Species distribution of coagulase-positive staphylococci in animals.
Abstract: A total of 268 isolates of coagulase-positive staphylococci from a variety of animal species, including dogs, horses, cats, monkeys, goats, and cows, were assigned to species on the basis of the API Staph- Ident system (Analytab Products, Inc., Plainview , N.Y.). Of 195 isolates from dogs, 179 (91.8%) were Staphylococcus intermedius, as were 9 of 25 (36%) isolates from horses, 7 of 15 (46.6%) isolates from cats, and 4 of 6 (66.6%) isolates from goats. Only 1 of 10 isolates from monkeys and none of 7 isolates from cows were S. intermedius. Of the remaining 68 cultures, 63 were identified as Staphylococcus aureus and 5 as Staphylococcus hyicus. The latter identifications were rendered doubtful on the basis of conventional tests. Identification appeared to be more certain in the S. aureus sample than in the S. intermedius sample. Distribution of biotypes within the two bacterial species as represented by different API profile numbers and reactivity on test substrates showed no significant variations among the host species, except for the S. aureus biotypes in dogs. Both Staphylococcus species were represented about equally among samples from different tissues and lesions, apart from skin-related infections in dogs, which were associated exclusively with S. intermedius (P less than 0.01). Differences between S. aureus and S. intermedius in antimicrobial susceptibility patterns, prevalence of clumping factor, and occurrence of beta-toxin were found to be not significant.

The research investigated the distribution of coagulase-positive staphylococci, a type of bacteria, in various animal species using the API Staph Ident system. The study revealed Staphylococcus intermedius to be the most prevalent species in most tested animals, except for monkeys and cows, but noted no significant variation in biotypes among the host species.
Research Methodology
- The study collected a total of 268 coagulase-positive staphylococci isolates from different animal species such as dogs, horses, cats, monkeys, goats, and cows.
- Using the API Staph-Ident system, a system designed for definitive identification of staphylococci, all isolates were assigned to their respective species.
Results Obtained
- Out of 195 isolates from dogs, 179 (91.8%) were identified as Staphylococcus intermedius. Similarly, the species accounted for about 36% of isolates from horses, 46.6% from cats, and 66.6% from goats.
- Contrarily, only one isolate from monkeys and none from cows were identified as S. intermedius.
- Among the rest of the 68 cultures, 63 were identified as Staphylococcus aureus and five as Staphylococcus hyicus. However, the identification of S. hyicus was deemed questionable due to the results of conventional tests.
- The researchers observed that bacterial identification was more certain with the S. aureus sample than the S. intermedius sample.
- No significant variation was observed in the distribution of biotypes in the two bacterial species tested among different host animals, except for the S. aureus biotypes in dogs.
- Both Staphylococcus species were represented about equally in samples from different tissues and lesions. However, skin-related infections in dogs were associated only with S. intermedius.
Research Conclusions
- The report concluded that there were no significant differences between S. aureus and S. intermedius in terms of their antimicrobial susceptibility patterns, the prevalence of the clumping factor, and the occurrence of beta-toxin.
- The study provides essential insights into the distribution of coagulase-positive staphylococci in various animals, which can assist in future research and treatment strategies related to these bacterial infections in animals.
