Diagnostic and prognostic indicators, Antibacterial sensitivity pattern and surgical treatment of perireticular abscess in coes and buffaloes

Abstract

Prospective evaluation and long tenn follow up of surgically treated cases of perireticular abscess in 15 buffaloes and 3 cows was done. Majority of the animals (94.4%) were adult and were either recently parturated (7) or pregnant (7). Seventeen C'animals recovered after surgery but 13 survived on long term follow up and 11 becan1e productive members of the herd. The survivability could not be con"elated to the haematological values, age, rUInen motility and duration of illness. Radiography helped in diagnosis of perireticular abscess in 45.490 cases only. Majority of the abscesses were located cranioventrally and were single (of size less than 5 inches) and were associated with potential metallic foreign bodies in the reticulum. In 5 animals, a n1etallic foreign body embedding the abscess was observed. Reticulophrenic adhesions were observed in all the anilnais. Presence of both run1inoperitoneal adhesions and abscess of size more than 5 inches was assessed as poor prognostic indicator. The organisnl isolated from culture of pus samples (10) were Staphylococcus aureus (5), Escherichia coli (2), Corynebacteriullz pyogenes (2), and Streptococcus pyogenes (1). The isolates were highly sensitive to gentamicin, chloramphenicol, streptonlycin, ciprot1oxacin and kanalnycin. A high percentage of resistance was observed for cephalexin, ceftriaxone, cefotaxin1e, penicillin G, cloxacillin and oxytetracycline. Surgical drainage of perireticular abscess into reticular lumen and parenteral medication \vith arnoxicillin, cloxacillin and gentamicin along with supportive n1edication resulted in successful surgical outcome.
