Molecular characterization [Pcr-Based Methods] of Staphylococcus aureus isolated on dogs and cats

A total of 36 isolates of Staphylococcus aureus from hospitalised and out patient dogs and cats were typed by RAPD-PCR, and 36 isolates were selected for further typing by ERIC-PCR and Coagulase gene-PCR and Coagulase gene RFLP, indicating a low degree of polymorphism in the coagulase genes. In this study, it is noticeable that RAPD-PCR displayed desirable typing quality by its ability to group the apparently related isolates from outpatient and hospitalised cats and dogs, whereas ERIC-PCR has the tendency to group the isolates into a single major cluster

SDS page of whole cell protein, immunoblotting and protein A assay for typing of staphylococcus aureus isolated on dogs and cats

A total of 36 isolates of Staphylococcus aureus from hospitalised and out patient dogs and cats were typed using SDS PAGE of whole cell protein, immunoblotting and protein A assayment by ELISA test. 15/24 and 14/24 profiles were recognised using SDS PAGE and immunoblotting respectively. It is concluded that SDS PAGE of whole cell protein and immunoblotting could be used as a typing methods for the characterisation of S. aureus strains. Protein A assayment could be used for the detection of S. aureus strains in samples but could not be used to differentiate between different strains
