479. Dachshund neck abscess - microscopic exam

Dachshund Male Neutered 10 years had a large golf-ball swelling on the neck above and between the shoulders. What was it?

SURGICAL DRAINAGE
Blood aspirated and drained (see syringe).
Wound closed and healed in 2 days.
On day 3, a golf-ball swelling appeared.

SURGICAL DRAINAGE
I snipped off the stitches and opened up the wound.
Clear yellow plasma-like fluid flowed out, around 10 ml. What was it?
On day 2, reddish brown fluid seeped out. This continued for next 3 days.
Some yellow pus-like tissues.

MICROBIOLOGICAL EXAM. TISSUE FROM NECK
June 9, 2011, I did a bacterial culture. Results: Moderate growth of coagulase-negative Staphylococcus, sensitive to amoxycillin/clavulan, ceftriaxone, vancomycine, oxacillin.
Resistant to chloramphenicol, erythromycin, penicillin, bactrim, tetracycline and ampicillin.

I gave baytril for 3 days and metonidazole for 6 days. Irrigated the wound with hydrogen peroxide. The 71-year-old mum took back the dog on Day 3. Wound was left open. On Jun 22, 2011, I phoned the owner. All OK.


The owner was in Japan and was most worried. We communicated by phone. As to the cause, it was hard to say. Was it due to the tight bandaging or SC baytril injection? The sibling was given similar drugs SC below the neck and was OK, but he did not have tight bandaging.

Bacterial culture was needed in this case.
