Over 300 pictures are included in VetBact (you can see thumb nail images of most of them by chosing Images on the start page). In connection with the latest course in Bacteriology for veterinary students (sep-oct 2011), several new pictures were added in VetBact, for instance:
- Purple agar plates with maltose for Staphylococcus aureus subsp. aureus, S. hyicus and S. pseudintermedius. The metod is important to differentiate S. aureus subsp. aureus from S. pseudintermedius and S. intermedius. All three species are positive for maltose in tube fermentation, but on agar plates, where the conditions are more aerobic, S. pseudintermedius and S. intermedius are negative (or possibly weakly positive).
Colonies of Klebsiella pneumoniae subsp. pneumoniae cultivated on CLED agar.
- CLED agar plate for Klebsiella pneumoniae subsp. pneumoniae, which may cause urinary tract infections. CLED agar is electrolyte deficient, which prevents swarming of Proteus spp. Lactose fermenters produce yellow colonies on CLED agar, whereas non-lactose fermenters form blue colonies.
- SELMA agar plate for Klebsiella pneumoniae subsp. pneumoniae, which may also cause mastitis. SELMA plates should only be used for milk samples.
- Purple agar with lactose for S. pseudintermedius and Pseudomonas aeruginosa.
