Aerobic and microaerophilic bacteria isolated from Psoroptes cuniculi.
The bacterial flora of Psoroptes cuniculi removed from nine naturally infested rabbits was investigated. Mites were collected in sterile glass tubes; half of the mites were surface sterilised, the others were not. All mites were crushed using sterile glass pestles, placed in Buffered Peptone Broth, smeared on to several culture media, by glass rods, and incubated at 37 degrees C for 48 hours, aerobically and/or in 5% CO2. Representative colonies were removed and streaked on to several selective media. Different colour changes of the selective media used, macro and microscopic morphology, ability to grow aerobically, Gram staining, and several biochemical tests evaluated with API test strips, were used for bacterial identification. Staphylococcus aureus, Serratia marcescens and S. odorifera were the bacteria isolated from surface sterilised mites.
