibition in each field was measured on the next day. All tests were run three times for each pathogen and mean values and standard deviations of the measurements were calculated. Differences between the substances were tested using the t-test at a level of significance of 0.05. The bacterial growth was homogeneous on all plates. The baseline value for the zone of inhibition of vancomycin was on average 6.2 ± 0.4 mm for Staphylococcus aureus and 12 ± 0.3 mm for Staphylococcus epidermidis. In all other substances, no inhibition was detected around the well. The combination of vancomycin and each other substance did not show any different result compared to vancomycin alone. The bactericidal effect of vancomycin on staphylococci is not altered by tranexamic acid, adrenalin, dexamethasone, or lidocaine in vitro.
