Introduction:

The synthesis interference of bacterial cell wall is the most common antibiotic mechanism. Cephalosporins have the same mechanism of action as penicillin. However, they have wider antibacterial spectrum, they are more resistant to B-lactamases and better pharmacokinetics properties. Additionally, cephalosporins have higher activity in front of gram-negative bacteria than penicillin.

Objective:

To identify isolated germs in these services and to determine the Staphylococcus aureus resistance to cephalosporins.

Method:

A retrospective, transversal and descriptive study was conducted in Guanabacoa Gynecobstetric hospital from January 2014 to December 2016. selected variables as isolated microorganism, and resistance pattern in front of cephalosporin generations. The isolated germs and the resistance pattern of the germ that prevailed against all generations of cephalosporins were selected as variables. In the Obstetrics Service, the largest number of germs was isolated in the lochia and surgical sites. (69 and 31, respectively).

Results:

In neonatology service, the most frequent isolation occurred in blood culture (35), venous catheter (19) and endotracheal tube (10). In Obstetric service, the most frequent isolation occurred in liquors (69) and the surgical site isolated (31).

Conclusions:

Staphylococcus Aureus was the main microorganism isolated in hospital and its cephalosporin resistance was very high.
