Rhinoviruses as critical agents in severe bronchiolitis in infants.

Objectives: To detect RSV or other thirteen respiratory viruses as possible causer agent of bronchiolitis in infants.

Method: This is an epidemiological analytical study, conducted using a nasopharyngeal aspirate of 173 hospitalized children younger than two years old with severe bronchiolitis in three hospitals in the Campinas Metropolitan Region (CMR) during 2013-14. The data was statically evaluated by Pearson's chi-squared test with statistical significance of 0.

Biological studies and molecular characterization of a Cryptosporidium isolate from ostriches (Struthio camelus).

There are many reports of cryptosporidial infection in ostriches, but none with molecular characterization of the isolates. A study was undertaken for the characterization of a Brazilian Cryptosporidium sp. ostrich isolate by using molecular phylogenetic analysis of fragments of the 18S ribosomal DNA, heat-shock protein (hsp) 70 coding gene, and actin coding gene.
