Z A . 2000. Samples were obtained from 65 unmedicated adult dogs, processed for isolation of Staphylococcus species and tested for susceptibility to penicillin G, gentamicin, oxacillin, tetracycline, trimethoprimsulphamethoxazole, streptomycin, ampicillin and rifampin. Forty-four isolates were obtained, which represents 67Á7% of samples. Coagulase-negative species were most commonly found, and the most frequently isolated staphylococcus species were Staph. epidermidis and Staph. aureus. Other species, such as Staph. simulans, Staph. haemolyticus, Staph. saprophyticus and Staph. intermedius were also isolated. Resistance to antibiotics was frequently observed, with 90Á9% of the isolates showing resistance to at least one drug. The most active antimicrobial agents against staphylococci isolated from otitis externa of dogs were rifampin and oxacillin. Multidrug resistance was a common ®nding, and one strain of Staph. haemolyticus species, was resistant to all tested antimicrobial agents. Resistance to three or more different drugs was a common ®nding, observed in 16 strains (36Á4%) of both coagulase-positive and coagulase-negative staphylococci. This study highlights the emergence of cases of otitis externa determined by coagulase-negative staphylococcus strains and once more emphasizes the need for bacterial culture with species identi®cation and susceptibility testing of swab specimens from the ear canal in order to choose appropriate antimicrobial agents.

Thus arises the need to assess the antimicrobial therapy for patients with IRAS The study aims to evaluate antimicrobials prescriptions for patients diagnosed with HAI in the Adult ICU of a teaching hospital in Recife-PE in 2010. Methods: cross-sectional, descriptive, and retrospective study using the HAI reporting forms, prescriptions and medical records of patients aged from 18 years, in Adult ICU of the Instituto de Medicina IntegralProf. Fernando Figueira (IMIP). The variables analyzed in the study were gender, age, admission diagnosis, etiologic agent, Infection Related to Health Care, antibiotics, high and óbto. Data were collected from the analysis of HAI reporting forms, data collection form of HAI reporting forms and records and / or prescriptions. Results: the study population consisted of 31 notifications. The respiratory tract infections were the most frequent (80.6%). The microbiological confirmation was 83.9%, totaling 11 species of microorganisms, one of which being multiresistant. The use of 14 different antimicrobials was observed with monotherapy in a minority of cases. Only two patients underwent five schemes. Mistake regarding prescription was not observed, but misconceptions about some doses, intervals and as an association were highlighted.Conclusion: the indicators analyzed showed no significant discrepancies when compared with other national or international studies. One perceives the need for further studies on the use of antimicrobials.
