Staphylococcus intermedius is a Gram-positive, catalase positive member of the bacterial genus Staphylococcus consisting of clustered cocci. Strains of this species were originally isolated from the anterior nares of pigeons, dogs, cats, mink, and horses. Many of the isolated strains show coagulase activity. [2]
Non-contagious skin infections can result when normal bacterial or fungal skin flora is allowed to proliferate and cause skin disease. Common examples in dogs include Staphylococcus intermedius pyoderma, and Malassezia dermatitis caused by overgrowth of Malassezia pachydermatis.
Staphylococcus pseudintermedius was first identified as a novel species in 2005 using 16S rRNA gene sequencing of the tRNA intergenic length polymorphisms of the AJ780976 gene loci. [15] [16] [17] Differing strains of S. pseudintermedius, LMG 22219 - LMG 22222, have been identified in various species: cat, horse, dog, and parrot, respectively. [15]
Cefovecin is an antibiotic of the cephalosporin class, licensed for the treatment of skin infections in cats and dogs. It is marketed by Zoetis under the trade name Convenia. It is used to treat skin infections caused by Pasteurella multocida in cats, and Staphylococcus intermedius and Streptococcus canis in dogs. The advantage of using a long ...
Staphylococcus schleiferi along with Staphylococcus aureus and Staphylococcus pseudintermedius are the most common bacteria that cause pyoderma in dogs. [65] Staphylococcus schleiferi is more commonly found in cases of pyoderma with dogs suffering from reoccurring pyoderma who have already undergone antimicrobial treatment.
These examples are not considered infectious diseases because they do not satisfy Koch's postulates – for example Staphylococcus intermedius, a commonly isolated bacteria from skin infections in dogs, would not cause pyoderma when introduced to a healthy dog. In all likelihood that type of bacteria is already present on the skin of a healthy dog.
It is a rare disease in dogs, with cats seven to ten times more likely to be infected. The disease in dogs can affect the lungs and skin, but more commonly the eye and central nervous system. [20] Ringworm is a fungal skin disease that in dogs is caused by Microsporum canis (70%), Microsporum gypseum (20%), and Trichophyton mentagrophytes (10% ...
However, staph infections are still prominent and a cause for concern among healthcare professionals, especially new antibiotic-resistant strains. In the U.S., the incidence of staph infection is around 38.2 to 45.7 per 100,000 person-years, whereas other First World countries have an average incidence rate of 10 to 30 per 100,000 person-years.
