Abstract
Aim:
The study was designed to evaluate the common
pathogenic bacteria associated with cutaneous canine
myiasis caused by Cordylobia anthropophaga, and
their prevalence in relation to breed, sex and age
of the infested dogs.
Materials and Methods:
A total of one hundred and thirty three (133)
myiasis wound swabs and Cordylobia anthropophaga
larvae were collected from infested dogs and
analyzed for pathogenic bacteria using microscopic,
cultural and biochemical methods.
Results:
The most commonly encountered bacteria were
Staphylococcus aureus 75 (56.4%), Streptococcus spp.
16 (12%) and Escherichia coli 7 (5.3%). Other
organisms isolated include, Staphylococcus
epidermidis and Corynebacteria species, while mixed
infection of S. aureus and Streptococcus spp were
also observed. The rate of infection was found to be
highest among the age groups 1–20 weeks and least in
the 91 – 100 (week) age groups. The breed of dogs
mostly infected with these bacteria was the local
breed (Mongrel) while the German shepherd /Alsatian
breeds were the least infected and with 58.6% (78)
and 4.5% (6) percentage respectively. Male dogs
showed more propensities to bacterial infection of
all the types isolated and accounted for 60.9% (81)
in contrast to the female dogs with 39.11% (52)
infection rate. Pure bacteria isolates were
frequently encountered 94.7% (126), while mixed
infection accounted for just 5.3% (7).
Conclusion: Our results indicates that several
pathogenic and zoonotic bacteria are associated with
C. antropophaga myiasis in dogs, and should serve as
concern for pet owners and veterinarians.
