High-Level Multidrug-Resistant Escherichia coli Isolates from Wild Birds in a Large Urban Environment.

Intensive clinical use of antibiotics together with inadequate sanitation in an urban environment may contribute to the dissemination of multidrug-resistant (MDR) bacteria in the community. Wild birds living in these areas may become colonized with such organisms and further disseminate these resistant bacteria. In this study, we examined Escherichia coli isolates from the intestine of wild birds in Rio de Janeiro, Brazil, for those expressing extended-spectrum beta-lactamase (ESBL), carbapenemase, and other drug resistances.

Haemophilus influenzae serotype b and a capsule-deficient type mutant (b-) invasive disease in a partially vaccinated child in Brazil.

We report a rare case of infection by two different types of Haemophilus influenzae strains in a child who received only one dose of the H. influenzae serotype b (Hib) conjugate vaccine (DTwP+Hib). The strains were recovered from blood and cerebrospinal fluid (CSF) and were phenotypically identified as Hib and non-typable H.
