Analysis of Bacteriological Infected Dog and Cat Bite Wounds in Veterinary Medical Staff

Abstract

Bite wounds, human and animal origin, can lead to significant complications if appropriate therapy is not undertaken timeously. The major risk of these aggressions is given by the possibility of systemic propagation of the bacteria involved in the wound and the appearance of complications such as osteomyelitis, septic arthritis, bacterial endocarditis, etc. The identification of pathogenic germs and antibiotic sensitivity test were the key points for a specific therapy that could prevent the spread of infection in the deep tissues. Twenty five biological samples collected from various wounds produced by dogs and cats bites over the veterinary personnel during the medical evaluated. Various aerobic pathogenic and conditional pathogenic bacteria (Staphylococcus aureus, Staphylococcus pseudo intermedius, Staphylococcus intermedius, Staphylococcus epidermidis, Staphylococcus hominis, Staphylococcus xylosus, Staphylococcus warneri, Micrococcus roseus, Streptococcus sp. gr.B, Streptococcus sp. gr.F, Streptococcus sp. gr.G, Enterococcus faecalis, Enterococcus faecium, Trueperella pyogenes, Corynebacterium sp., Bacillus cereus, Pasteurella multocida, Pasteurella canis, Mannheimia haemolitica, Escherichia coli, Pseudomonas aeruginosa, Actinobacillus sp., Neisseria sp) and anaerobic bacteria (Clostridium perfringens, Bacteroides sp.) were isolated. The bacterial drug sensitivity was fluctuating, observing the variations influenced by the natural and acquired resistance of the tested bacterial species. The wounds produced by the bites of dogs and cats have aerobic and anaerobic polymicrobial etiology.
