Sterile nutrient agar (NA) plates were exposed to the inner and outer environment of the laboratory for 15 minutes before the commencement of laboratory work in the morning and after closure of activities in the evening after which the plates were incubated at 37oC for 24 hours. Antibiotic susceptibility of the bacterial isolates was done using agar well diffusion technique. The aerial bacterial load outside the laboratory was found to be higher than inside the laboratory. Bacteria isolated include members of the genus Staphylococcus, Bacillus, Lactobacillus, Salmonella, Micrococcus, Streptococcus, Proteus and Escherichia. Bacillus subtilis had the highest frequency of occurrence (31.0%) followed by alpha haemolytic streptococcus (19.0%) while the least frequency of occurrence was shown by Proteus bulgaricus and Proteus species (1.7%). All the bacteria were sensitive to antibiotics tested except Micrococcus luteus. They were equally found to be sensitive to the anti-microbial agent (antiseptic and disinfectant) tested except for the hand sanitizer to which most isolates displayed high resistance. The presence of a wide variety of pathogenic microorganisms in the laboratory shows that the environment requires regular cleaning and disinfection to enhance the safety of staff and students using the laboratory.

Cleaning And Disinfection

Equine dentistry has developed immensely and human dental equipment, such as handpieces, are often used. Measures to avoid the spread of infectious microorganisms are important, but this is challenging since handpieces are difficult to decontaminate. Thus, it is necessary to develop effective IPC measures in equine dentistry. The aim of this study was to contribute to the evidence needed for future evidence-based guidelines on IPC by investigating hygiene in equine dentistry. Used handpieces and dummies (i.e., handpieces not used during dental procedure, reflecting environmental bacterial contamination) and the head support were sampled each day before the first patient, for each patient after treatment, and after decontamination. All equipment was sampled with 3M TM Swab Samplers and the head support additionally sampled with dip slides. After dental procedures, the detected bacterial load was often high on used handpieces, dummies, and the head support. After decontamination, handpieces did not meet the criteria for high-level disinfected equipment. In all but one case decontamination of the head support resulted in a lowered bacterial load. There is a great need for evidence-based guidelines on hygiene in equine dentistry, including IPC measures, to decrease the risk of spreading infectious microorganisms between patients, facilities, and stables.

AbstractBackground:Sink drainage systems are not amenable to standard methods of cleaning and disinfection. Disinfectants applied as a foam might enhance efficacy of drain decontamination due to greater persistence and increased penetration into sites harboring microorganisms.Objective:To examine the efficacy and persistence of foam-based products in reducing sink drain colonization with gram-negative bacilli.Methods:During a 5-month period, different methods for sink drain disinfection in patient rooms were evaluated in a hospital and its affiliated long-term care facility. We compared the efficacy of a single treatment with 4 different foam products in reducing the burden of gram-negative bacilli in the sink drain to a depth of 2.4 cm (1 inch) below the strainer. For the most effective product, the effectiveness of foam versus liquid-pouring applications, and the effectiveness of repeated foam treatments were evaluated.Results:A foam product containing 3.13% hydrogen peroxide and 0.05% peracetic acid was significantly more effective than the other 3 foam products. In comparison to pouring the hydrogen peroxide and peracetic acid disinfectant, the foam application resulted in significantly reduced recovery of gram-negative bacilli on days 1, 2, and 3 after treatment with a return to baseline by day 7. With repeated treatments every 3 days, a progressive decrease in the bacterial load recovered from sink drains was achieved.Conclusions:An easy-to-use foaming application of a hydrogen peroxide- and peracetic acid-based disinfectant suppressed sink-drain colonization for at least 3 days. Intermittent application of the foaming disinfectant could potentially reduce the risk for dissemination of pathogens from sink drains.

Indoor air of a family medical office was analyzed in order to investigate the level of the microbial contamination, because a series of diseases and infections can be transmitted to patients through the air. The determinations were made from October 2018 until May 2019, considering the consulting room, the treatment room, respectively the waiting room. For the enumeration of the total germs number and the streptococcal and fungal populations of the air, the Koch sedimentation technique was used. The microbiological contamination of the air within this study shows the surpassof the suggested standard for the air bacterial load from a medical building. The results highlight a high degree of air pollution in the medical unit, especially in the winter months, when the traffic is more intense and the ventilation is deficient. The aeromicroflora in the treatment room has the highest number of germs, respectively hemolytic streptococci and fungi. The microorganisms isolated in this study from the microscopic examination includes: Penicillium sp., Bacillus sp., Streptococcus sp., Tetrads. Thus, it is necessary to permanently monitor the quality of the air inside the medical office, by applying appropriate cleaning and disinfection methods and by the control of the environmental factors that favor the growth and propagation of microbes.

<div>The failure of frontline antibiotics in the clinic is one of the most serious threats to human health and requires a multitude of novel therapeutics and innovative treatment approaches to curtail the growing crisis. In addition to traditional resistance mechanisms resulting in the lack of efficacy of many antibiotics, most chronic and recurring infections are further made tolerant to antibiotic action by the presence of biofilms. Herein, we report an expanded set of 5-benzylidene-4-oxazolidinones that are able to inhibit the formation of Staphylococcus aureus biofilms, disperse preformed biofilms and in combination with common antibiotics are able to significantly reduce the bacterial load in a robust collagen-matrix model of biofilm infection.</div>
