Investigation of bacterial and fungal agents from cutaneous lesions in canine Leishmaniasis

Abstract

The objective of the present study was to determine the bacterial and fungal agents accompanying with cutaneous lesions of dogs suffering from Canine Visceral Leishmaniasis (CVL). Sterile swap samples were taken from cutaneous lesions inspected of ears, dorsal, collar, pectoral, inguinal and interdigital spaces of 20 dogs, in which diagnosis were based on a combination of clinical symptoms, anti-leishmania antibody titers by use of Immunofluorescence antibody test (IFAT) and dogs were further classified according to the Leishvet Guidelines involving serological, hematological, serum biochemical and urinalysis. Swap samples were inoculated to culture media for isolation and identification of bacterial and mycotic agents. 48 Staphylococcus aureus, 4 Bacillus cereus, 8 Staphylococcus epidermidis, 24 Candida albicans, 24 Microsporium canis and 4 Aspergillus niger were isolated and identified in both group of dogs. Regarding antibiotic susceptibility test, the isolates were found 100% susceptible to cefoperazone and amoxicillinclavulanic acid, 53% to danofloxacin, 46% of the isolates were susceptible to enrofloxacin and all of the isolates were resistant (100%) to penicillin G and gentamicin. In conclusion, the antibacterial and antifungal therapy should be provided in accordance with antibiotic susceptibility tests in skin lesions of dogs suffering with CVL.
