II. Susceptibility profiles for specific bacteria or bacterial groups

Bacterial species or genera susceptibility/resistance profiles are displayed in this section. If over ten isolates from individual bacterial species were available, antibiotic activity against the individual bacterial species was examined. In many cases if isolates of one bacterial species were numerous but isolates of related genera were less than ten, the smaller number of isolates from related bacterial species was included in the genera group. Genera that featured less than 10 samples submitted to the LVMDL over the 2004 calendar year were excluded. Some of the isolates were not identified to bacterial species, but instead were categorized as non-fermenters, gram-positive rods, or gram-negative rods. These categories were analyzed in the same manner as the specified genera. There are four sections that comprise the genera profile: A. A graph illustrating the susceptibility/resistance profiles of selected antimicrobial agents

tested on isolates of the organism B. A table showing percent susceptibility for selected antimicrobial agents on isolates of the

organism. Agents effective against 90% or greater of the bacterial samples are illustrated in white boxes; those effective against 80% or greater are illustrated in light grey boxes; and those effective against 70% or greater are illustrated in darker grey boxes. Agents effective against less than 70% of the samples are illustrated in black boxes.

C. The number (n) and percentage of bacterial isolates of the organism from each animal species is shown with a graph illustrating the animal species origin of the samples studied.

D. A graph portraying the anatomical site of sample origin and the animal species of origin. In this graph the following abbreviations or short terms refer to the anatomical sites of origin listed to the right:
