Example Five: Examining Antibacterial Properties of Placental Tissue Components
[0069] As the use of antibiotics has increased across the globe, the rate of antibiotic resistance has grown leading to a pressure to develop new antibiotics. Placental tissue is known to exhibit antimicrobial activity against bacteria common to public areas and medical facilities, making it a viable candidate for antibiotic use. Further, antimicrobial peptides have been reported to be released within placental tissue layers, for example human beta-defensin (41). However, there are no antibacterial products currently on the market that take advantage of these properties of placental tissue. With this knowledge in hand, various components of placental tissue were tested to determine the portions that exhibited antibacterial activity. Dried placental tissue samples were micronized and rehydrated. The goal of this experimental study was to take the described products and test them on multiple bacterial species, some common to human skin, found in hospital/surgical environments. The described products (creams) are contemplated for use during surgical procedures to limit chances of bacterial infection. The bacterial species tested were Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Mycobacterium smegmatis, and Methicillin-Resistant Staphylococcus aureus (MRSA). A disk diffusion method was used. Bacteria were inoculated into nutrient broth, incubated overnight at 37° C., and then diluted in water to match the turbidity of a McFarland Standard. The bacteria were spread on Mueller-Hinton Agar plates. Disks with 20 uL of the hydrated tissue were placed on the inoculated plates and incubated at 37° C. overnight. Analysis of the plates showed that many of the placental tissues had a zone of inhibition around the disks, which indicated antibacterial activity (
Cream Formulations
[0070] Creams were formulated as described above through processes of micronization and rehydration. Eight samples (Table 3) were formulated having different ratios of amnion/chorion membrane (AC Placental) and umbilical cord/amnion tissue (UC:A).
TABLE-US-00003 TABLE 3 50:50 AC Placental UC:A Cream Sample (%) (%) 1 100 0 2 0 100 3 40 60 4 20 80 5 10 90 6 5 95 7 3 97 8 1 99
Disk Diffusion Assay
[0071] A disk diffusion assay was performed to see how the different components of the placental tissue might lead to differences in antimicrobial activity against the bacteria through analysis of the zone of inhibitions produced after the assay. Overnight cultures were made for each bacterial species and were incubated at 37° C. in a shaking incubator. The bacteria were then diluted in sterile water to match a McFarland standard and spread on MHA plates. 20 μl of each cream sample was applied on 6 mm diameter disks and aseptically placed onto the swabbed plates. A Tetracycline BBL™ Sensi-Disc™ Antimicrobial Susceptibility Test Disk was used as a positive control and distilled water was used as a negative control. 0% AC cream contained Warren Laboratories Georges Aloe Vera. The plates were incubated at 37° C. Diameters were measured after incubation.
Results of Disk Diffusion Assay
[0072] Escherichia coli(
[0073] Creams composed of more AC placental powder exhibited greater antibacterial activity (large disk diameter) and creams composed of 20% and 10% AC placental powder showed similar activity (similar disk diameters).
Staphylococcus aureus (
[0074] Creams composed of more AC placental powder exhibited greater antibacterial activity (large disk diameter). All creams exhibited antibacterial activity, even at the lowest concentration of 1% (Sample 8).
Pseudomonas aeruginosa (Micrococcus pyocyaneus) (
[0075] Creams composed of more AC placental powder exhibited greater antibacterial activity (large disk diameter). A significant drop in the zones of inhibition was observed between creams composed of 40% (Sample 3) AC placental powder and 10% (Sample 4) AC placental powder. There was no significant difference in the zones of inhibition between creams composed of 100% AC placental powder and positive control.
Mycobacterium smegmatis (
[0076] Creams composed of more AC placental powder exhibited greater antibacterial activity (large disk diameter). There was no significant difference in the zones of inhibition between creams composed of 100% or 40% AC placental powder and positive control. Creams composed of 1% (Sample 8) AC placental powder showed no antibacterial activity.
Methicillin-Resistant Staphylococcus aureus (MRSA) (
[0077] Creams composed of more AC placental powder exhibited greater antibacterial activity (large disk diameter). Creams composed of 100% (Sample 1), 40% (Sample 3), 20% (Sample 4), and 10% (Sample 5) AC placental powder had a larger zone of inhibition than the positive control with 100% (Sample 1) and 40% (Sample 3) being significantly higher. Creams composed of 1% (Sample 8) AC placental powder showed no antibacterial activity.
Test for Bactericidal and Bacteriostatic Activity
[0078] The bactericidal and bacteriostatic activity was measured by swabbing the zone of inhibition on the plates followed by swabbing on fresh nutrient agar plates and incubating the newly swabbed plates overnight at 37° C. (
[0079] The results showed variation in the modes of inhibition of the creams. All creams exhibited bactericidal activity at 100% and 40% concentrations.
[0080] MRSA exhibited bactericidal activity at concentrations of 100%, 40%, 20%, and 10% of AC placental powder and bacteriostatic activity at concentrations of 5% and 3% AC placental powder (
[0081] Mycobacterium smegmatis showed results similar to that of MRSA by exhibiting bactericidal activity at concentrations of 100%, 40%, 20%, and 10% of AC placental powder and bacteriostatic activity at concentrations of 5% and 3% AC placental powder (
[0082] Pseudomonas aeruginosa (Micrococcus pyocyaneus) exhibited bactericidal activity at a concentration of 40% AC placental powder and bacteriostatic activity at concentrations of 100% and 20% AC placental powder (
