An abscess is any wound which involves the formation of pus. The majority of abscesses in dogs involve primary or secondary bacterial infections, but some abscesses form as a result of necrotic tissue which has formed due to ischaemia - e.g. neoplasia
Commonly involved bacteria include:
- Streptococcus spp
- Escherichia coli
- Bacteroides spp
- Corynebacterium spp
- Porphyromonas spp (dental abscesses)
Treatment of superficial abscesses are relatively straightforward with lancing of fluid-filled swelling, bathing or flushing with antimicrobial solutions such as chlorhexidine.
Abscess involving internal organs can be more problematic, depending on the organ involved.
