Flora and antibiotic susceptibility in 120
ear canals of 60 normal dogs, Onl J Vet Res., 28
(7): 416-422, 2024.
We isolated bacteria
and fungi from 120 ear external canals of 60 dogs as well as antibiotic resistance.
We found 52% ear canals with bacteria and 16% with fungi. These included 33% Staphylococcus
aureus and 26% S. epidermidis 26% from ~58 canals, 7% Bacillus coagulans, ~5% B. lentus 5% B. steato-thermophilus
and 3% Streptococcus agalactiae
from 7 canals. Concerning fungi we found 21% Scopulariopsis spp, 10% Aspergillus,
11% Cladosporium spp, 5% Alternaria spp Penicillium spp and 47% yeasts.
Staphylococci spp. were susceptible
to neomycin (90%),
gentamycin (100%) chloramphenicol (95%), bacillus spp gentamycin (100%), tylosin (90-100% ) and streptococci
spp tetra-oxytetracyclines
(100%) and gentamycin (100%).
