ABSTRACT

Each year, emerging strains appear, increasing health care associated infection mortality. Seven cases of infections related to an outbreak due to Streptococcus uberis in an Intensive Care Unit (ICU) are presented.
Material and Methods. Case series, carried out in Hospital ISSSTECALI Mexicali, B.C., Mexico. Clinical record data were collected from patients infected with Streptococcus uberis. Multivariate analysis was performed, Pearson correlation, covariance, attack rate and lethality were estimated.
Results. During 2016 there were seven cases of pneumonia in the ICU, attack rate 0.1247/1000 discharges, average age 69 years, predominantly male gender (71%). Associated comorbidities chronic degenerative diseases. Five events of ventilator-associated pneumonia (71%). The bacterial phenotype of S. uberis showed two multidrug resistant strains. There was a direct correlation between advanced age and days of hospital stay as factors of poor prognosis, superinfection is favored by other nosocomial pathogens. The lethality was 0.0712/1000 discharges. Average hospital stay 28 days.
Conclusions. S. uberis associated infections are due to the selection of strains in the icu. Predispose to superinfection by aggressive and opportunistic pathogens with a poor prognosis. It generates an increase in the lethality rate associated with the antibiotic resistance index.
