Kacey Diagnostics Quick Reference For Culture & Sensitivity StudyINNOCULATION OF CULTURE BI-PLATE

1) Remove the plate from refrigerator & pre-heat in the incubator @37 degrees for 15-20 minutes prior to inoculating the Kacey MultiChrome bi-plate.

2) Using a sterile inoculating loop ( 20uL) for liquids and a Kacey Sterile Swab for solids ,inoculate the sample onto both sides of the Kacey Multichrome Bi-plate, by utilizing a zigzag streaking motion.

3) Replace clear lid and place Kacey MultiChrome Bi-plate in the incubator upside down (inverted position) and incubate at 37°C +/- 2 degree C for no less then 24 hours . The plate should be examined after 24 hours, but no later than 48 hours after incubation.

INOCULATION OF MULLER HINTON (MH) PLATE

1) Using the Kacey Swab or loop containing the now diluted WST & Turbidity adjusted dilution streak the 1st time the entire periphery of the Mueller Hinton plate making a 360° circle.

2) Streak a 2nd time again the Muller Hinton Plate with a fresh sample of the WST dilution usingbroad strokes starting at theto 3 o’clockposition.

3) Streak a 3rd time again the Muller Hinton plate with a fresh sample of the WST dilution using wide broad strokes starting at the 11 to 5 o’clock position 4) Remove “Sensi-Ring” from the foil pouch with tweezers at the inner tab & place the “Sensi-Ring” facing down onto the MH plate tapping down in non-disk areas, label the specimen to be incubated.5) Place the MH Inoculated plate into an incubator upside down, set timer & incubate for 24 hours. Remove & read inhibition zones with Kacey Clear Acetate Reader.

1 2 3TRANSFER TO MULLER HINTON PLATE USING KACEY “WST” TUBES 1) Taking a Kacey Sterile Swab or Loop carefully dab into the three (3) different places containing the bacteria on the MultiChrome Bi-plate.

2) Immediately place the sterile Kacey Swab or Loop containing the bacteria into the Kacey Working Solution tube (WST which contains 1.0 ml of sterile 0.085%solution). Mix the Kacey Swab or Loop with a gentle twirling motion while in the WST tube for approximately 3-5 seconds.

3) Compare sample to the Kacey Turbidity Standard (white cap) KTS. Sample should match in turbidity, if not add more WST sol (green top) or more sample to match KTS tube. (see enclosed Turbidity Card).

Quick reference only. Refer to detailed instruction manual for additional information.

Treatment.

• Many organisms can be easily identified and treated after the use of the MultiChrome™ system without further testing. However, for organisms that have proven resistant to typical antibiotic regimens it may be necessary to conduct a Sensitivity test.

• Kacey Diagnostics has made “Sensitivity” testing easy, accurate and cost effective as the MultiChrome™ by introducing the Sensi-Ring system in the next section.

Step 1: Obtaining live cultured bacteria from a Kacey MultiChrome™ bi-plate.

• Using the yellow loop, take 3 or 4 passes through the bacterial growth on the MultiChrome™.

For bacterial colonies in both chambers see next slide.

Sensi-Ring™ Supplies For Each Test

For added convenience we also offer a Culture & Sensitivity Starter Kitenough for four complete tests with all the supplies you need. Product #20241

• Kacey Mueller Hinton Plate• Loop• Rayon Swab• Red Top Turbidity Tube• Appropriate Sensi-Ring™• Kacey Micro Incubator

Procedure For MultiChrome bi-plates with bacteria on both the Gram Positive and

Negative side.• In this case, you will prepare two Kacey Maxi Mueller Hinton plates as indicated. One for the (+) and one for the (-).

• To each MH plate you will add the appropriate Sensi-Ring disk Example: place a Gram (+) in the MH plate with Gram (+) and

Gram (-) in the MH plate with Gram (-). Then incubate each.

Mixing with Saline (WST) to dilute

• Insert the yellow loop into the saline and twirl to make a cloudy solution. This is an important step to avoid overgrowth of a bacterial colony.

Comparing Sample to Standard

• Compare your red top tube against the Standard (white top tube) which comes which every kit. They should match closely in turbidity. You can place the barcode card behind them to compare. If sample is too opaque, add more WST solution from dropper enclosed.

