Abstract:
98 staphylococci strains isolated from skin lesions of dogs were tested for their morphological, physiological and biochemical characteristics. These examinations have proved that the majority of the strains was Staphylococcus intermedius (n = 97), and only one was Staphylococcus aureus. The strains were also tested for their sensitivity to bacteriophages. Most of Staphylococcus intermedius strains (n = 75) could be typed with the set of human phages, typing staphylococci isolated from man. Two phages, 676 and Phi 131 have turned out to be highly active towards a large number of the isolates.
Insights
This study identified 98 staphylococci strains from dog skin lesions, finding mostly Staphylococcus intermedius. These canine strains showed sensitivity to human-derived bacteriophages, aiding in their identification and characterization.
Area of Science:
- Veterinary Microbiology
- Bacteriology
- Epidemiology
Background:
- Staphylococci are common bacteria found on skin, causing various infections in animals and humans.
- Accurate identification and characterization of staphylococcal strains are crucial for effective treatment and control of infections.
- Bacteriophage typing is a valuable tool for differentiating staphylococcal strains.
Purpose of the Study:
- To characterize staphylococci strains isolated from canine skin lesions.
- To determine the predominant staphylococcal species in these isolates.
- To assess the susceptibility of these strains to bacteriophages, particularly those used for human staphylococci.
Main Methods:
- Isolation and cultivation of staphylococci from dog skin lesions.
- Morphological, physiological, and biochemical characterization of isolates.
- Bacteriophage susceptibility testing using a panel of human-derived typing phages.
Main Results:
- Out of 98 strains, 97 were identified as Staphylococcus intermedius and one as Staphylococcus aureus.
- A significant number of Staphylococcus intermedius strains (75/97) were successfully typed using human staphylococcal phages.
- Phages 676 and Phi 131 demonstrated high activity against a large proportion of the canine isolates.
Conclusions:
- Staphylococcus intermedius is the predominant staphylococcal species associated with skin lesions in the studied dog population.
- Human bacteriophages can be effective tools for typing staphylococci of canine origin, suggesting potential cross-species applicability.
- Phages 676 and Phi 131 are promising candidates for routine typing of canine Staphylococcus intermedius.
