Both have everything but the incubator and the appropriate antibiotic sensitivity disks. Troy Biologicals doesn't sell direct to individuals, you must use a distributor. Both kits have quad plates , but the sensitivity plate in the Birdseye Kit is a separate plate, while the Bactistar sensitivity plate is attached to the quad plate. The advantage to having two separate plates is that if the bird only cultures nonpathogenic flora, you don't need to use a sensitivity plate which saves you money and equipment. The Birdseye Kit also gives you an extra culture medium, Biggy Agar in a separate tube.
Biggy agar is used to test for candida.
A gram scale is necessary to weigh your bird so that accurate medication dosages can be calculated. Both Microbio and Physicians Laboratory Supply Co. sell plates and other culture equipment. Plates can be purchased in groups of ten. Troy Biologicals sells a color chart for reading cultures. All rights reserved.
