Staphylococcus epidermidis

Staphylococcus epidermidis is one of thirty-three known species belonging to the genus Staphylococcus. It is part of our skin flora, and consequently part of human flora. It can also be found in the mucous membranes and in animals. Due to contamination, it is probably the most common species found in laboratory tests.[1]

Ochrobactrum antropi

Ochrobactrum anthropi is a non-fastidious, non-fermenting, Gram-negative cocco-bacillus.It is an emerging nosocomial pathogen, which has been found in environmental and hospital water sources.It has been reported to cause bacteraemias in immunocompromised patients, particularly oncology patients with indwelling catheters.Occasionally, probably because of its ability to survive in water supplies, epidemic outbreaks occur.
Ochrobactrum anthropi is resistant to most cephalosporins and penicillins due, at least in part, to the inducible expression of a single ß-lactamase.
