“…Various phage sets have been capable of typing 64 to 74 % of canine staphylococcal isolates. Traditional bovine and human phage sets were only capable of typing less than 1 0 % of canine staphylococci (56). A recently described phage set appears to be specific for S. intermedius, but a distinct lytic pattern which might assist in distinguishing pathogenic canine or human isolates from non-pathogenic isolates was not observed (42).…”

Summary It has been 16 years since the identification of S. intermedius as a new species. Numerous investigations using cell wall and DNA analytic methods have now clearly demonstrated significant differences to warrant the creation of this new species. However, studies investigating virulence factors associated with S. intermedius have not uncovered evidence that differentiates virulent from non‐virulent isolates. Therefore, at the present time, it is difficult for veterinary clinicians and microbiologists to determine the clinical significance of many S. intermedius isolates. Host‐bacterial interactions and the hosts' immune status appear to be the factors most crucial in determining the outcome of infections, not the virulence of the organism. Continued research in the virulence factor field will hopefully lead to a better understanding on how we can differentiate virulent from non‐virulent isolates of S. intermedius.

“…Various phage sets are capable of typing 64–74% of canine isolates (Greene and Lammler 1993). The traditional human and bovine phage sets are capable of typing less than 10% of canine staphylococci (Wang 1978). Phage typing has been employed to investigate possible transmission of staphylococci from cats and dogs to human and the results indicated that the dog strains were nontypable with human strain phages but two of the cat strains had similar phage types to some human types (Mann 1959; Mann et al.…”

“…Early phage sets consisted of four to five phages and were capable of typing 67 to 74% of canine isolates (1, 3), whereas traditional bovine and human phage sets were capable of typing less than 10% of canine staphylococci (11). Chinese and Japanese investigators have also described phage sets derived from presumptive S. intermedius isolates (i.e., S. aureus biotypes E and F) utilizing eight to nine phages (6,10,11). Although Shimizu and Kato (6) were able to classify 72.4% of their isolates in 13 lytic patterns, Wang (10, 11) was able to type only 10% of isolates in 12 lytic patterns.…”

Staphylococcus intermedius, a coagulase-positive staphylococcal species, is a common canine pathogen and a rare human wound pathogen. A total of 145 strains of S. intermedius (ATCC 29663, 4 reference strains, 4 human isolates, 44 canine infection isolates, and 92 isolates from canine gingiva) were screened for lysogenic phage by a modified Fisk method. Nineteen phage preparations were prepared for preliminary typing experiments. Lytic activity was observed on 93 of 145 (64.1%) isolates, yielding 44 lytic patterns with individual strains susceptible to one or more phages. Five phages lysed only a single strain, but lytic patterns varied from 1 to 11 lytic phages per isolate. A distinct lytic pattern did not separate canine or human wound isolates from canine gingival isolates. All human wound isolates fell into the two most common canine gingival or wound patterns; the single human nasopharyngeal isolate was not lysed by any phage. Twenty-two of 44 (55%) canine wound isolates and 65 of 92 (71%) gingival isolates yielded lytic patterns. Lysogenic phages are common in S. intermedius. This preliminary study suggests that phage typing may be a useful tool in distinguishing epidemiologically related strains.
