Abstract
The present study entitled “Canine pyoderma: Diagnosis and therapeutic
management” was undertaken w.e.f. 1st August 2018 to 31st May 2019 with the objective
to study the prevalence, identification of causative organism, hemato-biochemical
alteration and to assess therapeutic efficacy in canine pyoderma. The overall prevalence of
pyoderma in dogs was 14.59% with higher occurrence in Labrador breed (40%) with
males (63.75%) being predominantly affected and in age group below 1 year (33.75%).
Clinical signs associated with canine pyoderma were pruritis, pustules, alopecia, papule,
scale and crust, patches, erythema, moth eaten appearance, dry coat, epidermal collaret,
hyperpigmentation, abscess, lichnefication, edema, erosion and fissure. The causative
organisms isolated from canine pyoderma were Staphylococcus species (100%) of which
highest was Staphylococcus intermedius (43.75%) followed by Staphylococcus aureus
(13.75%), coagulase negative Staphylococcus species (12.5%), Staphylococcus
intermedius and Staphylococcus aureus (5%), Staphylococcus intermedius with
Pseudomonas species (6.25%) and Staphylococcus intermedius with Klebsiella species
(11.25%), Staphylococcus aureus with Pseudomonas species (5%) and Coagulase negative
Staphylococcus species and Pseudomonas species (2.5%). The antibiotic sensitivity test
for Staphylococcus intermedius isolates revealed highest sensitivity to linezolid (100%);
Staphylococcus aureus to cephalexin and linezolid (94.73%); Coagulase negative
Staphylococcus species to cephalexin and linezolid (100%); however gram negative
organisms like Pseudomonas species and Klebsiella species revealed highest sensitivity to
enrofloxacin (100%) but complete resistant to cephalexin and linezolid.
Hematobiochemistry revealed anaemia (Low Hb and TEC), leukocytosis, neutrophilia,
reduction in serum albumin, A:G ratio and zinc when compared with apparently healthy
dogs. Dogs treated with cefpodoxime, ceftriaxone and tazobactum and linezolide showed
faster recovery in clinical symptoms weekly than that of cephalexin and enrofloxacin but
complete remission of clinical signs in all the animals was observed only in cephalexin
treated group.