Why use Kacey Sensi-Ring™?

In house rapid identification (24 hours) of bacterial antibiotic sensitivity using 8 of the most common veterinary antibiotic choices per ring.

Cost Effective: Less than 1/3 the cost of a commercial laboratory like Antech and Idexx.

Specific Sensi-Ring for both Gram Positive and Gram Negative

System specific Sensi-Ring:- Urinary Tract Infection

- Ear Infection- Skin and Wound Infection

Removing the diluted sample with enclosed Rayon* Swab

• Take a sample using the applicator tip of the swab.

* Do not use cotton swabs even if sterile. Cotton will release a chemical that will alter the results.

Inoculate diluted bacteria onto Kacey Maxi* Mueller Hinton plate

• Using the diluted bacteria solution on the soaked swab, evenly distribute the sample onto a warmed Kacey Maxi Muller Hinton plate (37 degrees 15-20 min).

• Streak the plate as shown below. 11-5, 1-7, 9-3 o’clock

*Kacey Maxi Mueller Hinton plates are “true” 100mm plates. Most commercially sold Muller Hinton plates are 88mm and will not work with this system.

Apply the Sensi-Ring™

• Pick the appropriate Sensi-Ring™ ie. Gram Positive, Gram Negative, UTI or Skin/wound depending on samples origin.

• Grasp the tab on the inside of the ring and lower onto the agar upside down with lettering facing agar, centering the ring with tweezers.

Tamp down Sensi-Ring™

• Make sure that all of the disks touch the agar plate to allow antibiotic diffusion.

Incubate Upside Down

• Place Kacey Maxi Mueller Hinton plate now inoculated upside down to prevent any contamination. • Place into a preheated Kacey incubator at 37 degrees for 24 hours.

24 hours

Remove and read after 24 hours

• Carefully remove plate from incubator keeping it upside down so that Sensi-Ring letters can be seen.

Use the Kacey Zone Reader Card

• Place Kacey Maxi Mueller Hinton Plate upside down with antibiotic letters facing up.• Place Zone Reader over the plate and align the notch of the Reader to the notch of the Sensi-Ring.• Concentric circles should now encircle all of the disks.• Read the Inhibition Zone in mm for each disk.

Notch

Log Test Results

• Using the Patient Lab Report form supplied log inhibition zones for each antibiotic disk.

Treat with appropriate antibiotic

• Based on results, a course of action can now be taken with the most efficacious antibiotic(s).

• The following is a list of commonly found Aerobic Bacteria in small animal practice:

Gram Positive: Staphylococci, Streptococci, Enterococci

Gram Negative: E coli, Proteus, Klebsiella, Pseudomonas

Ear: Staphylococci, Pseudomonas, Proteus, E. coli, Enterococci, Streptococci

UTI: Staphylococci, Proteus, E. coli, Klebsiella, Enterococci, occasionally Pseudomonas

Skin & Wound: Staphylococci, Streptococci, Pseudomonas, Enterococci, Proteus

MRSA & MRSP

Can be detected with Sensi-Ring™ Skin and Wound

Sensi-Rings™ case samples

Case study: 2 year old canine which cultured on the MultiChrome™ both a large colony of Gram Positive Staph in pink and a smaller Strep colony in blue. The colonies when tested for sensitivity using the Sensi-Ring™ indicated sensitivity to a variety of antibiotics not previously used.

Sensi-Rings™ Ability to identify different strains of bacteria.

• Sensi-Rings™ used to identify antibiotic sensitivity on different strains of cultured Staphylococci.

Disposal of plate & clean up

• Once read, plates should be sprayed with a bactericidal agent, covered with its lid taped shut, placed in a plastic bag and disposed of in your bio-hazard bin.

• If you have a Kacey Sanitizer unit (coming soon) follow its instructions. Place lid back on the plate, tape it shut, bag it and dispose of it in your bio-hazard bin.

• Dispose of all used supplies in your bio-hazard bin.

• Spray your counters down and wash your hands in an aseptic manor. Remember, these are live cultures.

• Identify your top performing clinic/hospital for use as reference

• Purchase of one of the following components per month

• Sign official agreement

• Agreement can be cancelled by either party with a 30 day notice in writing of the cancellation
