Molecular testing for gastrointestinal pathogens in intestinal tissue of infants with necrotizing enterocolitis or spontaneous intestinal perforation.

ABSTRACT:

Objective

The objective of this study was to determine the frequency of common gastrointestinal bacterial, parasitic, and viral pathogen detection in necrotizing enterocolitis (NEC) or spontaneous intestinal perforation (SIP) -associated intestinal tissue.

Study design

Retrospective cohort study examined formalin fixed, paraffin embedded (FFPE) surgical or autopsy intestinal tissue from NEC or SIP specimens. DNA and RNA were extracted and analyzed by multiplex PCR panel (GIFA Biofire). DNA or RNA from stool samples containing each pathogen were extracted for positive controls.

Results

The total number of intestinal tissue samples were 193 from 310 infants (156 NEC, 37 SIP). Six (3%) infants with stage III NEC tested positive for a target pathogen; 2, C. difficile; 3,
