Example two
On the basis of the first embodiment, the present embodiment provides a specific implementation process for facilitating observation of the auxiliary support of the culture dish.
The specific implementation principle flow is as follows:
take a paper diffusion method (K-B method) drug sensitivity test as an example:
and (3) pasting a paper sheet containing a quantitative antibacterial agent on a culture dish inoculated with bacteria to be detected, diffusing the antibacterial agent on the culture dish, culturing for a period of time, observing whether an antibacterial ring appears, and deducing whether the growth of the bacteria is inhibited. The farther the diffusion distance of the drug is, the lower the drug concentration is, the stronger the bacteriostatic ability is, so that the result analysis can be carried out according to the size of the antibacterial ring and the related interpretation standards to judge the inhibition effect of the drug on bacteria, thereby obtaining the conclusion of the drug sensitivity of the tested strain.
The general case is: after incubation for 16 to 18 hours at 35 ℃, the culture dish with the paper sheets attached thereto is placed on a lower light source, the diameter of the bacteriostatic ring (the diameter of the complete inhibition zone) is measured by reflected light from the back of the culture dish by a vernier caliper and visual observation, and the nearest number of millimeters (one integer is read) is read. The area where no visible growth is evident is the edge of the zone. Special cases are as follows: (1) bacteriostatic ring of oxacillin on staphylococcus: fixing a culture dish, facing to a downward light source, observing whether any fine bacterial colony grows in the bacteriostatic ring around the oxacillin paper sheet by utilizing transmitted light, and if any growth which can be distinguished appears, judging the drug resistance of the oxacillin. (2) Bacteriostatic ring of linezolid against staphylococcus: the value of the zone was read with a vernier caliper using transmitted light. (3) The bacteriostatic ring of the compound sulfamethoxazole: the presence of a certain amount of antagonist of folate inhibitors in the culture dish results in slight growth of the test bacteria, so that the slight growth (about 20%) should be ignored when measuring the diameter of the zone of inhibition of the compound sulfamethoxazole, and the place where the growth appears clearly is measured as the boundary of the zone of inhibition.
When the diameter of the bacteriostatic ring needs to be read by reflected light, the culture dish can be placed under the upper light source and then fixed by the culture dish fixing clamp, the upper light source is turned on, the diameter of the bacteriostatic ring is measured by moving the vernier caliper, and the diameter millimeter number is recorded by the reading plate.
When the diameter of the bacteriostatic ring needs to be read by utilizing transmitted light, the culture dish is directly fixed by using the culture dish fixing clamp, the lower light source is opened, the vernier caliper is moved again to measure the diameter of the bacteriostatic ring, and the diameter millimeter number of the reading plate is recorded.
EXAMPLE III
On the basis of the first embodiment, the present embodiment proposes another structure of the culture dish fixing clip. As shown in fig. 3 and 4, the culture dish fixing clamp 2 includes a first arc-shaped clamping piece 201 with a screw 203 and a second arc-shaped clamping piece 202 with a screw hole, the first arc-shaped clamping piece 201 is mounted on the base 1 through the fixing seat 10, and the second arc-shaped clamping piece 202 is in threaded fit connection with the first arc-shaped clamping piece 201 through the nut 11.
