“…1 with S. aureus having the highest prevalence of 53% followed by S. epidermidis with 42% and S. pyogenes accounting for the least occurrence of 5%. This finding is cohesive with the observations from Almeida et al [14], Ekwati et al [15] and Baba et al [5] which confirm the prevalence of the same isolates in wounds of hospitalised patients. Ohabughiro et al [16] also reported the dominance of S. aureus and S. pyogenes in their study on orthopaedic wound infection in medical centres in South East Nigeria.…”

Aim: The prevalence, sensitivity profile and resistance of Gram-positive bacteria in wounds to commercial antibiotics were ascertained in this study. Place and duration of study: University of Medical Sciences Teaching Hospital, Akure, Nigeria, between January and June 2019. Methodology: Wound swabs sample collection, isolation of bacteria, identification of Gram-positive bacteria isolates and antibiotics sensitivity testing of isolated bacteria were determined employing standard protocols. Result: Three Gram-positive bacteria were isolated and presumptively identified to be S. aureus, S. epidermidis and S. pyogenes. S. aureus had the highest prevalence of 53% followed by S. epidermidis with 42% and S. pyogenes accounting for the least occurrence of 5%. Ninety percent (90%) of ten S. aureus strains were resistant to ciprofloxacin while only 10% had intermediate activity. The least resistance of S. aureus strains was against pefloxacin (40%), while to streptomycin, 87.5% of eight S. epidermidis strains were resistant and 12.5% had intermediate sensitivity. Susceptibility was observed in S. epidermidis against pefloxacin (12.5%) while 50% had intermediate sensitivity and 37.5% were resistant. The highest zone of inhibition of S. epidermidis was observed in strain 7 against pefloxacin (16.00±1.00 mm) and in S. aureus by strain 5 against pefloxacin (16.50±2.50 mm). Conclusion: Pefloxacin-sensitive Staphylococcus and Streptococcus species from wound swabs could become resistant overtime and this calls for incessant vigilance on Gram-positive wound bacteria antibiotic-susceptibility appraisal particularly in an antibiotics-abuse setting.

The development of bioactive polymer nanofiber sheets based on eco-friendly components is required to meet the needs of various medical applications as well as to preserve the environment. This study aimed to fabricate biohybrid nanofibers based on water-soluble polymers and aqueous extract of myrrh. The myrrh extract was incorporated into poly(vinyl alcohol)/tragacanth gum nanofiber mats (myrrh@PVA/TG) by the green electrospinning technique. Various characteristics of the prepared fibers such as morphology, fiber diameter distribution, crystallinity, and thermal stability were studied. The results confirmed that the morphology of biohybrid nanofibers was uniform without beads and tragacanth gum plays an important role in controlling the average diameter of fibers and the crystallinity. The antibacterial properties of the developed biohybrid nanofibers were investigated against common pathogens of Gram-positive and Gram-negative bacteria by the standard disc diffusion method. A significant antibacterial activity was observed toward bacterial strains after incorporation of aqueous myrrh extract into nanofibers, which increased on increasing the extract ratio. Due to their eco-friendly components and significant antibacterial activity, the prepared biohybrid nanofibers will open new avenues toward incorporating aqueous herbal extracts into degradable polymer fibers for use in many antibacterial applications.

Developing novel wound dressings containing medicinal plant extracts can have several potential benefits, including improving the therapeutic value of the dressings and reducing the cost of producing wound dressings. In this study, we prepared foam dressing containing Eclipta prostrata leaf extract and gelatin (Eclipta prostrata dressing). Chemical composition was verified using Fourier transform infrared spectroscopy (FTIR), and pore structure was obtained by scanning electron microscopy (SEM). The physical properties, including absorption and dehydration properties, were also evaluated. The chemical properties were measured to determine the pH environment after being submerged with Eclipta prostrata dressings. The results revealed that the Eclipta prostrata dressing had a pore structure with an appropriate pore size (313.25 ± 76.51 µm and 383.26 ± 64.45 µm for the Eclipta prostrata A and Eclipta prostrata B dressings, respectively). The Eclipta prostrata B dressing was more consistent porosity, resulting in a higher absorption capacity and faster dehydration rate. According to physical properties, the Eclipta prostrata B dressing is best used on low-exuding wounds. Furthermore, the Eclipta prostrata A and B dressings make a slightly acidic environment. Therefore, our foam dressing will not interfere wound healing process.
