Adjusting pH of normal saline with dilute hydrochloric acid and dilute NaOH solution to obtain buffer solution with pH of 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and diluting phage with prepared buffer solution to 1 x 1012pfu/mL, the diluted solution was incubated at 37 ℃ for 1 hour in a water bath, diluted 10-fold with physiological saline and then plated on double plates to determine the titer. The statistics of the results after the culture at 37 ℃ for 4-6h in an inverted manner are shown in FIG. 3. As can be seen from FIG. 3, the pH was 6-9After being cultured for 1h at 37 ℃, the titer is only reduced by 1 order of magnitude, and the titer is still maintained at 1011More than pfu/mL, which shows that RDP-SA-18056 has better acid and alkali resistance.
Example 6 genetic test for stability
Continuously passaging RDP-SA-18056 for 30 times, adding the same amount of RDP-SA-18056 and S7 into each generation of culture medium, culturing for 6h for each generation, spreading double plates, and measuring titer; the results are shown in FIG. 4. Continuously transmitting RDP-SA-18056 for 29 generations, measuring its potency, and stabilizing its potency at 1011And pfu/mL or more indicates that the phage has better genetic stability and is suitable for industrial production.
Example 7 determination of phage growth curves
Inoculating salmonella S7 and bacteriophage RDP-SA-18056 to the salmonella suspension in logarithmic growth phase according to the optimal complex number of infection, carrying out water bath for 10min at 37 ℃, then centrifuging for 5min at 12000r/min at normal temperature, discarding the supernatant, removing the free bacteriophage which is not adsorbed on the host, and washing twice with LB broth culture medium. The pellet was resuspended in LB broth at 37 ℃ and quickly placed on a shaker at 37 ℃ and 200r/min for shaking culture and timing. And (3) sampling at regular time to measure the titer, drawing a growth curve by taking time as an abscissa and a bacteriophage titer logarithm value as an ordinate, obtaining the incubation period and the lysis period of the bacteriophage, and calculating the average lysis amount. Mean lysis = end-burst phage titer/initial host bacteria concentration. The results are shown in FIG. 5.
The titer is not obviously changed within 30min after the phage infects host bacteria, which shows that the incubation period is about 30min, the titer of the phage is obviously increased within 40-90min after infection, and then the titer is stable, which shows that the phage lysis period is about 50 min. Through calculation, the phage lysis amount is about 216 PFU/infected cell, and the phage RDP-SA-18056 has the characteristics of short latency, strong lytic capacity and high replication.
Example 8 phage vs host lysis curves
The bacteriophage RDP-SA-18056 is added into the suspension of the host S7, and the bacteriophage lysis curve of the host is obtained because the bacteriophage lysis effect on the host causes the change of the absorbance of OD 600. The host bacterial suspension cultured for 6 hours was inoculated into 100mL of LB medium at a ratio of 1:100, cultured at 37 ℃ for 2 hours with shaking (OD: about 0.15, about 5.0X 108 cfu/mL) at 200rpm, the bacterial suspension was divided into 4 sterilized Erlenmeyer flasks, to 3 of which 0.2mL (about 3.6X 1011pfu/mL, filtered through a 0.22 μm membrane) of phage-proliferated solution was added at the optimum multiplicity of infection, and the average was taken with a control without phage added. The results are shown in FIG. 6.
As can be seen from FIG. 6, the Salmonella phage RDP-SA-18056 is added into the suspension of the host bacteria S7, because the phage has a stronger lysis effect on the host, the OD600 absorbance increases slowly, and the difference between the OD600 increases with the time extension, and the difference between the OD600 and the host tends to be stable when 390-. The experiment further shows that the bacteriophage RDP-SA-18056 has stronger cracking effect, can crack pathogenic bacteria for a long time, effectively controls the production and propagation of host bacteria, and has important application value in animal disease treatment.
Example 8 synergistic Effect of phages and antibiotics
3% of the host S7 was inoculated into LB broth, kanamycin monosulfate and fosfomycin sodium were added to a final concentration of 30ppm, respectively, and 1X 10 was added7The change in OD600 absorbance was measured periodically for pfu/mL of phage RDP-SA-18056. The results are shown in FIGS. 7 and 8.
The OD600 value is gradually increased along with the time, but the combination of the phage and the antibiotic has the absorbance smaller than that of the other two groups, which shows that the antibiotic and the phage can more effectively inhibit the growth of host bacteria, the phage and the antibiotic have synergistic effect, the phage can improve the sensitivity of the antibiotic, and the antibiotic can improve the cracking property of the phage.
Example 9 RTD experiment
Dividing the region on the plate, dropping a drop of host bacteria (about 100 μ L) to the center of the region, air drying, dropping a drop of phage with different dilutions to the spot of host bacteria, air drying, and culturing at 37 deg.C for 16-24 h. According to the growth condition of the host bacteria, the CL concentration is called as the CL concentration (the CL concentration is the concentration of the host bacteria in the environment which can be completely lysed, and can be used for guiding the dilution scheme of the production practice). The result shows that the RDP-SA-18056 still has better lysis effect on the host bacteria after being diluted by 107 times.
EXAMPLE 10 cracking Rate experiments
Under the aseptic condition, 1mL of sample and 1mL of host bacterium liquid (1 × 105 CFU/mL) are respectively taken, incubated for 15 minutes at 37 ℃, uniformly mixed, diluted to 10-1-10-3 gradients by using physiological saline, 100 μ L of each gradient is taken and coated on an LB agar plate, the mixture is placed at 37 ℃, cultured for 24 hours, and each gradient is repeated twice. Simultaneously, 1mL of physiological saline and 1mL of host bacterium liquid (1X 105 CFU/mL) are taken as blank control, and the steps are repeated. Plates with 30-300 colonies were picked for enumeration. The test was repeated 3 times and the average was taken. Phage lysis rate = (1-number of treated group colonies/number of control group colonies) × 100%.
Finally, the experiment proves that the cracking rate of the RDP-SA-18056 reaches 98%, and the RDP-SA-18056 has a good cracking effect on a host and is suitable for being used in the culture process.
Example 11 determination of optimal multiplicity of infection
The phage multiplication solution and the host were added to the LB broth at a ratio of the multiplicity of infection of 100, 10, 1, 0.1, 0.01, and the total volume of the culture system was ensured to be the same. After shaking culture at 37 ℃ and 200rpm for 8h, centrifuging at 12000r/min at normal temperature for 5min, and spreading the supernatant on a double-plate to determine the titer. The results are shown in Table 1.
TABLE 1
Figure 464718DEST_PATH_IMAGE002
As is clear from the data in Table 1, when the multiplicity of infection is 0.1, the growth medium is relatively clear and the titer is the highest after 8 hours of culture, indicating that the optimum multiplicity of infection of RDP-SA-18056 is 0.1.
Example 12 lysis general experiment
30 strains of Salmonella (including 10 strains of Salmonella typhi, 10 strains of Salmonella pullorum, and 10 strains of Salmonella dublin) were screened and subjected to the lysis-stacking experiment. The results show that RDP-SA-18056 can crack 26 strains of Salmonella.
