Framework and antimicrobial sensitivity of bacterial species isolated from complicated forms of contagious ecthyma in sheep and goats

Abstract

The composition of secondary bacterial microflora in complicated clinical forms of contagious ecthyma was investigated in sheep and goats. Nine microbial species were incriminated as potential causative agents of complications. Ps. aeruginosa predominated in complicated stomatitis, related to orf viral infection. This was mostly valid for newborn lambs and goat kids. Frequently, non-sporeforming anaerobes and streptococci were identified. In adult sheep and goats, lesions in the region of the head were most commonly encountered and the major part of complications resulted from secondary infection with S. aureus and Arcanobacterium pyogenes. There were no significant differences in the incidence and the composition of microbial species isolated from sheep and lambs and from goats and kids, respectively. A significant part of Ps. aeruginosa isolates exhibited multiresistance and were sensitive to gentamicin and fluoroquinolones. S. aureus and Arcanobacterium pyogenes isolates were with relatively preserved sensitivity to betalactams and macrolides, but some of the strains were resistant to tetracyclines, enrofloxacin and trimethoprim-potentiated sulfonamides.
